Understanding Sediment Transport to Coastal Waters and Coral Reefs in West Maui

Coral ecosystems of West Maui support a vibrant tourism industry and provide tangible economic benefits to the community. Hawaiian nearshore reefs generate about $800 million in annual revenue, not including the ecosystem services they provide - such as critical habitat for diverse fish species and buffering coasts from storm surges. The Hawaiian economy depends on healthy coral...

Assessing Permafrost Changes and Related Impacts on Alaskan Infrastructure and Communities

Permafrost is a layer of perennially frozen soil that primarily exists in and around the Arctic and Antarctic regions of the world. While a shallow near-surface soil layer (called active layer) thaws during the summer and re-freezes in the winter, the underlying permafrost remains perennially frozen, often underlying buildings, roads, and other infrastructure. As warmer temperatures...

Changing Hawaiian Seascapes and Their Management Implications

Hawaiian shorelines and near-shore waters have long been used for cultural activities, food gathering and fishing, and recreation. As seascapes are physically altered by changing climate, the ways in which people experience these environments will likely change as well. Local perspectives of how seascapes are changing over time can help managers better understand and manage these areas...

Effects of Sea-Level Rise and Extreme Storms on California Coastal Habitats: Part 2

In California, the near-shore area where the ocean meets the land is a highly productive yet sensitive region that supports a wealth of wildlife, including several native bird species. These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and...

Forecasting Beach Loss from Sea-Level Rise on the Island of Kauaʻi

The beaches of the Hawaiian Islands attract nearly 9 million visitors each year, who inject around $15.6 billion into the state’s economy and support almost 200,000 jobs. Beyond their economic importance, Hawaiian beaches are also culturally and ecologically valuable. However, climate change driven sea-level rise is causing many beaches to disappear, endangering property, infrastructure...

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...

Establishing a Foundation for Understanding Climate Change Impacts on Coastal Wetland Ecosystems

Coastal wetlands are one of the most economically valuable ecosystems in the world. In the United States, the ecosystem services provided by wetlands are worth billions of dollars and include flood protection, erosion control, seafood, water quality enhancement, carbon storage, recreation, and wildlife habitat. Unfortunately, these ecosystems are also highly sensitive to changing climate

Informing Conservation Management Decision-Making at Coastal National Wildlife Refuges

Coastal National Wildlife Refuges (NWRs) provide a myriad of beneficial services, including buffering storm surge, improving water quality, supporting commercial fisheries, and providing habitat for imperiled wildlife and plants. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more...

Informing the Identification of High-Priority Lands for the Everglades Headwaters National Wildlife Refuge Considering Future Climate and Urbanization

Reserve design is a process that must address many ecological, social, and political factors to successfully identify parcels of land in need of protection to sustain wildlife populations and other natural resources. Making land acquisition choices for a large, terrestrial protected area is difficult because it occurs over a long timeframe and may involve consideration of future...

Projections of Future Coral Reef Communities in DOI-Managed Coastal Areas in the Hawaiian Islands

The conditions of coral reefs in the Hawaiian Islands are predicted to decline significantly from climate change over the next 100 years. To better prepare for the impacts of climate change on Hawaiian reefs, the research team uses a system of models to simulate ocean waves and circulation, rainfall and storm run-off, and coral reef community dynamics through the year 2100. These models...

Structured Decision-Making as a Tool for Coastal Restoration: A Case Study on Ship Island, Mississippi

Barrier islands protect mainland areas from storm surge, but can erode over time and require restoration. Ship Island, a barrier island off the coast of Mississippi, provides an example of this: the island was battered by Hurricane Camille in 1969 and split into two separate islands. As part of the Mississippi Coastal Improvements Program, the U.S. Army Corps of Engineers plans to use

Valuing Climate Change Impacts on Coral Reef Ecosystem Services

Coral reefs provide numerous ecosystem goods and services critical to human well-being (e.g., protection from storms and floods, food, income, recreation, and cultural practices), but they are threatened by growing human pressures and climate change.
