        Materials. We studied the bivalve mollusks collected from a submarine cave in the Ryukyu Islands, Japan (Kitamura et al. ).Some sublittoral limestone caves in the Ryukyu Islands are known to be inhibited by numerous species of tiny shells that are generally less than 5 mm in length (Hayami and Kase ).The fossils of these minute shells are preserved abundantly in the cave .   Specimens were collected from Daidokutsu, a submarine cave off Iejima Island in the Okinawa Islands, part of the Ryukyu Archipelago, Japan, by Koshin Yasumura and Shinta Fujimoto in and For extraction of meiofauna, the cave sediment samples were stirred with tap water and the supernatants were concentrated using a 30 μm opening mesh.

Cyclochlamys incubata (Hayami & Kase, 62, figs ); Holotype: UMUT RM. Three new species of echinoderid kinorhynchs are described from Daidokutsu, a submarine cave in Ryukyu Islands, Japan. Echinoderes gama sp. nov. is characterized by the presence of middorsal acicular spines on segments 4–8; lateroventral acicular spines on segments 7–9; lateroventral tubes on segment 5; sublateral tubes on segment 8; laterodorsal tubes on segment 10.

Daidokutsu Cave is located on the northeastern coast of Ie Island, Okinawa, Ryukyu Island Arc (Fig. 1A, B). The cave's entrance lies in about 19 m water depth on the fore-reef slope, and is roughly 18 m wide and 2 m high. The interior of the cave is very dark, 40 m long, and deepens abruptly inward to a maximum depth of 29 m (Fig.

1C). The aragonitic micro-bivalve Carditella iejimensis, which is less than mm in height and length, inhabits the sediment surface in a submarine cave off the Okinawa Islands, evaluate the use of this species as a quantitative paleoceanographic proxy, we analyzed the δ 18 O values of 50 living C.

Climatic and hydrologic variability in the East China Sea during the last years based on oxygen isotope records of the submarine cavernicolous micro-bivalve Carditella iejimensis Article Jun   The submarine cave Daidokutsu (“large cave” in Japanese) is located on the northeastern coast of Ie Island, off the Motobu Peninsula of Okinawa Island ().The cave's entrance lies in about 20 m deep on the fore-reef slope ().The cave deepens abruptly inward to a maximum depth of 31 m (Hayami and Kase, ).There is no evidence of the inflow of underground water into the cave.

The University Museum, The University of Tokyo, Bulletin. 1– The micro-bivalve Carditella iejimensis is less than mm in shell height and lives in the surface sediment within a submarine cave at Ie Island, Okinawa Islands, Japan.

A previous study interpreted that δ 18 O-derived temperature obtained from C. iejimensis shells indicates the water temperature between May and July of each year. This interpretation is based mainly on a statistically. Submarine cave Bivalvia from the Ryukyu Islands; systematics and evolutionary significance, Two new species of large mussels (Bivalvia Mytilidae) from active submarine volcanoes and a cold seep off the eastern North Island of New Zealand, with descriptions of a new genus.

We analyzed sediments and cavernicolous bivalve assemblages within cored sediments recovered from the Daidokutsu submarine limestone cave, which occurs in Pleistocene limestone on the fore-reef slope of Ie Island, off Okinawa, Japan. We found sand-sized brown grains within sediments aged 7,–6, cal BP, and identified the grains as debris derived from a red soil layer developed in.

Battle of Okinawa, (April 1–J ), World War II battle fought between U.S. and Japanese forces on Okinawa, the largest of the Ryukyu a is located just miles ( km) south of Kyushu, and its capture was regarded as a vital precursor to a ground invasion of the Japanese home islands.

Dubbed “the Typhoon of Steel” for its ferocity, the battle was one of the. Hokkaido, Honshu, Shikoku and Kyushu islands form a line from north to south. There are some other groups of islands including the Chishima (Kurile) Islands off the northeast of Hokkaido, the Izu-Ogasawara (Bonin) Island chain stretching south of Honshu, and the Ryukyu Islands stretching south of Kyushu.
