CSIRO O&A Marine National Facility Voyage Tracks Overview (1986 - present)

The CSIRO O&A Optimized Voyage Tracks displayed in the WMS associated with this record are derived from underway GPS data collected since 1986 by Australia's Marine National Facility during research voyages. For most of these voyages, five minute underway digital data is available. The underway data set typically includes GPS location, Sea Surface Salinity and temperature, and Meteorology Station data. Later voyages also recorded digital echo sounder data. Individual metadata records have been created for each research voyage. The data is held in the CSIRO O&A Data Warehouse, which currently holds underway GPS data for more than 200 voyages.

本记录关联的网络地图服务（Web Map Service，WMS）中展示的CSIRO O&A优化航次轨迹，源自澳大利亚国家海洋设施自1986年以来在研究航次中采集的船载实时GPS观测数据。多数此类航次可获取采样间隔为5分钟的实时数字数据。该实时数据集通常包含GPS定位信息、海面盐度、海面温度以及气象站观测数据。后续航次还新增了数字回声测深数据的采集。每个研究航次均已创建独立的元数据记录。相关数据存储于CSIRO O&A数据仓库，该仓库目前已收录超过200个航次的船载实时GPS观测数据。
