The Northeast Coastal Acidification Network (NECAN) held a workshop November 2-3, 2023 to identify and recommend monitoring priorities for ocean acidification in the NECAN region. Prior to the workshop, NECAN had submitted monitoring needs to the Interagency Working Group on Ocean Acidification. One of the outcomes of the workshop was ...

Abstract: Many studies have examined the vulnerability of calcifying organisms, such as the eastern oyster (Crassostrea virginica), to externally forced ocean acidification, but the opposite interaction whereby oysters alter their local carbonate conditions has received far less attention. We present an exploratory model for isolating the impact that net calcification and ...

Abstract: Estuaries may be uniquely susceptible to the combined acidification pressures of atmospherically driven ocean acidification (OA), biologically driven CO2 inputs from the estuary itself, and terrestrially derived freshwater inputs. This study utilized continuous measurements of total alkalinity (TA) and the partial pressure of carbon dioxide (pCO2) from the mouth of ...

One page document summarizing the impact of ocean and coastal acidification on the Massachusetts Shellfish Industry. 

The U.S. Northeast Continental Shelf marine ecosystem has warmed much faster than the global ocean and it is expected that this enhanced warming will continue through this century. Here, we used a high-resolution global climate model and historical observations of species distributions from a trawl survey to examine changes in ...

Exponentially rising CO2 (currently ~400 µatm) is driving climate change and causing acidification of both marine and freshwater environments. CO2 directly affects acid–base and ion regulation, respiratory function and aerobic performance in aquatic animals. Elevated CO2 projected for end of this century (e.g. 800–1000 µatm) can also impact physiology, and have substantial ...
