Ice thickness and related data over central Marie Byrd Land, West Antarctica (GIMBLE.GR2HI2)
Abstract: GIMBLE was proposed as the first systematic aerogeophysical investigation of the subglacial massif underlying central Marie Byrd Land. Aerogeophysically configured Baslers conducted 14 flights from Byrd Surface Camp and WAIS Divide Camp over two field seasons (January 2013 and December 201...

Level 2 data represent geolocated geophysical properties (e.g ice thickness), derived from Level 1B measurements (e.g. radar echo delay).

Georefering data is contained in .met files. GIMBLE.GR2HI2 contains line based data (in ASCII space delimited txt files) relating to ice thickness, bed elevation and bed reflectivity, extracted from 1-D focused radargrams by semiautomatic interpretation. Data was acquired using HiCARS2 in ICP5, and MARFA in ICP6. Some data loss occurred in ICP6 (in particular F10,F11, and F14), limiting the lines that were focused. Data reduction was led by D.
