This study analyzed thermohaline dynamics of the Gulf of Maine based on data published in 1968. It describes six water masses: Maine Surface Water, Maine Intermediate Water, and Maine Bottom Water as interior water masses; and Scotian Shelf Water, Slope Water, and Georges Bank Water as exterior water masses. ...
The Gulf of Maine's unusual geography and oceanography make it distinct from other continental shelf ecosystems. It has deep basins, shallow offshore banks that limit water flow between the Gulf and the open Atlantic Ocean, strong tidal mixing of it shallower waters, and a seasonal cycle of intense winter cooling, ...
This article provides an overview of how rivers, which tend to be acidic compared to the ocean, affect shellfish, with a focus on the Gulf of Maine.
Ocean acidification and/or warmer temperatures may affect immune response, parasite abundance and diversity, and bacterial infection of blue mussels. (Laboratory study)
Hard shell clams and eastern oysters exposed to moderate warming and ocean acidification conditions showed no sign of persistent oxidative stress. This indicates that long-term exposure to moderately elevated CO2 and temperature minimally affects the cellular redox status in these bivalve species and that the earlier observed negative physiological effects ...
Viability of copepod eggs and larvae was not affected by exposure to ocean acidification conditions. In contrast, warming by 2 or 4°C increased the viability of some eggs. (Laboratory study)
Ocean acidification may alter the biogeographical distribution of a non-calcifying red alga by affecting its photosynthesis and growth. (Laboratory study)
Bryozoan colonies were able to survive short-term exposure to high levels of ocean acidification at normal temperatures. However, its ability to calcify at higher temperatures was compromised.
Growth rate and biomass of a seaweed (the red alga Chrondrus crispus) increased only when ocean acidification was accompanied by warmer temperatures. Photosynthesis was reduced under ocean acidification conditions. (Laboratory study)
