Reconstruction of Paleoenvironment and Identification of Historical Tsunami Deposits by Geochemical Analyses in Iwanuma City, Miyagi Prefecture, Japan
Identifying invisible tsunami deposits in the geological record is challenging and requires multiproxy analyses. In particular, geochemical signatures provide useful information for identifying paleo-tsunami deposits, as well as for reconstructing the paleoenvironment history, even when other proxies are equivocal. In addition, geochemical proxies help to provide an understanding of environmental changes that occur post-tsunami. As a result, they…
Late Holocene centennial to millennial-scale variability in lower trophic level productivity off southern Hokkaido, Japan, and its response to dissolved iron-replete Coastal Oyashio dynamics
Little is known about the dynamics of marine food chains spanning primary to higher trophic levels on centennial and longer timescales, especially where the supply of dissolved iron limits primary productivity. To elucidate the long-term dynamics of biological productivity in the Coastal Oyashio (CO), which is a major pathway for transporting dissolved iron into the western North Pacific from winter to spring, we reconstructed the lower trophic l…
Relationship between δ 15 N values of bulk sediments and total organic carbon concentration in response to orbital-scale biogenic opal production in the Bering slope area over the last 600 kyrs
Reappraisal of sea-level lowstand during the Last Glacial Maximum observed in the Bonaparte Gulf sediments, northwestern Australia
Weak monsoon event at 4.2 ka recorded in sediment from Lake Rara, Himalayas
Reorganization of the Kuroshio and Subtropical Gyre in the Northwest Pacific during the Northern Hemisphere Glaciation
Sakurajima-Satsuma (Sz-S) and Noike-Yumugi (N-Ym) tephras
Using foraminiferal Mg/Ca ratios to detect an ocean-warming trend in the twentieth century from coastal shelf sediments in the Bungo Channel, southwest Japan
To assess abnormal warming of temperature in southwest Japan's coastal seas during the twentieth century, we developed a 200 yr interannually resolved record of planktonic and benthic foraminiferal Mg/Ca-based temperature using neritic coastal sediment cores. The winter to late spring bottom temperature (50 m) record, based on benthic foraminiferal ( Nonion japonicum) Mg/Ca ratios in the Bungo Channel (BC), showed consistent variation with observ…
