OBSEA

Expandable Seafloor Observatory

The main objective of this site located at Western Mediterranean is to be a test bed for the development of oceanographic instrumentation while being a shallow-water observatory providing real time data and database with historical values.

TNA

Obsea offers the possibility to deploy different types of measurement instruments, communication modules or scientific expermients, and allow real time communication with your deployment.

Devices can be deployed at 20m depth or at the surface buoy.

Obsea offers power supply, Ethernet and serial communications, and synchronization over PTP IEEE Std 1588. A continous realtime communication allows the tracing along the full experiment.

Avaliable for TNA Yes
Prefered time period for TNA Full year.
TNA Support offered A small boat and scuba divers are available in order to reach Obsea, deploy the instrumentation and plug it to Obsea.
Informatic team will support the communication with your instrument and the data quality control and different ouput formats for archiving.
Services Available Present instruments at Obsea are: CTD, seismometer, ADCP, meteo station, hydrophone and pH meter. Data comming from this instruments are fully available for the experiment.
Potential Additional Uses Hardware and software developpers of marine instrumentation and communications devices are invitted to deploy their systems at obsea to test performance, reliability and long term behaviour.
Data Ports Ethernet 10 /100Mbps and Serial link.
Availability of External Power 12 or 48Vdc up to 3 amps
Instrument installation methodology

By scuba divers.

Instruments and communicacion devices needs a specific GISMA series 10 size 3 wetmate connector to be able to connect to Obsea data ports. A custom adapter would be necessary to interface your insturments with Obsea data port.

Data History

Real Time data is available via direct connection to the instrument,  UDP or TCP socket with NMEA style data frames, DDBB, web interface, IEEE 1451 http server, or SOS servers.

Archive data is available via DDBB or netCDF files.

Instrument installation methodology Periodic dives to Obsea are executed for cleaning and revision of the deplyments every 4 weeks if there is any incident before.
Observatory maintenance estimated or planned schedules aproximately every 4 weeks
Data policy and access Data will be available free of charge. Reference to the source will be necessary when will be used for publications.
