Perspectives on a Seamless Marine-lake Sediment Coring Study in East Antarctica
The Antarctic Ice Sheet (AIS) is one of the largest potential contributors to future sea-level changes. Recently, an acceleration of AIS volume loss through basal melting and iceberg calving has been reported based on several studies using satellite observations, including radar altimetry, interferometer, and gravity measurements. A recent model that couples ice sheet and climate dynamics and incorporates hydrofracturing mechanism of buttressing …
Pleistocene deep-sea ostracods from the Oki Ridge, Sea of Japan (Iodp Site U1426) and condition of the intermediate water
The Sea of Japan (also termed the East Sea) has a circulation system isolated from the Pacific Ocean and East China Sea. The East Asian winter monsoon drives the circulation system and cools the Tsushima Warm Current (TWC) to form the Japan Sea Intermediate–Proper Water (JSIPW). The intermediate water conveys oxygen to deep-sea floors, which is available for benthic animals. During the Pliocene (3.5–2.8 Ma), Temperate Intermediate Water (TIW) was…
Variation in subsurface water temperature and its link to the Kuroshio Current in the Okinawa Trough during the last 38.5 kyr
Correlation between faunal transitions of benthic foraminifera and ballasting of particulate organic carbon by siliceous plankton during the Holocene off San-in district, southwestern Japan
We investigated the biotic response of benthic foraminifera (Rhizaria) to Holocene paleoceanographic changes in a upper bathyal environment by examining fossil benthic foraminifera younger than ~13 ka from core GH87-2-308 (316-m water depth) off San-in district, southwestern Japan. A non-metric multidimensional scaling (nm-MDS) analysis enabled the distinction of three main benthic foraminiferal assemblages and two faunal transitions. The phase 1…
Variations in sedimentary environments in the forearc and backarc regions of the Ryukyu Arc since 25 ka based on CNS analysis of sediment cores
Different nature of glacial CaCO3 constituents between MIS 2 and MIS 12 in the East Sea/Japan Sea and its paleoceanographic implication
Late Quaternary glacial–interglacial variations in sediment supply in the southern Drake Passage
Geochemical characteristics of marine sediment from the southern Drake Passage were analyzed to reconstruct variations in sediment provenance and transport paths during the late Quaternary. The 5.95 m gravity core used in this study records paleoenvironmental changes during the last approximately 600 ka. Down-core variations in trace element, rare earth element, and Nd and Sr isotopic compositions reveal that sediment provenance varied according …
Land—sea linkage of Holocene paleoclimate on the Southern Bering Continental Shelf
Detailed diatom records within surface and core sediments from the Southern Bering Continental Shelf (SBCS) reveal that the Holocene evolution of sea-ice distribution is associated with low pressure patterns. Holocene sea-ice distribution over the SBCS was mainly controlled by the location of the Aleutian Low. The corresponding paleoceanographic and paleoclimate conditions can be divided into three stages: (1) the early Holocene (before 7000 cal.…
