Laboratoire des sciences de l'environnement marin (LEMAR)

PLOUZANE

LEMAR is a resolutely interdisciplinary laboratory that brings together ecologists, biologists, microbiologists, biogeochemists, chemists, physicists and lawyers in the marine environment. Its objectives are: to conduct research on fundamental or socially important topics; to contribute to achieving sustainable development objectives in both northern and southern countries; to provide innovations in relation to the economic world and results in support of public policies; to engage in interdisciplinary training in the field of marine and coastal sciences.

Claire Hellio développe des solutions innovantes bio inspirées, à partir de molécules actives produites par les algues et les microorganismes. Mené au Laboratoire des sciences de l'environnement marin, ce travail de valorisation, à l'interface entre la chimie, la biologie, la biochimie et l'écologie, est notamment réalisé via la plateforme de bioprospection Biodimar, que Claire Hellio dirige. Les applications visent principalement les domaines des cosmétiques (antioxydants et…

On Lake Titicaca, between Bolivia and Peru, the Pachamama mission researchers study the changes and transformations of pollutants in order to better hinder their mutations and reduce their poisonous impact on the environment. They focused on methylmercury, the most toxic form of mercury. It poisons molluscs and small animals that feed on the biofilms present on the totora (reeds that have been exploited for centuries by local populations), then their predators, thus infecting every link in the…

Erwane Amice and Laurent Chauvaud, photographers and divers at the CNRS, discover the seabed near the French Antarctic base of Dumont d'Urville. They photograph the underwater polar fauna and flora which, in contrast to the surface, are very rich. In particular, they study scallops and date the marks on the surface of their shell, the chemical contents of the shell which are used as tracers to obtain information about sea water (salinity, temperature).
