Sedimentological, Geochemical and Isotopic Evidence from the Bering and Chukchi Seas through the last Deglaciation and Holocene

This dataset contains data from 5 cores from the Bering and Chukchi Seas, and was used to aid interpretations of past productivity, terrestrial input and circulation , based on d13Corg, %TOC, bulk d15N, %Norg, Corg/Norg, elemental X-ray fluorescence (XRF) data, grain size analysis, bulk density and magnetic susceptibility data. Also included are color data. The cores used in this study were collected during two legs (HLY02-02 and HLY02-04)
of the Arctic West Summer 2002 cruise of the USCGC Healy in the Bering and Chukchi Seas led by Julie Brigham-Grette (University of Massachusetts, Amherst), Neil Driscoll (Scripps Oceanographic Institution), and Lloyd Keigwin (Woods Hole Oceanographic Institution, WHOI).

本数据集包含采自白令海与楚科奇海的5个沉积岩芯的分析数据，旨在依托以下指标辅助古生产力、陆源输入及环流特征的古环境解译：有机碳同位素δ¹³Corg、总有机碳占比（%TOC）、全样氮同位素δ¹⁵N、有机氮占比（%Norg）、有机碳氮比（Corg/Norg）、X射线荧光光谱（X-ray fluorescence, XRF）元素数据、粒度分析数据、沉积物体积密度及磁化率数据，同时包含颜色表征数据。本研究使用的岩芯采集自USCGC Healy号破冰船2002年北极夏季西部航次的两个航段（HLY02-02与HLY02-04），作业区域覆盖白令海与楚科奇海，该航次由马萨诸塞大学阿默斯特分校的Julie Brigham-Grette、斯克里普斯海洋研究所的Neil Driscoll以及伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）的Lloyd Keigwin牵头主持。
