Projected Habitat Suitability Changes for 33 Marine Species on the Northeast US Shelf

33 marine species have projected habitat suitability changes on the Northeast US shelf. Changes are based on species distribution models fit to NOAA bottom trawl survey data, with positive values indicating increased suitability by 2040-2050 relative to a 1963-2005 baseline. The dataset was authored by Lauren A. Rogers of Stanford University and is available via the Biological and Chemical Oceanography Data Management Office.

Use Cases

• Projecting future species distributions based on modeled habitat suitability changes.
• Analyzing climate change impacts on marine ecosystems based on projected suitability shifts.
• Informing marine spatial planning and conservation efforts based on geospatial projections.
• Validating species distribution models using historical survey data from NOAA.

Strengths

• Includes projections for 33 distinct marine species.
• Models are based on historical bottom trawl survey data from NOAA spanning 1963 to 2005.
• Projections have a defined spatial resolution of 0.25 x 0.25 degrees.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
