Climate Research and Development Program

Glaciers

Glaciers store water as ice, transport it from where it fell as precipitation, and release it to streams and rivers years to millennia later. The Climate R&D Program focuses on documenting changes in glacier mass balance (how much water they contain), understanding magnitudes and drivers of change, and evaluating the impacts on freshwater availability, sea-level rise, and downstream communities.

Past Perspectives of Water in the West

In the intermountain west, seasonal precipitation extremes, combined with population growth, are creating new challenges for the management of water resources, ecosystems, and geologic hazards. This research contributes a comprehensive long-term context for a deeper understanding of past hydrologic variability, including the magnitude and frequency of drought and flood extremes and ecosystem...

Biogeochemistry of glaciers

Significant change to the Arctic and sub-arctic water cycle is underway, impacting hydrologic and biogeochemical fluxes.  In southcentral Alaska, glacier mass loss, changes to precipitation (including the rain/snow fraction), thawing ground ice, and vegetation encroachment will change both magnitude and timing of water and solute fluxes downstream.  Although altered fluxes of limiting...

Sea Level and Storm Hazards: Past and Present

Sea level and Storm Hazards: Past and Present is a multidisciplinary study of past changes in sea level. Prehistoric shorelines can be used as a baseline for current and future sea level changes under warmer-than-present climate. Emphasis is placed on looking at sea levels during warm periods of the last 500,000 years as well as how base level changes increase the risk of coastal inundation...

USGS Benchmark Glacier Project

Scientists with the USGS Benchmark Glacier Project study the process and impacts of glacier change, including sea-level rise, water resources, environmental hazards and ecosystem links. At the core of this research are mass balance measurements at five glaciers in the United States. Since the 1960s, these glaciers have been studied using direct observations of glaciers and meteorology. The...

Holocene Hydroclimate of Western North America

The objectives of this project are to reconstruct detailed histories of Holocene hydroclimate and corresponding environmental change from geological archives such as lake sediment, peat, and wood to more fully understand past, ongoing, and future change and its impacts.

Terrestrial Records of Holocene Climate Change: Fire, climate and humans

Large wildfires have raged across the western Americas in the past decade including the Las Conchas, New Mexico fire that burned 44,000 acres in a single day in 2011 (Orem and Pelletier, 2015, Geomorphology 232: 224-238, and references therein), the 2016 Fort McMurray, Alberta fire that required evacuating an entire city, and the 2015 Alaskan fire season that burned more than 5 million acres (...
