Research Locations:  Taylor Glacier

Project Description:
The objective of this project is to continue the use of the Taylor Glacier ice ablation area for paleoenvironmental studies and to expand the understanding of the surface-ice stratigraphy. Researchers will examine the methane record, cosmogenic 14C, variations of CO2, nitrous oxide and their isotopes, and will continue age mapping of the ice. In addition, they will conduct pilot studies of new tracers, filter meltwater for extraterrestrial dust and organic material, and perform on-site methane isotopic analyses.

Field Season Overview:
A science team of eight persons will camp on Taylor Glacier for two months. They will drill at numerous locations on the glacier to depths up to 70 meters. Large-diameter cores will be extracted and melted on-site, from which the released air will be captured and transported to home institutions for further analysis. In addition, numerous smaller-diameter core will be drilled at various locations on the glacier. A small quantity of ice will also be shipped to the home institution.

Deploying Team Members:

  • Daniel Baggenstos
  • Thomas Bauska
  • Michael Dyonisius
  • Benjamin Hmiel
  • Chandra Llewellyn
  • Avery Palardy
  • Vasilii Petrenko (PI)
