Southern Surveyor Voyage SS 02/2003 Underway Data

This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 02/2003. This voyage took place in Lau Basin and Tonga Trench-Arc system in the Pacific Ocean during March and April 2003. This dataset has been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the voyage plan and voyage summary. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder (PDR), Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data may include atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data are recorded at 10 second intervals.

本数据集收录了“南方探索者”号（Southern Surveyor）航次SS 02/2003采集的走航（Underway, UWY）数据。该航次于2003年3月至4月期间，在太平洋的劳盆地（Lau Basin）与汤加海沟-弧系（Tonga Trench-Arc system）开展作业。本数据集已完成处理，现归档于位于霍巴特（Hobart）的CSIRO海洋与大气研究数据中心。有关本数据集的补充信息可见于该航次的航行计划与航次总结报告。研究航次的标准走航（即连续记录）数据集包含导航（Navigation, NAV）、测深仪（Sounder, PDR）、温盐仪（Thermosalinograph, TSG）与气象（Meteorological, MET）四类数据。其中导航数据涵盖通过全球定位系统（Global Positioning System, GPS）获取的纬度、经度、船舶航向与航速信息；气象数据可包含大气温度、湿度、气压、风速、风向以及入射辐射强度。所有数据均以10秒为间隔进行记录。
