Gamburtsev Antarctic Mountains Seismic Experiment (GAMSEIS)
As a part of the larger AGAP project we propose to deploy broadband seismometers to image the lithospheric structure of the Gamburtsev Subglacial Mountains to answer
- What is the mechanism driving uplift of the Gamburtsev Mountains?
- What role did they play in the formation of the East Antarctic Ice Sheet?
To address these questions, we have designed a seismic experiment that will enable us to image details of the crust and upper mantle structure across the Gamburtsev Subglacial Mountains. This seismic experiment consist of three elements:
- A 900 km linear array of 12 broadband seismic stations extending from Array 1 of the TAMSEIS deployment;
- An intersecting 550 km linear array of 7 broadband seismic stations crossing the Gamburtsev Mountains at an angle of ~115 degrees to the longer line;
- 8 broadband stations not on a line to improve 3-D resolution of the Gamburtsev Mountains
In addition to the seismic studies, airborne geophysical surveys and drilling are planned. This project is a major initiative of the International Polar Year and is part cooperative effort by several nations to explore one of the least visited and most poorly understood regions on earth.
