L 'Atalante


RV L' Atalante is a multipurpose research vessel dedicated to research in marine geosciences, physical oceanography and marine biology. L' Atalante is currently used by scientists for a wide range of services at sea: by itself with it's on board scientific equipment and as support vessel for the deployment of sophisticated underwater systems as the submarine Nautile also available within this project. These combinations provide access to the sea surface, the water column and the sea floor, with a great variety of sensors allowing monitoring and sampling activities for a wide range of scientific tasks.

Onboard scientific equipment:

2 Multibeam echosounders: Deep water MMES Kongsberg EM122 1°x2°, shallow water MBES EM710 0.5°x1°;
3 Single beam echosounders ER60: 12 kHz, 38 kHz and 200 kHz;
2 Acoustic doppler current profilers: Ocean Surveyor 38 kHz and 150 kHz;
Scientific doppler velocity log, RDI 1200 kHz;
Subbottom profiler, Ixsea Echoes 3500;
Thersalinometer SBE21 with temperature sensor SBE38;
Standalone CTD profiler SBE19;
Towed magnetometer Marine Magnetics SeaSPY;
Bathythermograph Sippican;
Motion sensor Ixsea Octans;
Hull celerimeter Valeport MiniSVS.

Mobile scientific equipment on request:

Coring system; dredging; CTD profiler and rosette sampler.

Remote Access:

A satellite C Band VSAT system is operational on RV L'Atalante 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.

Nautile is a French manned submarine and a unique facility in Europe with only some counterparts in USA, Japan and soon in China and India. Its crew is of two pilots plus one scientist. Nautile provides direct viewing, via three portholes with a wide field of vision and eight foodlights providing colour range and restitution, video and still camera shots, object detection on panoramic sonar. Nautile provides also functional features as manipulation and sampling using two arms and an isothermal basket (retractable). Its in-vehicle positioning combine measurements of distance to beacons with position recognition made using the measurements of the submersible speed and attitude. It provides acquisition and recording on board the vehicle of navigational data and measurements taken by its sensors: altitude, pressure, temperature, heading, speed and time. Nautile provides also other functional features as preparing; monitoring, archiving and examining data with IFREMER developed software. Transmission in real time of data and pictures is possible. In the EUROFLEETS context, Nautile will be deployed from R/V L'Atalante.

Availability for EUROFLEETS:

The Nautile is NO LONGER AVAILABLE to the EUROFLEETS Project.

Technical Specifications

For the technical specifications please see the EurOcean European Underwater Vehicles InfoBase at:

Science support by crew:

Deck crew: 24h; technical support for onboard systems – winches, crane, full support for onboard science systems.

Availability for EUROFLEETS:

On board RV L' Atalante there are still 10 berths available to the EUROFLEETS project on an already funded EUROFLEETS cruise. This cruise will be 12 days long and will take place in September 2011. Investigation area is the vicinity of the Azores, and the port of mobilisation is Faial and port of demobilisation is Horta. Project applications making use of the spare berths are welcome. Please contact the EUROFLEETS Evaluation Office (eurofleets@awi.de) for further details.

Travel and shipment costs:

Travelling costs for cruise participants and the shipment of equipment to the port of mobilisation and back from the port of demobilisation will be reimbursed up to a maximum of 20.000€. If higher costs are incurred they have to be covered by the applicant.applicant.

Requirements for scientist:

Insurance; medical examination.
