We present the first high-resolution (sub-annual) dust particle data set from West Antarctica, developed from the West Antarctic Ice Sheet (WAIS) Divide deep ice core (79.468° S, 112.086° W), and use it to reconstruct changes in atmospheric circula

Publikováno v: Global Biogeochemical Cycles. 35
The subarctic Pacific Ocean and Bering Sea comprise the second-largest high nitrate, low chlorophyll region in the world, where primary production is limited by the availability of iron (Fe). To es...

The Volcanic Explosivity Index (VEI) 5 eruption of the Puyehue-Cordon Caulle volcanic complex (PCC) in central Chile, which began 4 June 2011, provides a rare opportunity to assess the rapid transport and deposition of sulfate and ash from a mid-lati

Integrating Scientific Argumentation to Improve Undergraduate Writing and Learning in a Global Environmental Change Course
Autor: B. G. Koffman, Karl J. Kreutz, Kim Trenbath
Publikováno v: Journal of Geoscience Education. 65:231-239
We present a strategy for using scientific argumentation in an early undergraduate laboratory course to teach disciplinary writing practices and to promote critical thinking, knowledge transformation, and understanding of the scientific method. The a
