TSG data collected by the CCGS Amundsen in the Canadian Arctic

The Canadian research icebreaker CCGS Amundsen is equipped with an underway ThermoSalinoGraph (TSG) system, which continuously records surface seawater temperature, salinity, fluorescence and sound velocity along the transit route. Quality Assurance/Quality Control (QAQC) data are available for the summer periods between 2005 and 2020, except in 2007, 2008 and 2012 where the system was faulty or the ship was in maintenance. The TSG data were corrected and controlled by comparing them to CTD-Rosette data and in situ measures when available. Outliers and suspicious measurements were removed from the dataset. Variables are provided every 7 minutes. Research programs participating in the Amundsen expeditions between 2005 and 2020 include, ArcticNet, CFL, Geotraces, Malina, IOL and BP, BREA, Weston, Netcare, JAMSTEC, Statoil and iBO, GreenEdge, BAYSYS, Sentinel Nord (BriGHT, BOND), DFO ROV vulnerable marine ecosystem, and the Kitikmeot marine Ecosystem.

加拿大科研破冰船CCGS阿蒙森号配备有连续测量的海洋热盐度计（TSG）系统，该系统沿航线持续记录海水表面温度、盐度、荧光和声速。2005年至2020年夏季期间（2007年、2008年和2012年除外，当时系统出现故障或船只处于维护状态）的质量保证/质量控制（QAQC）数据可用。TSG数据通过与CTD-Rosette数据以及现场测量数据进行比对进行了校正和控制。数据集中移除了异常值和可疑测量值。数据变量每7分钟提供一次。2005年至2020年期间参与阿蒙森探险的研究项目包括：ArcticNet、CFL、Geotraces、Malina、IOL和BP、BREA、Weston、Netcare、JAMSTEC、Statoil和iBO、GreenEdge、BAYSYS、Sentinel Nord（BriGHT、BOND）、DFO ROV脆弱海洋生态系统以及Kitikmeot海洋生态系统。
