Fig. 5: The PSA patterns, mean sortable size SS and sea level fluctuations since 35,000 BP.

From: Changes in marine sedimentation patterns in the northeastern South China Sea in the past 35,000 years

Fig. 5

(Top) The PSA patterns of the depositional periods P1, P3 and P4. Each pattern shows different sedimentary facies. (middle) The sortable silt mean size \((\overline{{SS}})\) of MD18-3545, which responds to the bottom current intensity during sedimentation. (bottom) The global sea level change in the past 35,000 yr5. Generally, a bottom current intensity is positively correlated to the gradient of the sea level change. The strong erosion in Period 2 occurred at a lowstand of the sea level or at water depths lower than about −60 m. The depositional Periods 3 and 4 occurred when the sea level is higher than −60 m.
