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.
