Davis Strait hydrographic mooring Level 2 data: temperature, salinity, and velocity measurements from the Davis Strait Observing System moorings, 2004 to 2022

The Davis Strait observing system was established in 2004 to advance understanding of the role of Arctic – sub-Arctic interactions in the climate system by collecting sustained measurements of physical, chemical and biological variability at one of the primary gateways that connect the Arctic and subpolar oceans. Efforts began as a collaboration between researchers at the University of Washington’s Applied Physics Laboratory and the Canadian Department of Fisheries and Ocean’s Bedford Institute of Oceanography, but has grown to include researchers from the Greenland Institute of Natural Resources, Greenland Climate Institute, Danish Technological University, University of Alberta and University of Colorado, Boulder. The project is a component of the NSF Arctic Observing and Atlantic Meridional Overturning Networks, and the international Arctic-Subarctic Ocean Flux (ASOF) program, Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP), Global Ocean Acidification Observing Network (GOA-ON), Arctic Monitoring Assessment Programme (AMAP) and OceanSITES system. A mooring array spanning the entire Davis Strait has been in place nearly continuously since September 2004 as part of the Davis Strait observing system, collecting year-round measurements of temperature, salinity and velocity extending to the sea surface/ice-ocean interface. The mooring typically included 14 moorings, 4 on each shelf and 6 in the center of the strait, that are recovered and data offloaded each autumn. Exact mooring location, instrumentation, and deployment duration varied slightly over time. This dataset consists of Level 2 data from the Davis Strait mooring array. Each file contains data from a single sensor (e.g., MicroCAT temperature and salinity measurements or ADCP velocity measurements) at one mooring site collected during a single deployment (typically one year long). Files also include quality control flags. More details about the project can be found at https://iop.apl.washington.edu/project.php?id=davis.

戴维斯海峡观测系统（Davis Strait observing system）于2004年启动建设，旨在通过在连接北极与亚极地海洋的核心门户之一开展物理、化学及生物变率的持续观测，深化对北极-亚北极相互作用在气候系统中作用的认知。该项目最初由华盛顿大学应用物理实验室研究人员与加拿大渔业与海洋部贝德福德海洋学研究所合作发起，后续合作范围持续拓展，纳入了格陵兰自然资源研究所、格陵兰气候研究所、丹麦技术大学、阿尔伯塔大学以及科罗拉多大学博尔德分校的科研团队。本项目是美国国家科学基金会（NSF）北极观测与大西洋经向翻转环流网络、国际北极-亚极地海洋通量（ASOF）计划、全球海洋船舶水文调查计划（GO-SHIP）、全球海洋酸化观测网络（GOA-ON）、北极监测与评估计划（AMAP）以及OceanSITES系统的组成部分。作为戴维斯海峡观测系统的组成部分，横跨整个戴维斯海峡的锚系观测阵列自2004年9月起几乎持续运行，全年不间断采集延伸至海表/海冰-海洋界面的温度、盐度与流速数据。该锚系阵列通常包含14套锚系设备，其中4套布设于陆架区域，6套布放在海峡中部，每年秋季均会回收锚系并卸载观测数据。锚系的具体布设位置、仪器配置与部署时长会随时间小幅调整。本数据集包含戴维斯海峡锚系观测阵列的二级（Level 2）数据。每个文件对应单次部署（通常为期一年）中单个观测站点的单台传感器数据，例如MicroCAT温盐测量数据或ADCP流速测量数据，同时附带质量控制标记。有关本项目的更多详细信息可访问https://iop.apl.washington.edu/project.php?id=davis。
