Dynamics and Climatic Response of the Taylor Glacier System Funded by the National Science Foundation, Office of Polar Programs
|
| Taylor Glacier drains the Taylor Dome region of the East Antarctic Ice Sheet and terminates in Taylor Valley, one of the Dry Valleys of Victoria Land. It provides a crucial and unique link between two intensively studied Antarctic environments: the Taylor Dome, from which a 130 kyr ice core paleoclimate record has recently been extracted, and the Dry Valleys, a pivotal Long-Term Ecological Research site and a focus of research on geomorphology and glacial geology. We are involved in a project to understand how Taylor Glacier flows and responds to climate changes. During 2002/03 we began a two-year field campaign to survey ice motion and bed topography along 22 transverse lines. We will present radar-sounding results from our 2002/03 season, combined with those from previous airborne and ground-based surveys. Travel time-depth migration of the transverse profiles support reanalysis of earlier flux calculations of Robinson (J. Glac., 1984) as well as refine the image of dramatically undulating bed topography reported by Calkin (J. Glac., 1974). |
