Water, Coasts and Ice

Atmospheric nitrogen deposition, climate change and recreation are rapidly altering high elevation ecosystems. This project will evaluate long-term biogeochemical, hydrological, and ecological trends in Rocky Mountain National Park to understand the causes and rates of change in alpine and subalpine waters, soils, and vegetation. Policy makers and resource managers of high-elevation, protected...

The sandbar willow of the Klamath River is used within the Karuk Tribe’s ongoing cultural practices of basketweaving. The willow has been threatened by intensifying fire and dams, but restoration and the recent historical dam removals provide an opportunity to increase the quantity, quality, and access to this important resource. Researchers supported by this Southwest CASC project will study how

Rising sea levels and frequent intense storms are rapidly changing Northeastern US coastal landscapes and threatening the vital ecosystem services they provide. Researchers supported by this Northeast CASC project will use landscape models, co-developed with coastal managers and tribal managers, to predict expected coastal changes for different environments (e.g., beaches, wetlands, rocky headland

Wetlands along the Gulf Coast are crucial for reducing hurricane-induced flooding and as habitat for diverse wildlife, but are threatened by rising sea levels, climate change, and coastal development. Using remote sensing data, future climate data, and numerical models, researchers from this South Central CASC-supported project will collaborate with local expert groups to create data and maps abou

Current stormwater management infrastructure and strategies in the northeastern US are built around historical weather data and not the weather that is expected with climate change, like more frequent extreme rainfall. This matters because stormwater can introduce pollution to streams and can cause flooding. Researchers supported by this Northeast CASC project will combine climate data, stormwater

Project Overview Declining winter ice cover in the Great Lakes can affect how winds and waves influence coldwater fish reproduction on reefs, as ice cover may shield fish from these forces. Researchers supported by this Midwest CASC project will measure water movement and ice cover in Lake Erie to model future scenarios, helping fishery managers in the region make habitat restoration and fish stoc

Coastal marshes in the Gulf of Mexico host diverse ecological communities and hold Native American cultural artifacts within shell mounds (middens). However, both are vulnerable to erosion and submergence due to rising sea levels and more frequent severe storms. Researchers supported by this Southeast CASC project will develop a risk-assessment tool to evaluate the vulnerability of cultural sites

The US Virgin Islands are vulnerable to sea level rise, intense storms, and unpredictable rainfall brought by climate change. These changes influence the health of freshwater streams (known as “ghuts”), sedimentation, erosion and water quality (“grit”), as well as aquatic communities and ecosystems (“gills”) that are unique to the islands and important for indigenous peoples’ heritage, local fishe

Project Overview Climate change and human activities are threatening many sensitive aquatic species in prairie streams across the Great Plains region. Researchers supported by this North Central CASC project will combine and analyze data collected independently by Great Plains states to identify thresholds of environmental change that may lead to species loss and changes in aquatic communities. Th

Climate and economic stressors are causing large numbers of people to emigrate from Puerto Rico and the U.S. Virgin Islands, even while new development continues. To provide a tool to help managers and policymakers make informed decisions about development and conservation, researchers for this Southeast CASC-supported project will co-produce a land change model that can simulate future scenarios

Project Overview: Native Yellowstone cutthroat trout and mountain whitefish in the Greater Yellowstone Ecosystem (GYA) are ecologically and socio-economically important species, but are threatened by drought, rising water temperatures, habitat loss, and non-native species. Researchers supported by this North Central CASC project will use climate data and extensive population records to assess the

Climate change threatens many functions of wetlands and habitat connectivity for migratory shorebirds who use wetlands across the Southern Great Plains. Researchers supported by this South Central CASC project will survey stakeholders in the region, project climate impacts on wetland-dependent birds, and create tools for conservation planning (e.g., ranking wetland importance to shorebirds).
