Carbon dioxide measurements on the Oʻahu Coast

More CO2 in the air means more dissolved in the oceans. But how much and what its affects will be are matters of concern. Read this blog from one of our graduate fellows about her role in investigating CO2 in the waters around Oʻahu.

What can seascape-scale vegetation patterns on coral reefs tell us about reef health?

PI: Elizabeth Madin
Coral reefs worldwide are threatened by changing conditions yet are often remote and hard to monitor. This project will use drone-based imagery to explore how coral “halos” are linked to reef ecosystem health, and whether that health may change over time where protective measures are instituted.

Land-based pollutants on Hawaiian reefs

PI: Megan Donahue
Increased military, agricultural, and residential development contaminates surrounding watersheds that feed into critical coastal ecosystems. This work examines land-based pollutants, such as metals and persistant organics, in coastal ecosystems and reef fish to understand how the pollutants are distributed and transported, with an eye toward better land management decisions.
Podcast #11: DNA Detection

Podcast #11: DNA Detection

Dr. Brian Bowen, Cassie Lyons, and Mykle Hoban capitalize on a new technique of using free-floating environmental DNA sampled from above coral reefs to monitor their health based on the species present.
Podcast #10: Metallic Phish

Podcast #10: Metallic Phish

Dr. Megan Donahue and Eileen Nalley look for traces of land-based, metallic pollutants in tissues of commonly eaten reef fishes and the mechanisms involved in their transport from land to fishes.
Podcast #9: Mesophotic Mapping

Podcast #9: Mesophotic Mapping

Dr. Rob Toonen and Evan Barba explore sediment distribution across the sensitive ecosystems of the mesophotic zone and its connection to land use management decisions.
Podcast #7: Growing Coral

Podcast #7: Growing Coral

Dr. Peter Marko and Claire Lewis are determining the optimal conditions for growth of the coral Pavona variens to aid in restoration efforts of Hawaiian coral reefs.
