Objectives

Assess eutrophication evolution in the Mediterranean Sea over the last decade based on available historical remote and in situ information of eutrophication indicators.

Methodology

Freely online available data in public datasets of eutrophication indicators from the last decade was searched and collected to assess Mediterranean Sea eutrophication.

Eutrophication indicators or variables allowing estimating indicators were: surface chlorophyll pigment concentrations, nitrate, phosphate and dissolved oxygen concentrations, along with sea surface temperature and salinity.

Maps of chlorophyll concentration seasonal climatologies and trend, along with maps of average TRIX indices and TRIX trend were created.

Data covering the last two decades were processed only when data for the (target) last decade were limited and prevented estimating trends.

Data Sources

  • Sea surface satellite-derived chlorophyll pigment concentration in the water column (from Marine Copernicus).
  • Sea surface in-situ nitrate, phosphate and dissolved oxygen concentrations along with temperature and salinity data (from Emodnet, NOAA, Perseus FP7 project and MedAtlas).
