STACOT

Measured parameters

The Station Côtière’s activities initially focused on coral reefs on the island’s west coast. Today, the station’s perimeter is intended to extend to the whole of Reunion’s coastline, integrating other types of coastal environments.

The parameters measured and monitored by STACOT are multi-thematic:

  • Coastal morphodynamics
  • Physical, chemical and biological coastal oceanography
  • Marine water chemistry
  • Ecology and population biology
  • Visitor numbers and usage
