Southern Surveyor Voyage SS 11/2004 Underway Data

This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 11/2004. The voyage took place in the Western Pacific ocean in the northern Tofua Arc, Tonga during October and November 2004. 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. The data are available at 10 second intervals in the NetCDF file, or at five minute intervals in the standard ASCII file.

本数据集包含航行中（Underway, UWY）实测数据，采集自“南方调查号（Southern Surveyor）”SS 11/2004航次。该航次于2004年10月至11月期间，在汤加北部托富阿弧（Tofua Arc）西侧的西太平洋海域开展。
本数据集已完成处理，存档于位于霍巴特的CSIRO海洋与大气研究数据中心。有关本数据集的更多信息可查阅该航次的航行计划文件与航次总结报告。
科研航次的标准航行中（Underway, UWY，即连续记录）数据集包含导航（Navigation, NAV）、测深仪（Sounder, PDR）、温盐廓线测量仪（Thermosalinograph, TSG）以及气象（Meteorological, MET）四类数据。
导航数据包含通过全球定位系统（Global Positioning System, GPS）获取的纬度、经度、船舶航向与航速信息。
气象数据涵盖大气温度、湿度、气压、风速、风向以及入射辐射强度等观测参数。
该数据集提供两种格式的分发版本：NetCDF格式文件的采样间隔为10秒，标准ASCII格式文件的采样间隔为5分钟。
