2015-2016 Field deployment data from Arctic Lakes in Northwest Territories, Canada: L520

Date from Lake 520. Time series data from sensors and water samplers deployed as OsmoSamplers at the bottom of seasonally ice-covered permafrost lakes in the Mackenzie River delta, Northwest Territories, Canada, from August 2015-August 2016. Sensor data includes water temperature, pressure, dissolved oxygen, light, and conductivity. Water samples were analyzed for dissolved major, minor and trace ions and methane concentrations. Study lakes include four lakes near Inuvik in the mid-delta (Lakes 56, 129, 280, and 520), two lakes in the outer delta near the outflow of the Middle Channel (informally named Swiss Cheese and Manta Lakes), and two lakes on North Richards Island (informally named North Head sites 1 and 2).

本数据集包含520号湖的相关数据。其为2015年8月至2016年8月期间，部署于加拿大西北地区马更些河三角洲季节性冰封多年冻土湖湖底的传感器与渗透采样器（OsmoSamplers）所采集的时序观测数据。传感器观测数据涵盖水温、压力、溶解氧、光照强度与电导率。研究团队对采集的水样开展了溶解态常量离子、微量离子、痕量离子以及甲烷浓度的分析测试。本次研究涉及的湖泊包括：三角洲中部因纽维克附近的4座湖泊（56号湖、129号湖、280号湖与520号湖）、外三角洲中水道入海口附近的2座湖泊（非正式命名为瑞士奶酪湖与蝠鲼湖），以及北理查兹岛上的2座湖泊（非正式命名为北角站点1与站点2）。
