Development of an Environmental Assessment and Eradication Plan to Remove Tilapia from Ponds and Wetlands in National Parks on the Island of Hawai’i

Mozambique tilapia, a highly invasive non-native fish of the family Cichlidae, were discovered in a wetland in Kaloko-Honokohau National Historical Park on the Big Island of Hawai'i. As the U.S. National Park Service works to restore the natural communities and functions of wetland ecosystems on the island, the eradication of the tilapia population is considered necessary to fully achieve...

Understanding Coastal Change

Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

Geologic Hazards and Catastrophic Events

We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.

Assessing the Sustainability of Culturally Important Marine Sites in Guam and CNMI

This project was designed to use climate models to produce projections of changes in sea temperatures and ocean chemistry for coastal marine areas in Micronesia as well as reports that describe the outlook of culturally important marine sites in Guam and CNMI. The projections and maps were expected show what the current state of climate science suggests the future holds for marine areas in...

Coral Reef Resilience to Climate Change in the Commonwealth of the Northern Mariana Islands

Coral reefs are sometimes called “rainforests of the sea” because of their immense biological diversity and economic value. While coral reefs are sensitive to changes in their environment such as altered temperature or pollution, some reefs are more resilient, or able to recover from disturbance more quickly, than others. The overarching objective of this project was to gather information on...

Data from coastal circulation and water-column properties in the National Park of American Samoa, February-July 2015

The continuous measurements of waves, currents, tides, and water-column properties from instrument deployments, coupled with available meteorological measurements of wind and rainfall, provide information on nearshore circulation and the variability in these hydrodynamic properties. These data will complement ongoing and future water quality efforts...

Dataset: Forest growth in and around an ungulate enclosure on Northern Guam, 2005-2011

On an island largely devoid of native vertebrate seed dispersers, we monitored forest succession for seven years following ungulate exclusion from a 5-hectare area and adjacent plots with ungulates still present. The study site was in northern Guam on Andersen Air Force Base (13°37’N, 144°51’E) and situated on a coralline limestone plateau. We established 22 plot
