Conductivity, temperature, and depth data from CTDs deployed on mooring N5 for the ASGARD Project, Bering Sea, 2017-2019

These data are part of the Arctic Shelf Growth, Advection, Respiration and Deposition (ASGARD) Rate Measurements project, funded as part of the North Pacific Research Board’s (NPRB’s) Arctic Integrated Ecosystem Research Program (IERP; http://www.nprb.org/arctic- program/). The program and research on this expedition was sponsored by NPRB, the Collaborative Alaskan Arctic Studies Program (CAASP, formerly the North Slope Borough/Shell Baseline Studies Program), the Bureau of Ocean Energy Management (BOEM), the National Science Foundation, and the Office of Naval Research Marine Mammals and Biology Program. In-kind support for this research cruise was contributed by the National Oceanic and Atmospheric Administration and the University of Alaska Fairbanks. For this study, 6 moorings were deployed in the northern Bering Sea and southern Chukchi Sea. Each mooring was equipped with a variety of instruments to provide time series of environmental conditions throughout the water column. Moorings were deployed during the R/V Sikuliaq cruise SKQ201709S in June 2017. With one exception, they were recovered during the R/V Sikuliaq cruise SKQ201813S in June 2018. One mooring, N5, was unable to be recovered because of problems with the mooring release, and was recovered by a small-boat operation staged out of Kivalina, AK, in July 2018. In the second year of the project, 6 mooring were re-deployed at the same locations during R/V Sikuliaq cruise SKQ201813S. Moorings were recovered during the R/V Ocean Starr (https://www.stabbertmaritime.com/vessels-2/ocean-starr/) ArcticIES Phase II Cruise, Leg 1 (no cruise id?). Two moorings were recovered by dragging (N1 and N5).

本数据集隶属于北极陆架生长、平流、呼吸与沉积（Arctic Shelf Growth, Advection, Respiration and Deposition, 简称ASGARD）速率测量项目，该项目由北太平洋研究委员会（North Pacific Research Board, 简称NPRB）旗下的北极综合生态系统研究计划（Arctic Integrated Ecosystem Research Program, 简称IERP；http://www.nprb.org/arctic-program/）资助。本航次相关研究及本项目由以下机构联合资助：NPRB、阿拉斯加北极联合研究计划（Collaborative Alaskan Arctic Studies Program, 简称CAASP，前身为北坡自治市/壳牌基线研究计划）、海洋能源管理局（Bureau of Ocean Energy Management, 简称BOEM）、美国国家科学基金会（National Science Foundation），以及海军研究办公室海洋哺乳动物与生物学项目（Office of Naval Research Marine Mammals and Biology Program）。本研究航次的实物支持由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration）与阿拉斯加大学费尔班克斯分校（University of Alaska Fairbanks）提供。本次研究共在白令海北部与楚科奇海南部布设6套锚系观测系统，每套锚系均搭载多类仪器，用于获取整个水柱的环境时间序列数据。锚系布设工作于2017年6月随“锡利夸克号”研究船（R/V Sikuliaq）航次SKQ201709S完成。除1套锚系外，其余锚系均于2018年6月随“锡利夸克号”航次SKQ201813S完成回收。其中锚系N5因锚系释放装置故障未能按计划回收，最终于2018年7月由从阿拉斯加州基瓦利纳港出发的小型作业船队完成回收。项目实施第二年，科研人员于2018年6月随“锡利夸克号”航次SKQ201813S在原有站位重新布设了6套锚系观测系统。后续锚系回收工作随“海洋星号”研究船（R/V Ocean Starr，https://www.stabbertmaritime.com/vessels-2/ocean-starr/）北极IES第二阶段航次第一航段完成（无对应航次编号）。本次回收作业中，共有2套锚系（N1与N5）通过拖曳方式完成回收。
