The GIS shapefile "Census summary of southern sea otter 2016" provides a standardized tool for examining spatial patterns in abundance and demographic trends of the southern sea otter (Enhydra lutris nereis), based on data collected during the spring 2016 range-wide census. The USGS range-wide sea otter census has been undertaken twice a year since 1982, once in May and once in October, using consistent methodology involving both ground-based and aerial-based counts. The spring census is considered more accurate than the fall count, and provides the primary basis for gauging population trends by State and Federal management agencies. This Shape file includes a series of summary statistics derived from the raw census...

The GIS shapfile "Range extent of southern sea otter 2016" is a simple polyline representing the geographic distribution of the southern sea otter (Enhydra lutris nereis) in mainland California, based on data collected during the spring 2016 range-wide census. The USGS range-wide sea otter census has been undertaken twice a year since 1982, once in May and once in October, using consistent methodology involving both ground-based and aerial-based counts. The spring census is considered more accurate than the fall count, and provides the primary basis for gauging population trends by State and Federal management agencies. Sea otter distribution in California (the mainland range) is considered to comprise a band of...

The GIS layer "Census_sum_15" provides a standardized tool for examining spatial patterns in abundance and demographic trends of the southern sea otter (Enhydra lutris nereis), based on data collected during the spring 2015 range-wide census. The USGS range-wide sea otter census has been undertaken twice a year since 1982, once in May and once in October, using consistent methodology involving both ground-based and aerial-based counts. The spring census is considered more accurate than the fall count, and provides the primary basis for gauging population trends by State and Federal management agencies. This Shape file includes a series of summary statistics derived from the raw census data, including sea otter density...

Recent interest has increased related to developing alternative sources of renewable energy to reduce dependence on oil. Some of those sources will include power generation infrastructure and support activities located within continental shelf waters, and potentially within deeper waters off the U.S. Pacific coast and beyond state waters (i.e., outside three nautical miles). Currently, the Bureau of Ocean Energy Management (BOEM) is considering renewable energy proposals off the coast of Oregon. The 2011-2012 Pacific Continental Shelf Environmental Assessment (PaCSEA) project is intended to provide new information on species composition, distribution, abundance, seasonal variation, and habitat utilization among...

This data product was created for the project titled: “Application of the Coastal and Marine Ecological Classification Standard (CMECS) to the Northwest Atlantic” which was partially funded by the U.S. Department of the Interior, Fish and Wildlife Service and a joint collaborative project with The Nature Conservancy (Eastern Division Conservation Science), University of Rhode Island (Graduate School of Oceanography), and Massachusetts Department of Fish and Game (Division of Marine Fisheries). In the Northeast United States region, efforts are underway to better organize and integrate spatial marine data to support ocean planning and management efforts. An important step in this process is translating existing...
