Marine geophysical observations (Ocean Bottomo Pressure Gauge data) (JARE62)

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.本数据集包含两类观测数据：一是在南大洋海域依托白濑号科研考察船（R/V Shirase）开展的海面重力与地磁测量（sea-surface gravity and geomagnetic measurements）数据；二是在南大洋水深约4000米的海底布设压力计（pressure gauge），并于每年夏季回收该设备以监测海底压力（sea bottom pressure）所获取的监测数据。
