Marine geophysical observations(geomagnetic 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.本数据集收录两类观测数据：一是在南大洋海域Shirase号科考船（R/V Shirase）上开展的海面重力与地磁测量数据；二是布设于南大洋约4000米深海底、每年夏季布设并回收的压力计所监测得到的海底压力数据。
