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
