Location South of Azores latitude: 37.5, longitude: -33.00
Distance from Land
Max Depth 1700 m
Oceanographic features of area The Lucky Strike hydrothermal vent site has been selected for the integrated study of mid-ocean ridge processes, from the
subseafloor to the water column. It is set atop an active volcano, which hosts one of the largest active
ridge hydrothermal vent sites. The main scientific objectives are:
1- to study hydrothermal heat and chemical fluxes to the ocean in relation with seismicity, volcanic
activity and ground deformation at a diverging plate boundary
2- to study the impact of telluric, climatic and anthropogenic changes on deep seafloor ecosystems
and hydrothermal communities
3- to study the dynamics of water masses in relation to the steep axial valley topography, and their
impact on the dispersion of hydrothermal effluents.

TNA

On this EMSO Azores site, the
SEAMON system includes two nodes, both on top of the volcano near hydrothermal vents. One is
linked to geophysical instruments (a 3-components seismometer and an hydrophone for seismic event
detection, two pressure probes for geodetic measurements) and the other is devoted to ecology (a
video camera, a dissolved-iron analyzer, and an optode). The BOREL transmission buoy is equipped
with GPS (geodetic experiment and buoy location) and meteorological station.

TNA will consist in plugging additional sensors transmitting data in near real time and/or deploy additional mooring or autonomous benthic instruments.

Avaliable for TNA Yes
Prefered time period for TNA Only one cruise per year in summer season.
TNA Support offered At least two underwater connections are available for Fix03/TNA experiments on Seamon West. They
consist in free wet-mateable connectors providing 12V and an RS232 link to a host instrument. It is planned to offer more capacities on both Seamon east and Seamon west in the summer cruise of 2015.
Opportunities are offered for the deployment of water column moorings or autonomous benthic instruments during the maintenance
cruises.
Services Available Cruise preparation, compatibility tests, implementation on site, data transmission, archiving
and dissemination.
Potential Additional Uses Other services which might also be included on a case by case basis if found relevant by both observatory owner and TNA team and depending on budget agreement :
infrastructure to instruments software interfaces , onshore tests of
the marine equipment, participation to the cruise.
Data Ports -RS232
- starting in 2015, other interfaces will be available with either RS232 or RS485 allowing longer distance from the benthic node.
Availability of External Power Reference voltage is 12V.
The energy from the battery packs is allocated according to sampling frequencies. The management of energy on batteries will be performed by the technical supervisor during the year of deployment.
TNA equipments coming with their own energy are welcome.
Instrument installation methodology

In agreement with and complementary to the acceptance process of Fix03/TNA, an EMSO Azores
technical group will evaluate the technical feasibility of the proposals. It will include the agreements
by the Portuguese authorities  ;The users will be fully integrated in the cruise
preparations, in the interfacing of sensors on an electronic simulator. They will participate to the MoMAR meetings. Note that  cruises will take place in summer time starting in 2015, allowing two Trans National Access durations. The
preparatory work will start at least 6 months before the deployment cruise to provide time for
instrument integration plan (mechanical, electronics and driver software). The corresponding training
will take place at Ifremer Brest Center. In case of complex deployment procedure, a meeting with the
ROV team will be organized at IFREMER La Seyne sur Mer.

All equipments must comply with standard NF X 10 812 (http://www.boutique.afnor.org/) or equivalent.
