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.

Open Positions

Graduate student research assistant

The Ocean Acidification Research Center (OARC) is seeking a current, UAF graduate student for a research assistantship during the fall 2023 semester.  Students from any department with analytical chemistry experience are preferred, interest in oceanography desirable.  Please email Natalie Monacci for details.


Here are a few helpful links to learn more information about OA research in Alaska and around the globe.

Alaska’s longest continual ocean acidification mooring, nicknamed “GAKOA” (for Gulf of Alaska Ocean Acidification), just turned ten years old.
We are accepting proposals from current UAF students to add ocean acidification (OA) measurements to their research projects. Proposals are due March 15, 2023. View the ’Samples of Opportunity’ site for more information.

OARC is a member of the Marine Arctic Ecosystem Study (MARES) that won the 2019 Excellence in Partnership award from the National Oceanographic Partnership Program (NOPP). The award was announced in February 2020. The MARES project is an international, interagency partnership with more than 25 groups from federal, state, tribal, academic, and private groups in Alaska and Canada. The MARES project looked at more than 20 variables to understand the structure and function of the marine ecosystem in the Beaufort Sea. The MARES project was lead by Stantec’s Dr. Francis Weise. OARC deployed autonomous sensors to measure carbon parameters in the Alaskan and Canadian Beaufort Sea shelf near the Mackenzie River canyon.
