The hypocenters of the earthquake and its aftershocks define a east-northeast striking, steeply northwest-dipping surface that projects up to the active surficial trace of the Raymond fault. One of the nodal planes of the focal mechanism of the earthquake parallels the Raymond fault with left-lateral strike-slip movement on that plane, and is consistent with geomorphic and paleoseismic evidence that the Raymond fault is dominantly a left-lateral strike-slip fault.

Values of CT at these sites were developed by a regression analysis that related rainfall-runoff model estimates of T-year floods to a sample set of 50 model calibrations. CT was regionalized via kriging to develop maps depicting its geographic variation for a large part of the United States east of the 105th meridian. Kriged estimates of CT and basin-runoff characteristics were used to compute regionalized T-year floods for 200 small drainage basins. Observed T-year flood estimates also were developed for these sites. Regionalized floods are shown to account for a large percentage of the variability in observed flood estimates with coefficients of determination ranging from 0.89 for 2-year floods to 0.82 for 100-year floods. The relative importance of the factors comprising regionalized flood estimates is evaluated in terms of scale (size of drainage area), basin-runoff characteristics (rainfall-runoff model parameters), and climate (CT).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Water Resources Association","doi":"10.1111/j.1752-1688.1990.tb01395.x","issn":"00431370","usgsCitation":"Lichty, R., and Karlinger, M., 1990, Climate factor for small-basin flood frequency: Water Resources Bulletin, v. 26, no. 4, p. 577-586, https://doi.org/10.1111/j.1752-1688.1990.tb01395.x.","startPage":"577","endPage":"586","numberOfPages":"10","costCenters":[],"links":[{"id":222988,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267740,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.1990.tb01395.x"}],"volume":"26","issue":"4","noUsgsAuthors":false,"publicationDate":"2007-06-08","publicationStatus":"PW","scienceBaseUri":"5059f651e4b0c8380cd4c6b4","contributors":{"authors":[{"text":"Lichty, R.W.","contributorId":46987,"corporation":false,"usgs":true,"family":"Lichty","given":"R.W.","affiliations":[],"preferred":false,"id":372406,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Karlinger, M.R.","contributorId":95039,"corporation":false,"usgs":true,"family":"Karlinger","given":"M.R.","affiliations":[],"preferred":false,"id":372407,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The area includes part of the volcanic sequence of the Keweenawan Supergroup south of Lake Superior, the southern margin of the Archean Superior Province, the accreted island-arc terranes of the Penokean Orogen, and the Wolf River batholith. Numerous dikes are evident in the shaded relief, some being more than 200 km in length. Many of the longer dikes are reversely magnetized Keweenawan diabase associated with early extension of the Midcontinent Rift; some apparently were intruded along preexisting faults. A northwest system of dikes and faults indicated by the shaded relief map may be related to later stages of Keweenawan rifting. The Wolf River batholith is characterized by low magnetic relief associated with the predominant granitoids but includes circular plutons of highly magnetic anorthosite and a large area of magnetic rock having a signature different from the mapped anorthosite bodies. A fault bounding the western side of the batholith is paralleled by an apparent system of faults or dikes in the older terrane to the west. The magnetic map covering the Wisconsin magmatic terranes and the Archean Superior Province margin to the north is dominated by east-northeast-trending Penokean rocks. Large units of magnetic mafic rocks and less magnetic granitoid rocks are cut by a system of well-defined northeast shear zones and a more easterly trending, possibly younger set of faults, some of which contain dikes along parts of their lengths. Although the sutures bounding the magmatic terranes generally follow the magnetic trends, they do not have distinctive magnetic signatures.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e90-156","issn":"00084077","usgsCitation":"King, E.R., 1990, Precambrian terrane of north-central Wisconsin: an aeromagnetic perspective: Canadian Journal of Earth Sciences, v. 27, no. 11, p. 1472-1477, https://doi.org/10.1139/e90-156.","productDescription":"6 p.","startPage":"1472","endPage":"1477","costCenters":[],"links":[{"id":223434,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wisconsin","otherGeospatial":"Lake Superior","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -87.66671060976584,\n              44.3610017587431\n            ],\n            [\n              -87.66671060976584,\n              46.373762217927776\n            ],\n            [\n              -92.90108864423792,\n              46.373762217927776\n            ],\n            [\n              -92.90108864423792,\n              44.3610017587431\n            ],\n            [\n              -87.66671060976584,\n              44.3610017587431\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"27","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8107e4b0c8380cd7b321","contributors":{"authors":[{"text":"King, E.

The magnetic and gravity maps show large amplitude positive anomalies associated with the shallow but largely buried section of Washington Coast Range mafic rocks which are separated by negative anomalies over deep sedimentary basins. The positive anomalies indicate that the Coast Range mafic basement extends farther east than previously thought, at least as far east as the longitude of Seattle. Linear and steep gravity and magnetic gradients indicate many unmapped, often buried faults in the Washington Coast Range Province. Magnetic highs are also associated with mapped batholiths in the Cascade arc. Several magnetic highs observed east of the Coast Range rocks and west of these batholiths may be associated with buried Tertiary plutons or ophiolites. Two-dimensional gravity and magnetic modeling constrained with geological and other geophysical data indicate that the Coast Range Province rocks are about 1 km thick at the coast, thickening to as much as 30 km near their postulated eastern edge.

Under these rocks may be mantle or a subduction complex composed of dense mafic, ultramafic, and sedimentary rocks like that proposed to underlie Vancouver Island. Previous gravity models of the Washington margin include lower densities for the proposed subduction complex than for Vancouver Island, suggesting a lower component of mafic and ultramafic rocks than the rocks underlying Vancouver Island. However, my Washington model requires that the proposed subduction complex be more dense than the trench sediments and, therefore, that material denser than sediments be incorporated within it. The absence of continental mantle and the modeled wedge shape of the Coast Range Province upper crust suggest that erosion of the bottom of the overriding plate by subduction processes may have occurred.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB095iB12p19533","issn":"01480227","usgsCitation":"Finn, C.A., 1990, Geophysical constraints on Washington convergent margin structure: Journal of Geophysical Research Solid Earth, v. 95, no.

These findings demonstrate the importance of off-axis hydrothermal activity and the role of the intersection of tectonic lineations in controlling hydrothermal sites at sea-floor spreading centers.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1990)018<0493:MOAHAO>2.3.CO;2","usgsCitation":"Rona, P.A., Denlinger, R.P., Fisk, M.R., Howard, K.J., Taghon, G.L., Klitgord, K.D., McClain, J.S., McMurray, G.R., and Wiltshire, J.C., 1990, Major off-axis hydrothermal activity on the northern Gorda Ridge: Geology, v. 18, no. 6, p. 493-496, https://doi.org/10.1130/0091-7613(1990)018<0493:MOAHAO>2.3.CO;2.","productDescription":"4 p.","startPage":"493","endPage":"496","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":297201,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","otherGeospatial":"Gorda Ridge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.37695312499999,\n              51.45400691005982\n            ],\n            [\n              -121.904296875,\n              51.781435604431195\n            ],\n            [\n              -123.3984375,\n              53.38332836757156\n            ],\n            [\n              -127.265625,\n              51.23440735163459\n            ],\n            [\n              -127.79296875,\n              49.66762782262194\n            ],\n            [\n              -125.15625000000001,\n              47.45780853075031\n            ],\n            [\n              -125.41992187499999,\n              43.644025847699496\n            ],\n            [\n              -125.68359374999999,\n              41.04621681452063\n            ],\n            [\n              -123.837890625,\n              37.16031654673677\n            ],\n            [\n              -118.21289062499999,\n              32.32427558887655\n            ],\n            [\n              -115.6640625,\n              32.62087018318113\n            ],\n            [\n              -121.37695312499999,\n              51.45400691005982\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"18","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2bece4b08de9379b3571","contributors":{"authors":[{"text":"Rona, Peter A.","contributorId":14912,"corporation":false,"usgs":false,"family":"Rona","given":"Peter","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":538254,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Denlinger, Roger P. 0000-0003-0930-0635 roger@usgs.gov","orcid":"https://orcid.org/0000-0003-0930-0635","contributorId":2679,"corporation":false,"usgs":true,"family":"Denlinger","given":"Roger","email":"roger@usgs.gov","middleInitial":"P.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"preferred":true,"id":538255,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fisk, M.

The surface of the belt is ornamented by large (5 m), migrating tidal bars, oriented in a north-south direction, on which sand waves, oriented in an east-west direction, are superimposed. Some of the sand waves are awash at low tide. The sand waves are formed by strong reversing tidal currents flowing between the Gulf of Mexico and the Straits of Florida. The waves migrate directly over Pleistocene bedrock to the east, but the deposit thickens to the west and sand waves there overlie non-oolitic Holocene accumulations as thick as 12 m. Westward-dipping accretionary bedding indicates that net migration of the sands is to the west, despite north-south movement of tidal currents. The westward edge of the accumulation has accreted over deeper, muddier deposits. Although tidal currents and resultant bedforms appear identical to those of active ooid deposits in the Bahamas and elsewhere, no oolitically coated grains were found in this study. Thin-section analyses show the principal component (average 48%) of the sands is fragmented plates of species of the green alga Halimeda , followed by particulate coral (average 17%), which increases off the flanks of the main sand body.

Faults of this zone have been intermittently active from Middle Proterozoic to Holocene time, and because of numerous tectonic overprints, controversy continues about displacement directions and times of displacement along specific faults. Geologic mapping shows evidence that many principal faults of the Lewis and Clark line, such as the St. Marys-Helena Valley, Bald Butte, Ninemile, and Osburn faults, had right separation or slip that ranged between 28 and 11 km, and this displacement probably occurred during Late Cretaceous time. Other faults, such as the Elevation Mountain, Placer Creek, and Ranch Creek faults, have Late Cretaceous right separations that range between 8 and 3.2 km, and the Mount Sentinel fault zone has between 6.5 and 3 km of right separation of probable Late Cretaceous age.</p><p>Subsidiary structures of the Lewis and Clark line postdate Paleozoic and Lower Cretaceous rocks and predate Late Cretaceous stocks at some places; subsidiary faults and folds that have age constraints have slip directions compatible with right slip along adjacent, principal faults.</p><p>Sedimentation patterns of Lower and Upper Cretaceous rocks indicate that faults of the Lewis and Clark line fragmented the foredeep region of the foreland basin into separate northern and southern basins in Late Cretaceous time. The Lower and Upper Cretaceous Blackleaf Formation (Albian and lower Cenomanian) was deposited in a continuous foredeep basin that extended across the Lewis and Clark line from north of the Canadian border to southwestern Montana, a distance of about 450 km. North of the Lewis and Clark line, middle and upper Cenomanian rocks are absent, and a thin sequence of uppermost Cenomanian to Campanian rocks was deposited in a marine environment that changed to a strand-line and continental environment in early Campanian time. South of the Lewis and Clark line, middle and upper Cenomanian deposits are also absent, but a thick sequence of Turonian-to-Campanian rocks was deposited in brackish water and strand-line environments, and during later Campanian time, in a continental environment. In the region between the St. Marys-Helena Valley and Bald Butte faults, a barrier may have formed that served as a local sediment source between foredeep regions in the northern and southern foreland basin during the period 91 to 75 Ma. South of the Bald Butte fault, an extensional tectonic regime contributed to a higher sediment-accumulation rate in the foredeep region along the north border of the southern basin (30 cm/1,000 yr), as compared to lower sediment-accumulation rates (6.9 and 7.8 cm/ 1,000 yr) in the foredeep region of the south part of the northern basin.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1990)102<1021:FOTCPO>2.3.CO;2","usgsCitation":"Wallace, C.A., Lidke, D., and Schmidt, R.G., 1990, Faults of the central part of the Lewis and Clark line and fragmentation of the Late Cretaceous foreland basin in west-central Montana: Geological Society of America Bulletin, v. 102, no. 8, p. 1021-1037, https://doi.org/10.1130/0016-7606(1990)102<1021:FOTCPO>2.3.CO;2.","productDescription":"17 p.","startPage":"1021","endPage":"1037","numberOfPages":"17","costCenters":[],"links":[{"id":223131,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -113.93105489049955,\n              47.74152319336437\n            ],\n            [\n              -113.93105489049955,\n              45.78512955401325\n            ],\n            [\n              -109.9320314529997,\n              45.78512955401325\n            ],\n            [\n              -109.9320314529997,\n              47.74152319336437\n            ],\n            [\n              -113.93105489049955,\n              47.74152319336437\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"102","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0f27e4b0c8380cd537d2","contributors":{"authors":[{"text":"Wallace, C.

Modelling suspended sediment concentration and transport rate during storms","docAbstract":"Long-term near-bottom wave and current observations and a one-dimensional sediment transport model are used to calculate the concentration and transport of sediment during winter storms at 60-80 m water depth along the southern flank of Georges Bank and in the Mid-Atlantic Bight. Calculations are presented for five stations, separated by more than 600 km alongshelf, that have different bottom sediment texture, bedforms and current conditions. A modified version of the sediment transport model presented by Grant and Glenn (1983, Technical Report to the American Gas Association), Glenn (1983, D.Sc. Thesis, M.I.T.), and Glenn and Grant (1987, Journal of Geophysical Research, 92, 8244-8264) is used to examine the influence of wave-current interaction, sediment stratification, and limitations on the erodibility of the bottom sediments on the concentration of sediment in the water column and on transport. Predicted suspended sediment concentrations are higher than observed, based on beam transmissometer measurements, unless an erosion limit of order a few millimeters for sediments finer than 94 ??m is imposed. The agreement between predicted and measured beam attenuation is better at stations that have significant amounts of silt plus clay in the surficial sediments than for stations with sandy sediments. Sediment concentrations during storms estimated by Moody et al. (1987, Continental Shelf Research, 7, 609-628) are within 50% of the model predictions. Sediment transport rates for sediments 94 ??m and finer are determined largely by the concentrations in the surficial sediment and the erosion depth limit.

The provinces are climatically similar. The soil moisture regime is udic. The soil temperature regime is typically thermic from Virginia through Georgia, although it is mesic at altitudes above 400 m in Georgia and above 320 m in Virginia. The soil temperature regime is mesic for the Piedmont and Coastal Plain from Maryland through New Jersey. The tightly folded, structurally complex crystalline rocks of the Piedmont and the gently dipping “layer-cake” clastic sedimentary rocks and sediments of the Coastal Plain respond differently to weathering, pedogenesis, and erosion. The different responses result in two physiographically contrasting terrains; each has distinctive near-surface hydrology, regolith, drainage morphology, and morphometry.</p><p>The Piedmont is predominantly an erosional terrain. Interfluves are as narrow as 0.5 to 2 km, and are convex upward. Valleys are as narrow as 0.1 to 0.5 km and generally V-shaped in cross section. Alluvial terraces are rare and discontinuous. Soils in the Piedmont are typically less than 1 m thick, have less sand and more clay than Coastal Plain soils, and generally have not developed sandy epipedons. Infiltration rates for Piedmont soils are low at 6–15 cm/h. The soil/saprolite, soil/rock, and saprolite/rock boundaries are distinct (can be placed within 10 cm) and are characterized by ponding and/or lateral movement of water. Water movement through soil into saprolite, and from saprolite into rock, is along joints, foliation, bedding planes and faults. Soils and isotopic data indicate residence times consistent with a Pleistocene age for most Piedmont soils.</p><p>The Coastal Plain is both an erosional and a constructional terrain. Interfluves commonly are broader than 2 km and are flat. Valleys are commonly as wide as 1 km to greater than 10 km, and contain numerous alluvial and estuarine terrace sequences that can be correlated along valleys for tens of kilometers. Coastal Plain soils are typically as thick as 2 to 8 m, have high sand content throughout, and have sandy epipedons. These epipedons consist of both A and E horizons and are 1 to 4 m thick. In Coastal Plain soils, the boundaries are transitional between the solum and the underlying parent material and between weathered and unweathered parent material. Infiltration rates for Coastal Plain soils are typically higher at 13–28 cm/h, than are those for Piedmont soils. Indeed, for unconsolidated quartz sand, rates may exceed 50 cm/h. Water moves directly from the soil into the parent material through intergranularpores with only minor channelization along macropores, joints, and fractures. The comparatively high infiltration capacity results in relatively low surface runoff, and correspondingly less erosion than on the Piedmont uplands.</p><p>Due to differences in Piedmont and Coastal Plain erosion rates, topographic inversion is common along the Fall Zone; surfaces on Cenozoic sedimentary deposits of the Coastal Plain are higher than erosional surfaces on regolith weathered from late Precambrian to early Paleozoic crystalline rocks of the Piedmont. Isotopic, paleontologic, and soil data indicate that Coastal Plain surficial deposits are post-middle Miocene to Holocene in age, but most are from 5 to 2 Ma. Thus, the relatively uneroded surfaces comprise a Pliocene landscape. In the eastern third of the Coastal Plain, deposits that are less than 3.5 Ma include alluvial terraces, marine terraces and barrier/back-barrier complexes as morphostratigraphic units that cover thousands of square kilometers. Isotopic and soil data indicate that eastern Piedmont soils range from late Pliocene to Pleistocene in age, but are predominantly less than 2 Ma old. Thus, the eroded uplands of the Piedmont “peneplain” comprise a Pleistocene landscape.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0169-555X(90)90015-I","issn":"0169555X","usgsCitation":"Markewich, H.W., Pavich, M.J., and Buell, G.R., 1990, Contrasting soils and landscapes of the Piedmont and Coastal Plain, eastern United States: Geomorphology, v. 3, no. 3-4, p. 417-447, https://doi.org/10.1016/0169-555X(90)90015-I.","productDescription":"31 p.","startPage":"417","endPage":"447","costCenters":[],"links":[{"id":223136,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fa7ce4b0c8380cd4db0e","contributors":{"authors":[{"text":"Markewich, Helaine W. 0000-0001-9656-3243 helainem@usgs.gov","orcid":"https://orcid.org/0000-0001-9656-3243","contributorId":2008,"corporation":false,"usgs":true,"family":"Markewich","given":"Helaine","email":"helainem@usgs.gov","middleInitial":"W.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":372184,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pavich, Milan J. mpavich@usgs.gov","contributorId":2348,"corporation":false,"usgs":true,"family":"Pavich","given":"Milan","email":"mpavich@usgs.gov","middleInitial":"J.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":372186,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Buell, Gary R. grbuell@usgs.gov","contributorId":3107,"corporation":false,"usgs":true,"family":"Buell","given":"Gary","email":"grbuell@usgs.gov","middleInitial":"R.","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":372185,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Granitoids widely emplaced within these supracrustal rocks range from 1.76 to 1.64 Ga. The earlier plutons and surrounding supracrustal rocks were metamorphosed to granulite and high amphibolite facies throughout the province at about 1705 Ma in a migmatite-producing event that we term (informally) the Ivanpah orogeny. Subsequent granitoids, emplaced from 1.69 to 1.67 Ga, were voluminous along a north trending belt in the middle of the Mojave province. Younger plutons were emplaced at about 1.66 Ga in several places and at about 1.64 Ga along the extreme southern part of the province.

Framework-grain summaries for 50 thin sections from sandstones of the Krebs, Cabaniss, and Marmaton Groups and their surface and subsurface equivalents were subjected to multivariate statistical analyses to establish regional compositional trends for provenance analysis. R-mode cluster and correspondence analyses were used to determine the contributing effect (total variance) of key framework grains. Fragments of monocrystalline and polycrystalline quartz; potassium and plagioclase feldspar; chert; and metamorphic, limestone, and mudstone-sandstone rock fragments contribute most to the variation in the grain population. Q-mode cluster and correspondence analyses were used to identify four petrofacies and establish the range of compositional variation in Desmoinesian sandstones. Petrofacies I is rich in monocrystalline quartz (78-98%); mica and rock fragments are rare. Petrofacies II is also rich in monocrystalline quartz (60-84%) and averages 12% total rock fragments. Petrofacies III and IV are compositionally heterogeneous and contain variable percentages of monocrystalline and polycrystalline quartz, potassium feldspar, mica, chert, and metamorphic and sedimentary rock fragments. Quantitative analyses indicate that Desmoinesian sandstones were derived from sedimentary, igneous, and metamorphic source areas. Sandstones of petrofacies I and II occur mostly in the lower Desmoinesian and are widely distributed, although they are most abundant in eastern and central Oklahoma; sandstones of petrofacies III and IV are widely distributed and occur primarily in the middle and upper Desmoinesian. The range of compositional variation and the distribution of petrofacies are related to paleotectonics and basin development, sediment recycling, and varying depositional environments.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Anadarko Basin symposium, 1988 (Circular 90)","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Oklahoma Geological Survey","publisherLocation":"Norman, OK","collaboration":"Proceedings of a symposium held April 5-6, 1988, at Norman, Oklahoma; cosponsored by the Oklahoma Geological Survey and the U.S. Geological Survey","usgsCitation":"Dyman, T.S., 1989, Quantitative petrographic analysis of Desmoinesian sandstones from Oklahoma, chap. <i>of</i> Anadarko Basin symposium, 1988 (Circular 90), p. 162-175.","productDescription":"14 p.","startPage":"162","endPage":"175","costCenters":[],"links":[{"id":268681,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268680,"type":{"id":11,"text":"Document"},"url":"https://www.ogs.ou.edu/pubsscanned/Circulars/Circular90.pdf"}],"country":"United States","state":"Oklahoma","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -103.0,33.62 ], [ -103.0,37.0 ], [ -94.43,37.0 ], [ -94.43,33.62 ], [ -103.0,33.62 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51347f0ae4b0e1603e4fec66","contributors":{"authors":[{"text":"Dyman, Thaddeus S.","contributorId":83971,"corporation":false,"usgs":true,"family":"Dyman","given":"Thaddeus","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":475306,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Inferred directions of maximum horizontal principal stress (SH<sub>max</sub>) are ENE for the eastern Anadarko basin, and NE for the Marietta basin and the Bravo dome area. For the Bravo dome area, the magnitudes of the three principal stresses (S<sub>1</sub>, S<sub>2</sub>, S<sub>3</sub>) are known from existing hydraulic-fracturing (hydrofrac) measurements, and a normal-faulting stress regime (S<sub>V</sub> > SH<sub>max</sub> > SH<sub>min</sub>) is implied. For the eastern Anadarko basin and the Marietta basin, the magnitudes of the principal stresses are not known. Because Quaternary left-lateral oblique slip on the Meers fault in south-central Oklahoma suggests strike-slip (SHmax > Sv > SHmin) and reverse faulting (SH<sub>max</sub> > SH<sub>min</sub> > S<sub>V</sub>), the study region is inferred to be a possible transition zone between areas of extensional and compressional stresses. Breakout data from the eastern Anadarko basin yield a single consistent SH<sub>max</sub> orientation. Data from the Marietta basin and the Bravo dome area have bimodal-orthogonal distributions consisting of breakouts and orthogonal sets of well-bore enlargement orientations. Orthogonal trends in the data are probably related to drilling-induced hydraulic fracturing of the well bore, or to preexisting natural fractures or joint sets intersecting the well bore. On the dipmeter log, breakouts and fracture enlargements have elliptical cross sections of similar size and shape. Orthogonally oriented well-bore enlargements are differentiated by comparing their long-axis orientations with directions of known or inferred horizontal stress. Dispersion, or data scatter, among enlargement orientations (bimodal data sets) increases the standard deviations for many well data sets from the Marietta basin and the Bravo dome area. In these two areas, some dispersion may reflect variation in stress conditions across fault-bounded blocks and the orientations of fractures or joints within these blocks. Although breakouts and fracture enlargements formed in all parts of the thick sequences of sedimentary rocks logged, they occurred primarily in limestone, shale, and dolomitic rocks, reflecting the abundance of these rock types in the study areas.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Anadarko Basin symposium, 1988 (Circular 90)","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Oklahoma Geological Survey","publisherLocation":"Norman, OK","collaboration":"Proceedings of a symposium held April 5-6, 1988, at Norman, Oklahoma; cosponsored by the Oklahoma Geological Survey and the U.S. Geological Survey","usgsCitation":"Dart, R.L., 1989, Horizontal stresses from well-bore breakouts and lithologies associated with their formation, Oklahoma and Texas Panhandle, chap. <i>of</i> Anadarko Basin symposium, 1988 (Circular 90), p. 97-120.","productDescription":"24 p.","startPage":"97","endPage":"120","costCenters":[],"links":[{"id":268673,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268672,"type":{"id":11,"text":"Document"},"url":"https://www.ogs.ou.edu/pubsscanned/Circulars/Circular90.pdf"}],"country":"United States","state":"Oklahoma;Texas","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -104.0,33.0 ], [ -104.0,38.0 ], [ -94.0,38.0 ], [ -94.0,33.0 ], [ -104.0,33.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51347f07e4b0e1603e4fec54","contributors":{"authors":[{"text":"Dart, Richard L. dart@usgs.gov","contributorId":1209,"corporation":false,"usgs":true,"family":"Dart","given":"Richard","email":"dart@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":475300,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The Lewis Cliff ice tongue (84&deg;15'S 161&deg;25'E) is a meteorite-stranding surface of ablating blue ice, about 2.3 by 7.0 kilo-meters, bounded on the west by the Lewis Cliff, on the northand northeast by a large supraglacial moraine, and on the eastby the Colbert Hills.

The 600-km length of the Coast Ranges boundary shares a common structural setting that involves westward upturn of Cenozoic and Cretaceous strata at the eastern front of the Coast Ranges and a major, southwest facing step in the basement surface beneath the western Great Valley. Like Coalinga anticline, Pliocene and Quaternary folding and faulting along the rest of the boundary also result from northeast–southwest compression acting nearly perpendicular to the strike of the San Andreas fault.

A compilation of the age of shelf drowning (carbonate-to-shale transition) reveals the degree to which orogeny was diachronous both across and along strike. Shelf drowning occurred first at the northern end of the orogen in Newfoundland, then at the southern end of the orogen in Georgia, and finally in Quebec. Diachronism is attributed to oblique collision between an irregular passive margin, that had a deep embayment in Quebec, and at least one east dipping subduction complex. The rate of plate convergence during collision is estimated at 1 to 2 cm/yr, and the minimum width of the ocean that closed is estimated at 500 to 900 km. Far-traveled deepwater sequences in the thrust belt contain anomalously old Taconic flysch, related to early arrival of the continental slope/rise at a west advancing trench then located far to the east. The drowning isochron map provides a new basis for estimating tectonic transport distances of four of these allochthons (about 165 to 450 km), results not readily obtained by conventional structural analysis.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/TC008i005p01037","issn":"02787407","usgsCitation":"Bradley, D.C., 1989, Taconic plate kinematics as revealed by foredeep stratigraphy, Appalachian orogen: Tectonics, v. 8, no. 5, p. 1037-1049, https://doi.org/10.1029/TC008i005p01037.","productDescription":"13 p.","startPage":"1037","endPage":"1049","costCenters":[],"links":[{"id":224307,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","otherGeospatial":"Appalachian Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -59.94794184613204,\n              53.783005810210994\n            ],\n            [\n              -66.52193972184966,\n              49.42391661877889\n            ],\n            [\n              -84.05589482730278,\n              32.29826164743447\n            ],\n            [\n              -82.25406401000738,\n              31.27460409801749\n            ],\n            [\n              -72.41174206402178,\n              42.00001551829209\n            ],\n            [\n              -60.01457676108012,\n              51.99456174559443\n            ],\n            [\n              -59.94794184613204,\n              53.783005810210994\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"8","issue":"5","noUsgsAuthors":false,"publicationDate":"2010-07-26","publicationStatus":"PW","scienceBaseUri":"505ba3ace4b08c986b31fdee","contributors":{"authors":[{"text":"Bradley, D.

Surveys were conducted in uncut (control) and clear-cut (treatment) plots in three stand types: conifer, hardwood, and mixed growth.  We used a mark-recapture model and its associated jackknife species richness estimator (N), as an indicator of avian community structure.  Increases in estimated richness (N) and Shannon - Weaver diversity (H') were noted in the treated hardwood and mixed growth, but not in the conifer stands.  Seventeen avian species increased in relative abundance, whereas two species declined.  Stand treatment was associated with important changes in bird species composition.  Increased habitat patchiness and the creation of forest edge are hypothesized as causes for the greater estimates of richness and diversity.","language":"English","publisher":"Canadian Science

The purpose of our review was to examine available data on population trends and current status of black ducks and trends in natality and survival and to relate these, where possible, to changes in habitat, predation, disease, contaminants, harvest, and hybridization with mallards.  2. The number of black ducks tallied in the winter survey has declined steadily over the past 30 years at an average rate of about 3%/ year. Reliability and precision of the survey are uncertain; it may not provide an adequate index to the continental population of black ducks. Breeding surveys are incomplete and sporadic, but black ducks have decreased in Ontario and increased in the Maritime Provinces and Quebec.  3. Recent declines in numbers of black ducks tallied in the winter survey are not unusual in magnitude or much different from those that have occurred among several other species of waterfowl.  4. At present, black ducks are not especially scarce relative to numbers of several other ducks in eastern North America.  5. There is no solid evidence of major decreases in quality or quantity of breeding habitat for black ducks in recent years; in some areas, habitat has improved.  6. Natural mortality of black ducks has not been well studied, but does not seem unusually high compared to other dabbling ducks.  7. Harvest rates of black ducks are similar to those of sympatric mallards as determined by banding analyses.  8. There is no strong evidence for direct effects of contaminants on black ducks, but some indirect effects through invertebrate food resources have been detected.  9. Age ratios in black ducks show no trend in the past 18 years.  10. The quality and quantity of wintering habitat for black ducks have decreased substantially in some areas.  11. Disease and other natural mortality that affect black ducks do .not occur in unusually high frequency.  12. A decline in harvest of black ducks has occurred; most of the decline has been in the United States, especially since restrictive regulations were implemented in 1983.  13. Recovery rates of black ducks have declined recently in the U.S., but not in Canada.  14. Survival rates of black ducks are 56-63% for adults and 43% for young. These rates of survival are similar to comparable estimates in sympatric mallards.  15. Long hunting seasons may depress survival in some sex-age classes of black ducks, buteffects of small reductions in survival on population trends are unknown.  16. Available evidence does not support the contention that hunting is either the sole or most important cause of the decline in the winter tally of black duck numbers.  17. Surveys and banding of black ducks should be thoroughly reviewed and maintained or improved as warranted. Obtaining or maintaining a reasonable index to numbers of black ducks is the top priority among survey needs.  18. Experimental manipulation of hunting seasons should be considered to elucidate relationships among regulations, harvest, survival, and population trends.  19. Black ducks and mallards are genetically similar; there is as much genetic differentiation within the 2 species as there is between them.  20. Black duck x mallard hybrids are fertile. Hybrids are difficult to detect by plumage and thus published frequencies (0-13%) of hybrids may be low.  21. Hybridization could be a result of concomitant mallard increases and black duck decreases, or changes in black duck-to-mallard ratios could be from hybridization and genetic swamping of black ducks.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"Rusch, D., Ankney, C., Boyd, H., Longcore, J.R., Montalbano, F., Ringelman, J., and Stotts, V.D., 1989, Population ecology and harvest of the American black duck: a review: Wildlife Society Bulletin, v. 17, no. 4, p. 379-406.","productDescription":"379-406","startPage":"379","endPage":"406","numberOfPages":"28","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194197,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17904,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.jstor.org/stable/3782702","linkFileType":{"id":5,"text":"html"}}],"volume":"17","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db684010","contributors":{"authors":[{"text":"Rusch, D.

Most permanent residents and temperate-zone migrants did not show a general pattern of decrease during this period.  Field data from Mexico were used to classify a subset of the neotropical migrants as using forest or scrub habitats during winter.  Population declines during 1978-1987 were significantly greater among the forest-wintering species, while populations of scrub-wintering species increased.  The same subset of neotropical migrants also showed overall declines in forest-breeding species, but no significant differences existed between species breeding in forest and scrub habitats.  Neotropical migrant species that primarily use forested habitats in either wintering or breeding areas are declining, but a statistically significant association between habitat and population declines was detected only in the tropics.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the National Academy of Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"3808_Robbins.pdf","usgsCitation":"Robbins, C., Sauer, J., Greenberg, R., and Droege, S., 1989, Population declines in North American birds that migrate to the neotropics: Proceedings of the National Academy of Sciences, v. 86, no. 19, p. 7658-7662.","productDescription":"7658-7662","startPage":"7658","endPage":"7662","numberOfPages":"5","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":94268,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://www.pnas.org/content/86/19/7658.abstract","linkFileType":{"id":5,"text":"html"}},{"id":17903,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://www.pubmedcentral.nih.gov/picrender.fcgi?artid=298126&blobtype=pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":193697,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"86","issue":"19","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db68430a","contributors":{"authors":[{"text":"Robbins, C.S.","contributorId":53907,"corporation":false,"usgs":true,"family":"Robbins","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":336016,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sauer, J.R. 0000-0002-4557-3019","orcid":"https://orcid.org/0000-0002-4557-3019","contributorId":66197,"corporation":false,"usgs":true,"family":"Sauer","given":"J.R.","affiliations":[],"preferred":false,"id":336018,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Greenberg, R.S.","contributorId":27158,"corporation":false,"usgs":true,"family":"Greenberg","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":336015,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Droege, Sam 0000-0003-4393-0403","orcid":"https://orcid.org/0000-0003-4393-0403","contributorId":64185,"corporation":false,"usgs":true,"family":"Droege","given":"Sam","affiliations":[{"id":50464,"text":"Eastern Ecological Science Center","active":true,"usgs":true}],"preferred":false,"id":336017,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Thickness patterns and paleocurrent indicators show that the sediment forming this sequence was transported primarily southeastward and deposited in a southeast-trending, lobe-shaped body. Evidently, the sediment was carried from the shelf by sediment-gravity flows that travelled westward down the slope and then turned southeastward upon reaching a southeast-trending basin at the base of the slope. Data derived from the study of this basin, which paralleled the shelf edge and is thought to have formed parallel to a southeast-oriented segment of the Early Permian continental margin, constitute one of the most important arguments favoring a Pennsylvanian to Early Permian age of truncation of the western North American continental margin.&nbsp;</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0037-0738(89)90080-8","issn":"00370738","usgsCitation":"Stevens, C., Lico, M.S., and Stone, P., 1989, Lower Permian sediment-gravity-flow sequence, eastern California: Sedimentary Geology, v. 64, no. 1-3, p. 1-12, https://doi.org/10.1016/0037-0738(89)90080-8.","productDescription":"12 p.","startPage":"1","endPage":"12","costCenters":[],"links":[{"id":223721,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"eastern California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.25036992550474,\n              36.24083341099646\n            ],\n            [\n              -116.25036992550474,\n              35.348277037935134\n            ],\n            [\n              -114.89567591529288,\n              35.348277037935134\n            ],\n            [\n              -114.89567591529288,\n              36.24083341099646\n            ],\n            [\n              -116.25036992550474,\n              36.24083341099646\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"64","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4a72e4b0c8380cd68d88","contributors":{"authors":[{"text":"Stevens, C.H.","contributorId":16102,"corporation":false,"usgs":true,"family":"Stevens","given":"C.H.","affiliations":[],"preferred":false,"id":371152,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lico, Michael S.","contributorId":75897,"corporation":false,"usgs":true,"family":"Lico","given":"Michael","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":371153,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stone, Paul 0000-0002-1439-0156 pastone@usgs.gov","orcid":"https://orcid.org/0000-0002-1439-0156","contributorId":273,"corporation":false,"usgs":true,"family":"Stone","given":"Paul","email":"pastone@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":371154,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Interdisciplinary studies of a 334 m-long cored section from the town of Tulelake, California, near the center of the basin, document a 3-m.y. record of environmental changes. The core consists of a thick sequence of diatomaceous clayey, silty, and marly lacustrine sediments interbedded with numerous tephra layers. Paleomagnetic study puts the base of the core at about 3.0 Ma. Twelve widespread silicic tephra units provide correlations with other areas and complement age control provided by magnetostratigraphy; mafic and silicic tephra units erupted from local sources are also common in the core. Widespread tephra units include the Llao Rock pumice (=Tsoyawata, 7 ka), the Trego Hot Springs Bed (23 ka), and the Rockland (0.40 Ma), Lava Creek (0.62 Ma), and Rio Dell (1.5 Ma) ash beds, as well as several ash beds also found at Summer Lake, Oregon, and an ash bed originally recognized in DSDP hole 173 in the northeastern Pacific. Several tephra layers found in the core also occur in lacustrine beds exposed around the margins of the basin and elsewhere in the ancestral lacustrine system.</span></p><p><span>Diatoms are present throughout the section. Pollen is present in most of the section, but some barren zones are found in the interval between 50 and 140 m; the greatest change in behavior of the pollen record takes place just above the top of the Olduvai Normal-Polarity Subchronozone. Ostracodes are present only in high-carbonate (&gt;10% CaCO<sub>3</sub>) intervals. Evolutionary changes are found in the diatom and ostracode records. Bulk geochemical analyses show significant changes in elemental composition of the sediment through time.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0031-0182(89)90134-X","issn":"00310182","usgsCitation":"Adam, D., Sarna-Wojcicki, A., Rieck, H.J., Bradbury, J., Dean, W., and Forester, R.M., 1989, Tulelake, California: The last 3 million years: Palaeogeography, Palaeoclimatology, Palaeoecology, v. 72, p. 89-103, https://doi.org/10.1016/0031-0182(89)90134-X.","productDescription":"15 p.","startPage":"89","endPage":"103","costCenters":[],"links":[{"id":224141,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"Tulelake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.590433212109,\n              42.001532888963766\n            ],\n            [\n              -121.590433212109,\n              41.82182577352725\n            ],\n            [\n              -121.39683255075273,\n              41.82182577352725\n            ],\n            [\n              -121.39683255075273,\n              42.001532888963766\n            ],\n            [\n              -121.590433212109,\n              42.001532888963766\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"72","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb8bae4b08c986b327a2b","contributors":{"authors":[{"text":"Adam, D.P.","contributorId":14815,"corporation":false,"usgs":true,"family":"Adam","given":"D.P.","email":"","affiliations":[],"preferred":false,"id":370390,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sarna-Wojcicki, A.M. 0000-0002-0244-9149","orcid":"https://orcid.org/0000-0002-0244-9149","contributorId":104022,"corporation":false,"usgs":true,"family":"Sarna-Wojcicki","given":"A.M.","affiliations":[],"preferred":false,"id":370394,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rieck, Hugh J.","contributorId":44560,"corporation":false,"usgs":true,"family":"Rieck","given":"Hugh","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":370391,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bradbury, J.P.","contributorId":14431,"corporation":false,"usgs":true,"family":"Bradbury","given":"J.P.","email":"","affiliations":[],"preferred":false,"id":370389,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dean, W.E.","contributorId":97099,"corporation":false,"usgs":true,"family":"Dean","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":370393,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Forester, R.
