RESEARCH PROJECTS

PI-CASC supports research that generates actionable climate science within several key focus areas defined by regional stakeholder needs.

2025 SURF Projects

2025 SURF Projects

Six students completed projects in climate adaptation science for the 2025 SURF program, investigating ways to protect at-risk corals, conducting case studies in air temperature changes and water resource management solutions, and using high tech tools to catalog ʻopihi and zooplankton under varying conditions.
