Water, Coasts and Ice
Water, Coasts and Ice
Warming temperatures and shifting weather patterns are causing major changes in water and ice availability, sea levels, and aquatic nutrient cycles across the country. CASC-supported scientists are examining how water, ice, and coastal ecosystems and communities across the country are being affected by climate change. Explore our science on this topic below.

Forecasting Tools to Inform the Management of Native Fishes and Their Habitats in a Drought Sensitive Terminal Lake System
Project Overview Terminal lake systems, water sources that are confined to streams, wetlands, and seasonal lakes that do not flow into the ocean, are greatly impacted by climate effects such as drought, reduced snowpack and increased wildfire activity. As a result, managers are faced with a lack of resources to study these aquatic habitats and the residing native fish. Researchers...
From Water to Life: Impact of Climate Warming on Potential Wetland and First Foods Habitat in Traditional Use Areas of The Klamath Tribes
Project Overview First foods are integral components of the culture, spirituality, medicine, well-being, and health of the Klamath people. Throughout the Klamath Basin, climate change has substantially impacted the seasonality, abundance, and quality of first foods and other culturally important resources. These impacts compound with long-term challenges to food security and food...
Effects of global change on alpine and subalpine ecosystems
Atmospheric nitrogen deposition, changing environmental patterns, 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. Resource managers of high-elevation, protected...
A New Tool for Monitoring Vegetation Water Use and Efficiency to Support Sustainable Agroecosystem Management
Oklahoma and Texas are facing significant future water shortages that threaten farming and ranching communities. Though conservation-based management practices are being implemented across the states, there are inadequate tools for monitoring vegetation water use efficiency in real time. Researchers supported by this South Central CASC project will develop a web-based tool using high...
After the Dams: Fire Impacts and Restoration Opportunities for a Culturally Important Klamath River Willow
Project Overview 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...
Building community-based monitoring partnerships between rural schools and wildlife refuges in Alaska
Project Overview In Alaska, winters are becoming shorter and more unpredictable, leading to changes in lake and river ice, impacting access to hunting grounds, fuel wood transportation and recreation for local communities. Researchers supported by this Alaska CASC project will revitalize and modernize a freshwater ice observation network with a youth-centric partnership that teams...
Climate-Driven Changes to Forested Wetland Inundation Dynamics: Implications for Frogs and Toads
Project Overview Wetlands in forested areas of the Upper Midwest provide vital habitat for amphibians, but changing patterns of drying under climate change can disrupt species reproduction and growth. Researchers supported by this Midwest CASC project will use water depth sensor data, machine learning models, and long-term amphibian surveys to predict wet and dry periods for wetlands...
Coastal Responses to Sea-Level Rise: Landscape-Scale Understanding in an Uncertain Future
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...
Coastal Wetland Dynamics and Impacts on Hurricane Flood Risk along the Texas Gulf Coast in a Changing Climate
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...
Designing Climate-Resilient Stormwater Management in Northeastern US Cities to Support Stream Ecosystems
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...
Does Less Ice Cover Lead to More Turbulent Overwinter Conditions on Great Lakes Fish Spawning Reefs?
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...
Evaluating the Vulnerability of Indigenous Shell Middens and Marsh Habitat Diversity to Sea Level Rise
Project Overview Coastal marshes in the Gulf of America 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...
