Research Projects

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

Four students pose, smiling, outdoors with a vegetated background

Four students completed projects in climate adaptation science for the 2024 SURF program, investigating the effects of ocean warming on cleaner wrasse behavior, finding the best soil amendments for encouraging native Hawaiian plant regeneration, modeling the optimal pathway for using the RAD framework on Hawaiʻi biomes, and using non-intrusive methods to investigate climate effects of coral growth rates.

2023 SURF Projects

Four students completed projects in climate adaptation science for the 2023 SURF program, investigating how forests vegetation shifts in response to climate change, the connection between climate and humpback whale health, whether added nutrients can improve coral thermal resilience, and sea-level rise impacts to community infrastructure.
