Southern Surveyor Voyage SS2012_V04 Underway Data

This dataset contains the Underway (UWY) data collected on Southern Surveyor voyage SS2012_v04. The voyage took place from Fremantle to Fremantle in the Indian ocean between the 11th of August to the 5th September, 2012. The vessel was in port from the 14th - 23rd August. This dataset has been processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder, Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data includes atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data from "IMOS" (Integrated Marine Observing System) sensors are also included. The sensors are port and starboard radiometers and pyranometers, wind speed; rain and rainrate. Data are recorded at 5 second intervals and stored in NetCDF format. For Public Access data (.csv files, 10 sec and 5 min intervals). See "Download Public Underway data and Processing Reports" link for details.

本数据集包含"南方调查者号"（Southern Surveyor）航次SS2012_v04采集的走航数据（Underway, UWY）。本次航次于2012年8月11日至9月5日在印度洋海域开展，往返航线为弗里曼特尔至弗里曼特尔。该科考船于8月14日至23日处于港口停靠状态。本数据集已完成处理与归档，存储于位于霍巴特的CSIRO海洋与大气研究数据中心。有关本数据集的更多详细信息，可查阅本次航次的航次报告及/或数据处理报告。本研究航次的标准走航（即连续记录）数据集涵盖导航（NAV）、测深仪、温盐测量仪（Thermosalinograph, TSG）以及气象（MET）数据。其中导航数据包含GPS（全球定位系统，Global Positioning System）测得的纬度、经度、船舶航向与航速；气象数据涵盖大气温度、湿度、气压、风速与风向，以及入射辐射强度。此外，本数据集还纳入了IMOS（综合海洋观测系统，Integrated Marine Observing System）传感器采集的数据，包括左舷与右舷辐射计、总日射表（pyranometer），以及风速、降雨和降雨率相关监测传感器的数据。所有原始数据以5秒间隔进行记录，并以NetCDF格式存储。公开获取版本采用.csv文件格式，提供10秒和5分钟两种时间分辨率，详情请参见"下载公开走航数据与处理报告"链接。
