The role of remote sensing in oceanographic studies. Satellites used :Jason, Oceansat, Topeix-Poseidon,MODIS, AVHRR, SeaWiFS…

What is remote sensing? -Remote sensing using satellites. -Sonar systems -Radar

The gulf stream current A MODIS sea surface temperatures map

Detect Bloom of microscopic marine plants

Detect pollution in the upper level of the oceans

Visualise vortex created around the Canary Islands

Sea levelling, Altimetry

Hurricanes Forecasting

- A big tropical storm with strong winds - Low pressure and warm water are needed, - Wind power can be superior to 120Km/h What is a Hurricane ? Remote sensing via satellites provides to the scientists to forecast and modelize these natural phenomenon

Infra red

3 Dimensions

Modelization

Conclusion Remote sensing can be used to investigate : -biological productivity in the oceans -marine optical properties -the interaction of winds and currents, weather forecasting -how human activities influence the oceanic environment. Remote sensing has an important role in climate modelization
