Depth to sea floor and sea ice thickness data_Davis_Summer 2018-19

Depth to sea floor and sea ice thickness data measured at various locations around the Vestfold Hills, Davis station, East Antarctica, during the 2018-19 austral summer.

Depth to sea floor and sea ice thickness measures in meters obtained using a weighted tape measure deployed through a hole (5 cm) drilled in the sea ice. Sea ice thickness was determined by snagging the weight on the underside edge of the ice hole as the tape measure was retreived.

本数据集收录2018-2019年南半球夏季期间，于东南极洲戴维斯站（Davis Station）周边韦斯特福尔丘陵（Vestfold Hills）各测点采集的海床深度与海冰厚度数据。
本次采集的海床深度与海冰厚度均以米为单位，测量流程为在海冰上钻取直径5厘米的冰孔，下放系有重锤的卷尺开展测量。海冰厚度通过回收卷尺时，使重锤钩挂于冰孔下沿的方式确定。
