FIELD CAMPAIGN
In-situ ice thickness survey
PI: Jackie Richter-Menge
Co-I: Bruce Elder
Aims
- Provide in-situ cal-val data for satellite, air-borne and underwater ice thickness surveys.
- Identify the modes of ice thickness, and determine shape of ice thickness distribution, within the 1km region.
First Task
Lay out survey lines If we have a liason between Navy and NSF camps, the liason will be charged with obtaining bearing from camp of the submarine tracks, and adjus ting for camp rotation, lay out survey lines along the first kilometer of these tracks. Possible candidates for this task: Peter Wadhams, Jackie Richter-Menge, Pablo Clemente-Colon. Whippy flags and stakes will be used to mark exact survey lines. Coloured bin (trash) bags will be placed along the left hand side of the line to aid aircraft navigation.
Survey Method
Survey tasks:- EM-transects, record data every 4m
- Drill hole every 100m recording freeboard, total thickness and snow depth.
- Snow depth every 4m.
- GPR transect

Equipment
- EM-31
- GPR
- 2inch ice auger with 4 flights, 2 cutting bits, hand brace, drill adaptor.
- Generator
- Electric drill to drive auger
- Sled for GPR
- 100 red and green bin bags
