Reconnaissance gravity and aeromagnetic surveys of the Antarctic Peninsula By R.G.B. Renner, L.J.S. Sturgeon and S.W. Garrett Get PDF (6 MB).   Two-dimensional models are presented for the crustal structure of the Antarctic Peninsula, a Mesozoic-Cenozoic magmatic arc on the southeast Pacific margin. The models are constrained by measured rock properties. The West Coast Magnetic Anomaly (WCMA) is caused by a zone of mafic plutons which is km wide and over km long. In modelling of Bouguer Cited by:   Another map put together by the British Antarctic Survey and its collaborators in July combined 50 years of magnetic anomaly data collected across the . Between and , the British Antarctic Survey flew a 3-km grid over large parts of the central peninsula (Johnson and Swain, ;Johnson, ) and continues to fly more local surveys.

  The AWI collected a large aeromagnetic dataset as part of the East Antarctic Margin Aeromagnetic and Gravity Experiment (EMAGE) along a km long segment of the East Antarctic coast over western and central DML (Jokat et al., ). The aircraft flight pattern between 18°W and 8°E was extended by two helicopter surveys (~ 20, km) during the / season over . and west extended preliminary coverage and tied with existing surveys. Gravity data was collected on the ground along a central transect of the helicopter survey area. Purpose: From December to January , the CTAM group flew a helicopter and twin-otter aeromagnetic survey and collected ground gravity station data along a profile.

D., Silver E. A., Stoffa P. L. Since the British Antarctic Survey (BAS) has undertaken reconnaissance gravity surveys of the Antarctic Peninsula. Approximately on-rock and about on-snow station values were measured. Continuing climatic, topographical and logistic constraints resulted in an uneven distribution of stations, with a concentration of measurements on the coast and very few on the ice covered spine of .

Interpretation of reconnaissance gravity and aeromagnetic surveys of the Antarctic Peninsula. Journal of Geophysical Resea – Garrett, S. W. & Storey, B. C. Lithospheric extension on the Antarctic Peninsula during Cenozoic subduction.   Aeromagnetic surveys are perhaps the most efficient method of geological reconnaissance in the remote and inhospitable regions of the Antarctic. Over the last 50 years, scientists from many nations have collected magnetic data over and around the continent though often their efforts have been uncoordinated and at times duplication of effort has taken place.
