Southern Surveyor Voyage SS 07/2004 Underway Data

This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS 07/2004. The voyage took place off the west coast of Tasmania in July and August 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“南方调查号”（Southern Surveyor）航次SS 07/2004采集的走航观测（Underway, UWY）数据。该航次于2004年7月至8月在塔斯马尼亚岛西海岸附近海域实施。本数据集已完成处理并归档，存储于霍巴特的澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）海洋与大气研究数据中心。有关本数据集的补充信息详见航次计划与航次总结文档。 科研航次的标准走航（即连续记录）数据集包含导航（Navigation, NAV）、测深仪（Sounder, PDR）、温盐仪（Thermosalinograph, TSG）以及气象（Meteorological, MET）四类数据。其中导航数据由全球定位系统（Global Positioning System, GPS）采集，包含纬度、经度、船舶航向与航速等信息。气象数据则涵盖大气温度、湿度、气压、风速、风向及入射辐射强度等参数。该数据集可通过两种格式获取：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。
