Summary

Several bureaus within the Department of Interior compiled available information from seabird observation datasets from the Atlantic Outer Continental Shelf into a single database, with the goal of conducting research and informing coastal and offshore planning activities. The cooperators were the Bureau of Ocean Energy Management's (BOEM) Environmental Studies Program (http://www.boem.gov/Environmental-Stewardship/Environmental-Studies/Environmental-Studies.aspx), the U.S. Fish and Wildlife Service's (USFWS) Division of Migratory Bird Management (http://www.fws.gov/migratorybirds/) and the U.S. Geological Survey's (USGS) Patuxent Wildlife Research Center (http://www.pwrc.usgs.gov). The resulting product is the Atlantic Offshore Seabird [...]

Purpose

As of December 2013, the database holds over 70 datasets from 1906-2009 with over 300,000 records of seabird observations. Summary maps provided as web services (see linkage) include representations of survey effort and bird detections. Effort was standardized into "five minute equivalents" so that both discrete and continuous transect data could be combined. This unit is essentially "five minutes of survey effort from a vessel traveling 10 knots". Species data were prepared for occurrence maps by adjusting counts using these five minute equivalents. The resulting species maps are referred to as "Naive occurrence maps" because, although some effort standardization has been applied, there are no corrections for biases introduced by differences in survey methodology, observers, and species detectability.The full archive of scientific data is available for download from the National Oceanographic and Atmospheric Administration (NOAA) National Oceanographic Data Center (NODC) contains information on individual observations as well as survey effort. Each observation record has a unique point location, date and time, species and observation count. There may also be biological information related to the sighting, such as animal age or behavior. The survey effort information (i.e. weather variables) may have been recorded for each individual observation but was more often recorded at the transect (line along which the plane or boat traveled) level. The dataset contains data primarily for seabirds, but some other observations accompanied bird data submissions and were not discarded: marine mammals, turtles, fish, and non-biological sightings such as other boats, fishing gear and trash.
