The R/V Thalassa is an oceanographic ship mainly dedicated to the missions of public service in the field of fish stock assessment and physical oceanography.

The aim of this modernization is to enlarge the capacity of the vessel in the fields of marine geosciences and deep sea environment.

The objectives of the modernization are:• to ensure the remedial and curative maintenance at mid-life of the vessel,• to modify vessel accommodation• to replace all obsolete scientific equipment by up-to-date ones,• to provide a reliable and efficient platform appropriate to the coming 20 years of marine science,

Introduction


DescriptionCurrent cruises• Fisheries research (half time)

– population ecology,– assessment of fished species,– study of resource distribution over time and space,– fishery and product processing techniques.

• other capabilities– physical oceanography (OVIDES, PIRATA cruises)– deployment of the ROV, AUV– seismic surveys

Added capacities after modernization:– Bathymetry survey up to 4500m depth– Clean sampling (crane)– Marine biochemistry research– Understanding of evolution and geological hazards

Scientific equipment upgradeFisheries:

• EK60 EK80 (18, 38, 70, 120, 200, 333 kHz)

• 120kHz horizontal ranging

• new ME70 transducer(it’s the first one, will be 12 years old)

• Trawl monitoring system (Marport): no changes(Positioning, openings…)


Scientific equipment upgrade

Removed in sept 2016:• Deep water MBES EM302 Tx• Shallow water MBES EM2040• SBP• USBL



Adding:

• Sub-bottom profiler

• USBL for ROV/AUV + Acoustic release system (IXBLUE)

• MBES: EM302 0,5°x1°+ EM2040 0,4°*0,7°

• DVL (many systems currently in testing)
