Description
Summary:The 40th Japanese Antarctic Research Expedition (JARE-40) conducted field operations on geology and geomorphology in the Amundsen Bay region, Enderby Land, for 34 days from December 21,1998 to January 23,1999. This was a part of the 5-year SEAL (Structure and Evolution of East Antarctic Lithosphere) project, and two helicopters were installed for field support. Geological and geomorphological teams established base camps at Tonagh Island and Mt. Riiser-Larsen, respectively, and tried to conduct surveys in western Enderby Land. At the early stage of the operation, an unexpected gusty wind destroyed one of the helicopters at Tonagh Island, and planned surveys have not been completed. This report gives details of the logistics including planning, preparation and results.
