Sediment properties and geochemical proxies of gravity cores obtained on the continental slope and rise at the eastern side of Hillary Canyon in the Ross Sea since Last Glacial Maximum@en

For the reconstruction of paleoenvironment, 14C ages, magnetic susceptibility, number of gravel, granulometry, biogenic opal, total organic carbon, d13C, total nitrogen, d15N, total organic carbon-total nitrogen ratio, CaCO3 were measured. Druing the PNRA-Rosslope II Expedition 2014, gravity cores(RS14-GC1, GC2, and GC3) on the continental slope and rise at the eastern side of Hillary Canyon in the Ross Sea since Last Glacial Maximum.为开展古环境重建研究，本数据集测定了碳十四年代 (14C ages)、磁化率 (magnetic susceptibility)、砾石数量 (number of gravel)、粒度分析 (granulometry)、生物蛋白石 (biogenic opal)、总有机碳 (total organic carbon)、碳同位素δ¹³C (d13C)、总氮 (total nitrogen)、氮同位素δ¹⁵N (d15N)、总有机碳-总氮比值 (total organic carbon-total nitrogen ratio) 以及碳酸钙 (CaCO3)。2014年PNRA-罗斯斜坡II号科考航次 (PNRA-Rosslope II Expedition 2014) 期间，科研团队于罗斯海希拉里峡谷东侧的大陆坡与陆隆区域采集了重力岩心 (gravity cores) RS14-GC1、GC2及GC3，其沉积序列覆盖末次盛冰期 (Last Glacial Maximum) 以来的地层。
