Processed line aerogravity data over Northern Palmer Land, Antarctic Peninsula (2002/03 season)
GB/NERC/BAS/PDC/01359

Summary

Abstract:
Over 20,000 km of new aerogravity data were acquired over Palmer Land during the 2002-2003 Antarctic campaign. Profile lines were oriented E-W with N-S tie lines. Line spacing was 5 km, tie lines were 25 km apart and nominal flight altitude was 2800 m. Differential, carrier phase, kinematic GPS processing methods provided the vertical and horizontal accelerations, which dominate the raw aerogravity signal. Levelled airborne gravity data have mean accuracies of 3 mGal.

We present here the processed line aerogravity data collected using Lacoste and Romberg air-sea gravity meter S83.
Data are provided as XYZ ASCII line data.
