This is a first cut at a statewide 1:63,360 coastline. The entire coasline, however, is not 1:63.360; only where data was available as of January 1998. It is a mixture of sources ranging from the Department of Natural Resources, Land Records Information Section hydrography database to the Exxon Valdez Oil Spill Environmentally Sensitive Index coastline (no ESI attributes included) to the US Geologic Survey hydrography to US Forest Service (in Prince William Sound). Where the 1:63,360 data was unavailable the 1:250,000 coastline was used to fill in. This information does not include lakes or streams. All streams are cut off at the mouth with a straight line. It excludes small islands that are difficult to visually...

Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified...

This dataset provides an estimate of current terrestrial intactness, based on a fuzzy logic model that integrates multiple measures of landscape development and vegetation intactness. A powerpoint version of the logic model is available at: Vector\Conservation_Elements\Terrestrial\Ecosystem\Documentation\SOD_TI_logic_models.pptx This model integrates agriculture development (from LANDFIRE EVT v1.1), urban development (from LANDFIRE EVT v1.1 and NLCD Impervious Surfaces), linear development (from BLM GTLF, utility lines, and pipelines), energy and mining development (from state mine and USGS national mines datasets, geothermal wells, and oil/gas wells), invasive vegetation (multiple sources combined for invasives...

This dataset presents the current potential distribution of lowland leopard frog in the context of current and near-term aquatic intactness, and long-term potential for climate change at the watershed (HUC5) scale. Current aquatic intactness is based on current measures of landscape development, water quality, hydrologic impacts, and road impacts. Near-term intactness includes estimates of urban growth. Long-term potential for climate change is based on absolute changes in runoff, precipitation, temperature, and vegetation change estimated using climate projections (RegCM3 regional climate model based on ECHAM5 boundary conditions) and a biogeography model (MAPSS) for the period 2045-2060. The aquatic intactness...

This report, released by the Energy andBiodiversity Initiative (EBI), is the resultof a collaborative effort by representa-tives of the nine member companiesand conservation organizations of theInitiative. The views expressed hereindo not necessarily represent the viewsof every EBI member.EBI members recognize that there is a continuing public debate aroundbiodiversity conservation and oil andgas operations. Although EBI was notintended to resolve all the issues in-volved in this debate, we believe theEBI products and process will make a significant contribution to con-structive dialogue to accompany thatdebate. We welcome your commentsand feedback on this document or any other EBI products.
High-angle, open mode fractures control the presence of natural gas hydrate in water-saturated clays at the Keathley Canyon 151 site in the northern Gulf of Mexico, which was investigated for gas hydrates as part of the Chevron Joint Industry Project drilling in 2005. We analyze logging-while-drilling resistivity images and infer that gas hydrate accumulated in situ in two modes: filling fractures and saturating permeable beds. High-angle hydrate-filled fractures are the most common mode for gas hydrate occurrence at this site, with most of these fractures dipping at angles of more than 40° and occurring between 220 and 300 m below seafloor. These fractures all strike approximately N-S, which agrees with the 165°SE-345°NW...
