EMSO Western Ligurian : MII, MICROCAT sensor (NetCDF files from 2017-09)

The European Multidisciplinary Seafloor and water column Observatory (EMSO) 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 deep water nodes plus four shallow water test nodes. EMSO Western Ligurian is one of these permanent underwater observatories located in the Ligurian Sea and is deployed off Toulon, France. This region was chosen for its particular scientific interests such as: seismicity, topography, turbidity, biodiversity, water mass dynamics and organic matter flow. This underwater observation network is also part of KM3NeT (https://www.km3net.org/) which has a modular topology designed to connect up to 120 neutrino detection units. Earth and Sea Science (ESS) instrumentation connected to KM3NeT is based on two complementary components: an instrumented interface module (MII) and an autonomous instrumented line (ALBATROSS). The ALBATROSS line is an inductive line (2000 m) composed of an acoustic communication system, two inductive cables equipped with Conductivity, Temperature, Depth (CTD)-O2 sensors, current meters and two instrumented buoys. This line is deployed at a distance of 2-3 kilometers from the MII, and communication on land is done by an acoustic link with the MII, and electro-optical cable via the KM3NeT node.

lineage=The infrastructure is dedicated to long term in situ observation. Based on instrumentation of the water column, this infrastructure aims at obtaining continuous in situ and near real-time measurements. This infrastructure MII (Interface Instrumented Module) is a cabled infrastructure and ALBATROSS (Autonomous Line with a Broad Acoustic Transmission for Research in Oceanography and Sea Sciences) is a standalone deep sea mooring dedicated to the long term monitoring of hydrological and biogeochemical properties. The data are transmitted in real time to the shore using the inductive cable along the mooring line and an acoustic link with the MII. This infrastructure has been developed by the DT INSU, to take into account surface ocean circulation (i.e. North Mediterranean Current, water mass dynamics including deep water formation, surface-to-bottom material fluxes and associated biogeochemical processes. Real Time data taking is operational since May 2019 for MII and August 2019 for ALBATROSS.

欧洲多学科海底与水柱观测站（EMSO）是遍布欧洲的海底和水柱观测研究基础设施。该观测站旨在进一步探索海洋，更深入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。观测站基于在欧洲海域战略性位置部署的观测站点（或节点），从北极到大西洋，从中东到黑海均有分布。目前拥有十一个深海节点和四个浅水测试节点。EMSO西利古里亚是其中之一，位于利古里亚海，部署在法国土伦附近。该地区因其独特的科学兴趣而被选中，如地震学、地形、浑浊度、生物多样性、水团动力学和有机物质流动。此水下观测网络也是KM3NeT（https://www.km3net.org/）的一部分，KM3NeT具有模块化拓扑结构，可连接多达120个中微子探测单元。与KM3NeT相连的地球与海洋科学（ESS）仪器基于两个互补组件：一个仪器接口模块（MII）和一个自主仪器线（ALBATROSS）。ALBATROSS线是一条感应线（2000米），由一个声学通信系统、两条配备有电导率、温度、深度（CTD）-O2传感器、流速计和两个仪器浮标的感应电缆组成。该线部署在MII 2-3公里的距离处，陆地上的通信通过声学链路与MII，以及通过KM3NeT节点的电光电缆进行。
