Deployment of Argo Float ARVOR 6901914 March 2013

The Argo Float 6901914 was deployed on 28/03/2013 at 38.437 N, -9.81 W. The most current measurement was taken on 12/03/2018. 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.编号为6901914的Argo浮标（Argo Float）于2013年3月28日在北纬38.437°、西经9.81°的海域布放。其最新一次测量于2018年3月12日完成。该自主式浮标会在1000米水深处随海流漂移10天，随后下潜至2000米的剖面测量深度，并在上升至海面的过程中采集温度与盐度的海洋参数数据。这两个关键气候变量可表征海洋的物理与热力学状态。浮标浮出水面后，数据将通过卫星传回地面。爱尔兰海洋研究所的浮标在2017年前采用ARGOS通信系统，2018年起切换至铱星（Iridium）通信系统。该系统支持以更快速率传输更多信息，且可实现与浮标的双向通信：相较于ARGOS通信需耗时数小时，铱星通信仅需15至30分钟即可完成浮标浮出水面的流程。相关数据可通过以下网址在线获取：Erddap（https://erddap.marine.ie/erddap/tabledap/argoFloats.html）以及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全球Argo阵列的贡献：该阵列是由分布于全球海洋的自主式浮标（或剖面仪）组成的全球观测网络，通过卫星传输链路向各类用户传回水下海水参数数据。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，该系统用于理解和监测海洋在气候系统中的作用，尤其是热量与水平衡。当前，国际Argo计划拥有约4000台布放于全球海洋的Argo浮标观测网络，并已融入哥白尼计划（Copernicus Programme）以及全球对地观测系统（Global Earth Observation System of Systems, GEOSS）。爱尔兰作为成员方的欧洲Argo研究基础设施联盟（Euro-Argo European Research Infrastructure Consortium, ERIC），旨在维持全球Argo舰队中25%的自主式浮标保有量。
