Pacific Islands CASC

Established in 2012, the Pacific Islands CASC provides regionally-relevant scientific information, tools, and techniques to resource managers and communities in Hawai'i and the U.S.-Affiliated Pacific Islands.

Map of the Pacific Islands CASC (PI-CASC) region and consortium members. The PI-CASC serves the region including American Samoa, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia, Guam, Hawai'i, Palau, and the Republic of the Marshall Islands. The PI-CASC's consortium includes the University of Hawaiʻi at Mānoa (host), the University of Hawaiʻi at Hilo, and the University of Guam.

The Pacific Islands Climate Adaptation Science Center (PI-CASC, pronounced "pie-cask") is a collaborative partnership between the USGS and a university consortium hosted by the University of Hawaiʻi at Mānoa, with the University of Hawaiʻi at Hilo and the University of Guam, designed to support sustainability and climate adaptation in communities across the Pacific Islands.

The PI-CASC spans the Pacific Basin from the Hawaiian Island archipelago to the US-affiliated islands of the South Pacific (USAPI). The USAPI include the Commonwealth of the Northern Mariana Islands (CNMI); the unincorporated territories of American Sāmoa, Guam, and the Pacific Remote Islands (PRI); and the Freely Associated States (FAS): The Federated States of Micronesia (FSM), the Republic of the Marshall Islands (RMI), and the Republic of Palau. Their vision is to develop science to support policy and management promoting sustainable, interconnected human and ecological communities and species conservation in Hawaiʻi and the Pacific Islands.
