Long-term observation of the marine ecosystems

The ocean has many impacts on human life, through its central place in many human activities, but also through its role within the climate system. It is now clear that the oceans have a close relationship with the climate through interactions with the lithosphere and the atmosphere.

So, in the face of rapidly changing climatic conditions, it is important to develop our knowledge of the temporal and spatial dynamics that characterize the oceans. To do this, only long series of measurements make it possible to describe the natural or disturbed evolution of a system with significant seasonal and / or inter-annual variability.

Regular observations over long periods of time have been and increasingly appear as an indispensable means of accompanying research. Indeed, for each of the natural environments, it is necessary to understand their fundamental functioning, to predict possible evolutions at different time scales.

Time series also enlarge our understanding of ecological processes and are integral for improving models of physical-biogeochemical-ecological ocean dynamics.

Mediterranean Institute of Oceanology is a research laboratory largely involves in the long-term observation of marine ecosystems, especially in the Northwestern Mediterranean Sea, but also in The South Pacific Ocean. The topics covered cover all the disciplines of Oceanography and therefore respond to the transversal aspect of this laboratory. 

These themes concern the anthropogenic impact on the marine environment and more particularly the coastal zone and the interfaces between the open sea, the continent and the atmosphere. Considerable effort in personnel and other resources are devoted to activities with the overall aim of monitoring the marine environments in both coastal and open waters.

The current works are to participate in national and international monitoring programs:

 

SOMLIT - MOOSE - COAST-HF - PHYTOBS - DYNALIT - ROMARIN - MOISE - SPOT

 

Observation data

The data sets are based on observations collected with systems deployed from ships or drifting devices, balloons, aircraft, fixed equipment on land or at sea and systems installed on satellites. These data can also be produced through campaigns at sea.
