资源简介:
Manual measurements of sea ice thickness, sub-ice platelet layer thickness, freeboard, and snow thickness are distributed evenly and repeated along a 25km-long transect across Atka Bay every 2 to 4 weeks. At each measurement location, 5 holes were drilled through the ice in order to determine the aforementioned parameters, one in the center and one in a distance of five meters in each direction, to cover their small-scale spatial variabilities. The measurements have been mainly conducted by the meteorologist (Anna-Marie Jörss) and Klaus Guba, Ina Wehner, Julia Loftfield, Noah Trumpik, Roman Ackle, Wanderson Divino de Almeida Santos of the overwintering team.
针对海冰厚度(sea ice thickness)、冰下血小板层厚度(sub-ice platelet layer thickness)、冰面干舷(freeboard)及雪深(snow thickness)的人工测量工作,每2至4周沿阿特卡湾(Atka Bay)的一条25千米长的样带(transect)均匀布设测点并重复开展。在每个测量测点处,均会在冰面钻取5个钻孔以测定上述参数:1个位于测点中心,其余4个分别沿四个方向间隔5米布设,以此覆盖参数的小尺度空间变异性。本次测量工作主要由气象学家安娜-玛丽·约尔斯(Anna-Marie Jörss)以及越冬科考团队的克劳斯·古巴(Klaus Guba)、伊娜·韦纳(Ina Wehner)、朱莉娅·洛夫特菲尔德(Julia Loftfield)、诺亚·特朗普克(Noah Trumpik)、罗曼·阿克尔(Roman Ackle)、万德森·迪维诺·德·阿尔梅达·桑托斯(Wanderson Divino de Almeida Santos)共同完成。

背景概述
该数据集提供了2020年南极Atka Bay陆缘海冰和海雪的厚度及属性手动测量数据,包括海冰厚度、冰下血小板层厚度、自由板厚度和雪厚度等参数。测量沿25公里横断面每2至4周重复进行,覆盖从2020年6月到2021年1月的时间范围,旨在捕捉小尺度空间变异性,支持南极快速冰网(AFIN)和德国研究基金会(DFG)相关项目的研究。
