In-situ Data and Services Center OASU (Aquitaine Observatory of the Universe Sciences)

CDS-IS-OASU CDS-IS-OASU

The Aquitaine Observatory of the Universe Sciences (OASU) is a federative structure of the University of Bordeaux, the CNRS (INSU) and IRSTEA, joined in 2018 by the University of La Rochelle. It represents one of 28 Observatories of the Universe Sciences (OSU) spread throughout the national territory.

OASU brings together several independent laboratories working on long-term environmental observation topics (universe, land, ocean, atmosphere and coastal ecosystems) and the development of associated methodologies (instrumentation, data collection, definition of good practices, data analysis, modelling, data dissemination).  

In relation to long-term and high-frequency observation for the marine environment, OASU coordinates or participates in the "National Observation Services" (NOS/SNO) accredited by CNRS (SOMLIT, DYNALIT), the "Long-term Observation and Experimentation System for Environmental Research" (SOERE) accredited by AllEnvi ( Coast line) and observation tasks (SOLAQUI, MAGEST, MolluScan Eye). More information in the "Projects" tab below.

The Data Centre for Observation in New Aquitaine (CeDONA) is a federative structure between the various laboratories and teams that are part of the OASU. Its objective is to meet international standards for the provision of terrestrial and spatial data, to provide value-added services on these data, to be part of national and international infrastructures, for the thematic areas covered by OASU teams that cover a wide spectrum from the coast to the edge of the Universe.

All of OASU's CeDONA data processing services have made it a data and services centre of the ODATIS Ocean cluster.

Projects list

BENTHOSBenthos RESOMAR is a database of benthic marine fauna acquired in the various French marine stations and observatories in collaboration with the LEMAR (Brest) and LECOB (Banyuls-sur-Mer) labs.
DYNALITDYNALIT is a National Observation Service accredited by the CNRS INSU for the study of coastal dynamics and the coastline. DYNALIT manages the long-term acquisition, collection and consistency of quality metrological data from 30 worksites (sandy coasts, cliffs, estuaries) located on all French seafronts. The MAGEST stations are part of DYNALIT for the " estuaries " part. 
MAGESTA service that continuously monitors the physico-chemical quality, defined by the temperature, salinity, turbidity and dissolved oxygen of the Gironde estuary's waters. This regional network is made up of 7 stations spread from the Gironde estuary to the downstream of the Garonne, the Dordogne and the Isle. The coastal sites of the MAGEST network are part of the SNO DYNALIT.
Molluscan Eye
SOLAQUI
SOMLITNational Observation Service accredited by the CNRS INSU on the observation of the changes in the coastal environment. It currently includes 11 Marine Stations.
