Climate change monitoring for marine fisheries and habitats

Climate change has had a growing influence on how we manage fisheries. DMF’s Fisheries Habitat Program implements the agency’s climate change strategy, including the collection of seafloor temperature data.


Climate change is expected to alter Massachusetts’ coastal areas,  including its ecosystems, fisheries habitats, and coastal communities. Potential changes include:

  • Increases in water temperature
  • Increases in frequency and intensity of regional precipitation
  • Decreases in salinity and ocean pH levels

Minor changes to the climate can threaten biodiversity and the health of our fisheries. In response to these challenges, DMF develops climate based fisheries management strategies. These strategies address ecosystem changes resulting from climate change to improve fisheries sustainability.

DMF also maintains data of the seafloor temperature that is accessible to the public. To request this data, contact Mark Rousseau at
