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 trace element analyses at intervals of 4–10 cm according to the age model. The samples were freeze-dried under vacuum, and the fine fraction (< 63 μm) 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>

Distribution. Cold-temperate waters of the N Pacific, from Bonin Is (27° N, 142° E) and Ryukyu Is N to Yellow Sea, Sea ofJapan, Sea of Okhotsk, Bering Sea and Gulf of Alaska; occasionally reaching tip of Baja California, Mexico, to the S of E Pacific in winter. Except on their N summer grounds, only a few sightings in the E Pacific Ocean during the past 50 years. in Balaenidae
