RV Investigator Voyage IN2015_V03 Surface Velocity Program (SVP) Drifter Data

This record describes SVP Drifter deployments from the Marine National Facility RV Investigator Voyage IN2015_V03 and data access. This is the third research voyage for the RV Investigator departing Brisbane on the 3rd June and arriving in Sydney on the 18th June, 2015.The GDP (Global Drifter Program) SVP Drifters are Argos tracked Lagrangian Drifters designed to meet the need for accurate and global in-situ observation of Sea Surface Temperature (SST) and surface circulation. Each unit consists of a surface buoy and a subsurface drogue (sea anchor), attached by a long, thin tether. The buoy measures temperature and other properties, and has a transmitter to send the data to passing satellites. The drogue dominates the total area of the instrument and is centred at a depth of 15 meters beneath the sea surface. Manufacturer: Pacific Gyre Inc.A total of 10 drifters were deployed on this cruise, deployment information is provided in the documentation links below. Access to the data is via NOAA or system ARGOS.本数据集记录了澳大利亚海洋国家设施（Marine National Facility）“调查者号”（RV Investigator）研究船IN2015_V03航次中的SVP漂流浮标（SVP Drifter）布放作业与数据获取方式。该航次为“调查者号”第三次科考航次，于2015年6月3日从布里斯班起航，同年6月18日抵达悉尼。全球漂流浮标计划（Global Drifter Program, GDP）旗下的SVP漂流浮标是搭载阿戈斯（Argos）卫星跟踪系统的拉格朗日漂流浮标（Lagrangian Drifter），专为满足海表温度（Sea Surface Temperature, SST）与表层环流的精准全球原位观测需求而研发。每套设备均包含表层浮标与水下锚定浮筒（subsurface drogue，亦称海锚sea anchor），二者通过细长系绳相连。表层浮标可采集温度及其他环境参数，并配备发射机将数据传输至途经的卫星。该水下锚定浮筒占据了设备总表面积的绝大部分，其布设中心位于海表下方15米深度处。制造商为太平洋环流公司（Pacific Gyre Inc.）。本次航次共布放10台漂流浮标，详细布放信息可通过下文提供的文档链接获取。数据可通过美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）或阿戈斯（ARGOS）系统获取。
