Marine Ecosystems and Satellite Observations

The video tutorial discusses the importance of microscopic marine algae, or phytoplankton, as the foundation of the marine food chain. It highlights the role of satellite remote sensing, led by the European Space Agency, in protecting coral reefs in the Red Sea. The tutorial offers online educational resources for high school and university students, teaching them to create maps and animations of phytoplankton populations. It also covers the use of bathymetry and coral reef databases to study reef distribution. The lesson emphasizes the significance of phytoplankton data for fisheries management.
