Preliminary results of the deep-sea faunal survey conducted from the TR/V Seisui-maru of Mie University in April 2018 are presented. 18 taxonomists and ecologists working on a wide variety of animal taxa participated in this survey. Surveyed areas included the Kumano Sea (off Mie Prefecture) and south of the Kii Strait (off Tanabe Bay, Wakayama Prefecture), at depths of 80-821 m. Sampling gears employed were beam trawl and biological dredge. The collection is represented by macrobenthos and meiobenthos from 11 animal phyla, including arthropods, echinoderms, annelids and molluscans. The number of phyla occurring in each station varied from 3 to 7. The station with most diverse fauna at the phylum level was St. 3B (south of the Kii Strait, 421-543 m depth, sandy mud bottom). Meiofauna includes priapulids and small arthropods, such as ostracods, tanaidaceans, isopods, cumaceans and acarus. In addition to free-living species, parasitic crustaceans, platyhelminthes, acanthocephalans, annelids and cnidarians were also collected from fishes, ascidians, urchins, holothurians, crustaceans and polychaetes. Preliminary identifications are given for Ostracoda, Cirripedia, Amphipoda, Decapoda, Asteroidea,Ophiuroidea, Holothuroidea, polychaetes, Echiura, Mollusca and Xenoturbellida.

Preliminary results of the deep-sea faunal survey conducted from the TR/V Seisui-maru of Mie University in April 2019 are presented. A total of 20 taxonomists and ecologists working on a wide variety of animal taxa participated in this survey. Surveyed areas included the Kumano Sea(off Mie Prefecture)and south of the Kii Strait(off Tanabe Bay, Wakayama Prefecture), at depths of 112-775 m. Sampling gears employed were beam trawl and biological dredge. The collection is represented by macrobenthos and meiobenthos from nine animal phyla, including echinoderms, arthropods, molluscans and annelids. The number of phyla occurring in each station varied from seven to eight. The station with most diverse fauna at the phylum level was St. 3B(south of the Kii Strait, 775-661 m depth, mud bottom).Meiofauna includes priapulids, nematodes and small arthropods such as copepods, tanaidaceans, amphipods, isopods and cumaceans. In addition to freeliving species, cnidarians symbiotic on a gastropod and an antipatharian, and crustaceans parasitic on a fi sh and sea urchins were also collected. Preliminary identifi cations are given for Asteroidea, Ophiuroidea, Holothuroidea, Crinoidea, Cyclopoida, Siphonostomatoida, Tanaidacea, Isopoda, Decapoda, Mollusca, polychaetes, Bryozoa, Cnidaria and Nemertea.

In this study, we had investigated the benthic deep-sea fauna using the dredge and beam trawl in the region from the continental shelf to the continental slope of the Sea of Kumano, Mie Prefecture, during the No.1722 research voyage of the training ship Seisui-Maru of Mie University. The survey was carried out at 16 stations covering a depth range of 113-1059 m. The results of the survey, 14 phyla had been confirmed. Arthropod, echinoderm, annelid and molluscan macrobenthos were collected from all of the stations. The phylum number of each station was in the range from 4 to 11. The largest number of phyla had been confi rmed at St.10D of boulders bottom(768-800 m depth). Meiobenthos confi rmed in our sample were kinorhynchs, nematodes, tardigrades, loriciferans and small arthropods such as tanaidaceans, copepods and cumaceans. In addition to free-living species, parasitic copepods, isopods, platyhelminthes, acanthocephalans and nematodes had been found in fish, crustaceans and polychaetes.

By using the training ship Seisui-maru, we observed of detailed oceanic condition in the vicinity of Cape Shionomisaki, the tip of the Kii Peninsula in April, 2009 and in October, 2009. The sea level difference between Kushimoto and Uragami tide stations is used to monitor the flowing path of the Kuroshio, or to identify whether the Kuroshio is taking the straight path or the meandering path. It is shown that this sea level difference occurs in the narrow portion of about 7 km from off Cape Shionomisaki to off Oshima Island, and that the sea level difference is mainly created by the oceanic condition in the thin surface layer above 150 m. This indicates that the structure of the Kuroshio does not influence directly to the sea level difference between Kushimoto and Uragami. The sea level difference indicates whether warm and light Kuroshio Water is brought into shelf region to the west of Cape Shionomisaki or not, and whether the sea level difference between coastal waters to the west and to the east of Cape Shionomisaki. The success of this elaborated observation owe to improved facilities of the new training ship Seisui-maru2009 年 4 月と 10 月の 2 回にわたって, 勢水丸を潮岬周辺に派遣して, 従来に見られない詳細な海況の観測を実施した。黒潮の流路が直進路をとっているか, 蛇行路をとっているかをモニターするのに串本・浦神の検潮所間の水位差が用いられるが, この水位差は潮岬から大島の沖, 東西 7 km の部分で生じていることが示された。また, この水位差の殆どは, 僅か 100 ~ 150 m のごく表層の海洋構造によって作り出されたものであることが示された。串本・浦神の水位差には, 黒潮本来の構造が直接関与しているのではなく, 振り分け潮にともなう黒潮系水の潮岬西の沿岸域への侵入の有無, あるいはそれに伴って生じる潮岬東西の沿岸水の性質の違いを通してもたらされている。この微細海況観測成功には, 著しく向上した新しい二代目の勢水丸の能力が不可欠なものであった。
