New England

The New England Region waters are highly productive with a long history of extensive commercial fishing. Ocean acidification research in the area aims to determine how the major changes in regional ocean chemistry and conditions affect economically important species to better inform and prepare local industries and communities.

Understanding OA impacts for prediction and management

The New England Region geographically includes the Gulf of Maine, Georges Bank, and Scotian Shelf. Temperature changes, which are three times greater than the global average, and regional ocean circulation patterns of various water masses drive ocean acidification in this region. Precipitation during winter and spring that freshwater influx from riverine sources and contributes to eutrophication also influence corrosive conditions. Understanding how physical drivers influence ocean acidification in the surface and bottom waters is critical due to the commercial and recreational use of the water column and benthos. Economically important species such as the Atlantic scallop and American lobster are impacted by regional changes in ocean chemistry and pose a threat to the fishing and aquaculture industries and the economy of the region. Fisheries landings in the New England Region totaled $1.2 billion in 2015 with Atlantic sea scallops and American lobsters accounting for 73% of the total landings making the fishing and marine aquaculture industry particularly vulnerable to changes in ocean chemistry.

Tracking progress of ocean acidification research in New England

The research goals in the New England Region are to:

  • Improve regional biogeochemical characterization and understanding of trends and dynamics of ocean pH, particularly in response to temperature and riverine influence, to develop dynamic regional forecasts of ocean acidification (OA)
  • Understand the response of critical marine species under multi-stressor (low pH, high temperature, low oxygen) conditions and assess adaptive capacity to OA to inform ecosystem management
  • Use new knowledge to assess OA impacts to communities and economies to include OA into regional management plans and evaluate the costs and benefits of various mitigation and adaptation strategies.

The following charts represent the mid-point progress in implementing research actions that focus on the New England Region according to the NOAA Ocean, Coastal, and Great Lakes Acidification Research Plan.

A buoy moored in the Gulf of Maine monitors changes in the carbonate chemistry. This buoy plays a key role in a regional monitoring portfolio that supports our understanding of local changes to ocean conditions. In 2023, the Gulf of Maine time-series captured an unusual and long-lasting algal bloom event, an event that was first detected in unprecedented pCO2 drawdown levels in early April 2023. More information on the buoy and its data are available here. Researchers at NOAA’s Pacific Marine Environmental Laboratory and the University of New Hampshire’s Coastal Carbon Group coordinate the operation and data collection for this buoy. This work is supported by NOAA’s Ocean Acidification Program and the Integrated Ocean Observing System.

Bioeconomic models are a multidisciplinary tool that use oceanography, fisheries science and social science to assess socioeconomic impacts. Funded by the Ocean Acidification Program, researchers at the Alaska Fisheries Science Center use a bioeconomic model to study the impacts of ocean acidification on Eastern Bering Sea crab, northern rock sole and Alaska cod. The goal is to predict how ocean acidification will affect abundance yields and income generated by the fisheries. This work informs the potential economic impacts of ocean acidification and future decision making and research planning.

Long-term declines of red king crab in Bristol Bay, Alaska may be partially attributed to ocean acidification conditions. These impacts may be partially responsible for the fishery closures during the 2021–2022 and 2022–2023 seasons. Researchers found that ocean acidification negatively impacts Alaskan crabs generally by changing physiological processes, decreasing growth, increasing death rates and reducing shell thickness. Funded by the Ocean Acidification Program, scientists at the Alaska Fisheries Science Center continue to investigate the responses of early life history stages and study the potential of various Alaska crabs to acclimate to changing conditions. Results will inform models that will use the parameters studied to predict the effects of future ocean acidification on the populations of red king crab in Bristol Bay as well as on the fisheries that depend on them. Fishery managers will better be able to anticipate and manage stocks if changing ocean chemistry affects stock productivity and thus the maximum sustainable yield.

Understanding seasonal changes in ocean acidification in Alaskan waters and the potential impacts to the multi-billion-dollar fishery sector is a main priority. Through work funded by NOAA’s Ocean Acidification Program, the Pacific Marine Environmental Laboratory developed a model capable of depicting past ocean chemistry conditions for the Bering Sea and is now testing the ability of this model to forecast future conditions. This model is being used to develop an ocean acidification indicator provided to fisheries managers in the annual NOAA Eastern Bering Sea Ecosystem Status Report.
