IMOS - Ships of Opportunity – Expendable Bathythermographs - Upper Ocean Thermal Data collected on the high density line PX34 (Sydney-Wellington)

Temperature data from the TOGA/WOCE transect PX34 across the Tasman Sea has been collected since 1991 and are ongoing. The transect is repeated approximately 4 times a year, with profiles obtained approximately every 10-50 Km. The data are obtained from XBTs (expendable bathythermographs) deployed via merchant vessels, and are managed by the Joint Australian Facility for Ocean Observing Systems (JAFOOS), a collaborative venture between CSIRO Marine Research and the Bureau of Meteorology Research Centre (BMRC).

自1991年起，科研人员便开始收集横跨塔斯曼海的TOGA/WOCE断面PX34的温度数据，该数据采集工作目前仍在持续推进。该断面每年约重复观测4次，剖面数据的获取间距约为10至50千米。本次数据通过商船投放的抛弃式温深计（expendable bathythermographs，XBT）获取，由澳大利亚海洋观测系统联合设施（Joint Australian Facility for Ocean Observing Systems，JAFOOS）负责管理，该设施是澳大利亚联邦科学与工业研究组织（CSIRO）海洋研究部与澳大利亚气象局研究中心（Bureau of Meteorology Research Centre，BMRC）的合作项目。
