Temperature and pressure collected at the intertidal zone from the area of Polish Polar Station Arctowski in King George Island from 2010-12-07 to 2011-03-18 (NCEI Accession 0163606)

This dataset contains time series of temperature and pressure from four pressure and temperature logging stations, collected at the seafloor near Polish Polar Station Arctowski, King George Island, Antarctica, from 2010-12-07 to 2011-03-18.

Given the increased glacier retreat,summer melts, sea level rise and ozone losses the intertidal zone is likely to be one of the most rapidly altering of environments but also one of the least investigated in polar waters. This study aims to quantify summer temperature variability in some habitats of the intertidal zone at King George Island. Three transects were selected across tidal flat. Four temperature loggers were deployed at each of them from extreme low water spring tide level to extreme high water spring tide level between 07.12.2010 and 18.03.2011. All the loggers were deployed at the rocky substratum. In all the three transects average temperature increased with tidal height. Much higher temperature variability was recorded at higher than at lower tide locations. Differences in temperature between the three study transects existed. Results obtained from the studied tidal flat show that several factors combined altogether, including: water movement by tidal forces, wave action, air temperature, sun light intensity, shore lithology and the presence of ice and snow in the area, seem to influence its temperature.

本数据集包含2010年12月7日至2011年3月18日期间，在南极洲乔治王岛波兰阿尔克托夫斯基（Arctowski）极地科考站附近海底布设的4套温压记录仪采集的温度与压力时间序列数据。

鉴于冰川消退、夏季融冰、海平面上升与臭氧损耗加剧，潮间带（intertidal zone）极有可能是极地海域中环境变化最迅速的区域之一，同时也是研究程度最低的区域之一。本研究旨在量化乔治王岛潮间带部分生境的夏季温度变化特征。研究人员在潮滩上布设了3条断面，于2010年12月7日至2011年3月18日期间，在每条断面从大潮低潮位至大潮高潮位的范围内各部署4台温度记录仪，所有记录仪均布设于岩石底质处。三条断面的平均温度均随潮位升高而上升，且高潮位区域的温度变异性显著高于低潮位区域，三条研究断面间亦存在温度差异。基于该潮滩的研究结果显示，潮流作用产生的水体运动、波浪作用、气温、光照强度、岸带岩性以及区域内冰雪覆盖情况等多种因素共同影响了其温度状况。
