This data collection contains geospatial data from models predicting the spatial distributions of deep-sea corals (DSCs) and hardbottom habitats offshore of the southeastern U.S. It includes a database (.csv text file) containing records of occurrence (presence-absence) for DSCs with associated measures of sampling effort and bottom type from 20 datasets comprised of data from visual field surveys conducted with underwater vehicles. It also includes raster datasets at 100 x 100 m spatial resolution depicting the median and coefficient variation of the predicted occurrence (occupancy probability) for 24 taxa of DSCs (23 genera, 1 family) and hardbottom habitats. Additional raster datasets depict the median and coefficient of variation of the predicted genus richness for the 23 genera of DSCs. The data collection also includes raster datasets at 100 x 100 m spatial resolution depicting each of the 62 spatial environmental predictors considered for fitting the models. For more information, see Poti et al. (2022). The project to compile this model took place between 2016 and 2021, however the model input data range from 2001-2018 and the model output covers the same timeframe.

Methods:

A database of DSC occurrences (presence-absence) with associated measures of sampling effort (i.e., area observed by a survey segment) and bottom type was compiled from 20 available datasets containing data from underwater visual surveys conducted between 2001 and 2018. Spatially-explicit hierarchical occupancy models were used to relate records of DSC and hardbottom habitat occurrence from the database to spatial environmental predictors characterizing the seafloor, oceanography, and geography of the study area in order to predict and map the estimated occurrence of 24 taxa of DSCs and hardbottom habitats across the study area. The models attempted to account for imperfect detection and thus standardize estimates of occurrence across taxa. Variability in model predictions was also mapped to provide a measure of the level of confidence in the model predictions. The models also predicted the genus richness for 23 genera of DSCs. For more details, see Poti et al. (2022).

Purpose The Bureau of Ocean Energy Management (BOEM) oversees the responsible development of offshore energy and mineral resources on the U.S. Outer Continental Shelf. Offshore energy projects often include activities that may physically disturb the seafloor and could negatively affect benthic biota. BOEM identified a need for information on the spatial distributions of sensitive benthic habitats, including deep-sea corals and hardbottom areas capable of supporting diverse benthic communities, offshore of the southeastern U.S. within the Atlantic Outer Continental Shelf region. Many deep-sea corals form complex three-dimensional structures that can increase local biodiversity by providing microhabitats for use by other species such as fishes, crustaceans, and echinoderms (Buhl-Mortensen et al. 2010). Areas with exposed hardbottom provide available surface for attachment of sessile invertebrates like deep-sea corals and may also be associated with greater diversity and abundance of large fish on the continental shelf offshore of the southeastern U.S. (Quattrini et al. 2004, Kendall et al. 2009, Taylor et al. 2016). Information on the spatial distributions of deep-sea corals and hardbottom habitats is needed to assess the potential impacts of activities that may disturb the seafloor and to develop mitigation measures to avoid or minimize these impacts. This study had two main objectives: (1) to compile a database of presence-absence observations of DSCs with associated measures of sampling effort and bottom type from available data collected by underwater visual surveys and (2) to develop predictive models that relate the occurrence (presence-absence) of deep-sea corals and hardbottom habitats to spatial environmental predictors in order to predict and map their potential spatial distributions offshore of the southeastern U.S.

  • Parameter or Variable: Occupancy Probability (calculated); Units: none; Observation Category: model output; Sampling Instrument: Models/Analyses > Data Analysis > Environmental Modeling; Sampling and Analyzing Method: A database containing presence-absence observations of DSCs with associated measures of sampling effort and bottom type was compiled from 20 datasets comprised of data from visual field surveys conducted with underwater vehicles between 2001 and 2018. The database records were integrated with spatial environmental predictors representing seafloor topography, substrate, oceanography, and geography in spatial predictive models. Spatially-explicit hierarchical occupancy models were developed in a Bayesian framework to predict and map the occurrence (occupancy probability) of 24 taxa of DSCs and hardbottom habitats across the study area. The models also predicted the genus richness for the 23 genera of DSCs included in the study. For more details, see Poti et al. (2022).; Data Quality Method: The models generated posterior probability distributions for occupancy probability and richness. The posterior median was selected as the best estimate of predicted occupancy probability and predicted genus richness. The posterior coefficient of variation (CV) was calculated as a measure of variability (i.e., confidence) in model predictions at each grid cell. Maps of predicted occurrence (occupancy probability) and predicted genus richness were reviewed by study authors and collaborators with expertise in the ecology of deep-sea corals and hardbottom habitats. See Poti et al. (2022) for details..
