RESEARCH PROJECTS

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

Five SURF students pose in front of a steep vegetated slope

2022 SURF Projects

Five students completed projects in climate adaptation science for the 2022 SURF program, investigating fire-prone invasive grasses, spillover effects of Marine Protected Areas, shifts in estuarine fish biodiversity, optimal regeneration conditions for koa, and effects of marine warming on different phytoplankton strains.
