Ocean Acidification Research Center

Ocean acidification (OA) is the result of anthropogenic increases in atmospheric carbon dioxide that is later absorbed by the ocean. This change in ocean chemistry makes the global oceans more acidic. Concerns over increasing acidity in Alaska and how this phenomenon will impact Alaska’s Blue Economy spurred the creation of the Ocean Acidification Research Center (OARC) within the College of Fisheries and Ocean Sciences (CFOS) at the University of Alaska Fairbanks (UAF).

Placement of this center in Alaska is critical to the state’s long-term interests because the region will experience the effects of ocean acidification faster and to a greater degree than in lower latitudes due to colder water temperatures, ocean circulation patterns, and highly productive continental shelves. These characteristics act to enhance the transport of carbon dioxide (CO2) from the atmosphere into the ocean, which may accelerate acidification.

OARC Objectives

  1. Conduct research into OA, particularly in Alaskan waters, to determine the intensity, duration, and extent of OA around the state. We achieve this by long-term autonomous monitoring and modeling efforts, conducting field observations in highly sensitive areas, and quantifying physiological responses of vulnerable and commercially viable species.
  2. Serve the public and private sectors by providing access to OARC-generated data, training students and citizen scientists, and accepting seawater samples to be run at cost.
