Magnetic survey in Ongul Strait, Lutzow-Holm Bay, East Antarctica

Abstract

Measurements of total intensity of the geomagnetic field were carried out during the 35th Japanese Antarctic Research Expedition (JARE-35) in Ongul Strait, Lutzow-Holm Bay, East Antarctica. N-S and NNW-SSE striking magnetic anomalies are observed in Ongul Strait. Negative magnetic anomalies are dominant except for the southwestern part of Ongul Strait. Magnetic anomalies vary from about-100nT to 80nT.
