NOAA National Centers for Environmental Information author Larsen, Kirsten NOAA National Centers for Environmental Information author Sallis, David NOAA National Centers for Environmental Information author NOAA National Centers for Environmental Information author NOAA Fisheries Sea Turtle Stranding and Salvage Network author tableDigital This dataset contains the sea turtle beaching probability index (BPI) for the northern Gulf of America region since 2017-01-01. The data files are in CSV and JPEG formats. The daily CSV files contain beaching probability indexes with latitudes, longitudes, total accumulations, and stranding density log scaled radii (for plotting). The yearly CSV files contain daily accumulated BPI for the nine predefined regions. The daily JPEG files are BPI spatial distribution plots for these regions. The BPI describes the likelihood that dead or debilitated sea turtles floating at the sea surface will be deposited on shore based on prevailing wind and currents. BPI is an indicator of favorable beaching conditions, that is, if there are drifting carcasses, they will be more likely to beach if BPI is high. This relationship between strandings and environmental conditions is relevant to understanding causes of stranding as well as the degree to which at-sea mortality may be represented by animals found on shore. The BPI applies velocity and direction of surface currents and wind from the American Seas Ocean Model (AMSEAS) of the Regional Navy Coastal Ocean Model (NCOM) to predict and describe the probability that floating turtles will be brought into shore. Within the BPI simulation, surface currents and winds from AMSEAS were used to push particles for an 8 day period based on lab and field studies of decomposition and persistence of sea turtle carcasses in the environment. Each day, at 0 h GMT, new particles were seeded onto a starting grid of 84,044 points spaced 1 nautical mile apart. This uniform grid extended from the coast to 60 nautical miles offshore, which is the furthest distance sea turtle carcasses were likely to drift based on observations. The system maintained a running tally such that on any given day all objects that are still in motion and less than 8 days old were pushed forward. Particles that encountered shallow water (<25 cm depth) stopped moving and were counted as "beached". The leeway value, the amount of "push" the wind gives a floating object was set to 3.5%, a value applicable to sea turtles or any other floating object which has about 50% of its area exposed above the sea surface. This dataset is available to the public for a wide variety of uses including scientific research and analysis. onGoing historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact monthly https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:NCEI-Sea-Turtle-GOA-BPI Preview graphic PNG 0270549 0272594 0273418 0273518 0273519 0274432 0276211 0286764 0300299 0311279 NCEI ACCESSION NUMBER 2026-07-14 publication sea turtles theme NODC DATA TYPES THESAURUS model output theme NODC OBSERVATION TYPES THESAURUS NOAA National Centers for Environmental Information dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Deepwater Horizon oil spill event (DWH) project NODC PROJECT NAMES THESAURUS Coastal Waters of Gulf of America Coastal Waters of Gulf of Mexico Gulf of America Gulf of Mexico place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
