In January, we traveled from Christchurch to Twizel, a town southwest of Lake Pukaki. The Role of Ocean-Atmosphere reorganizations in glacial cycles. From our base in Twizel, we spent a month in the region west of Lake Pukaki mapping the glacial landforms deposited by the former Pukaki Glacier. He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.
We will use this comparison to assess the reaction of the Antarctic Ice Sheet to the warming of the last termination (this work is explained in my other two field reports on Hatherton and Darwin Glaciers, Antarctica).
Uranium is the heaviest and last naturally occurring element in the periodic table.
The periodic table is a chart that shows how chemical elements are related to each other.
Wiens has a Ph D in Physics, with a minor in Geology.
