ANTARES

ANTARES

Multidisciplinary, permanent marine observatory providing high-bandwidth real-time data transmission from deep-sea for geosciences and marine environmental sciences. Site is part of the MOOSE network providing real-time data transmission through two deep cabled moorings. These moorings are complemented by stand-alone mooring near the junction box. Physical and biogeochemical parameters recorded by autonomous sensors with regular maintenance. In addition monthly ship occupation for CTD profiles and seawater collection. Cabled extension of the neutrino telescope is offering connectors for direct link to shore in addition to operational seismometer already in place.

TNA

The TNA ANTARES concerns the access to the secundary junction box (BJS) and the inductive mooring which are part of the Ligurian EMSO network and the MOOSE network.

Avaliable for TNA Yes
Prefered time period for TNA During the maintenance cruises of the mooring and BJS
TNA Support offered Two types of support are proposed: the inductive mooring line (monthly) and the connection to cabled observatory (yearly).
The mooring (IL07) is composed with physical sensors (CTD, currents) and biogeochemical sensors (oxygen and IODA sensors). This mooring provides real time data through its connection to the seafloor cable (T, S, current and oxygen).
Services Available Logistical, technological and scientific support will be provided to access the ANTARES mooring and BJS.
Potential Additional Uses Additional sensors can be attached to the mooring line and the BJS.
Data Ports - 2 optical connectors, 3 ODI electrical connectors, one simplified electrical connector.
Availability of External Power On the cabled observatory: 2 optical connectors, 3 ODI electrical connectors (0.7kW, 300V), one simplified electrical connector (1.1kW, 300V).
Instrument installation methodology

Limitations with respect to some activities in order not to disturb the neutrino telescope  – Some cuts for neutrino telescope maintenance- Procedure (GUASA) for acceptance of branching

Data History
Instrument installation methodology Depending on instruments.
Observatory maintenance estimated or planned schedules Yearly or one week connection on the cabled observatory. More flexible for moorings.
