    Abstract

    Planktonic Foraminifera are unique paleo-environmental indicators through their excellent fossil record in ocean sediments. Their distribution and diversity are affected by different environmental factors including anthropogenically forced ocean and climate change. Until now, historical changes in their distribution have not been fully assessed at the global scale. Here we present the FORCIS (Foraminifera Response to Climatic Stress) database on foraminiferal species diversity and distribution in the global ocean from 1910 until 2018 including published and unpublished data. The FORCIS database includes data collected using plankton tows, continuous plankton recorder, sediment traps and plankton pump, and contains ~22,000, ~157,000, ~9,000, ~400 subsamples, respectively (one single plankton aliquot collected within a depth range, time interval, size fraction range, at a single location) from each category. Our database provides a perspective of the distribution patterns of planktonic Foraminifera in the global ocean on large spatial (regional to basin scale, and at the vertical scale), and temporal (seasonal to interdecadal) scales over the past century.

  • Lower Pleistocene Chinen Formation and its significance discovered in Kikai-jima, Kagoshima Prefecture, Japan

    Hiroki Matsuda, Masahide Hayashida, Shun Chiyonobu, Makoto Yamasaki, Keiichi Sasaki

    <p>The Upper Miocene to Lower Pleistocene Shimajiri Group, composed of muddy sediments, and the Lower to Upper Pleistocene Ryukyu Group, consisting of reef-complex deposits, are widely distributed throughout the Ryukyu Islands. The Lower Pleistocene Chinen Formation, which has an intermediate lithofacies, is sporadically distributed between both groups in the central and southern parts of Okinawa-jima. The Chinen Formation was previously believed to be limited to Okinawa-jima, but correlated outcrops, aged between 1.71 and 1.39 Ma, have recently been discovered in Kikai-jima, Kagoshima Prefecture. The outcrops consist of calcareous mudstone and sandstone, or sandy limestone rich in bryozoan fragments, with clear contacts between the underlying and overlying groups. The Chinen Formation overlies the So-machi Formation of the Shimajiri Group across a clearly defined angular unconformity, indicating post-depositional tilting and erosion of the Shimajiri Group. In contrast, there are no structural differences to indicate tilting during the period between the deposition of the Chinen Formation and that of the overlying Ryukyu Group. Therefore, Kikai-jima emerged as a result of relative sea-level fall after the deposition of the Chinen Formation, following which the supply of terrigenous sediment decreased.</p>

    As part of the Marine Geological Map Project of the Geological Survey of Japan, the geological survey cruise GB23 was undertaken in the northeastern East China Sea and western Sea of Japan. Although the water depth over most of the survey area is <200 m, deeper areas also exist, such as the Goto Canyon (water depth: 400–600 m) and the area southwest of the Goto islands and the Danjo Basin (maximum water depth: ~800 m). Seafloor sediment was sampled at 198 sites using a Kinoshita grab sediment sampler, a vibro-corer, a rock dredger, and a rock corer. Here we report the characteristics of seafloor sediments collected using the Kinoshita grab sediment sampler. Coarse sediment with a low mud content occurs in the Tsushima Straight. Finer sediment with a high mud content occurs in other parts of the survey area. The seafloor sediments contain bioclasts such as mollusc shells and coral remains, including fossilized shells. This report also presents preliminary results on the calcareous nannoplankton and main planktic foraminifera in the seafloor sediment samples.
