A major achievement in research supported by the Kluane Lake Research Station was the recovery, in 2001–02, of a suite of cores from the icefields of the central St. Elias Mountains, Yukon, by teams of researchers from Canada, the United States, and Japan. This project led to the development of...
The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...
The high accumulation rate and negligible amount of melt at Eclipse Icefield (3017 m) in the Saint Elias Range of Yukon, Canada, allows for the preservation of a high-resolution isotopic and glaciochemical records valuable for reconstruction of climatic variables. Each of the three Eclipse ice cores have a well-constrained depth–age...
The use of radioactive isotopes as tracers in biological systems
has become widespread since the close of World War II. Proper
use of radiotracers requires a fundamental understanding of the physical
nature of radioactivity, the characteristics of ionizing radiation,
and the various methods available for measuring radioactivity.
More importantly, the...
