“…The recent development of a tephra catalog for the Japan region, mainly based on terrestrial investigations (e.g., Machida and Arai 2003), allows accurate identification and correlation of offshore and onshore tephra beds over a broad area. The Late Pleistocene to the Holocene sediments in the Japan Sea are characterized by alternations of fine light and dark clayey layers, reflecting variability in the paleoenvironment (e.g., Oba et al 1991;Tada et al 1992 Kido et al 2007). The broad occurrence of these changes is indicated by the synchronous incidence of dark layers among the three sites of ODP Legs 127/128 (Tada et al 1992).…”

Tephra is a product of large and explosive volcanic events and can travel thousands of kilometers before deposition. Consequently, tephra deposits are common in terrestrial, lacustrine, marine, and glacial environments. Because tephra deposition is a geologically synchronous event, tephras constitute important isochrones in the Quaternary sequence, not only in Japan but also throughout the northwest Pacific and its marginal seas. As a result, establishing the chronostratigraphic order of tephra deposits is an effective tool for assessing local and regional stratigraphies and for correlating events among sites. For example, tephrostratigraphy can provide precise chronological constraints for other stratigraphic data, such as magneto-and biostratigraphic data. Spatiotemporal variability in the occurrence and geochemistry of tephras can also be used to trace the magmatic evolution of island arcs and their relationships to regional tectonics. In a paleoclimatic context, tephra deposits allow the correlation of past climate events among terrestrial, lacustrine, and marine environments. Tephrochronology is also a fundamental element used in reconstructing the marine reservoir effect, where the ages of tephra in marine and terrestrial settings are compared. Therefore, tephra is a valuable tool not only in stratigraphy, chronology, and volcanology but also in paleoceanography and paleoclimatology.

“…Igarashi, 1994;Pickering et al, 1999; Kameo et al, 2006;Kitamura et al, 2008). In addition, anoxic conditions within intermediate water have not been identified from sediments deposited in the Japan Sea during interglacial periods (Kido et al, 2007). Based on these observations, it appears that the temporal distribution of G. inflata in the Japan Sea is governed neither by the absence of G. inflata in the Kuroshio Current region off Japan nor low levels of dissolved oxygen in deep-sea regions of the Japan Sea.…”

“…Based on the ages of stratigraphic datums reported by Berger et al (1994), the ages of these horizons are estimated to be 1.46-1.3 Ma, corresponding to interglacial stages 47-41. G. inflata has not been recognised from other middle PleistoceneHolocene deep-sea sediments (Oba et al, 1991;Domitsu and Oda, 2006;Takata et al, 2006;Kido et al, 2007).…”

The Early Pleistocene fossil record of the Japan Sea reveals that the planktonic foraminifer Globorotalia inflata succeeded in expanding its range from the East China Sea to the Japan Sea during interglacial stages of the Early Pleistocene; however, the species is only found in surface sediment samples from the southwestern-most part of the sea. Based on the ecology of G. inflata and the water mass structure of the Japan Sea, it appears that its geographical distribution is mainly controlled by the low temperature of the intermediate water, which is caused by the cool-water mass of Japan Sea Proper Water. The temporal and spatial patterns of G. inflata occurrence indicate that the intermediate water at 200 m depth during interglacial stages between 1.46 and 1.3 Ma was warmest during the Quaternary. This warm intermediate water probably resulted from the influence of the low-salinity nature of the Tsushima Current due to the large inflow of East China Sea Coastal Water. After 1.3 Ma, the intermediate water at 200 m depth became cooler in a step-wise manner. This cooling can be explained by an intensification of thermohaline circulation in the Japan Sea associated with strengthening of the East Asian winter monsoon and an increase in salinity due to enlargement of the southern strait.

“…Recently Lee et al (2008) investigated alkenone temperature record of the East Sea over the past 190 kyr, and suggest that alkenone temperatures were very low (7−10°C) during the penultimate glacial period when the surface salinity was low. The low surface salinity during the penultimate glacial period was suggested by Kido et al (2007) based on foraminiferal oxygen isotopic records. If the salinity is a major factor of the warm signal, the alkenone temperature change during the penultimate glacial period should be like the same pattern as the last glacial.…”

Glacial sea surface temperature of the East Sea (Japan Sea) inferred from planktonic foraminiferal assemblage

In order to reconstruct the last glacial sea surface temperature (SST) of the East Sea, we investigated planktonic foraminiferal assemblage in the marine sediments of a piston core recovered from the Ulleung Basin, East Sea. For core top, the most dominant species is right coiling Neogloboquadrina incompta, while left coiling Neogloboquadrina pachyderma and Globigerina bulloides clearly dominate the glacial assemblages. Based on fauna count, we reconstructed past SST using modern analog technique (MAT) with a global dataset. However, the application of the global dataset may hinder the reconstruction of regional SST. In order to validate this, we tested for the foraminiferal assemblages of 51 surface sediments in the East Sea with MAT and the global dataset. The results show that the estimated MAT temperatures were completely different from the real SST of core top sites, indicating that MAT with the global dataset may not be applicable for the East Sea SST reconstruction. Therefore, we developed new statistical calculation method using East Sea fauna dataset only. According to this method, the glacial SST was 2°C lower than today for August, and 6°C lower for February. This glacial−interglacial change of August temperature is relatively smaller than other results, while February temperature is comparable.
