Marine geophysical observations (Ocean Bottomo Pressure Gauge data) in JARE60

Sea-surface gravity and geomagnetic measurements are conducted on board the R/V Shirase in the Southern Ocean. Sea bottom pressure is monitored with a pressure gauge installed and recovered every summer on the sea bottom about 4000 meter deep in the Southern Ocean.科研考察船白濑号（R/V Shirase）于南大洋海域开展海面重力与地磁测量。海底压力通过在南大洋水深约4000米海底布设的压力计进行监测，该设备每年夏季完成布设与回收。
