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.

Estimating the Spatial and Temporal Extent of Snowpack Properties in Complex Terrain: Leveraging Novel Data to Adapt Wildlife and Habitat Management Practices to Climate Change
Snow conditions are changing dramatically in the mountains of the interior Pacific Northwest, including eastern Washington, northern Idaho, and western Montana. These changes can both benefit and hinder a variety of wildlife species. The timing and extent of seasonal snowpacks, in addition to snow depth, density, and hardness, can impact the ability of wildlife to access forage, their...
Evaluating Trends in Streamflow Extremes in the Northeast USA
The goal of this project is to identify statistical trends in observed and simulated maximum, minimum and base (mostly groundwater contribution during low flow months) flows in the Northeast Climate Science Center domain during the 20th and 21st century, assess the temporal (annual and seasonal) and spatial distribution of the trends, and evaluate the impact of warmer climates on the...
Fish Habitat Restoration to Promote Adaptation: Resilience of Sport Fish in Lakes of the Upper Midwest
Many Midwestern lakes are experiencing warming water temperatures as a result of climate change. In general, this change is causing coldwater fish species such as cisco and coolwater species such as walleye to decline. Meanwhile, warmer water species such as largemouth and smallmouth bass are increasing as temperatures warm. However, some fish populations are more vulnerable to these...
Impacts of Sea Level Rise on At-risk Native Freshwater Mussels in Atlantic Coastal Rivers
The Southeastern and Mid-Atlantic regions of the United States contain the greatest biodiversity of native freshwater mussels in the world, but they are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Now they are at even greater risk from the stresses associated with climate change-induced...
Improving the Usability of Modeling Tools for Predicting Coastal Marsh Response to Sea Level Rise
Coastal marshes are vital habitats that protect and support our coastal communities and economies by providing protection from storm surge, filtering pollutants, and providing recreational opportunities. Rising sea levels threaten marshes and jeopardize the benefits they provide to human communities and ecosystems. To preserve these benefits, coastal resource managers need to understand...
Mapping Ecosystem Services for Natural Capital Accounting
The objective of this project is to map the supply of ecosystem services (where natural ecosystems have the capacity to provide a certain product or service that could be of use to people), use of those services (where people or other entities that use the product or service exist), and the condition of ecosystems providing these services over time. The resulting datasets were used to...
Natural and Working Lands Planning in North Carolina
The North Carolina Natural and Working Lands Action Plan, part of the North Carolina Climate Risk Assessment and Resilience Plan, was created in response to Executive Order 80 to identify opportunities for North Carolina’s natural and working lands (NWL), including farms, forests, and wetlands, to sequester carbon, support ecosystem and community resilience, and enhance the state’s...
Online Access to Spatial Datasets for Conservation Planning in the Pacific Northwest
Recent advancements in climate modeling, remote sensing, and ecological science have produced a variety of digital geospatial datasets representing many aspects of climate-change ecology that can be applied to conservation and natural-resource management in the face of climate change. The ever increasing body of climate-ecology spatial datasets provides opportunities for natural-resource...
Organizing and Synthesizing Ogallala Aquifer Data to Facilitate Research and Resource Management
The Ogallala Aquifer lies beneath 111 million acres of land in Wyoming, South Dakota, Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico. The aquifer provides water for approximately 1.9 million people and has been instrumental in the development of the robust agriculture economy of the Great Plains region. It is also vitally important to the ecology of the region, serving as a...
The Future Resiliency of Mangrove Forests to Sea-Level Rise in the Western Pacific: Initiating a National Assessment Approach
Sea-level rise will eventually flood and kill many coastal mangrove trees. The loss of mangrove forests will strongly affect human populations on isolated western Pacific islands as they rely heavily on mangroves for food, such as fish, shrimp, and crabs; building materials; and fire wood. Mangroves also shelter coastal communities from the impacts of tsunamis and cyclones, are home to...
The Impact of Climate Change and Sea-Level Rise on Future Flooding of Coastal Parks and Refuges in Hawaiʻi and the U.S. Affiliated Pacific Islands
The Pacific Ocean is home to a number of low-lying, coastal national parks and wildlife refuges. These public lands are situated on coral reef-lined islands that are susceptible to inundation from sea-level rise and flooding during storms. Because of their low-lying nature and limited availability of space, ecosystems, cultural resources, and infrastructure on these islands are...
The Impacts of Climate Change and Water Supply Management on Fish in the Colorado River
The Colorado River and its major tributaries provide a crucial water supply for more than 40 million people in the American Southwest and in California. This water supply is primarily used in irrigated agriculture but also provides essential drinking water to many large metropolitan areas. Hydropower is also produced at many of the large dams on the river. River flows have declined...
