Image and Instrumentation Pole (P2I)
P2I is a transverse platform of the IUEM that aims to facilitate research, training and observation missions by pooling scientific equipment and expertise and services in imaging and instrumentation in marine and coastal sciences.
The activities concern :
• The interdisciplinary use of remote sensing and marine instrumentation
• The coordination of equipment projects
• Shared management of equipment
• Methodological research
• Training in data acquisition, processing and analysis
• Expertise for instrumental qualification and data validation.
Since 2020, P2I has been involved in a quality approach in collaboration with the DT-INSU and the IRD (IMAGO unit) to guarantee and maintain the performance of equipment and ensure the quality and traceability of data.

Pôle Spectrométrie Océan
Pôle Spectrométrie Océan (PSO)
PSO concerns an innovative mass spectrometry devices package enabling trace chemical elements and isotopes analysis in geological and biological natural samples. The project associates UBO (IUEM), CNRS, Ifremer and IRD through complementary devices sharing specific to each organisation and devices acquired in common. PSO is a structuring tool for oceanographic research in the field of chemistry, biology and marine geochemistry carried out within the framework of the topics developed in IUEM laboratories through axes 3, 4 and 6 of LabexMER and EUR ISblue.
Devices located at IUEM are as follows:
