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 United States are being affected by climate change.

Improving Characterizations of Future Wildfire Risk in Alaska
In Alaska, recent research has identified particular areas of the state where both a lack of soil moisture and warming temperatures increase the likelihood of wildfire. While this is an important finding, this previous research did not take into account the important role that melting snow, ice, and frozen ground (permafrost) play in replenshing soil moisture in the spring and summer...
Learning From Recent Snow Droughts to Improve Forecasting of Water Availability for People and Forests
In the dry southwestern United States, snowmelt plays a crucial role as a water source for people, vegetation, and wildlife. However, snow droughts significantly lower snow accumulations, disrupting these critical water supplies for local communities and ecosystems. Despite its large influence on land- and water-resource management, snow drought has only recently been properly defined...
Making an Invisible Resource Visible: Integrating Inland Fisheries into the Sustainable Development Goals
Inland fisheries make up more than 50% of all food fish in the world. Sustainable inland fisheries can support global economic development by providing food for billions and livelihood for millions of people worldwide. However, it can be difficult to quantitatively track and evaluate the services that inland fisheries provide to communities, which ultimately means that the contributions...
Promoting Coastal Resilience and Adaptation in Alaska: Aleutian and Bering Sea Islands Region
In coastal Alaska, changes in snow, ice, and extreme weather events threaten human communities, critical infrastructure, valuable natural resources, and traditional, subsistence hunting and fishing lifestyles. Understanding how changing climate conditions impact Alaska’s coastal ecosystems, and how these changes may be tied to the ability of coastal communities to adapt to changing...
Promoting Coastal Resilience and Adaptation in Alaska: Community Outreach and Engagement
In coastal Alaska, changes in snow, ice, and extreme weather events threaten human communities, critical infrastructure, valuable natural resources, and hunting and fishing livelihoods. Identifying how changing climate conditions impact Alaska’s coastal ecosystems, and how these changes may be tied to the ability of coastal communities to adapt to changing conditions, has been identified...
The Effects of Wildfire on Snow Water Resources under Multiple Climate Conditions
The Colorado and Rio Grande Rivers provide drinking water to millions of people in the Southwest and South Central U.S. Snowmelt accounts for 70% of streamflow in these rivers, meaning that water use downstream is directly impacted by snow accumulation and snowmelt patterns in the mountains. Mountain forests are a critical part of the hydrologic cycle that feeds these rivers, providing...
“Hyperscale” Modeling to Understand and Predict Temperature Changes in Midwest Lakes
Many inland waters across the United States are experiencing warming water temperatures. The impacts of this warming on aquatic ecosystems are significant in many areas, causing problems for fisheries management, as many economically and ecologically important fish species are experiencing range shifts and population declines. Fisheries and natural resource managers need timely and...
Developing Tools for Improved Water Supply Forecasting in the Rio Grande Headwaters
The Rio Grande River is a critical source of freshwater for 13 million people in Colorado, Texas, New Mexico, and Mexico. More than half of the Rio Grande’s streamflow originates as snowmelt in Colorado’s mountains, meaning that changes in the amount of snowmelt can impact the water supply for communities along the entire river. Snowmelt runoff is therefore an important component of...
Enhancing the Capacity of Coastal Wetlands to Adapt to Sea-Level Rise and Coastal Development
Coastal wetlands provide a suite of valuable benefits to people and wildlife, including important habitat, improved water quality, reduced flooding impacts, and protected coastlines. However, in the 21st century accelerated sea-level rise and coastal development are expected to greatly alter coastal landscapes across the globe. The future of coastal wetlands is uncertain, challenging...
How and Why is the Timing and Occurrence of Seasonal Migrants in the Gulf of Maine Changing Due to Climate?
Plants and animals undergo certain recurring life-cycle events, such as migrations between summer and winter habitats or the annual blooming of plants. Known as phenology, the timing of these events is very sensitive to changes in climate (and changes in one species’ phenology can impact entire food webs and ecosystems). Shifts in phenology have been described as a “fingerprint” of the...
Identifying Conservation Objectives for the Gulf Coast Habitats of the Black Skimmer and Gull-billed Tern
Many shorebirds and nearshore waterbirds are of conservation concern across the Gulf of America due to stressors such as human disturbance, predation, and habitat loss and degradation. Conservation and protection of these birds is important for the functioning of healthy ecosystems and for maintaining biodiversity in North America. Consequently, resource managers along the gulf need...
Identifying Critical Thresholds and Tipping Points for Priority Coastal Species in a Changing Future
A large portion of the U.S. population lives in coastal areas along the Atlantic and Gulf coasts and the Caribbean; however, our coasts are also home to many fish, wildlife, and plant species that are important for recreation, tourism, local economies, biodiversity, and healthy coastal ecosystems. Coastal habitats also provide protective ecosystem services to human communities, which are
