Abstract. Fossil ostracods have been widely used for Quaternary paleoenvironmental reconstructions especially in marginally marine environments (e.g. for water depth, temperature, salinity, oxygen levels, pollution). But our knowledge of the autoecology of indicator species, the base of paleoenvironmental reconstructions, remains limited and commonly lacks robust statistical support and comprehensive comparison with environmental data. We analysed marginally marine ostracod taxa at 52 sites in Hong Kong for which comprehensive environmental data are available. We applied linear regression models to reveal relationships between species distribution and environmental factors, and identified indicator species of environmental parameters. For example, Sinocytheridea impressa and Neomonoceratina delicata indicate botttom-water hypoxia &#8211; eutrophication, and heavy-metal pollution - increased turbidity, respectively. Many taxa are widespread throughout the northwestern Pacific &#8211; Indo-Pacific regions, including temperate (South China Sea to Japan and Russia), subtropical (i.e., Indo-Pacific to the East China Sea), and tropical (i.e., Indo-Pacific and South China Sea) taxa. With statistical support from ecological modeling and comprehensive environmental data, These results provide a robust baseline for ostracod-based Quaternary-Anthropocene paleoenvironmental reconstructions in the tropic&#8211;extratopic northwestern Pacific and Indo-Pacific.

Fluvial deposits from several cores, including CSDP-1 on the Yellow Sea Basin until the late Pleistocene, also suggest that the SYS included continental/fluvial environments up to this period 19,[44][45][46][47] . Moreover, the Zhe-Min uplift (ZMU), which extends from southern China to the western part of the Jeju Strait along the Jingshan-Shaoxing-Gwangju Fault, and was high terrain until the late were supplied by the freshwater discharged from exposed nearby shelves and the weak TWC.…”

Phytoclasts in the form of plant debris in terrestrial sediments can be transported by water to distant areas because they are lighter than inorganic particles. The semi-enclosed East Sea, which is connected by narrow straits to other seas, is adjacent to continental shelves that are the source area of terrestrial sediment flowing into the East Sea. These shelves alternated repeatedly between terrestrial and marine environments as a result of eustatic sea-level changes during the Late Quaternary. Palynofacies analyses of the IODP Exp. 346 U1430 core, located in the Eastern South Korea Plateau (ESKP) of the East Sea, have revealed changes in the size and concentration of phytoclasts associated with glacial–interglacial cycles. These changes are generally negatively correlated with the global sea-level curve, and their anti-phase cycles with high amplitude are clearly evident during the last ca. 750 ka with the geotectonic stabilization period. In particular, several coarse-grained phytoclasts were observed during the glacial period, including the Last Glacial Maximum (LGM). These findings suggest that the concentration and size of phytoclasts flowing into the East Sea were influenced by changes in the distance of the source area, depending on the water depth of the strait and nearby shelves owing to sea-level changes in tandem with glacial–interglacial cycles and geotectonic events.

“…There were three small-scale transgressions that occurred in the South Yellow Sea at ~1.66 Ma, ~1.44 Ma, and ~1.03 Ma in the Early Pleistocene (Liu et al, 2016a). The first transgression began at 1.66 Ma due to regional subsidence caused by the Zhe-Min Uplift (Liu et al, 2018). However, minor subsidence from the uplift of the Miaodao Islands, at ~0.83 Ma, caused the first transgression along the west coast of the Bohai Sea (Liu et al, 2016b).…”

“…The first transgression age, sea-level high stand, and the transgressions in the Early-Middle Pleistocene vary throughout eastern China. In previous studies, the transgression ages have been calculated by linear interpolation on the basis of the polarity reversal boundary age of the magnetic strata (Cheng Yu et al, 2016;Liu et al, 2016aLiu et al, , 2016bLiu et al, , 2018 or using the astronomical rhythms method (Yi et al, 2012(Yi et al, , 2015Yao et al, 2014). However, continuous sediment stratigraphy is a requirement to use the previously mentioned methods.…”

Sedimentary sequences in the Subei Basin are complex and have been affected by interactions between the ocean and rivers since the Late Pliocene, including the Yellow River, Huaihe River, and the Yangtze River. This sedimentary evolution, in particular the timing of Pleistocene transgressions, has long been a matter of controversy owing to the lack of precise chronological evidence. The aim of this study is to explore the evolution of the sedimentary environment throughout the past 3.00 Ma in this region on the basis of a comprehensive analysis of particle size and foraminifera and ostracods collected in the TZK9 core from the Subei Basin combined with geochronological studies of magnetostratigraphy, AMS14C and optically stimulated luminescence (OSL). The results show that fluvial facies in the sedimentary environment from 3.00 to 1.01 Ma. There were fluvial facies and reflects six sea‐level high stands from 1.01 to 0.25 Ma. The study area was affected by four large‐scale transgressions since 0.25 Ma. The four marine sedimentary layers known as DU7 (buried at 48–52 m), DU5 (buried at 35–41 m), DU3 (buried at 16–23 m), and DU1 (buried at 2–4 m) are recorded in the MIS7 (210–250 ka), MIS5, MIS3, and Holocene, respectively. The magnitude of the DU5 transgression was identical to that of the DU3 transgression, both were larger than the DU7 transgression, and the DU1 transgression was the weakest. The variation of transgression strength reflects the influence of global changes in sea level, tectonic subsidence, shell ridges, and sand dams. In the TZK9 core, we found evidence of seven sea‐level high stands from the Early–Middle Pleistocene, and the first one caused by regional rapid subsidence and could be traced back to 0.83‐0.84 Ma. The sea‐level high stands and the age of the first one recorded above was different from other cores in eastern China, this was caused by the lack of absolute age control and the differences in paleotopography during this period. This study reconstructs sedimentary evolution, determines the transgression and its age, establishes the chronology since the Late Pliocene, and provides a scientific framework for further paleoenvironmental and tectonic studies. The results of this study highlight the important role that local tectonics and global sea level play in the sedimentary evolution and transgressions that have occurred in the western Subei Basin.
