Deployment of Argo Float ARVOR 6901913 September 2012

The Argo Float 6901913 was deployed on 14/09/2012 at 35.213 N, -27.689 W. The most current measurement was taken on 30/07/2017. The autonomous floats drift on the ocean currents for 10 days at 1000 m before diving to its profiling depth of 2000 m, taking ocean property measurements of temperature and salinity on its ascent to the surface. These two essential climate variables describe the oceans' physical and thermodynamic state. Once surfaced the data are transmitted via satellite. Marine Institute floats used ARGOS communications until 2017, and moved to Iridium communications in 2018 allowing for more information transmitted at faster rates with a two-way communication to the float. The Iridium communication means the float surface times are between 15-30 minutes instead of hours using ARGOS communication. The data are accessible online at Erddap (https://erddap.marine.ie/erddap/tabledap/argoFloats.html) and https://argo.ucsd.edu/data/. The Marine Research Infrastructures team operate and manage Ireland's contribution to Argo - a global array of autonomous floats or profilers, deployed across the world's oceans, reporting subsurface ocean water properties to a wide range of users via satellite transmission links to data centers. The Argo array is an indispensable component of the Global Ocean Observing System (GOOS) required to understand and monitor the role of the ocean in the climate system, in particular the heat and water balance. The International Argo programme currently has a network of approximately 4,000 Argo floats taking measurements in the oceans and is integrated into the Copernicus programme and the Global Earth Observation System of Systems (GEOSS). The Euro-Argo European Research Infrastructure Consortium (ERIC), which Ireland is a member of, aims to sustain 25% of Argo International's global fleet autonomous floats.Argo浮标（Argo Float）6901913于2012年9月14日在北纬35.213°、西经27.689°的海域布放。最新一次测量作业于2017年7月30日完成。该自主式浮标（autonomous floats）会在1000米深度随洋流漂移10天，随后下潜至2000米的剖面测量深度，在上升至海面的过程中采集温度与盐度等海洋属性数据。这两项关键气候变量可刻画海洋的物理与热力状态。浮标浮出水面后，会通过卫星传输采集到的数据。爱尔兰海洋研究所此前长期采用ARGOS通信系统（ARGOS），直至2017年，2018年起切换至铱星通信系统（Iridium），该系统可实现更高传输速率下的更多数据传输，并支持与浮标进行双向通信。相较于ARGOS通信需要数小时的浮出耗时，铱星通信将该时长缩短至15至30分钟。该数据集可通过以下在线平台获取：Erddap（https://erddap.marine.ie/erddap/tabledap/argoFloats.html）与https://argo.ucsd.edu/data/。海洋研究基础设施团队负责运营与管理爱尔兰对Argo计划的贡献：Argo计划是一套覆盖全球各大洋的自主式浮标/剖面仪阵列，通过卫星传输链路将次表层海水属性数据上报至各类数据中心，供广泛用户使用。Argo阵列是全球海洋观测系统（Global Ocean Observing System, GOOS）不可或缺的组成部分，是理解与监测海洋在气候系统中所扮演角色——尤其是热量与水平衡——的必要支撑。目前，国际Argo计划拥有约4000套浮标组成的观测网络，分布于全球各大洋开展测量工作，并已融入哥白尼计划（Copernicus Programme）以及全球对地观测系统之系统（Global Earth Observation System of Systems, GEOSS）。爱尔兰作为成员方加入的欧洲Argo研究基础设施联盟（Euro-Argo European Research Infrastructure Consortium, ERIC），旨在维持国际Argo全球浮标舰队中25%的自主式浮标保有量。
