Observation 3.1. Cruise summary JAMSTEC provided a single-day boarding experiment on the R/V Natsushima to the children who won prizes in the 16th Postcard Design Contest and their parents, in order that they had a better understanding of and deeper interests in the oceans. Boarding experiments on the R/V Natsushima were carried out in the three days including the underwater navigations of the remotely operated vehicle Hyper-Dolphin. During the underwater navigations of Hyper-Dolphin, many deep-sea organisms such as conger and holothurian were observed through the high-definition marine camera. We carried out the submarine experiments during the underwater navigations. Around the sea floor, the children and parents tried to operate the Hyper-Dolphin from the control room on the R/V Natsushima as well. 3.2.
