The RV OGS-Explora is equipped to perform geophysical and oceanographic surveys both in shallow and deep ocean waters. Her capabilities include swath bathymetry, sub bottom profiling, 2D seismic prospecting, oceanographic measurements, moorings deployment and seafloor sediment sampling.
Onboard scientific equipment:
Echosounding: Hull mounted 18 kHz SBES Simrad EA-500;
Swath Bathymetry: Hull mounted 12 kHz MBES Reson Seabat 8150 for deep water surveys and 100 kHz MBES Reson Seabat 8111 for shallow water surveys. Sound Velocity Probe – Reson SVP 25;
Sub Bottom Profilling: SBP Benthos CAP-6600–consisting of 16 AT471 hull-mounted transducers, Sweep: 2-7 khz;
Multi Channel Seismic: 3 Built in, 4 stage, LMF compressors operating at 140 bar (capacity 23000 l/min each). Seismic Source: 2 Sercel GI guns (2*355 cu inch) for high resolution surveys; 1 Sodera Water Gun S16 (16 cu inch) for very high resolution surveys. Gun controller: Real Time Systems – Big Shot (16 channels)
Potential Methods: Bodenseewerk KSS 31 Gravity meter and Sea Spy Marine Magnetics Magnetometer / Gradiometer;
Oceanographic Equipment: Hull mounted RDI OS 75 KHZ Acoustic Doppler Current Profiler (ADCP), SBE21 thermosalinograph;
Sediment Sampling: Gravity corer (head 1.2 tons). Operation monitored by load cell controller Van Veen (max. core length 5 m);
2 meteorological stations.
Mobile scientific equipment on request:
MK21 Expendable Bathy Thermograph; 16 Sleeve guns for a total volume of 37 litres (2360 cu inch) and a 3000 m long digital streamer interfaced to a Sercel Seal recording system.
A satellite C Band VSAT system is operational on RV OGS-Explora allowing 24h/24h connection, Bi -directional file transfer (up to several Gbytes), live video streaming from ship to shore and real time XML data broadcast from ship to shore. This "Remote access" technology provides reasonable speed for sending real-time data back to shore-side researchers to accelerate and broaden data acquisition and processing. Thus significantly increasing the number of researchers who might benefit from a cruise. Please consider this option while writing your proposal for ship-time.
Availability for EUROFLEETS2:
Modality of access under this proposal: Successful applicants will be offered a 8 days shiptime in 2015/2016 at a suitable time in the vessel annual schedule in the North Atlantic area till the latitude of the Svalbard. Up to 12 people between scientists and technicians may be hosted on board. The vessel operates largely in Sub-Artic, Northern North Atlantic and Mediterranean Sea. Users will have full access to the infrastructure and scientific equipment.
Support offered under this proposal: full access to the infrastructure and scientific equipment. The scientific team will be supported by the OGS Explora technical staff, both during the mobilization and the execution of the cruise. Food and accommodation, lab space and power supply, communication, operational and logistic support will be provided.
