US Regional Networks

California Current Acidification Network (C-CAN)

The California Current Acidification Network or C-CAN, founded in 2009, is a collaboration of interdisciplinary scientists, resource managers, industry and others from local, state, federal and tribal levels dedicated to advancing the understanding of ocean acidification and its effects on the biological resources of the US west coast. C-CAN first convened in 2010 in response to a growing realization that declines in shellfish hatchery production corresponded to coastal upwelling of low pH waters. The initial workshop brought together leading shellfish industry representatives, coastal managers, researchers, Sea Grant programs, and Integrated Ocean Observing Systems to increase collective understanding of OA effects on the nearshore environment. C-CAN has since expanded to include other ocean-dependent industries, environmental advocacy groups, regulatory agencies, and tribal groups. The overarching goal of C-CAN is to coordinate and standardize OA measurement and data collection practices, ensuring data accessibility, utility, and application. C-CAN facilitates and enhances communications and research collaborations among scientists, academia, agencies and industry.

Northeast Coastal Acidification Network (NECAN)

The Northeast Coastal Acidification Network or NECAN serves as a regional organization working to synthesize and disseminate ocean acidification information in an effort to better inform stakeholders of the issue and solicit critical data and information needs which can guide strategic science investments in coming years. The NECAN is a joint agency, scientific, industry partnership established under the Northeastern Regional Association of Coastal and Ocean Observing Systems (NERACOOS) to review and assess the most recent scientific, technical and socio-economic information relevant to the economically important marine organisms potentially impacted by ocean and coastal acidification within this region. NECAN’s focus encompasses the waters from Long Island Sound, Georges Bank, the Gulf of Maine and Browns Bank, and Sable Island Bank out to the shelf-break. The NECAN region represents some of the most valuable marine resource real-estate in the world providing direct economic benefit to at least five states (NY, CT, MA, NH, and ME).

Southeast Ocean and Coastal Acidification Network (SOCAN)

Representatives of several stakeholder groups in the Southeast have expressed interest in enhancing collaborations and communications to better understand ocean and coastal acidification (OA) drivers throughout this region, including, but not limited to, approaches to monitoring changing ocean chemistry; evaluating the state-of-ocean and coastal acidification science including eutrophication and hypoxia in coastal areas; and identifying vulnerable species and ecosystems. The Southeast Coastal Ocean Observing Regional Association (SECOORA), in partnership with NOAA’s Ocean Acidification Program (OAP), is facilitating conversations among regional stakeholders to advance a Southeast Ocean and Coastal Acidification Network (SOCAN). Similar Ocean Acidification Networks are in existence in other regions and have proven to be successful mechanisms for catalyzing unique partnerships and leveraging assets in times of constrained budgetary resources. SOCAN recently initiated a webinar series exploring how ocean acidification is or may affect marine resources in the Southeast. Information about the network, the 2015 webinar series and getting involved with SOCAN can be found at:

Alaska Ocean Acidification Network

Launched in 2016, the Alaska Ocean Acidification Network is an initiative designed to expand the understanding of ocean acidification processes and consequences in Alaska, as well as potential adaptation and mitigation actions. The network is the fourth regional ocean acidification network in the US, and will help connect scientists and stakeholder communities, recommend regional priorities, share data, and determine best practices for monitoring. Among the roles of the network is hosting a comprehensive website with resources for both researchers and the general public. The site includes information on monitoring projects around the state, current trends and forecasts, impacts to Alaska marine life, links to databases and journal articles, and a listing of experts and their specialties.

Gulf of Mexico Coastal Acidification Network (GCAN)

The Gulf of Mexico Ocean Acidification Network (GCAN) is a collaboration between the Gulf of Mexico Coastal Ocean Observing System Regional Association (GCOOS), the National Oceanic and Atmospheric Administration’s Ocean Acidification Program (NOAA OAP), federal and state agency representatives, resource managers, industry partners and research scientists. The mission of GCAN is to identify critical vulnerabilities of the Gulf of Mexico ecosystem that may be impacted by ocean acidification, foster collaborations to increase ocean observations, and develop strategies to mitigate impacts from ocean acidification.

Mid-Atlantic Coastal Acidification Network (MACAN)

The Mid-Atlantic Coastal Acidification Network (MACAN) works to develop a better understanding of the processes associated with estuarine, coastal, and ocean acidification, predict the consequences for marine resources, and devise local adaptation strategies that enable communities and industries to better prepare and adapt. MACAN is a nexus of scientists, federal and state agency representatives, resource managers, and affected industry partners who seek to coordinate and guide regional observing, research, and modeling of ocean and coastal acidification.

MACAN serves as an information hub and exchange among research, industry, and resource managers. MACAN focuses on waters and impacted species from south of Long Island down to Virginia.  Network members work collaboratively on identifying and pursuing opportunities to address coastal and ocean acidification in the Mid-Atlantic, building upon the skills and interest of individual members. The Network provides a forum to share best practices in monitoring and sampling collection. MACAN was established by the Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS) and the Mid-Atlantic Regional Council on the Ocean (MARCO).
