Data from lake cores from lakes in northern Seward Peninsula, Alaska

In 2009 and 2010, we extracted sediment cores from seven key study lakes on the NW Seward Peninsula. Various physical, chemical and biological properties were measured including grain size, magnetic susceptibility, macrofossils, %TOC, del13C, del15N, % biogenic silica, grain size, and composition using smear slides.2009年与2010年，我们从苏厄德半岛西北部的7处关键研究湖泊中采集了沉积物岩芯。研究团队对其多项物理、化学及生物学特性进行了测定，涵盖粒度、磁化率、宏体化石、总有机碳占比（%TOC, Total Organic Carbon）、δ¹³C、δ¹⁵N、生物硅占比、粒度，以及采用涂片法分析的组成。
