MoMAR EMSO Azores
Multidisciplinary (fauna, fluid chemistry, seismicity and ground deformation) situated at the mid-Atlantic (hydrothermal vent field Lucky Strike); near real time communication through acoustic link, buoy and satellite. EMSO observatory node, in operation since 2010, comprises an oceanographic mooring and nested arrays of seismometers, pressure probes, temperature probes and chemical sensors in vent fluids, as well as a camera and colonization devices for faunal and microfaunal studies. Satellite transmission of a data subset, accessible on an EMSO-related server. Yearly maintenance cruises scheduled till 2015. Upgrades of system planned for 2014 with several new connection nodes accessible to FiXO3 collaborations.

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

| Instrument installation methodology | -Ifremer REM/RDT/I2M is in charge of the maintenance. Contacts are: Jérome Blandin (Jerome.Blandin@ifremer.fr) and Julien Legrand (technical supervisor - Julien.Legrand@ifremer.fr) - The yearly maintenance procedures including the ROV operations are under improvement since 2011. The upgrade of 2015 will correspond to a new version. FixO3 Best Practices workshops will provide oportunities to report and enhance. General principles can be found in the ESONET Label document ( download from http://www.esonet-noe.org/ ), waiting for the FixO3 Label document underway. |
