To make predictions about anthropogenic impacts on forests, we need to understand how these factors affect tree growth. In this study the effect of disturbance history on tree growth and stand structure was examined by using a computer model of forest development. The model was run under the climatic conditions of east Tennessee, USA, and the results compared to stand structure and tree growth data from a yellow poplar-white oak forest. Basal area growth and forest biomass were more accurately projected when rough approximations of the thinning and fire history typical of the measured plots were included in the simulation model. Stand history can influence tree growth rates and forest structure and should be included in any attempt to assess forest impacts.\r\n","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/BF01867163","usgsCitation":"Dale, V., and Doyle, T., 1987, The role of stand history in assessing forest impacts: Environmental Management, v. 11, no. 3, p. 351-357, https://doi.org/10.1007/BF01867163.","productDescription":"p. 351-357","startPage":"351","endPage":"357","numberOfPages":"7","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":134423,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":15415,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1007/BF01867163","linkFileType":{"id":5,"text":"html"},"description":"7124.000000000000000"}],"volume":"11","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2de4b07f02db61423b","contributors":{"authors":[{"text":"Dale, V.H.","contributorId":27021,"corporation":false,"usgs":true,"family":"Dale","given":"V.H.","email":"","affiliations":[],"preferred":false,"id":312060,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Doyle, T.W. 0000-0001-5754-0671","orcid":"https://orcid.org/0000-0001-5754-0671","contributorId":16783,"corporation":false,"usgs":true,"family":"Doyle","given":"T.W.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":312059,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The carbon dioxide has accumulated in a dome that is located on the extension of a linear chain of volcanic activity. A magmatic origin for the fluid is suggested by the geological setting, δ<sup>13</sup>C<sub>PDB</sub><span>&nbsp;</span>of –4.0‰, for the CO<sub>2</sub><span>&nbsp;</span>(where PDB represents the carbon-isotope standard), and a relatively high<span>&nbsp;</span><sup>3</sup>He component of the contained helium and high<span>&nbsp;</span><sup>3</sup>He/C ratio (6.4 x 10<sup>−10</sup>). The<span>&nbsp;</span><sup>3</sup>He/<sup>4</sup>He and He/Ne ratios are 3.0 and &gt; 1,370 times those of air, respectively. The CO<sub>2</sub>, as collected at the Earth's surface at 29.5 °C and 75 bar, expands more than 300-fold to form a gas at 1 atm and 22 °C. We suggest that liquid CO<sub>2</sub><span>&nbsp;</span>or high-density CO<sub>2</sub><span>&nbsp;</span>fluid (the critical point is 31.1 °C, 73.9 bar) of volcanic origin that expands explosively from shallow levels in the Earth's crust may be a major contributor to 'phreatic' volcanic eruptions and maar formation. Less violent release of magmatic CO<sub>2</sub><span>&nbsp;</span>into crater lakes may cause gas bursts with equally disastrous consequences such as occurred at Lake Nyos, Cameroon, in August 1986.</p></div></div>","language":"English","publisher":"Nature Publishing Group ","doi":"10.1038/326587a0","issn":"00280836","usgsCitation":"Chivas, A., Barnes, I., Evans, W.C., Lupton, J., and Stone, J., 1987, Liquid carbon dioxide of magmatic origin and its role in volcanic eruptions: Nature, v. 326, no. 6113, p. 587-589, https://doi.org/10.1038/326587a0.","productDescription":"3 p.

Willwood paleosols vary considerably in their relative degrees of maturity; maturity is defined as stage of development as a function of the amount of time required to form. Five arbitrary stages are proposed to distinguish these soils of different maturities in the Willwood Formation. Stage 1 soils, the least mature, are entisols; stage 2 and stage 3 soils are intermediate in maturity and are probably alfisols; and stage 4 and stage 5 soils, the most mature, are spodosols. These stages are not only time-progressive elements of an in situ maturation sequence for Willwood soil formation, but, in the lateral dimension, they are also usually distributed sequentially. Study of Willwood paleosols indicates that an inverse relationship exists between soil maturity and short-term sediment accumulation rate. The least mature Willwood paleosols formed in areas of relatively high net rates of sediment accumulation on 1) channel, levee, and crevasse-splay sediments of the proximal alluvial ridge, and 2) deposits filling large and small paleovalleys formed by major episodes of gullying (lowered baselevels). In contrast, the fine-grained sediments of the distal floodplain, where net sediment accumulation rates were relatively low, experienced development of much more mature soils. Soils of intermediate maturities occur in the order of their stage on intervening proximal floodplain and distal alluvial ridge sediments. Adjacent bodies of sedimentary rock that differ in their ancient soil properties because of distance from areas of relatively high sediment accumulation are denoted by the new term pedofacies . The remarkable sequence of paleosols in the Willwood Formation clearly illustrates several important principles of soil-sediment interrelationships in aggrading alluvial systems that have broad application to other deposits. This is especially true in view of the widespread distribution of paleosols in nearly all ancient fluvial rocks. Further study of Willwood paleosols will not only enable precise lateral correlation of coeval alluvial sediments, and thereby fluvial sedimentary events, from the distal to the proximal realms of the floodplain but will also contribute to increasingly informative evaluations of the nature, tempo, and mode of alluvial succession.</p></div></div>","language":"English","publisher":"SEPM","doi":"10.1306/212F8BB1-2B24-11D7-8648000102C1865D","issn":"00224472","usgsCitation":"Bown, T.M., and Kraus, M.J., 1987, Integration of channel and floodplain suites.

The subdued, vegetated moraines of the older group have been found at 25 sites, mainly in the central part of the Lewis Range. These older moraines are in places overlain by the Mazama ash. Although the exact age of the moraines has not been determined by radiocarbon dating, vegetative evidence and correlation with other pre-altithermal age moraines in the Rocky Mountains suggest that these older moraines date from 10 000 BP or earlier. Whether these moraines are the product of a separate advance after the end of the Wisconsin glaciation or are simply the product of the last advance or stillstand of Wisconsin glaciers before final deglaciation is not known.Moraines of the younger group, consisting of fresh bouldery rubble, are common throughout Glacier Park. Tree-ring analyses indicate that some of these younger moraines were deposited by advances that culminated during the mid-19th century. At that time there were more than 150 glaciers in Glacier Park. This episode of mid-19th century climatic cooling resulted in the most extensive glacial advance in this region since the end of the Wisconsin glaciation.Present-day glaciers have shrunk drastically from their mid-19th century positions; more than half the glaciers present during that time no longer exist. Much of this retreat occurred between 1920 and the mid-1940's, corresponding to a period of above-average summer temperatures and below-average annual precipitation in this region. Between 1966 and 1979, several of the larger glaciers in the Mount Jackson area of Glacier Park advanced as much as 100 m.</span></p>","language":"English","publisher":"Canadian Science

Analyses of modern log accumulations indicate that unidirectional trunk orientations can be produced by riverflood currents, volcanic blasts, and most high-energy windstorms. Since there are neither fluvial sediments nor ash deposits associated with the Bernice assemblage, this deposit is believed to have been formed by high-energy winds. Furthermore, this deposit is interpreted to be in situ because storm winds (and volcanic blasts) rarely have sufficient energy for the physical transport of large, intact tree trunks. The sedimentary history of the B-coal underclay can be determined from the successional changes in the species and plant part compositions (leaves, seeds, branches, trunks, etc.) of the preserved plant material. The underclay is an accretionary floodplain soil which accumulated as discrete increments during episodic floods. The sediments deposited with each flood incorporated the litter layer of the lycopod-pteridosperm forest which occupied this site. Ordinarily, the flood water would recede, and renewed root growth would destroy the primary sedimentary structures and the newly incorporated organic material. Because the bedding and forest litter are preserved in the top 5 cm of the underclay, root growth and silt deposition must have been terminated by the last flooding event. The site eventually became permanently inundated, and an organic-rich mud began to accumulate in the resulting floodplain lake. The lycopod-pteridosperm forest drowned and, at some later time, was blown down into the lake. The trunks are preserved on a single bedding plane in a 2-cm-thick, organic-rich lacustrine black shale. Continued organic accumulation in the lake resulted in the accumulation of a hypautochthonous peat which eventually was colonized by a peat-forming flora.</p></div></div>","language":"English","publisher":"SEPM","doi":"10.1306/212F8AE9-2B24-11D7-8648000102C1865D","issn":"00224472","usgsCitation":"Wnuk, C., and Pfefferkorn, H., 1987, A Pennsylvanian-age terrestrial storm deposit: using plant fossils to characterize the history and process of sediment accumulation: Journal of Sedimentary Petrology, v. 57, no. 2, p. 212-221, https://doi.org/10.1306/212F8AE9-2B24-11D7-8648000102C1865D.","productDescription":"10 p.","startPage":"212","endPage":"221","numberOfPages":"10","costCenters":[],"links":[{"id":226187,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"57","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e2f4e4b0c8380cd45d54","contributors":{"authors":[{"text":"Wnuk, C.","contributorId":31914,"corporation":false,"usgs":true,"family":"Wnuk","given":"C.","email":"","affiliations":[],"preferred":false,"id":369532,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pfefferkorn, H.W.","contributorId":18910,"corporation":false,"usgs":true,"family":"Pfefferkorn","given":"H.W.","email":"","affiliations":[],"preferred":false,"id":369531,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Although seemingly minor in amount, the total amount of bottom sediment removed from the central and northern California continental shelf by gray whale activities year after year represents macroscale biologically induced erosion and could have significant geological implications in shelf erosion and depositional schemes.

Droughts cause severe water supply problems and water rationing is required, even during periods of normal rainfall. The Laura area contains a substantial lens of fresh groundwater that could be developed for export to the DUD area 30 mi to the east. Study of the groundwater resource at Laura involved a survey of existing wells, installation of monitoring wells and test holes, compilation of continuous records of rainfall and water level fluctuations, and collection of water quality data. Test hole data permitted the definition of three geohydrologic units which correlate well with similar units in Bikini and Enewetak atolls. The units consist of two layers of unconsolidated reef and lagoon sediments resting on a dense, highly permeable limestone. The potable water zone, or freshwater nucleus, of the lens is contained mostly within the unconsolidated layers, which are much less permeable than the basal limestone. Recharge to the Laura freshwater lens is estimated to be 1.8 mil gal/day, based on an average annual rainfall of 140 in. Sustainable yield is estimated to be about 400,000 gal/day. Shallow skimming wells or infiltration galleries similar to those used on Kwajalein atoll would be appropriate to develop the freshwater lens. The impact of development on the lens can be determined by monitoring the salinity in developed water and in a network of monitor wells.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri874047","usgsCitation":"Hamlin, S.N., and Anthony, S.S., 1987, Ground-water resources of the Laura area, Majuro Atoll, Marshall Islands: U.S. Geological Survey Water-Resources Investigations Report 87-4047, vi, 69 p., https://doi.org/10.3133/wri874047.","productDescription":"vi, 69 p.","costCenters":[],"links":[{"id":415606,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_49216.htm","linkFileType":{"id":5,"text":"html"}},{"id":56338,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1987/4047/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":124185,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1987/4047/report-thumb.jpg"}],"country":"Republic of the Marshall Islands","otherGeospatial":"Laura area, Majuro Atoll","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              171.045,\n              7.1667\n            ],\n            [\n              171.023,\n              7.1667\n            ],\n            [\n              171.023,\n              7.133\n            ],\n            [\n              171.045,\n              7.133\n            ],\n            [\n              171.045,\n              7.1667\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a96e4b07f02db65a80d","contributors":{"authors":[{"text":"Hamlin, S.

The upper 150 ft of sedimentary deposits in the inner valley, mostly alluvium that consists of cobbles, gravel, sand, silt, and clay, was emphasized because of its susceptibility to contamination. A map of the water table on February 28, 1986 shows that flow generally is parallel to the river and the gradient is approximately 5 ft/mi or 0.0001. In areas affected by municipal and industrial groundwater withdrawals, declines may exceed 10 ft, and the water table gradient is as much as 20 ft/mi or 0.004. The gradient also is steeper near drains, particularly during the irrigation season. In the area east of the community of Mountainview the direction of water movement may have reversed between 1936 and 1986; flow near appears to be toward the east or southeast. Groups of four piezometers, each screened at a different depth, were monitored to describe seasonal changes of the water table. Vertical gradients between piezometers ranged from 0.014 upward to 0.047 downward from July 1985 to June 1986, but were downward most of the year, particulary during the irrigation season. The horizontal hydraulic conductivity of a 15-ft-thick clay and silt bed beneath Rio Bravo Boulevard is estimated to be 0.0001 ft/day. The average interstitial velocity down through this bed is estimated to range from about 0.0002 to 0.0005 ft/day. The fluctuations of the water table at the piezometers nearest the Rio Grande do not appear to be affected by the riverside drain.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri874015","usgsCitation":"Peter, K.D., 1987, Ground-water flow and shallow-aquifer properties in the Rio Grande inner valley south of Albuquerque, Bernalillo County, New Mexico: U.S. Geological Survey Water-Resources Investigations Report 87-4015, iv, 29 p., https://doi.org/10.3133/wri874015.","productDescription":"iv, 29 p.","costCenters":[],"links":[{"id":57994,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1987/4015/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123690,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1987/4015/report-thumb.jpg"},{"id":415599,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_46703.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"New Mexico","county":"Bernalillo County","city":"Albuquerque","otherGeospatial":"Rio Grande Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -106.5833,\n              35.095\n            ],\n            [\n              -106.7292,\n              35.095\n            ],\n            [\n              -106.7292,\n              34.9394\n            ],\n            [\n              -106.5833,\n              34.9394\n            ],\n            [\n              -106.5833,\n              35.095\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66cd65","contributors":{"authors":[{"text":"Peter, K.

The model consists of a series of 80 spherical harmonics, up to and including those of degree and order 8. We used it to form a proposal for the 1985 revision of the International Geomagnetic Reference Field (IGRF). Comparison of the new model, whose mean epoch is approximately 1982.0, with the Provisional Geomagnetic Reference Field for 1975-1980 (PGRF 1975), indicates that the moment of the centered-dipole part of the geomagnetic field is now decreasing faster than it was 5 years ago. The rate (in field units) indicated by PGRF 1975 was about -25 nT a-1, while for the new model it is -28 nT a-1. ?? 1987.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Physics of the Earth and Planetary Interiors","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0031-9201(87)90155-5","issn":"00319201","usgsCitation":"Peddie, N., and Zunde, A., 1987, A model of geomagnetic secular variation for 1980-1983: Physics of the Earth and Planetary Interiors, v. 48, no. 3-4, p. 324-329, https://doi.org/10.1016/0031-9201(87)90155-5.","startPage":"324","endPage":"329","numberOfPages":"6","costCenters":[],"links":[{"id":267331,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0031-9201(87)90155-5"},{"id":225428,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"48","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e47fe4b0c8380cd46681","contributors":{"authors":[{"text":"Peddie, N.W.","contributorId":75911,"corporation":false,"usgs":true,"family":"Peddie","given":"N.W.","affiliations":[],"preferred":false,"id":367790,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zunde, A.K.","contributorId":21946,"corporation":false,"usgs":true,"family":"Zunde","given":"A.K.","affiliations":[],"preferred":false,"id":367789,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The stagnation in the coal industry east of the Mississippi is alleged to have been caused by this declining productivity and by the growth of cheaper and cleaner coal production west of the Mississippi. Economic evidence suggests, however, that productivity declines were more due to a relative lowering of labor costs in comparison with coal prices and due to work stoppages. The development of western coals fields was spurred by growth in local demand and had only a relatively small impact on coal production east of the Mississippi. Problems of the eastern coal industry are rooted mainly in slow economic growth in eastern U.S. which must be addressed in the long-term interests of the eastern coal industry.</p></div></div></div></div><div id=\"preview-section-introduction\"><br></div><div id=\"preview-section-snippets\"><br></div><div id=\"preview-section-references\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0166-5162(87)90073-5","issn":"01665162","usgsCitation":"Bhagwat, S., 1987, Economics of the coal industry east of the Mississippi, 1973-1982: International Journal of Coal Geology, v. 8, no. 4, p. 367-373, https://doi.org/10.1016/0166-5162(87)90073-5.","productDescription":"7 p.","startPage":"367","endPage":"373","numberOfPages":"7","costCenters":[],"links":[{"id":225945,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0591e4b0c8380cd50e4f","contributors":{"authors":[{"text":"Bhagwat, S.B.","contributorId":58025,"corporation":false,"usgs":true,"family":"Bhagwat","given":"S.B.","email":"","affiliations":[],"preferred":false,"id":367876,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
