Coastal barrier dune construction during sea-level highstands in MIS 3 and 5a on Tottori coast-line, Japan

Origin and Paleoenvironmental Significance of the Old Red Sand Along the Southeast Coast of China

“…Therefore, we can draw the conclusion that the ORS developed in the warm-humid high sea level stages during the last interglacial period and in the relatively cold-dry low sea level stages during the last glacial period, but not occur in the lowest sea level stages during the LGM, the formation of the ORS was restricted jointly by climate changes of the source area and the distance from the shoreline that resulted from sea level changes. This result is consistent with previous studies that red dunes developed in high sea level stages and in relatively low sea level stages (Giannini et al, 2007;Tamura et al, 2011;Jayangondaperumal et al, 2012;Alappat et al, 2013). During the last interglacial period, under a warm-humid climate, the precipitation increased significantly, rivers transported sufficient sand supply to the coast, the intensified East Asian summer monsoon transported these sand materials and deposited along the coast.…”

Coasts and climate

“…In the case of the Late Pleistocene dunes of the Tottori coastline, Japan, largescale shifts in shoreline position have contributed to significant differences in the depositional setting and morphosedimentary character of dunes. This points to the importance of gross coastal configuration, as determined by sea level, on coastal dune development (Tamura et al, 2011b).…”

Assessing the Environmental Impacts of a Beach Nourishment Operation, Morro Bay, Ca

“…Using a trowel, sediment samples were collected from the stratigraphic pits when individual strata were visually different from the surficial sediments. The results of the stratigraphic analyses were used to look for changes in stratigraphy (Hypothesis 1B) by providing data on how the stratigraphy of the dumpsite differed from the stratigraphy of the other sampling sites (Tamura et al, 2011). The data were also used to understand how dredge material was moving throughout the study area (Hypothesis 1C).…”
