The laboratory of Oceanology and Geosciences (LOG) is a Joint Unity of Research (UMR 8187) between the CNRS, the Université of Lille (UL1) and the University of Littoral-Côte d'Opale (ULCO).

The laboratory is mainly located in Wimereux, in the buildings of the Marine Station of Wimereux (SMW, UL1) and of Maison de la Recherche en Environnement Naturel (MREN, ULCO), but also a small part of the laboratory is located at the University of Lille1. The total number of people is around 120.

Le LOG a the particularity to federate scientists from differents scientific disciplines (biological oceanology, physics, sedimentology, geomorphology, geosciences) and its main research topic is on the oceanology and geosciences of the coastal and littoral domains. Because of its location (Wimereux), the main oject of studies is the oriental English channel (from the bay of Seine to the South of the North Sea).
This study site is considered as a model for the shallow megatidal seas. However, actions tale also place in other geographical sites, such as the coastal systems influenced by the Amazon River, in Latin America, Taïwan, Mediterranean Sea, Austral ocean, Vietnam and open ocean.
The laboratory is composed of Assistant, Associate and Full professors from the University of Lille1 and University of Littoral-Côte d'Opale and full-time junior and senior scientists froM CNRS.

The research activities are structured into 2 axis. Axis 1 is on oceanographic research and Axis 1 on geosciences. Inside both axes, 3 research teams as follows:

Axe 1 : Oceanology

Team 1: Diversity, processus and interactions in the marine ecosystems
Team 2: Ecosystems, biodiversity and global changes
Team 3: Remote Sensing and hydrodynamic

Axis 2: Geosciences
Team 4: Recent and current coastal dynamic
Team 5: Mineralogical and geochemical messages in the sediments
Team 6: Tectonic of sedimentary edges and basins
The team involved in the activitiees of the GIS is team 3 of axis 1 "Remote Sensing and Hydrodynamic", headed by C. Jamet (MCF ULCO). Its main research is focused on the experimental and theoretical analysis of certain physical components (speed field, light field, ...) to understand and then to forecast their impact on other physical, chemical and biological components that are carried in the marine medium. These studies are done from a multi-disciplinary approach, from a thematic point of view but also theoretical (model of turbulence, transport and radiative transfer) and experimental studies based on in-situ, laboratory and satellite measurements. At last, these researches are done following three topics: 1) Methodological and theoretical developments, 2) Study of the biogeochemical variability from time series of in-situ and satellite data, 3) Coupling between optics/physics/biogeochemistry for the study of the particulate dynamic in coastal medium.
