Marine Life

The Mid-Atlantic region is well known for nutrient-rich and highly productive waters. Its estuaries, salt marshes, sea grasses, barrier islands, cold water corals, and submarine canyons provide spawning, nursery, and forage habitats that support diverse resident and migratory marine life including invertebrates, seabirds, fishes, and marine mammals.

Sea Scallops Average Abundance (SMAST)

This layer shows the average abundance (2003 - 2012) of Sea scallops, colored by percentile. Abundance of 1 or more represents an area with commercially viable scallop densities. This data product was created using the University of Massachusetts Dartmouth School of Marine Science and Technology (SMAST) video survey from 2003 through 2012 joined to the New England Fishery Management Council Swept Area Seabed Impact (SASI) model grid. The SMAST video survey covered the Continental Shelf from the southern Mid-Atlantic to the USA-Canadian border on eastern Georges Bank.

Essential Fish Habitats

This layer represents an overlay of Essential Fish Habitat (EFH) polygons for all 39 species under Federal management in the Mid-Atlantic and Northeast. It was developed for general visualization and informational purposes only and does not necessarily represent the most important habitats.

EFH is defined as those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity (16 U.S.C. 1802(10)). Waters include aquatic areas and their associated physical, chemical, and biological properties that are used by fish and may include aquatic areas historically used by fish where appropriate; substrate includes sediment, hard bottom, structures underlying the waters, and associated biological communities; necessary means the habitat required to support a sustainable fishery and the managed species' contribution to a healthy ecosystem; and spawning, breeding, feeding, or growth to maturity covers a species' full life cycle. See the NOAA Essential Fish Habitat Mapper for more information and for maps of individual species.

Sea Scallops Biomass, meat weight in kg (NEFSC) - Draft

This layer displays scallop biomass (meat weights in kilograms) from all NOAA Northeast Fisheries Science Center NEFSC scallop dredge surveys from 1966 to 2014. The NEFSC scallop survey program began in 1960 and had a major gear change in 1979. Since 1979 there have been other gear and vessel changes, for which the effects are generally small. In cases where it was deemed appropriate after study, correction factors have been applied to the data. These data are used to help assess the stock of scallops in the Northeast and Mid Atlantic. Other data that are collected during NEFSC scallop dredge surveys (but that are not shown here) include scallop shell heights, the number and height of dead scallop shells, any finfish, cephalopods and lobsters caught during the survey, as well as the presence/absence of other bivalve species (e.g., ocean quahogs, razor clams) and invertebrate species (e.g., sand dollars, anemones).

Fish Species Through Time

These data layers represent an analysis of Northeast Fisheries Science Center (NEFSC) bottom trawl survey data collected between 1972 and 2017 and show where selected individual fish species have consistently been found in higher biomass numbers over time (by decade). The species included are those that are important recreationally and/or commercially in the Mid-Atlantic region and are also well represented in the trawl survey data. Employing analysis methods developed by NEFSC and Rutgers University, an interpolated biomass surface was derived for each species, each year and each season. Each interpolated surface was then analyzed to determine areas of high biomass. Two thresholds were used – “high” and “highest”. These thresholds represent biomass values in the top 25% and top 10%, respectively, of all biomass values across a given decade (for an individual species and season). These areas of high biomass by year were then combined by decade (e.g., 1990 – 1999) and areas with high year-to-year variability were removed. Areas where a species was present, regardless of biomass, were also developed. Average interpolated biomass for the most recent time period (2010 to 2016 or 2017) can be found for individual species under Marine Life Library (Species Specific) and Fish Biomass NEFSC Species. Interpolated biomass for species groupings can also be found under Marine Life and Fish – Fall or Fish – Spring. These data were developed under a grant from the Virginia Coastal Zone Management Program.

Notes:

The NEFSC trawl survey changed boats and gear in 2009, resulting in potentially different catch rates for some species. Calibration factors have been developed by NEFSC for some species so comparison between pre- and post-2009 datasets is possible, and those calibration factors have been applied in this analysis where applicable, however the calibration factors are imperfect and were not developed for all species. Some species (e.g. Atlantic Herring) were not targeted by the Trawl survey. As a result, the visualization of high biomass areas may be incomplete in these cases. Finally, these layers do not include state-run trawl surveys such as NEAMAP. Therefore, these data only account for the biomass values within the NEFSC trawl survey, and may miss some important areas of high biomass near the coast.

Benthic Habitats (North)

Benthic habitats are based on Ecological Marine Units (EMUs), which represent the three-way combination of depth, sediment grain size and seabed forms based on the ecological thresholds revealed by the organism relationships. Benthic habitats are combinations of EMUs considered with their species assemblages. Thresholds were created by classifying grab samples into organism groups based on similarities in the composition and abundance of the benthic species using hierarchical cluster analysis. To perform this analysis, each grab sample was classified to an organism group, then overlaid on standardized base maps of depth, sediment grain size and seabed forms, and attributed with the information taken from the classified data. Regression trees were built individually for each physical variable to identify critical thresholds that separated sets of organism groups from each other. Regression trees were also built using all variables collectively to identify which variables were driving the organism differences. Each analysis was performed separately by ecological subregion after data exploration revealed that the relationships between genera and physical factors differed markedly among subregions.

Habitat for Soft Corals (Modeled)

This dataset depicts the predicted likelihood of suitable habitat for deep-sea corals in the order Alcyonacea in the U.S. Northeast Atlantic and Mid-Atlantic as coral habitat suitability likelihood classes derived from a categorical reclassification of the logistic output of a maximum entropy (MaxEnt) model derived from coral presence locations and environmental predictor variables at 370.65m resolution.

Source: NOAA/NOS National Centers for Coastal Ocean Science (NCCOS)

Notes:

Deep-sea coral is a diverse and valuable resource that, among many things, provides habitat for fish and invertebrates. Because of their slow growth rates and vulnerability to bottom disturbance, deep-sea coral ecosystems are particularly important to conserve. Mapping the exact distribution of deep-sea coral is challenging because because of the logistical difficulty and expense of surveying the deep ocean. Predictive modeling of deep-sea coral habitats is essential for supporting conservation planning and for targeting areas for future mapping and exploration. Modeling can also lead to insights into the environmental factors driving the distribution of deep-sea corals, helping to build our knowledge base of how these unique ecosystems function.

Deep-Sea Soft Coral Habitat Suitability

Deep-sea corals, also known as cold water corals, create complex communities that provide habitat for a variety of invertebrate and fish species, such as grouper, snapper, and sea bass. The map depicts the relative likelihood of finding suitable habitat for soft corals at a given location and is a prediction based on a statistical model relating several environmental characteristics to the presence of soft corals using observations of soft coral. Soft corals, unlike stony corals, do not form calcium-based skeletons. A common example of a soft coral is a sea fan. Please also reference the "Deep-Sea Stony Coral Habitat Suitability" layer. Predictions from these habitat suitability models can be used to support conservation and management of deep-sea corals and to assist with targeting areas for mapping and exploration.

Birds - Stage V2

Marine life data products were developed through a partnership with the Marine-life Data and Analysis Team (MDAT), who collaborated with the Northeast Regional Planning Body (RPB) and expert work groups to produce maps characterizing the predicted distribution and abundance for 29 marine mammal species and species guilds, 40 bird species, and the surveyed biomass of 82 fish species.

Based on RPB, work group, and public feedback, we further aggregated these base products into maps for various species groups within each marine life category to provide additional information to support different management and conservation activities. To facilitate targeted data exploration and decision making, we developed synthetic maps characterizing the abundance, richness, diversity, and core relative abundance area richness (50%) for these groups of species and for complete taxa. These synthetic map products are meant to supplement the individual species outputs.

All map products were informed by public input, work groups composed of over 80 regional scientists and managers, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region.

Source: Marine Life Data and Analysis Team V2

Notes:

The synthetic map products provide a means to distill multiple data layers and time periods into simplified maps. Development of these maps required decisions and thresholds that are explained in the information accompanying each layer. These decisions were made after conducting research, development, and testing of several options, as well as incorporating feedback from expert work group members and the RPB. Understanding these decisions and thresholds is crucial to proper interpretation of these map products.

Species group definitions were developed by MDAT with guidance and input from the marine life expert work groups and RPB. There are three main caveats when considering use of the species groups: (1) The species within these groups represent only those modeled or mapped by MDAT. As an example, there may be additional “migrant” bird species not captured in this species group because there were insufficient observations available to develop an individual species model. (2) The groups are not exhaustive. There is potential for additional groups, but the data and information available at this time do not support their formation. In order to develop species membership lists for all groups, we relied on expert judgment and published sources of information. (3) Group level products (relative abundance, richness, and core relative abundance area richness) were created with the normalized annual prediction models, and so should be interpreted accordingly.

All Avian Species: Core Abundance Area - Mid-Atlantic scale / Birds - Stage V2

The purpose of a core abundance area map is to represent the smallest area containing 50% of the predicted abundance of each species. Summing all the cells (pixels) in the species' normalized annual relative abundance distribution product gives the total predicted relative abundance. Core area is calculated by ranking cells by their relative abundance value from greatest to least, then summing cells with the highest abundance values until the total is equal to or greater than 50% of the total predicted relative abundance. For the Mid-Atlantic scale product, only the predicted relative abundance values within the Mid-Atlantic are used in the ranking.

Summing all the cells (pixels) in the species' normalized annual relative abundance distribution product gives the total predicted relative abundance. Core area is calculated by ranking cells by their relative abundance value from greatest to least, then summing cells with the highest abundance values until the total is equal to or greater than 50% of the total predicted relative abundance. For the Mid-Atlantic scale product, only the predicted relative abundance values within the Mid-Atlantic are used in the ranking.

Marine Mammals - Stage V2

Marine life data products were developed through a partnership with the Marine-life Data and Analysis Team (MDAT), who collaborated with the Northeast Regional Planning Body (RPB) and expert work groups to produce maps characterizing the predicted distribution and abundance for 29 marine mammal species and species guilds, 40 bird species, and the surveyed biomass of 82 fish species.

Based on RPB, work group, and public feedback, we further aggregated these base products into maps for various species groups within each marine life category to provide additional information to support different management and conservation activities. To facilitate targeted data exploration and decision making, we developed synthetic maps characterizing the abundance, richness, diversity, and core relative abundance area richness (50%) for these groups of species and for complete taxa. These synthetic map products are meant to supplement the individual species outputs.

All map products were informed by public input, work groups composed of over 80 regional scientists and managers, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region.

Source: Marine Life Data and Analysis Team V2

Notes:

The synthetic map products provide a means to distill multiple data layers and time periods into simplified maps. Development of these maps required decisions and thresholds that are explained in the information accompanying each layer. These decisions were made after conducting research, development, and testing of several options, as well as incorporating feedback from expert work group members and the RPB. Understanding these decisions and thresholds is crucial to proper interpretation of these map products.

Species group definitions were developed by MDAT with guidance and input from the marine life expert work groups and RPB. There are three main caveats when considering use of the species groups: (1) The species within these groups represent only those modeled or mapped by MDAT. As an example, there may be additional “migrant” bird species not captured in this species group because there were insufficient observations available to develop an individual species model. (2) The groups are not exhaustive. There is potential for additional groups, but the data and information available at this time do not support their formation. In order to develop species membership lists for all groups, we relied on expert judgment and published sources of information. (3) Group level products (relative abundance, richness, and core relative abundance area richness) were created with the normalized annual prediction models, and so should be interpreted accordingly.

All Cetaceans: Core Abundance Area - Mid-Atlantic scale / Marine Mammals - Stage V2

The purpose of a core abundance area map is to represent the smallest area containing 50% of the predicted abundance of each species. Summing all the cells (pixels) in the species' normalized annual relative abundance distribution product gives the total predicted relative abundance. Core area is calculated by ranking cells by their relative abundance value from greatest to least, then summing cells with the highest abundance values until the total is equal to or greater than 50% of the total predicted relative abundance. For the Mid-Atlantic scale product, only the predicted relative abundance values within the Mid-Atlantic are used in the ranking.

Fish - Stage V2

Marine life data products were developed through a partnership with the Marine-life Data and Analysis Team (MDAT), who collaborated with the Northeast Regional Planning Body (RPB) and expert work groups to produce maps characterizing the predicted distribution and abundance for 29 marine mammal species and species guilds, 40 bird species, and the surveyed biomass of 82 fish species.

Based on RPB, work group, and public feedback, we further aggregated these base products into maps for various species groups within each marine life category to provide additional information to support different management and conservation activities. To facilitate targeted data exploration and decision making, we developed synthetic maps characterizing the abundance, richness, diversity, and core relative abundance area richness (50%) for these groups of species and for complete taxa. These synthetic map products are meant to supplement the individual species outputs.

All map products were informed by public input, work groups composed of over 80 regional scientists and managers, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region.

Source: Marine Life Data and Analysis Team V2

Notes:

The synthetic map products provide a means to distill multiple data layers and time periods into simplified maps. Development of these maps required decisions and thresholds that are explained in the information accompanying each layer. These decisions were made after conducting research, development, and testing of several options, as well as incorporating feedback from expert work group members and the RPB. Understanding these decisions and thresholds is crucial to proper interpretation of these map products.

Species group definitions were developed by MDAT with guidance and input from the marine life expert work groups and RPB. There are three main caveats when considering use of the species groups: (1) The species within these groups represent only those modeled or mapped by MDAT. As an example, there may be additional “migrant” bird species not captured in this species group because there were insufficient observations available to develop an individual species model. (2) The groups are not exhaustive. There is potential for additional groups, but the data and information available at this time do not support their formation. In order to develop species membership lists for all groups, we relied on expert judgment and published sources of information. (3) Group level products (relative abundance, richness, and core relative abundance area richness) were created with the normalized annual prediction models, and so should be interpreted accordingly.

The result is the total interpolated biomass of all individuals (of the included species) in that cell. Note that individual fish species IDW maps calculate biomass on a natural logarithm scale, and these aggregate maps are raw biomass.

Demersal Fish: Species Richness / Fish - Stage V2

For all species together and for each group of species, species richness maps are calculated in a Geographic Information System (GIS) by stacking each individual species’ predicted presence or absence and counting the total number of species present in each cell. Some mammal species were modeled as a group to create the most robust outputs (e.g., beaked whales, pilot whales). To most accurately calculate species richness, the species within these groups were re-modeled individually and counted as individual species.

Demersal Fish: Core Biomass Area - Mid-Atlantic scale / Fish - Stage V2

The purpose of a core biomass area map is to represent the smallest area containing 50% of the interpolated biomass of each fish species. Summing all the cells in the IDW product gives the total interpolated biomass. Core area is calculated by ranking cells by their biomass value from greatest to least, then summing cells with the highest biomass values until the total is equal to or greater than 50% of the total interpolated biomass. For the Mid-Atlantic scale product, only the predicted biomass values within the Mid-Atlantic are used in the ranking.

Birds - V1

Marine life data products were developed through a partnership with the Marine-life Data and Analysis Team (MDAT), who collaborated with the Northeast Regional Planning Body (RPB) and expert work groups to produce maps characterizing the predicted distribution and abundance for 29 marine mammal species and species guilds, 40 bird species, and the surveyed biomass of 82 fish species.

Based on RPB, work group, and public feedback, we further aggregated these base products into maps for various species groups within each marine life category to provide additional information to support different management and conservation activities. To facilitate targeted data exploration and decision making, we developed synthetic maps characterizing the abundance, richness, diversity, and core relative abundance area richness (50%) for these groups of species and for complete taxa. These synthetic map products are meant to supplement the individual species outputs.

All map products were informed by public input, work groups composed of over 80 regional scientists and managers, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region.

Source: Marine Life Data and Analysis Team

Notes:

The synthetic map products provide a means to distill multiple data layers and time periods into simplified maps. Development of these maps required decisions and thresholds that are explained in the information accompanying each layer. These decisions were made after conducting research, development, and testing of several options, as well as incorporating feedback from expert work group members and the RPB. Understanding these decisions and thresholds is crucial to proper interpretation of these map products.

Species group definitions were developed by MDAT with guidance and input from the marine life expert work groups and RPB. There are three main caveats when considering use of the species groups: (1) The species within these groups represent only those modeled or mapped by MDAT. As an example, there may be additional “migrant” bird species not captured in this species group because there were insufficient observations available to develop an individual species model. (2) The groups are not exhaustive. There is potential for additional groups, but the data and information available at this time do not support their formation. In order to develop species membership lists for all groups, we relied on expert judgment and published sources of information. (3) Group level products (relative abundance, richness, and core relative abundance area richness) were created with the normalized annual prediction models, and so should be interpreted accordingly.

Offshore/Pelagic Species: Core Abundance Area - Mid-Atlantic scale / Birds - V1

The purpose of a core abundance area map is to represent the smallest area containing 50% of the predicted abundance of each species. Summing all the cells (pixels) in the species' normalized annual relative abundance distribution product gives the total predicted relative abundance. Core area is calculated by ranking cells by their relative abundance value from greatest to least, then summing cells with the highest abundance values until the total is equal to or greater than 50% of the total predicted relative abundance. For the Mid-Atlantic scale product, only the predicted relative abundance values within the Mid-Atlantic are used in the ranking.

Fish eaters: Core Abundance Area - Mid-Atlantic scale / Birds - V1

The purpose of a core abundance area map is to represent the smallest area containing 50% of the predicted abundance of each species. Summing all the cells (pixels) in the species' normalized annual relative abundance distribution product gives the total predicted relative abundance. Core area is calculated by ranking cells by their relative abundance value from greatest to least, then summing cells with the highest abundance values until the total is equal to or greater than 50% of the total predicted relative abundance. For the Mid-Atlantic scale product, only the predicted relative abundance values within the Mid-Atlantic are used in the ranking.

Fish - V1

Marine life data products were developed through a partnership with the Marine-life Data and Analysis Team (MDAT), who collaborated with the Northeast Regional Planning Body (RPB) and expert work groups to produce maps characterizing the predicted distribution and abundance for 29 marine mammal species and species guilds, 40 bird species, and the surveyed biomass of 82 fish species.

Based on RPB, work group, and public feedback, we further aggregated these base products into maps for various species groups within each marine life category to provide additional information to support different management and conservation activities. To facilitate targeted data exploration and decision making, we developed synthetic maps characterizing the abundance, richness, diversity, and core relative abundance area richness (50%) for these groups of species and for complete taxa. These synthetic map products are meant to supplement the individual species outputs.

All map products were informed by public input, work groups composed of over 80 regional scientists and managers, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region.

Source: Marine Life Data and Analysis Team

Notes:

The synthetic map products provide a means to distill multiple data layers and time periods into simplified maps. Development of these maps required decisions and thresholds that are explained in the information accompanying each layer. These decisions were made after conducting research, development, and testing of several options, as well as incorporating feedback from expert work group members and the RPB. Understanding these decisions and thresholds is crucial to proper interpretation of these map products.

Species group definitions were developed by MDAT with guidance and input from the marine life expert work groups and RPB. There are three main caveats when considering use of the species groups: (1) The species within these groups represent only those modeled or mapped by MDAT. As an example, there may be additional “migrant” bird species not captured in this species group because there were insufficient observations available to develop an individual species model. (2) The groups are not exhaustive. There is potential for additional groups, but the data and information available at this time do not support their formation. In order to develop species membership lists for all groups, we relied on expert judgment and published sources of information. (3) Group level products (relative abundance, richness, and core relative abundance area richness) were created with the normalized annual prediction models, and so should be interpreted accordingly.

These are species under a Mid-Atlantic Fishery Management Council Fisheries Management Plan. For all species together and for each group of species, species richness maps are calculated in a Geographic Information System (GIS) by stacking each individual species’ predicted presence or absence and counting the total number of species present in each cell. Some mammal species were modeled as a group to create the most robust outputs (e.g., beaked whales, pilot whales). To most accurately calculate species richness, the species within these groups were re-modeled individually and counted as individual species.

MAFMC FMPs: Core Biomass Area - Mid-Atlantic scale / Fish - V1

These are species under a Mid-Atlantic Fishery Management Council Fisheries Management Plan. The purpose of a core biomass area map is to represent the smallest area containing 50% of the interpolated biomass of each fish species. Summing all the cells in the IDW product gives the total interpolated biomass. Core area is calculated by ranking cells by their biomass value from greatest to least, then summing cells with the highest biomass values until the total is equal to or greater than 50% of the total interpolated biomass. For the Mid-Atlantic scale product, only the predicted biomass values within the Mid-Atlantic are used in the ranking.

NEFMC Monkfish: Biomass / Fish - V1

This is for the New England Fishery Management Council Monkfish Fisheries Management Plan. For all fish species together and for each group of species, total biomass maps are calculated in a Geographic Information System (GIS) by stacking each individual species’ Inverse Distance Weighted (IDW) interpolation layers and summing the values of the pixels in each resulting “column”. The result is the total interpolated biomass of all individuals (of the included species) in that cell. Note that individual fish species IDW maps calculate biomass on a natural logarithm scale, and these aggregate maps are raw biomass.

Marine Mammals - V1

Marine life data products were developed through a partnership with the Marine-life Data and Analysis Team (MDAT), who collaborated with the Northeast Regional Planning Body (RPB) and expert work groups to produce maps characterizing the predicted distribution and abundance for 29 marine mammal species and species guilds, 40 bird species, and the surveyed biomass of 82 fish species.

Based on RPB, work group, and public feedback, we further aggregated these base products into maps for various species groups within each marine life category to provide additional information to support different management and conservation activities. To facilitate targeted data exploration and decision making, we developed synthetic maps characterizing the abundance, richness, diversity, and core relative abundance area richness (50%) for these groups of species and for complete taxa. These synthetic map products are meant to supplement the individual species outputs.

All map products were informed by public input, work groups composed of over 80 regional scientists and managers, the Ecosystem Based Management Work Group, and similar proceedings in the Mid-Atlantic region.

Source: Marine Life Data and Analysis Team

Notes:

The synthetic map products provide a means to distill multiple data layers and time periods into simplified maps. Development of these maps required decisions and thresholds that are explained in the information accompanying each layer. These decisions were made after conducting research, development, and testing of several options, as well as incorporating feedback from expert work group members and the RPB. Understanding these decisions and thresholds is crucial to proper interpretation of these map products.

Species group definitions were developed by MDAT with guidance and input from the marine life expert work groups and RPB. There are three main caveats when considering use of the species groups: (1) The species within these groups represent only those modeled or mapped by MDAT. As an example, there may be additional “migrant” bird species not captured in this species group because there were insufficient observations available to develop an individual species model. (2) The groups are not exhaustive. There is potential for additional groups, but the data and information available at this time do not support their formation. In order to develop species membership lists for all groups, we relied on expert judgment and published sources of information. (3) Group level products (relative abundance, richness, and core relative abundance area richness) were created with the normalized annual prediction models, and so should be interpreted accordingly.

Sound sensitivity Medium frequency: Core Abundance Area - Mid-Atlantic scale / Marine Mammals - V1

The purpose of a core abundance area map is to represent the smallest area containing 50% of the predicted abundance of each species. Summing all the cells (pixels) in the species' normalized annual relative abundance distribution product gives the total predicted relative abundance. Core area is calculated by ranking cells by their relative abundance value from greatest to least, then summing cells with the highest abundance values until the total is equal to or greater than 50% of the total predicted relative abundance. For the Mid-Atlantic scale product, only the predicted relative abundance values within the Mid-Atlantic are used in the ranking.

Sperm and beaked whales: Abundance / Marine Mammals - V1

For all species together and for each group of species, total abundance maps are calculated in a Geographic Information System (GIS) by stacking each individual species’ predicted annual abundance layers and summing the values of the pixels in each resulting “column”. The result is the total predicted abundance of all individuals (of the included species) in that cell.

Sperm and beaked whales: Species Richness / Marine Mammals - V1

For all species together and for each group of species, species richness maps are calculated in a Geographic Information System (GIS) by stacking each individual species’ predicted presence or absence and counting the total number of species present in each cell. Some mammal species were modeled as a group to create the most robust outputs (e.g., beaked whales, pilot whales). To most accurately calculate species richness, the species within these groups were re-modeled individually and counted as individual species.
