|Cold Regions Lake and Landscape Research at the Alaska Science Center focuses on the study of the Arctic and Subarctic landscape, with an emphasis on Alaska. The primary objective of this research program is to gain an understanding of landscape change in the recent (last 50 years) and distant (last 20,000 years) past. This is accomplished through a combination of techniques that include remote sensing, GIS, field surveys, laboratory analyses, and model development. Ultimately, these studies provide information that land and resource managers can use to better inform their decision making process.
Benjamin Jones is the lead investigator at the ASC. He is involved with several interdisciplinary, collaborative research projects in Alaska with a number of Federal, State, and Local agencies as well as researchers in academia. Benjamin Gaglioti is a STEP researcher in the program and currently pursuing a PhD at the University of Alaska Fairbanks.
Project funding is largely provided by the Geographic Analysis and Monitoring (GAM) and the Land Remote Sensing (LRS) programs of the U.S. Geological Survey. Funding is also provided by the Bureau of Land Management and U.S. Fish and Wildlife Service.
*New* An article,"Arctic lakes getting a closer look by scientists", by Ned Rozell about Alaska's "thermokarst" lakes was published in the Anchorage Daily News on May 26. The article describes how USGS Alaska Science Center scientists Benjamin Jones and Benjamin Gaglioti traveled over 800 miles on snow machines installing instruments that will collect data for years to help gain an understanding of change over time on the Arctic landscape.
*New* A manuscript in the May issue of the Journal of Waterway, Port, Coastal, and Ocean Engineering combines the use of field surveys, remote sensing, and model development and validation to better understand patterns and rates of erosion along Alaska's northern coastline.
Benjamin Gaglioti, STEP employee at the ASC and member of the Cold Regions Lake and Landscape Research, was featured in a recent article in the journal Nature highlighting his ground-breaking research that utilized fossil ground squirrel caches to reconstruct the flora and environmental conditions for the Arctic during the last ice age.
