About us
Le Laboratoire Geo-Ocean – pôle UBS (anciennement LDO - GMGL - LGO) est une équipe de recherche en geosciences and eco-management of marine, coastal and littoral environments located at the University of Southern Brittany à Vannes. L’équipe Geo-Ocean UBS fait partie de l' Mixed Research Unit (UMR) 6538 CNRS and fonctionne en partenariat avec l’équipe GO – IUEM UBO. Since its creation in 2000, the laboratory has become an expert in the study and management of marine, coastal and coastal environments, and their past, current and future evolution in France and internationally. Multidisciplinary research is carried out in geomorphology, geochemistry, paleontology, oceanography, numeric modelling, risk and vulnerability, ecology and spatial planning.
For 20 years, our researchers have forged numerous partnerships with various other laboratories, universities, private companies, collectivities and associations from Brittany to the international scale. We strengthen these collaborations everyday by getting involved and supporting multiple projects.
Our main activities
The laboratory has 3 main activities :
La RESEARCH
In order to better understand the environmental aspects of coastal and marine environments, our researchers, engineers and technicians carry out regular field campaigns to collect and analyze long-term data. The results then allow us to improve our current knowledge of these environments, ultimately to predict and help communities make appropriate land-use planning decisions.
La EDUCATION
L'équipe GO intervient au sein de la Licence S.V.T du parcours Sciences de l'Environnement et pilote le Master Ingénierie Côtière. Ces deux formations pluridisciplinaires permettent d'acquérir des connaissances fondamentales et des compétences techniques. Elles conduisent à des métiers de techniciens et ingénieurs dans les domaines des sciences de la mer et du littoral.
L'OBSERVATION
L'observation consiste à s'intéresser à des données dynamiques (sédiment, qualité de l'eau, hydrodynamisme, trait de côte...) sur le temps court ou le temps long. L'équipe GO dispose d'une base de données SIG de plus de 20 ans sur la dynamique sédimentaire (plateau continentale, estuaire, baie), et a récemment mis en place en 2017 un Observatoire citoyen (OCLM) alimenté par les sciences participatives à l'échelle du Morbihan.
Research fields and expertise services
The LGO UBS works in 6 different scientific fields :
Measurement and analysis of hydrodynamics, morphological and sedimentary characteristics of the different types of coast (beaches, cliffs, mudflats, ports, estuaries ...). in situ des différents types de côte (plages, falaises, vasières, ports, estuaires...).
COASTAL AND MARINE SEABED SEDIMENTOLOGY
Analysis of the nature and morphodynamics of the seabed (evolution of sand banks, sequential stratigraphy...).
REMOTE-SENSING AND PHOTOGRAMMETRYTRIE
Acquisition and processing of UAV images for topographic and photodynamic studies.
Satellite images processing for Suspended Matter studies, sediment flows and vegetation monitoring.
COASTAL AND MARINE SEDIMENTS GEOCHEMISTRY
Evaluation of heavy metals and Metal Trace Elements levels in sediments in ports and natural environments. Carrying out probing at the water-sediment interface.
QUALITY OF COASTAL ECOSYSTEMSÈMES CÔTIERS
Sampling in situ et analyses en laboratoire d'échantillons d'eau, de sédiments et de phytoplancton permettant d'évaluer la qualité d'un milieu (présence de métaux lourds, quantité de nutriments, taux d'O2...).
Reconstruction of paleoclimates, paleoshoreline and paleoecosystems using bioindicators (pollens, foraminifera ...). Analysis of the current climate and predictions of future climates and sea level rise.
