EMSO-Ligure Ouest observatory data (mooring ALBATROSS) from 2014-09 to 2015-04

The European Multidisciplinary Seafloor and water column Observatory (EMSO-ERIC, https://emso.eu/) is a research infrastructure distributed throughout Europe for seabed and water column observatories. It aims to further explore the oceans, better understand the phenomena that occur on the seabed, and elucidate the critical role that these phenomena play in global Earth systems. This observatory is based on observation sites (or nodes) that have been deployed in strategic locations in European seas, from the Arctic to the Atlantic, from the Mediterranean to the Black Sea. There are currently eleven deepwater nodes plus four shallow water test nodes. EMSO-Western Ligurian Sea Node (https://www.emso-fr.org/fr) is a second generation permanent submarine observatory deployed offshore of Toulon, France, as a follow up of the pioneering ANTARES neutrino telescope. This submarine network, deployed at a depth of 2450m, is part of KM3NeT (https://www.km3net.org/) which has a modular topology designed to connect up to 120 neutrino detection units, i.e. ten times more than ANTARES. The Earth and Sea Science (ESS) instrumentation connected to KM3NeT is based on two complementary components: an Instrumented Interface Module (MII) and an autonomous mooring line (ALBATROSS). The ALBATROSS line is an inductive instrumented mooring line (2000 m) composed of an acoustic communication system, two inductive cables equipped with CTD-O2 sensors, current meters and two instrumented buoys. The MII and the ALMBATROSS mooring line communicate through an acoustic link. The MII is connected to an electro-optical cable via the KM3NeT node allowing the data transfer from and to the land based controlled room.

欧洲多学科海底与水体观测站（EMSO-ERIC，https://emso.eu/）是一个分布于欧洲各地的海底与水体观测研究基础设施。其目标是深化海洋探索，更好地理解海底发生的现象，并阐明这些现象在全球地球系统中的关键作用。该观测站以部署在欧洲海域战略位置的观测站点（或节点，node）为基础，范围覆盖从北极到大西洋、从地中海到黑海。目前共有11个深水节点和4个浅水测试节点。EMSO-利古里亚海西部节点（https://www.emso-fr.org/fr）是部署于法国土伦近海的第二代永久性海底观测站，是开创性ANTARES中微子望远镜的后续项目。该海底网络部署于2450米深度，是KM3NeT（https://www.km3net.org/）的一部分；KM3NeT采用模块化拓扑结构，设计可连接多达120个中微子探测单元，即数量为ANTARES的十倍。连接至KM3NeT的地球与海洋科学（ESS）仪器基于两个互补组件：仪器接口模块（MII）和自主系泊缆（ALBATROSS）。ALBATROSS系泊缆是一条2000米长的感应式仪器系泊缆，由声学通信系统、两条配备CTD-O2传感器的感应电缆、流速仪及两个仪器浮标组成。MII与ALBATROSS系泊缆通过声学链路通信。MII经由KM3NeT节点连接至光电电缆，实现与陆地控制室之间的数据传输。
