Companion

Companion map layers automatically activate when users select a species from the Avian datasets in the Marine Life Library (Species Specific). The zones covered by grey lines denote areas of low survey effort. NOTE: Because the Marine Life Library data is input from an external source, all of its maps are "session-based" (deactivated once a user leaves or refreshes the page) and cannot be linked to via the headings below, bookmarks or the Portal's URL generator. Users should instead visit http://seamap.env.duke.edu/models/mdat/ for a report with a full explanation of this data. The site also includes downloadable map data products, metadata and other information related to the work of a Marine Life Data and Analysis Team (MDAT) that developed the Portal's Marine Life Library.

Unsurveyed area (avian, annual)

Area with no Annual survey effort in the dataset analyzed by NOAA NCCOS (Winship et al. 2018). Data analyzed were from the Northwest Atlantic Seabird Catalog (US Fish and Wildlife Service; April 2017) and Eastern Canada Seabirds at Sea database (Canadian Wildlife Service, Environment and Climate Change Canada; February 2017). Mid-points of survey transect segments (~4 km in length) were gridded at a 10 x 10 km resolution, and hatched areas indicate grid cells with no segment mid-points.
