Field Season Overview
The AGAP project will use an aerogeophysically instrumented BAS Twin Otter aircraft to survey the northern flanks of the Gamburtsev Subglacial Mountains. The goal will be to fly approximately 71 geophysical flights primarily between AGAP-N and Dome A. The approximately 290 survey hours of BAS Twin Otter flying will complement the 61 USAP Twin Otter flights 330 survey hours primarily on the southern flank of the Gamburtsev Subglacial Mountains between Dome A and AGAP-S. The program will require use of the instrumented BAS Twin Otter to fly from November 5 - through January 19. The aerogeophysical instrumentation will be installed in McMurdo, while the primary base of BAS flight operations will be the AGAP-N camp after transiting via South Pole where we will acclimatise. A total of 4 BAS-AGAP staff comprising of 3 scientists & 1 aerogeophysics engineer will be deployed through this project. Two survey pilots, 1 airmech will, 1 BAS GA and 3 Australian camp staff will support the BAS aerogeophysics. BAS Twin Otter VP-FAZ with 1 pilot and 1 airmech will support AGAP North for part of the season, along with the AWI Basler and Australian Casa aircraft.

Research Objectives
The AGAP project is a major IPY program resulting from a partnership between 6 nations targeted at the first systematic exploration of the Gamburtsev Subglacial Mountains Province of East Antarctica. This mountain range, the size of the European Alps rises 14,000 feet above the surrounding terrain but is completely hidden by the East Antarctic Ice Sheet. The tectonic mechanisms responsible for this major uplifted region are virtually unknown. The Gamburtsev Subglacial Province was the nucleation point for the modern East Antarctic ice sheet and likely contains some of the oldest ice remaining on the planet, an important target for future ice coring. On the flanks of the Gamburtsev Subglacial Mountains rest the largest subglacial lakes - lakes that in some cases appear to be triggering the onset of fast flowing ice streams. The objectives of the AGAP program are to acquire key data sets for understanding the origin of the Gamburtsev Subglacial Mountains, define the history of the East Antarctic ice sheet, identify the oldest ice containing the longest climatic record of atmospheric gases and examine the role of subglacial lakes in ice sheet stability. The aerogeophysical observation of ice thickness, ice sheet structure, gravity and magnetics will provide crucial new insights into the Antarctic ice sheet, and when integrated with the results of the GAMSEIS results will offer the first insights into the origin of the Gamburtsev Subglacial Mountains. By utilising the BAS aerogeophysical platform we plan to realise the first geophysical transect across East Antarctica.

My Part in the large picture - or a small cog in a larger machine
My role in this huge project will be to install the survey equipment into the British Antarctic Surveys Twin Otter VP-FBL this includes ice penetrating radar, magnetics and gravity systems. In McMurdo test flights will be flown so we can check and optimise the systems for the season. We shall then deploy to the field via South Pole for acclimatisation after we will operate out of AGAP North field camp. For a period of a month and half I will help operate the science equipment as the aircraft flies over the Dome-A area. I will be responsible for keeping the equipment serviceable and carryout repairs with my limited selection of parts carefully packed at Cambridge.
This is a unique chance to challenge myself to the extreme and be part of some big in a never before undertaken endeavor in the pursuit of world-class science with our international teammates.
