NCCOS Assessment: Modeling At-Sea Density of Marine Birds to Support Atlantic Marine Renewable Energy Planning from 1978-2016 (NCEI Accession 0176682)
This dataset provides seasonal spatial rasters of median predicted long-term (1978-2016) relative density of 47 marine bird species throughout the US Atlantic Outer Continental Shelf (OCS) and adjacent waters at a 2-km spatial resolution. Three indications of the uncertainty associated with the model predictions are also provided: 1) seasonal spatial layers indicating areas with no survey effort, 2) seasonal spatial rasters of the precision of predicted relative density of each species characterized as its coefficient of variation (CV), and 3) seasonal spatial rasters of the precision of predicted relative density of each species characterized as its 90% confidence interval. Predicted relative density should always be considered in conjunction with these three indications of uncertainty. Suggested symbology class breaks and labels for mapping predicted relative density and its CV are also included. Finally, this dataset also includes spatial rasters of environmental predictor variables that were used in the predictive modeling.

Supplemental Information | This analysis relied mainly on two types of data: counts of marine birds at sea from sighting surveys and information about the U.S. Atlantic OCS environment. Sighting datasets were provided by USGS and USFWS (Northwest Atlantic Seabird Catalog) and by CWS-ECCC (ECSAS database). Available spatial information describing the environment of U.S. Atlantic OCS and adjacent waters was compiled and synthesized by NCCOS. Environmental data came from a range of sources including remote sensing datasets and an ocean model dataset. Spatial environmental variables were characterized as spatial rasters, with dynamic variables represented by seasonal long-term climatologies. Spatial predictive modeling was applied to the sighting data to account for spatial and temporal heterogeneity in survey effort, platform, and protocol. An ensemble machine-learning technique, component-wise boosting of hierarchical zero-inflated count models, was used to relate the counts of each species to the environmental predictor variables while accounting for survey heterogeneity and the aggregated nature of sightings. The modeling technique allowed for complex non-linear relationships between response and predictor variables and interacting effects among predictors. Bootstrapping was used to derive estimates of the uncertainty in model predictions. For a complete description of the methods see Winship et al. (2018) Submission Package ID: RM4YYU |
Purpose | Marine birds have the potential to be affected by human activities in the ocean environment such as offshore wind energy development. This project was a partnership between the Bureau of Ocean Energy Management (BOEM) and NOAA National Centers for Coastal Ocean Science (NCCOS) through Inter-Agency Agreement Number M13PG00005 to develop maps of the spatial distributions of marine bird species in U.S. Atlantic OCS waters that can be used to inform marine spatial planning in the region and guide future data collection efforts. The analysis relied on large databases of marine bird sighting data provided by the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS) (Northwest Atlantic Seabird Catalog) and by the Canadian Wildlife Service, Environment and Climate Change Canada (CWS-ECCC) (Eastern Canada Seabirds at Sea (ECSAS) database). This project was conducted to inform BOEM’s renewable energy policy decisions in the OCS. Having the most up-to-date and comprehensive biogeographic information is an important part of BOEM’s process to identify and fill critical data gaps, and to assess the potential direct and indirect impacts of offshore renewable energy development on marine birds. Products from this assessment may also support coastal and ocean management efforts by other local, state and federal agencies working in the OCS region. |
