Multiscale observing system simulation experiments for iron fertilization in the Southern Ocean, Equatorial Pacific, and Northeast Pacific
Why we care Iron is a critical limiting nutrient for phytoplankton in the ocean. Iron fertilization adds this limiting nutrient to promote phytoplankton blooms as a way to take up carbon dioxide and store carbon when they sink. Unknowns on the effectiveness, measurement and monitoring need to be addressed. To address these unknowns, this project
Why we care There are several challenges that can limit the efficiency and effectiveness of marine carbon dioxide removal methods. One potential consequence of some methods is increased growth of organisms that build shells out of calcium carbonate, or calcification (shell building). Calcification releases carbon dioxide into seawater, which may reduce the efficiency of carbon
Engaging U.S. Commercial Fishing Community to Develop Recommendations for Fishery-Sensitive mCDR Governance, Collaborative Research and Monitoring, and Outreach to Fishing Communities
Why we care Marine carbon dioxide removal strategies will interact with fishery ecosystems, resources, and activities. It is important to engage with commercial fisheries early to develop an accurate understanding of governance concerns to build trust and fishery-sensitive governance. What we will doThe project will leverage existing networks of fishermen from the Northeast, Alaska, and
Community Sampling and Ocean Acidification Observations in South-central Alaska Why we careSoutheast Alaska experiences ocean acidification at a faster rate than other regions due to its cold water temperatures and ocean current patterns. Indigenous communities rely on a healthy marine ecosystem and the culturally and economically important species that are impacted. This long-term community science
Effects of OA on Alaskan and Arctic fishes: physiological sensitivity in a changing ecosystem
Why we care
There is significant concern about ocean acidification disrupting marine ecosystems, reducing productivity of important fishery resources, and impacting the communities that rely upon those resources. To predict the ecological and socioeconomic impacts of acidification, it is critical to
Resiliency and sensitivity of marine fish to elevated CO2: osmoregulatory neurosensory behavioral and metabolic responses in salmon and sablefish
Why we care
Elevated levels of marine carbon dioxide can disrupt how many marine fishes detect their environment, impairing their ability to respond appropriately to chemical, auditory, and visual cues. The mechanisms underlying differences in species
Effects of predicted changes in ocean pCO2 and interactions with other stressors on the physiology and behavior of commercially important crabs in Alaska
Why we care
Ocean acidification disrupts the internal acid-base balance of crabs and may hinder the creation and maintenance of shells. Previous studies on commercially important crab species in Alaska found that
Forecast effects of ocean acidification on Alaska crab and groundfish fisheries
Why we care
Ocean acidification (OA) is a multi-disciplinary problem that requires a combination of methods from oceanography, fisheries science, and social science to assess socio-economic impacts. While OA impact models developed to date capture some sources of measurement uncertainty, more remains and limits
Sustained Observations of Ocean Acidification in Alaska Coastal Seas
Why we care
Coastal regions around Alaska experience some of the most rapid and extensive progressions of ocean acidification (OA) in the United States. Assessments indicate that Alaska coastal communities have a varying degree of vulnerability to OA ranging from moderate to severe. Economically vital fishing
