Late Pleistocene forced-regressive deposits on the Sunda Shelf (Southeast Asia)

Stratigraphic development during the Late Pleistocene and Holocene offshore of the Yellow River delta, Bohai Sea

“…However, the reconstructed sea-level variations suffer from inherent uncertainty and show discrepancies of up to tens of meters during certain time intervals (e.g., Marine Isotope Stage 3). Siliciclastic-dominated continental shelves provide an alternative source of sea-level data, and late Quaternary coastal and shelf deposits have recently proved to contain good stratigraphic records of sea-level and paleoenvironmental changes (e.g., Banerjee, 2000;Hanebuth et al, 2000;Yokoyama et al, 2000;Lobo et al, 2001;Marsset and Bellec, 2002;Hanebuth et al, 2003;Schimanski and Stattegger, 2005;Hanebuth et al, 2006;Liu et al, 2007). Water depth in the Bohai Sea is mostly less than 30 m, and the average depth is only 18 m (Fig.…”

A high-resolution history of vegetation and climate history on Sunda Shelf since the last glaciation

“…Sunda Shelf, the second largest continental shelf in the world, 1.8×10 6 km 2 , emerged during the glacial times owing to low sea surface level. SONNE cruise 115 (December 1996-January 1997) got a lot of high resolution sedimental records [2][3][4][5][6][7] along a transect across the Sunda Shelf covering the last 50 000 years. But whether the exposed shelf was covered with vegetation or with what vegetation is still an unanswered question, which may be important to our understanding of the past climate changes in the tropics.…”

The records of coastline changes reflected by mangroves on the Sunda Shelf since the last 40 ka

“…Mangroves are now commonly found along the coast of the Malaysian Peninsula and adjacent islands, so the loss of mangrove indicates the receding of the coastline. The development of soil horizon, an important stratigraphic marker, formed on the top of the Regressive Unit [6] , is also the proof of early land emergence during low sealevel in high glacial times. And foraminifers are completely lacking is also associated with land emergence [7] .…”

“…A soil horizon covered the top of the regressive deposits, so it was probably related to the land emergence during sea-level fall [20,21] , which date from 20 to 23.5 14 C ka BP [6] , while at 380-382 cm, the deposits was soil, so the 22.81 14 C ka BP at the depth of 534-536 cm is too young and abundant it. Just like Core 18302, the top age of this core is derived from extrapolations.…”

“…Sonne cruise 115 (December 1996-January 1997) got a lot of high resolution sedimental records along a transect across the Sunda Shelf covering the last 50000 years [2][3][4][5][6][7] and Hanebuth et al [3] found the sea levels changed greatly since the last deglaciation, The reconstructions of the sea-level curves of global validity [8][9][10][11][12] also indicated there were several minor sea-level fluctuations during the past glacial cycle (Figure 1), but they do not resolve shorter variations and also show discrepancies of up to tens of meters during certain time intervals. So there are no detailed studies about the coastline Figure 1 (a) The location of the studied area and cores; (b) SO115 transect on the Sunda Shelf (black line is the transect, grey refers to the exposed Sunda Land; (c) the locations of studied cores(Modified from Hanebuth et al [7] ).…”
