Grain Size Data for Sediment Core WGZ-GC-1 (Ross Ice Shelf, Antarctica)

Abstract: Grain size fraction and thermal conductivity every 1 cm along sediment core WGZ-GC-1. Grain sizes below 1 mm diameter were measured with a laser-diffraction particle size analyzer, and grain sizes above 1 mm diameter were wet-sieved and weighed. Thermal conductivity measured using the needle probe method. At the time of core collection, January 2015, the site was located 3 km downstream of the Whillans ice stream Grounding Zone below a 10m seawater cavity of the Ross Ice Shelf.

摘要：本数据集包含沉积物岩芯WGZ-GC-1每1厘米间隔的粒度组分与热导率数据。粒径小于1毫米的样品采用激光衍射粒度分析仪测定，粒径大于1毫米的样品则通过湿筛法筛分后称重。热导率采用针探法进行测定。岩芯采集于2015年1月，采样点位位于罗斯冰架（Ross Ice Shelf）下方10米海水空腔处，距离惠兰斯冰流（Whillans Ice Stream）接地带下游3公里。
