Cruise summary In order that children and their parents shall have a better understanding of and deeper interests in the oceans, JAMSTEC provided a single-day boarding experiment on R/V NATSUSHIMA to children who won prizes in the 15th Hagaki contest and their parents. Boarding experiment carried out in order all the three days including the operation of R/V NATSUSHIMA and ROV HYPER-DOLPHIN. While HYPER-DOLPHIN s dives, several kind of deep-sea organisms such as Chionoecetes japonicus and Megalodicopia hians were observed through the high-definition RV camera. At the deep seafloor, HYPER-DOLPHIN did some experiments which were proposed by children. For example, HYPER-DOLPHIN fished with special rod and mackerel for the question is it possible to fish at the bottom of ocean?. HYPER-DOLPHIN also carried polystyrene foams, ping-pong balls, cans of Coke, watermelon and other materials to the deep ocean for the question how does water pressure affect the materials?. After the experiment, participants had opportunities to control HYPER-DOLPHIN from the control

6 room on the ship as well. On the return way to port, they also had opportunities to operate NATSUSHIMA (see APPENDIX).

7 4. HYPER-DOLPHIN dive surveys 4.1 Observation equipments -suction sampler, multiple canister, binocular, microscope, cooler for aquaria, container, bait trap 4.2 Dive information #1556 July 29, 2013 Maximum depth: 835m -Observed organisms Amphipoda, Holothuroidea, Ophiuroidea, Crossaster papposus, Eualus biunguis, etc. -Experiments carried materials to see how water pressure affect them; pressure sheets, small lights, raw and boiled eggs, a ping-pong ball, a bottle of water, a bottle of Coke, a balloon, polystyrene foams, a ruler, a small water melon, candies, radishes. put lumps of chicken, mackerels, and bananas on the sea floor. set a bait trap and a memorial plate on the sea floor. try to collect iron sand using U-shaped magnet. collected ocean mud with MBARI. collect deep sea water using Niskin water sampling bottle.

8 #1557 July 30, 2013 Maximum depth: 828m -Observed organisms Anthozoa, Megalodicopia hians, Eualus biunguis, Amphipoda etc. -Experiment carried materials to see how water pressure affect them; pressure sheets, small lights, raw and boiled eggs, a ping-pong ball, a bottle of water, a bottle of Coke, a balloon, polystyrene foams, a ruler, a small water melon, candies, radishes, sunflower seeds. set a memorial plate on the sea floor. try to collect iron sand using U-shaped magnet. try fishing using special rod put lumps of chicken, mackerels, and bananas on the sea floor. get organisms using suction sampler. collected ocean mud with MBARI. collect deep sea water using Niskin water sampling bottle.

9 #1558 July 31, 2013 Maximum: 833m -Observed organisms Zoarcidae, Amphipoda, Ctenodiscus crispatus, Liparis tessellatus, Eualus biunguis, etc. -Experiment carried materials to see how water pressure affect them; pressure sheets, small lights, raw and boiled eggs, a ping-pong ball, a bottle of water, a bottle of Coke, a balloon,, polystyrene foams, a ruler, a small water melon, candies, radishes. set a memorial plate on the sea floor. try to collect iron sand using U-shaped magnet. try fishing using special rod put lumps of chicken, mackerels, and bananas on the sea floor. get organisms using suction sampler. collected ocean mud with MBARI. collect deep sea water using Niskin water sampling bottle

10 -Picture of several collected samples Collected sample; Megalodicopia hians Collected sample; Zoarcidae (left) and Liparis tessellatus (Right) -Conclusion It was heavy rain in the early morning of first day, but Ocean condition was basically okay. Nobody got seasick through all cruise. The children and parents were warmly welcomed to NATSUSHIMA and seemed having fun. We believe that our goal Having children better understanding of and deeper interests in the oceans is successfully achieved.
