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.

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 maps abou

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 fish stoc

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, local fishe

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 communities.

Improving Land Change Models for Climate Adaptation, Urban Development, and Conservation Action Across the US Caribbean

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

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 shorebirds).

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 of drying

A Decision-Support Tool for Invasive Plant Management Under Fluctuating Great Lakes Water Levels

Water levels in the Great Lakes are fluctuating in ways that we have not seen in the past, with both historically low- and high-water levels occurring in the last decade. Expectations are that larger and more frequent water-level fluctuations will occur in response to climate change. The increased variability in lake levels has implications for the management of invasive plants found in the coasta

A Fresh Set of Tools: New Information for Managing Fisheries During Changes in River Discharge

The Bonnet Carré spillway (BCS) is a flood-control structure along the Lower Mississippi River designed to prevent flooding in the city of New Orleans by diverting excess water into the nearby Lake Pontchartrain estuary. Alarmingly, the BCS was opened as many times over the past decade (2011–2020) as it had been over the six prior decades combined (1951–2010), with devastating effects on the estua
