A new study today found a sharp rise in the melt rate of three key American glaciers … Introduction. The distribution of snow cover over the basin and the late-winter snow balance, m (s), were measured on May 12, 1965 (pl.

Winter snow accumulation and summer snow and ice ablation were measured at South Cascade Glacier, Washington, to estimate glacier mass-balance quantities for balance year 2003. Federal government websites often end in .gov or .mil. Before sharing sensitive information, make sure you’re on a federal government site. Available data for this site . Regional physical and climatic setting Geology Glaciers store precipitation as ice, transport it away from where it was deposited, then release it as water, sometimes centuries or millennia later. The core of this collection is composed of mass balance data from the USGS Benchmark Glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. This glacier has been classified as one of the ‘reference glaciers’ by the World Glacier Monitoring Service because it has received continuous long-term observations dating back to the year 1952/53.

U.S. Geological Survey researchers conducted time-series ground-penetrating radar (GPR) surveys with a Sensors and Software 500-MHz Pulse Ekko Pro system. TABLE 4.—Snow, ice, and water balances, South Cascade Glacier, 1966 hydrologic and balance years [Parameter values and errors in meters except where indicated, Date: Hydrologic year, Oct. 1, 1965 (t 0), to Sept. 30, 1966 (t 1)] Since 1966 when the USGS began collecting annual mass balance data, the mass of Gulkana Glacier has been decreasing by 0.4 meters per year on average. In addition to mass-balance measurements, which date to 1958, numerous hydrological investigations have been carried out during the last three decades, and repeated ice-thickness determinations have been made using a variety of techniques. Water, Ice, Meteorological, and Speed Measurements at South Cascade Glacier, Washington, 1999 Balance Year By Robert M. Krimmel. The 2003 glacier-average maximum winter snow balance was 2.66 meters water equivalent, which was about equal to the average of such balances for the glacier since balance year 1959. South Cascade Glacier is a temperate mountain glacier located in the Cascade Mountains, Washington. Geological Survey Professional Paper 715—B.

Mount Rainier, Washington, at 14,410 feet (4,393 meters), the highest peak in the Cascade Range, is a dormant volcano whose glacier ice cover exceeds that of any other mountain in the conterminous United States. ABSTRACT. Mount Rainier has approximately 26 glaciers. A composite image showing South Cascade glacier in Washington state (year 2000, left, 2006, right). Location in Skagit County, Washington. U.S. Geological Survey Professional Paper 715-A, 23. Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Additional Resources.
