Hydrobios-CTD data collected by the CCGS Amundsen in the Canadian Arctic

Provide core physical oceanographic data for all arctic research teams onboard the CCGS Amundsen and other interested scientists.The Hydrobios is equipped with Conductivity, Temperature, Depth (CTD) sensors recording temperature, salinity, and pressure data in the water column. This dataset is composed of CTD profiles and specific data for the volume of water going through the nets during their operation. CTD data constitute ancillary data for all other data recorded during the CCGS Amundsen scientific expeditions by providing information on the prevailing physical oceanic conditions in which biological, chemical and physical samplings were conducted. They also provide long-term records of the basic parameters central to the study of physical oceanographic processes, more specifically water column structure, water masses characteristics and oceanic circulation, in the Canadian Arctic Ocean. For some years, the data collection surpasses the Canadian Arctic border, however, the main goal of this project is to collect data from the Canadian Arctic Ocean.本数据集为搭乘加拿大海岸警卫队"阿蒙森号"（CCGS Amundsen）的所有北极研究团队及其他相关科研人员提供核心物理海洋学数据。Hydrobios系统搭载有电导率、温度、深度（Conductivity, Temperature, Depth，简称CTD）传感器，可记录水柱内的温度、盐度与压力数据。本数据集由CTD剖面数据与作业过程中网具过水量的专项数据共同组成。CTD数据可作为加拿大海岸警卫队"阿蒙森号"科学考察期间采集的所有其他数据的辅助支撑数据，为生物、化学及物理采样开展时所处的实际物理海洋环境提供详实信息。同时，CTD数据还可为加拿大北冰洋海域的物理海洋学过程研究提供长期基础参数记录，涵盖水柱结构、水团特征与海洋环流等核心研究内容。部分年份的数据采集范围已超出加拿大北极海域边界，但本项目的核心目标仍是采集加拿大北冰洋海域的相关数据。
