Marine geophysical observations (geomagnetic 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.本数据集涵盖两类观测数据：其一为在南大洋海域搭载白濑号（R/V Shirase）科考船开展的海面重力与地磁测量数据；其二为部署于南大洋约4000米水深海底的压力计所监测的海底压力数据，该压力计于每年夏季完成安装与回收作业。
