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.

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...
Ghuts, Grit, and Gills: Aquatic Data Synthesis for Climate Adaptation in the US Virgin Islands
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...
Identifying the Environmental Limits of Aquatic Species in Prairie Streams to Build Climate Resilience
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...
Impacts to Ecosystems and Fisheries in Northwest Alaska from “Rusting Rivers”
Project Overview In Northwest Alaska, “rusting rivers” are becoming increasingly apparent as climate change causes ancient spring seeps to re-emerge after permafrost melts. While they have become more common over the past few years, very little is understood about their impacts on stream food webs. Researchers supported by this Alaska CASC project will bridge the knowledge gap by...
Improving Land Change Models for Climate Adaptation, Urban Development, and Conservation Action Across the US Caribbean
Project Overview 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...
Leveraging Existing Data to Assess the Vulnerability of Native Salmonid Populations in the Greater Yellowstone Area
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...
Linking Research and Stakeholder Engagement for Effective Wetland Conservation in a Changing Climate
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...
Mapping Community Experiences and Concerns Related to Drying Lakes in Arid Climates
Declining water levels in the Great Salt Lake are part of a larger trend of decreasing water availability in the Southwestern U.S. that presents significant challenges for people, animals, and ecosystems. One challenge is that as some lakes dry, newly exposed sediment containing heavy metals can become toxic dust that blows into populated areas. Increased air pollution and other effects...
Mapping Habitat Connectivity and Climate Refugia in Headwater Ecosystems to Support Amphibian Conservation
Project Overview Forests in the Pacific Northwest support an extensive network of headwater streams and critical habitats for over 50 amphibian species, but face challenges from historical resource extraction, forest management, and climate change. Researchers supported by this Northwest CASC project will identify and map climate refugia to guide conservation strategies for at-risk...
Nature-Based Solutions for Flood Risk Reduction and Community Resilience in the Upper Mississippi River Basin
Project Overview Climate risks, including floods and heatwaves, impact communities in the Upper Mississippi River Basin, but gaps in data, policy, and collaboration in the region can hinder effective climate adaptation. Researchers supported by this Midwest CASC project will work with communities to identify flood-vulnerable areas, evaluate various nature-based solutions, and develop a...
Research to Action for Yukon River Salmon: Adapting to Climatic, Food-Web, and Habitat Changes
Project Overview Salmon populations in the Yukon River Basin have plummeted to historic lows, disrupting fisheries, fueling conflicts, and impacting communities that have relied on salmon for generations. Researchers supported by this Alaska CASC project will combine traditional knowledge, field data, and modeling to identify the key drivers of salmon decline and create tools to guide...
