前回男女群島 でたくさんの写真とったはが、防水カメラにもかかわらず水没しちゃったので、今年は慎重活動した。今回はカヤックをつかったCTDキャストと素潜りでの調査をした。 Last time I went to the Danjo Islands, I took along a waterproof camera that decided to take on water. So this time, I was very careful in the way I went about taking photos. This year, I also took along the kayaks to make CTD casts as well as the usual skin-diving work. カヤックとCTDによって、94回も計測した。さらに、流速計やクロロフィル計を24時間設置した。生物調査は写真でおこない、藻類は小型のものがおおく、サンゴとイソギンチャクがめだっていた。魚もたくさんいた。 With the kayak and the CTD, 94 casts were completed. I also setup a velocity datalogger and chlorophyll-a logger, which took measurements for 24 hours. The flora/fauna survey was conducted mostly with photos. There were alot of small benthic macrophytes, but the corals and anemones stood out. Not to mention the plethora of fish. K邊研のD1のN塚 さんは「K村くん以上におろします!」と宣言し、CTDの観測を頑張ってくれた。N塚さん、申し訳ないがK村くんは 西表島 で、200回以上やったよ。 Dr. K's PHD student, Mr. N proclaimed that he would do more CTD casts than Mr. K (my student), and so he did a g...
