Welcome to LEMAR

The LEMAR (Marine Environmental Science Laboratory) brings together biologists, biogeochemists, chemists and physicists with the aim of understanding and modeling marine systems within the biosphere, defining the characteristics of the environment and organisms, and decrypting their interactions. The unit promotes a resolutely interdisciplinary policy that is essential to address a complex area such as the interactions between the various components of the marine domain. The laboratory has a twofold connection with the CNRS: the Institute of Ecology and Environment (INEE), and the National Institute of Sciences of the Universe (INSU). He is also attached to the Department of Oceans, Climate and Resources (OCEANS) of IRD and to the Department of Biological Resources and Environment (RBE) of Ifremer. LEMAR is part of the European University Institute of the Sea (IUEM) of the University of Western Brittany (Université de Bretagne Occidentale - UBO). LEMAR is a major element of the Observatory which unites the components of the IUEM, which became the Observatory of Sciences of the Universe (OSU) in 2005. The unit is in particular in charge of several observation series of the coastal domain, in both the pelagic and benthic domains. UMR LEMAR is also co-pilot of axis 2 "Biodiversity and biological carbon pump" and axis 6 "Evolution of habitats and adaptation of populations" of the cluster of excellence LabexMer "A changing Ocean". LEMAR contributes greatly to the teaching of the Sciences of the Sea and the Littoral, within the Marine and Littoral Sciences SML Master courses, and the EDSM Doctoral School. LEMAR is mainly participating to the courses of biology and chemistry, and to that of ocean physics. Finally, the laboratory has been involved for many years in disseminating and popularizing scientific research on its own themes (marine environment, climate), and it is expected that this activity will develop more and more.

LEMAR is involved in major national and international scientific programs: INSU (LEFE, EC2CO), IGBP (IMBER, GEOTRACES, LOICZ, GLOBEC) and develops a firm policy of European integration following REX, EUR-OCEANS+ and MARINE GENOMICS. At the local level and beyond the PFOM unit, other Ifremer research units, three of which are also part of the IUEM (UMR LOPS, AMURE and LM2E), are privileged partners of LEMAR, with collaborations covering all the important research themes of the laboratory.

Since 2008, LEMAR hosts the former US CHRONOS of IRD, and the Marine Chemistry team of IUEM. In 2010 two more teams of IRD (the US ACAPELLA and the UR RAP) and several individual researchers joined LEMAR, increasing its staff from 43 to 70 permanent staff. In 2011, several researchers from the Laboratory of Ecophysiology and Biotechnology of Halophytes and Marine Algae (LEBHAM) and from the Laboratory of Chemistry, Molecular Electrochemistry and Analytical Chemistry (UMR CNRS 6521, CEMCA) of UBO joined LEMAR. Finally, LEMAR merged with the unit "Functional Physiology of Marine Organisms (PFOM)" of Ifremer in 2012. On January 1st 2017, the Laboratory had 120 permanent staff, with a total staff of 204.
