As well known, the Arctic Ocean are covered with vast and thick sea ice, it is difficult to grasp the state below sea ice from above sea ice. Analyzing the behavior of sea ice is directly related to the understanding of the Arctic region, and leads to a global understanding of the Earth. For the observation of sea ice above the sea surface, some methods using an airplane or a satellite has been established, however this method cannot observe sea ice below the sea surface. In order to observe sea ice in the Arctic Ocean, observation of sea ice from underwater is essential. For this reason, JAMSTEC is now developing an autonomous underwater drone called as COMAI that can navigate under the Arctic sea ice and continuously observe the shape and seawater condition of the sea ice. In this paper, the outline of COMAI is explained, and its kinetic performance is shown from the tank test results.
