--- attributes: ~ caption: "The figure shows changes over time in geographic distribution (left panel) and biomass (four panels at right) for various marine species along the Northeast Shelf. As waters in the region have warmed, the spatial distributions of many fish species have been shifting northward, while population trends of several marine species show more variability over time. The left panel shows shifts in spatial distribution over time for select fish species, based on their latitudinal centers of biomass. The four panels on right show biomass estimates for the same marine resource stocks. Gulf of Maine cod, a coldwater species, has not shifted in location but has declined in biomass, while black sea bass (a warmwater species) has moved northward and increased in biomass as waters have warmed. The lobster distribution shift reflects declines in productivity of the southern stock and increasing biomass of the northern stock.
