Secondary Glacier Network

The Secondary Glacier Network includes six glaciers (Chaney, Grinnell, Stanton, Agassiz, Swiftcurrent, Jackson-Blackfoot Glaciers) that form a north-south transect of approx. 60 km through the region, with Sperry Glacier just south of center. While these glaciers will be monitored less frequently than the benchmark glacier, Sperry, this network will provide data about the variability of...

Benchmark Glacier: Sperry

Sperry Glacier was chosen as the benchmark glacier for the glacier monitoring studies, due to the combination of its topographic characteristics, historic data, and access. Annual mass balance measurements began in 2005. Sperry Glacier joined the long-established USGS Benchmark Glacier Research program in 2013 where common field and analysis methods enable regional comparison and improved...

Glacier Monitoring Studies

The purpose of the CCME's glacier monitoring studies is to systematically monitor changes in Glacier National Park’s namesake glaciers and to determine the causes of changes, assess their ecological and hydrological effects, and predict future changes and effects.

Water, Energy, and Biogeochemical Budgets (WEBB): Trout Lake

USGS initiated the Water, Energy, and Biogeochemical Budgets (WEBB) program to understand the processes controlling water, energy, and biogeochemical fluxes over a range of temporal and spatial scales, and the effects of atmospheric and climatic variables. Trout Lake is one of five small, geographically and ecologically diverse watersheds representing a range of hydrologic and climatic...

Connectivity of Tropical Marine Ecosystems: Understanding Biodiversity and Trophic Relationships in the Virgin Islands and Puerto Rico

Marine reserves and protected areas in the U.S. Virgin Islands and Puerto Rico encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds, but questions remain regarding how effective these areas are at preserving and protecting the habitats and species they encompass. USGS and collaborators address this question by examining the biodiversity and food web...

Potential Impact of Hydrology and Sedimentation Changes to Biodiversity, Dongting Lake, China

Dongting Lake, one of the wetlands that make up the floodplains of China's Yangtze River, is important habitat for migratory waterfowl and other wildlife. However, the re-engineering of the water way and the intensification of agricultural practices has contributed to changes in hydrology and sedimentation. USGS and partners from China are assessing the potential impact of these changes to the...

A Decision Support Tool for Repatriation of Aquatic Fauna: A Case Study Involving the Striped Newt (Notophthalmus perstriatus) at St. Marks National Wildlife Refuge, Florida

The Striped Newt is a small salamander found in xeric habitats (e.g., scrub, sandhill, dry flatwoods) of the lower coastal plain and northern peninsular Florida. Though once considered "common," they are currently a candidate species for federal listing.

GW/SW Interactions

Knowing the interactions of ground water and river water can help reduce the fluctuation of water supplies in alluvial (sediment-deposit) river basins.

To develop general principles of these interactions in order to identify and analyze them, the USGS is reviewing the results of the numerous studies of these interactions in Pacific Northwest basins. The review will describe common...
