Mechanism underlying the millennial scale variation of offshore sediment transport in the North Yellow Sea

<p>Sediment cores YC10 (length: 548 cm, water depth: 54 m) and YC26 (length: 435 cm, water depth: 15 m) were collected by hammer drilling on a fishing vessel from the NYS in July 2016. The sediment cores were split lengthwise, described, photographed, and subsampled in the lab. They were sliced into thin sections for&nbsp;trace element analyses at intervals of 4&ndash;10 cm according to the age model. The samples were freeze-dried under vacuum, and the fine fraction (&lt; 63 &mu;m) was sieved from the bulk samples for further geochemical analysis. The number of samples for REEs in cores YC10 and YC26 was 71 and 80, respectively, while those for Sr-Nd isotopes were 12 and 14, respectively.</p>
