www.absc.usgs.gov — The North Pacific Pelagic Seabird Database is an ongoing project between the USGS and Fish and Wildlife Service that addresses data on the pelagic distribution and abundance of seabirds. This project has collected data from researchers in Canada, Russia, and the U.S. (1972-2003). This information is critical for understanding the basic ecology of More...

soundwaves.usgs.gov — Kristen Hart and Keith Ludwig of the USGS Florida Integrated Science Center (FISC) participated in two research cruises in 2008 to study patterns of habitat use by endangered sea turtles in and around the National Park. Hart's research effort focuses on quantifying patterns of sea turtle habitat use, employing capture-recapture and satellite- and More...

www.climatescience.gov — The U.S. Environmental Protection Agency has released a report that can help reduce the potential impact of climate change on estuaries, forests, wetlands, coral reefs, and other sensitive ecosystems. The report identifies strategies to protect the environment as these changes occur. The report finds that climate change can increase the impact of More...

soundwaves.usgs.gov — U.S. Geological Survey (USGS)'s Western Region held an internal USGS workshop on Sea-Level-Rise Impacts on November 6-7, 2007, in Menlo Park, California. The meeting was attended by 30 scientists from four USGS disciplines (geology, geography, biology, and water) and 13 different science centers in the Western Region. In part a follow-up to the More...

www.werc.usgs.gov — Mercury is a contaminant of significant concern in waterbirds because it can accumulate to high concentrations in their tissues and cause deleterious effects such as impaired reproduction. Numerous studies and monitoring programs have evaluated concentrations of mercury in waterbird tissues as an index of risk to exposure. However, no single More...

www.werc.usgs.gov — Sea otters (Enhydra lutris) are keystone predators in the nearshore environment of the eastern Pacific Ocean, in a food web composed of sea otter, sea urchin, and kelp forest. Without sea otters, the kelp forest can be overgrazed by sea urchins, which in turn can affect other species that depend on this ecosystem. This resource provides links to More...

alaska.usgs.gov — This study is a new analytical procedure that quantifies the degree of overlap between adjacent populations of polar bears, and provides science for better management of the harvest of polar bears in the Beaufort and Chukchi Seas. This new analytical approach allows previously accepted population management units to be subdivided in ways that will More...

wfrc.usgs.gov — Over the past 150 years, land reclamation activities have resulted in loss of significant amounts of tidal marshes (sometimes referred to as inter-tidal wetlands, the estuarine zone that is alternately flooded and exposed) in San Francisco Bay and the Sacramento-San Joaquin Delta (Bay/Delta). Recently, in an effort to halt or reverse the decline More...
