Deep-sea coral and sponge presence and abundance (measured as catch per unit effort (CPUE) were generated based off data from bottom trawl surveys between 1993 to 2013. Sponge models were left at the class level due to taxonomic uncertainty. Models of coral were the combination of seven families (Acanthogorgidae, Paragorgidae, Isididae, Plexauridae, Primnoidae and Stylasteridae). One coral family, due to its dominance in the region, was modeled on its own. Another coral group, sea whips (order Pennatuloidea), were also modeled independently due to their dominance in soft substrate environments. All models are presented in the GeoTIFF format. Environmental layers used in the modeling of the taxa are also part of this data package. They include the parameters GeoTIFF rasters of latitude, longitude, bathymetry, mean bottom temperature for the region, current speed and direction for the deepest depth bin at each sampling point, ocean color, seafloor slope, mean current speed (exclusive of tides), and max tidal current predicted over a year. For details on the measurement of each environmental layer, see the journal article Rooper et al. (2017).

Predictive models of density, presence, and individual height were generated from deep-sea coral and sponge specimen collected during bottom trawl surveys conducted along the East Bering Sea continental slope (<1200 m). The taxonomic resolution was left at coarse levels (corals, sea whips, and sponges) due to uncertainty in identification and the uncommon encounter rate of individuals caught in the trawls. Structure-forming corals were modeled as an individual group while sea whip and sea pens were modeled together collectively as a group called sea whips. All sponges were modeled as a singular group. Environmental layers employed in the modeling process are also available as part of this package except for the sediment parameters which have been previously archived (Smith and McConnaughey 1999). They include the parameters latitude, longitude, bathymetry, max bottom temperature for the region, current speed for the deepest depth bin at each sampling point, ocean color, and seafloor slope. For details on the measurement or computation of each environmental layer, see the journal article Sigler et al. (2015). All models and environmental layers are available as GeoTIFF rasters.

Coral and sponge presence, abundance (measured as catch per unit effort (CPUE)), and diversity (number of coral families) models were generated based off of data from bottom trawl surveys in the Aleutian Islands, Alaska from 1991-2011 using the generalized additive modeling method at a 100 x 100 m spatial resolution. Sponge models were left at the phylum level due to taxonomic uncertainty. Greater certainty in coral taxonomy allowed for modeling of individual Stylasteridae and Primnoidae coral families. A further overall coral group modeling was conducted to include all hydrocoral and gorgonian corals identified. All models are presented in the GeoTIFF raster format. Environmental layers used in the modeling of the taxa are also part of this data package. They include the parameters GeoTIFF rasters of latitude, longitude, bathymetry, aspect relative to mean current, mean bottom temperature for the region, current speed and direction for the deepest depth bin at each sampling point, ocean color, seafloor rugosity, sediment type, seafloor slope, mean current speed (exclusive of tides), and max tidal current measured over a year. For details on the measurement of each environmental layer, see Rooper et al. (2014).

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.

Generalized linear models (GLM) generated for predicting the distribution of macroinvertebrate-sized hydroids, brittle stars, and short and tall sea pens that live in the Santa Barbara Channel (SBC) off California. Models contain probability of occurrence in the SBC from Refugio State Beach (34.58 N, 120.18 W) to Hueneme Canyon (34.18 N, 119.28W) along 5 survey blocks: Refugio, Coal Oil Point, Santa Barbara, Ventura, and Hueneme Canyon. Presence-absence data from geo-referenced video data and still images were fit to binomial GLMs with logit link functions (multiple logistic regression). For more details on the modeling process, see the journal article Krigsman et al. (2012). All models are presented in the GeoTIFF format.

This dataset includes predictive habitat models for deep-sea corals in Alaskan waters, including the U.S. Exclusive Economic Zone of several coral taxa at the order (Antipatharia and Scleractinia) and the suborder level (Alcyoniina, Calcaxonia, Filifera, Holaxonia, Scleraxonia, and Stolonifera). The fauna were modeled at a ~ 700 x 700 m spatial resolution with a variety physical, chemical, and environmnetal predictors under the MaxEnt framework with a spatial partioning cross-validation approach. For more details on the construction of the models, see Guinotte and Davies (2013). All models are present in GeoTIFF.

Predictive habitat models for deep-sea corals within the U.S. West Coast Exclusive Economic Zone were developed to aid future research and spatial mapping. Models were built at a 500 x 500 m spatial resolution with a range of physical, chemical, and environmental variables thought to influence the distribution of deep-sea corals. Models were generated using records, from a variety of sources, reliably identified at the order and suborder levels including Alcyoniina, Antipatharia, Calcaxonia, Holaxonia, Scleraxonia, and Scleracaxonia under the MaxEnt framework with a spatial spatial partitioning cross-validation approach. Further, models were generated for all taxa records with thresholded predicted outputs at the 0.5 and 0.75 cutoff presence/absence value. For more details on the construction of the models, see Guinotte and Davies (2014). All models are present in GeoTIFF format.
