Variation in geologic substrate, landforms, and soils, in combination with steep environmental gradients, create habitat diversity across spatial scales from 10<sup>6</sup> ha to &lt;10 m<sup>2</sup>. This leads to higher biodiversity in a smaller space than in landscapes with less topographic variation. Mountains are often considered to be refuges for biological diversity at the regional scale, although variation in landscape features creates refuges at a fine scale as well. Mountains should also be considered a source of biological diversity, because they provide the germplasm for migration into lowland areas following glacial recession. Many taxa are distributed over a broad range of elevations and habitats, which maximizes the potential to respond to environmental perturbations. Reorganization of species distribution and abundance as a result of climatic change may be impacted considerably by human-caused fragmentation of landscape features, especially at lower elevations. This paper uses palaeoecological and biogeographical data to investigate the spatial and temporal vegetation dynamics of a steep maritime range, the Olympic Mountains (USA).

We investigated a large data set of BHT and DST measurements taken in boreholes in the American Midcontinent, a geologically uniform stable cratonic area, and propose an empirical correction for BHTs based on relationships between BHTs, DSTs, and thermal logs. This empirical correction is compared with similar approaches determined for other areas. The data were analyzed by multivariate statistics prior to the BHT correction to identify anomalous measurements and quantify external influences. Spatial patterns in temperature measurements for major stratigraphic units outline relations to regional structure. Comparision of temperature and structure trend-surface residuals reveals a relationship between temperature highs and local structure highs. The anticlines, developed by continuous but intermittent movement of basement fault blocks in the Late Paleozoic, are subtle features having closures of 10-30 m and contain relatively small hydrocarbon reservoirs.

In many cases, state or federal agencies have a unique opportunity to condition the hydropower licenses to protect environmental values. In 1996, the Court of Appeals for the District of Columbia Circuit issued an opinion striking down a mandatory license condition imposed by the U.S. Department of the Interior in a FERC relicensing. The case, Bangor Hydro-Electric Company v.Federal Energy Regulatory Commission, is instructive for agencies regarding the procedures to be followed in imposing mandatory FERC licensing conditions in the future. After Bangor Hydro, agencies should: (1) support their decisions by substantial evidence in the FERC record, (2) request applicant studies to support agency decisions and allow public comment on the decisions as a means to test the facts and analysis, and (3) consider intervening in a case to defend the condition on appeal. Bangor Hydro also raises, but does not decide, the issue of whether the agency imposing the mandatory condition should engage in balancing the economics of the hydropower project with the public resources affected by the project.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Rivers","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"08988048","usgsCitation":"Pizzi, L., 1997, Implications of the Bangor Hydro decision on FERC relicensings: Rivers, v. 6, no. 2, p. 103-115.","startPage":"103","endPage":"115","numberOfPages":"13","costCenters":[],"links":[{"id":226365,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a392ce4b0c8380cd61822","contributors":{"authors":[{"text":"Pizzi, L.","contributorId":19307,"corporation":false,"usgs":true,"family":"Pizzi","given":"L.","affiliations":[],"preferred":false,"id":381789,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Here we compile the most current laboratory-derived flow laws for water ice phases I, II, III, V, and VI, and ice I mixtures with hard particulates. The rheology of interest is mainly that of steady state, and the conditions reviewed are the pressures and temperatures applicable to the surfaces and interiors of icy moons of the outer solar system. Advances in grain-size-dependent creep in ices I and II as well as in phase transformations and metastability under differential stress are also included in this compilation. At laboratory strain rates the several ice polymorphs are rheologically distinct in terms of their stress, temperature, and pressure dependencies but, with the exception of ice III, have fairly similar strengths. Hard particulates strengthen ice I significantly only at high particulate volume fractions. Ice III has the potential for significantly affecting mantle dynamics because it is much weaker than the other polymorphs and its region of stability, which may extend metastably well into what is nominally the ice II field, is located near likely geotherms of large icy moons.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/97JE00916","issn":"01480227","usgsCitation":"Durham, W., Kirby, S.H., and Stern, L., 1997, Creep of water ices at planetary conditions: A compilation: Journal of Geophysical Research E: Planets, v. 102, no.

This event is typically recognized by a distinctive physical surface and/or a significant change in microfossil assemblages (relative fossil abundance peaks) in siliciclastic deposits from shoreline to continental slope environments in a passive margin setting. Recognition of maximum flooding events in mixed siliciclastic-carbonate sediments is more complicated because the entire section usually represents deposition in continental shelf environments with varying rates of biologic and carbonate productivity versus siliciclastic influx. Hence, this event cannot be consistently identified simply by relative fossil abundance peaks. Factors such as siliciclastic input, carbonate productivity, sediment accumulation rates, and paleoenvironmental conditions dramatically affect the relative abundances of microfossils. Failure to recognize these complications can lead to a sequence stratigraphic interpretation that substantially overestimates the number of depositional sequences of 1 to 10 m.y. duration.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1997)025<0351:ROMFEI>2.3.CO;2","issn":"00917613","usgsCitation":"Mancini, E.A., and Tew, B., 1997, Recognition of maximum flooding events in mixed siliciclastic-carbonate systems: Key to global chronostratigraphic correlation: Geology, v. 25, no. 4, p. 351-354, https://doi.org/10.1130/0091-7613(1997)025<0351:ROMFEI>2.3.CO;2.","productDescription":"4 p.","startPage":"351","endPage":"354","numberOfPages":"4","costCenters":[],"links":[{"id":226821,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9678e4b0c8380cd81ff4","contributors":{"authors":[{"text":"Mancini, E.

Faults that break the sea floor show evidence of both extension and shortening; mud diapirs are also present. The zone of recent faulting apparently extends from the ocean floor down to the base of gas-hydrate stability. We infer that the faulting resulted from excess pore pressure in gas trapped beneath the gas hydrate-beating layer and/or weakening and mobilization of sediments in the region just below the gas-hydrate stability zone. In addition to the zone of surface faults, we identified two buried zones of faulting, that may have similar origins.

Surface waves associated with winter storm winds from the northeast cause large sediment resuspension events, and wave and circulation fields during these events have a quasi-steady response to the wind stress. Coupled wave, circulation, and boundary layer models indicate that wave-enhanced bottom friction has a significant damping effect on storm-driven circulation in Massachusetts Bay. The simulated response exhibits significant three-dimensional structure, but still can be fundamentally understood using idealized models. The depth-integrated momentum balance is dominated by along-bay stress, pressure gradient, and bottom stress. The effective bottom drag coefficient during typical storm conditions is increased by a factor of 2-5 when wave effects are included, but the mean bottom stress is relatively unaffected by wave effects due to a reduction in bottom currents by 30-50%. The vertical mixing is also relatively unaffected by the waves, and the result is that the increased drag causes a nearly depth-independent offset of the vertical current profiles. The alongshore transport in the bay is reduced 10-50%, depending on wind direction.&nbsp;</p>","language":"English","publisher":"American Society of Civil Engineers","doi":"10.1061/(ASCE)0733-950X(1997)123:5(233)","issn":"0733950X","usgsCitation":"Signell, R.P., and List, J.H., 1997, Effect of wave-enhanced bottom friction on storm-driven circulation in Massachusetts Bay: Journal of Waterway, Port, Coastal and Ocean Engineering, v. 123, no. 5, p. 233-239, https://doi.org/10.1061/(ASCE)0733-950X(1997)123:5(233).","productDescription":"7 p.","startPage":"233","endPage":"239","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":226628,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Cape Cod Bay, Massachussetts Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -71.4111328125,\n              41.40153558289846\n            ],\n            [\n              -69.78515625,\n              41.40153558289846\n            ],\n            [\n              -69.78515625,\n              42.98857645832184\n            ],\n            [\n              -71.4111328125,\n              42.98857645832184\n            ],\n            [\n              -71.4111328125,\n              41.40153558289846\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"123","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a062ee4b0c8380cd51133","contributors":{"authors":[{"text":"Signell, R.

New U-Pb radiometric dating indicates that the development of a northward-trending lineation in the infrastructure is partly coeval with the development of a pervasive, west-northwest–trending lineation in the mylonitic shear zone. U-Pb monazite data from the leucogranite orthogneiss of Thorpe Creek indicate a crystallization age of ca. 36–39 Ma. Zircon fractions from a biotite monzogranite dike yield an age of ca. 29 Ma. The three dated samples from these units exhibit a penetrative, approximately north-south–trending elongation lineation. This lineation is commonly defined by oriented bundles of sillimanite and/or elongated aggregates of quartz and feldspar, indicating a synmetamorphic and syndeformational origin. The elongation lineation can be interpreted as a slip line in the flow plane of the migmatitic, nonmylonitic infrastructural core of the northern Ruby Mountains. A portion of this midcrustal flow is coeval with the well-documented, west-northwest sense of slip in the structurally overlying kilometer-thick, mid-Tertiary mylonitic shear zone. Lineations in the mylonitic zone are orthogonal to those in the deeper infrastructure, suggesting fundamental plastic decoupling between structural levels in this core complex. Furthermore, the infrastructure is characterized by overlapping, oppositely verging fold nappes, which are rooted to the east and west. One of the nappes may be synkinematic with the intrusion of the late Eocene orthogneiss of Thorpe Creek.

Previous studies have tested the effects of structural management on aboveground biomass after implementing management, but very few studies have collected data before and after management. Thus, to test the effects of structural marsh management on Spartina patens (Ait.) Muhl. and Scirpus americanus Pers., the aboveground biomass of both species was estimated before and after the construction of shallow, leveed impoundments. The water level in each impoundment was managed with a single flap-gated culvert fitted with a variable crest weir. Additionally, the influence of nutria grazing on aboveground biomass was measured by nondestructively sampling fenced (ungrazed) and unfenced (grazed) plots in both managed and unmanaged areas. While there was no significant difference in S. patens production between managed and unmanaged areas, marsh management negatively affected Sc. americanus production the two species also differed in their responses to grazing. Grazing dramatically reduced the sedge, Sc. americanus, while the grass, S. patens, remained at similar biomass levels in grazed and ungrazed plant stands. These findings support the belief that herbivory has a strong influence on plant production, but do not support the claim that management increases plant production in the deltaic marshes of Louisiana.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Aquatic Botany","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0304-3770(97)00031-4","issn":"03043770","usgsCitation":"Johnson, L., and Foote, A., 1997, Vertebrate herbivory in managed coastal wetlands: A manipulative experiment: Aquatic Botany, v. 59, no. 1-2, p. 17-32, https://doi.org/10.1016/S0304-3770(97)00031-4.","startPage":"17","endPage":"32","numberOfPages":"16","costCenters":[],"links":[{"id":205764,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0304-3770(97)00031-4"},{"id":226629,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"59","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc22be4b08c986b32a982","contributors":{"authors":[{"text":"Johnson, L.A.","contributorId":8237,"corporation":false,"usgs":true,"family":"Johnson","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":381701,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Foote, A.L.","contributorId":66435,"corporation":false,"usgs":true,"family":"Foote","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":381702,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, direct summation of environmental data is not generally feasible because it is common for some chemical concentrations to be recorded as being below the analytical reporting limit. This creates special problems in the analysis of the data. A new model selection procedure, named forward censored regression, is introduced for selecting an appropriate model for environmental data with censored observations. The procedure is demonstrated using concentrations of atrazine (2-chloro-4-ethylamino-6-isopropylamino-</span><i>s</i><span>-triazine), deethylatrazine (DEA, 2-amino-4-chloro-6-isopropylamino-</span><i>s</i><span>-triazine), and deisopropylatrazine (DIA, 2-amino-4-chloro-6-ethylamino-</span><i>s</i><span>-triazine) in groundwater in the midwestern United States by using the data derived from a previous study conducted by the U.S. Geological Survey. More than 80% of the observations for each compound for this study were left censored at 0.05 &mu;g/L. The values for censored observations of atrazine, DEA, and DIA are imputed with the selected models. The summation of atrazine residue (atrazine + DEA + DIA) can then be calculated using the combination of observed and imputed values to generate a pseudo-complete data set. The all-subsets regression procedure is applied to the pseudo-complete data to select the final model for atrazine residue. The methodology presented can be used to analyze similar cases of environmental contamination involving censored data.</span></p>","language":"English","publisher":"ACS","doi":"10.1021/es960695x","issn":"0013936X","usgsCitation":"Liu, S., Lu, J., Kolpin, D., and Meeker, W., 1997, Analysis of environmental data

A study of tree growth was initiated at Caddo Lake to address concerns about the health of the baldcypress ecosystem. The lake has been subjected to several dramatic water-level changes over the past 200 years, including water-level stabilization following dam construction in 1914. To assess the long-term growth trends of baldcypress trees and determine if a recent growth decline is occurring at Caddo Lake, increment cores were taken from 52 trees. The cores were crossdated and rings between the years 1900 and 1992 measured to the nearest 0.01 mm. Most cores were characterized by high variation in year-to-year growth. Although increasing growth rates were observed at most locations, trees from two backwater areas of the lake had recent growth rates lower than their long-term average. Growth amounts at these two sites were, however, within the historic range of variation. No recruitment was observed. From these data, we can conclude that the historic, extreme changes in hydrologic regime and the current stabilized water levels have not resulted in an overall decline in baldcypress growth at Caddo Lake.","language":"English","publisher":"Springer","doi":"10.1007/BF03161522","issn":"02775212","usgsCitation":"Keeland, B.D., and Young, P., 1997, Long-term growth trends of baldcypress (Taxodium distichum (L.) rich.) at Caddo Lake, Texas: Wetlands, v. 17, no. 4, p. 559-566, https://doi.org/10.1007/BF03161522.","productDescription":"8 p.","startPage":"559","endPage":"566","numberOfPages":"8","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":226678,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Texas","otherGeospatial":"Caddo Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -94.37667846679688,\n              32.64110949213927\n            ],\n            [\n              -94.04571533203125,\n              32.64110949213927\n            ],\n            [\n              -94.04571533203125,\n              32.895732015669815\n            ],\n            [\n              -94.37667846679688,\n              32.895732015669815\n            ],\n            [\n              -94.37667846679688,\n              32.64110949213927\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"17","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4993e4b0c8380cd68720","contributors":{"authors":[{"text":"Keeland, B.

Specific objectives included assessment of possible agricultural and industrial sources of contamination, especially from airborne effluent emitted by a local power plant. The study also tested the adequacy of a fixed-depth soil sampling procedure developed for meager karstic soils. Although 40 geochemical variables were analyzed, only 15 elements and 5 radionuclides are common to all the sample locations. These elements can be divided into three groups: (1) those of mostly anthropogenic origin — Pb, V, Cu and Cr; (2) those of mixed origin — radionuclides and Zn; and (3) those of mostly geogene origin — Ba, Sr, Ti, Al, Na, Ca, Mg, Fe, Mn, Ni and Co. Variation in Pb shows a strong correlation with the pattern of road traffic in Istria.

Parkfield is near the southern end of the Coast Ranges segment of the San Andreas fault. This segment has higher mean heat flow than the Cape Mendocino segment to the northwest or the Mojave segment to the southeast. Boreholes were drilled specifically for the U.S. Geological Survey's Parkfield earthquake prediction experiment or converted from other uses at 25 sites within a few kilometers of the fault near Parkfield. These holes, which range in depth from 150 to over 1500m, were intended mainly for the deployment of volumetric strain meters, water-level recorders, and other downhole instruments. Temperature profiles were obtained from all the holes, and heat flow values were estimated from 17 of them. For a number of reasons, including a paucity of thermal conductivity data and rugged local topography, the accuracy of individual determinations was not sufficiently high to document local variations in heat flow. Values range from 54 to 92 mW m</span><sup>−2</sup><span>, with mean and 95% confidence limits of 74±4 mW m</span><sup>−2</sup><span>. This mean is slightly lower than the mean (83±3) of 39 previously published values from the central Coast Ranges, but it is consistent with the overall pattern of elevated heat flow in the Coast Ranges, and it is transitional to the mean of 68±2 mW m</span><sup>−2</sup><span>&nbsp;that characterizes the Mojave segment of the San Andreas fault immediately to the south. The lack of a heat flow peak near the fault underscores the absence of a frictional thermal anomaly and provides additional support for a very small resolved shear stress parallel to the San Andreas fault and the nearly fault-normal maximum compressive stress observed in this region. Estimates of subsurface thermal conditions indicate that the seismicaseismic transition for the Parkfield segment corresponds to temperatures in the range of 350°–400°C. Increasing heat flow to the northwest of Parkfield corresponds to a transition from locked to creeping sections and to a shallowing of the base of seismicity and confirms the importance of temperature in controlling the thickness of the seismogenic crust.

Surficial sediment samples from gravity cores, deeper samples (as much as 390 m) from Site 35 of the Deep Sea Drilling Program (Leg 5), and the acoustic character of the sediment fill observed on seismic-reflection profiles indicate that much of the sediment fill is of turbidite origin. Gross composition and heavy- mineral analyses of sand samples show that two distinct petrofacies comprise the sediment fill. The lower part of the fill was derived primarily from the Klamath River source of northern California while the younger fill, including the surficial sand beds, are from the Columbia River drainage much farther north. The Escanaba Trough sediment provides an opportunity to evaluate concepts for paleogeographic and paleotectonic reconstructions that are based on facies analysis and compositional and textural data for the volcanic components because both intrabasinal and extrabasinal sources are present as well as coeval (neovolcanic) and non coeval (paleovolcanic) sourcre This study of a modern basin shows, that although the sediment sources could be identified, it was useful to have some knowledge of the sediment pathway(s), the effects of diagenesis, and the possible effects of sediment sorting as a result of long transport distances from the source area for some components.

Using an integrated approach that included the use of analytical modeling, numerical modeling, and data analysis, we have found that there are substantial contributions to the total budgets of heat over the BOREAS domain generated by mesoscale circulations. This effect is largest when the synoptic flow is relatively weak, yet it is present under less favorable conditions, as shown by the case study presented here. While further analysis is warranted to document this effect, the existence of mesoscale flow is not surprising, since it is related to the presence of landscape patches, including lakes, which are of a size on the order of the local Rossby radius and which have spatial differences in maximum sensible heat flux of about 300 W m-2. We have also analyzed the vertical temperature profile simulated in our case study as well as high-resolution soundings and we have found vertical profiles of temperature change above the boundary layer height, which we attribute in part to mesoscale contributions. Our conclusion is that in regions with organized landscapes, such as BOREAS, even with relatively strong synoptic winds, dynamical scaling criteria should be used to assess whether mesoscale effects should be parameterized or explicitly resolved in numerical models of the atmosphere.","language":"English","publisher":"AGU","doi":"10.1029/97JD02561","issn":"01480227","usgsCitation":"Vidale, P., Pielke, R., Steyaert, L.T., and Barr, A., 1997, Case study modeling of turbulent and mesoscale fluxes over the BOREAS region: Journal of Geophysical Research D: Atmospheres, v. 102, no. 24, p. 29167-29188, https://doi.org/10.1029/97JD02561.","productDescription":"22 p.","startPage":"29167","endPage":"29188","numberOfPages":"22","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":479966,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/97jd02561","text":"Publisher Index Page"},{"id":226281,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"102","issue":"24","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f38be4b0c8380cd4b887","contributors":{"authors":[{"text":"Vidale, P.L.","contributorId":35690,"corporation":false,"usgs":true,"family":"Vidale","given":"P.L.","email":"","affiliations":[],"preferred":false,"id":381900,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pielke, R.A.
