Satellite Relay Tagging Program - Southern Ocean - MEOP Quality Controlled CTD Profiles

CTD (Conductivity-Temperature_Depth)-Satellite Relay Data Loggers (CTD-SRDLs) are used to explore how marine mammal behaviour relates to their oceanic environment. Loggers developed at the University of St Andrews Sea Mammal Research Unit transmit data in near real-time via the Argo satellite system. Data represented here was collected in the Southern Ocean, from both Elephant Seals and Weddell Seals. Data parameters measured by the instruments include time, conductivity (salinity), temperature, pressure and depth. The data represented by this record have been Qc'd and are the Australian subset of the MEOP-CTD database (MEOP: Marine Mammals Exploring the Oceans Pole to Pole), complemented with the most recent Southern Ocean deployment data. This Australian subset of the Southern Ocean database represents about one quarter of the entire MEOP-CTD database, which currently is about 52,000 profiles obtained from 275 CTD-SRDL tag deployments. The Australian dataset originated in 2004, and was initially collected by Mark Hindell's team based at the University of Tasmania, and in later years his data has formed part of the Animal Tracking Facility of Integrated Marine Observing System (IMOS).

CTD（电导率-温度-深度，Conductivity-Temperature-Depth）卫星中继数据记录仪（CTD-SRDLs）用于探究海洋哺乳动物行为与其所处海洋环境的关联。圣安德鲁斯大学海洋哺乳动物研究部研发的此类记录仪，可通过Argo卫星系统进行近实时数据传输。本次展示的数据采集自南大洋的象海豹与威德尔海豹。仪器所测量的数据参数涵盖时间、电导率（盐度）、温度、压力及深度。本记录所收录的数据均已完成质量控制（Qc'd，即Quality Controlled），属于MEOP-CTD数据库的澳大利亚子集（MEOP：Marine Mammals Exploring the Oceans Pole to Pole，即海洋哺乳动物跨极洋域探测计划），并辅以最新的南大洋部署数据。这套南大洋数据库的澳大利亚子集约占整个MEOP-CTD数据库的四分之一，当前该数据库总计包含来自275次CTD-SRDL标签部署所获取的约5.2万条剖面数据。该澳大利亚数据集始于2004年，最初由塔斯马尼亚大学马克·辛德尔（Mark Hindell）带领的研究团队采集，后续相关数据被纳入综合海洋观测系统（Integrated Marine Observing System, IMOS）的动物追踪设施中。
