Chlorophyll concentration exercise


This separate and rather scientific chapter allows you to determine the chlorophyll concentration of the seawater and hence monitor the health of the coastal waters and the open ocean.
 
From the report delivered by the student at the end of the cruise, we can extract the sea truth measurements made, and compare them with satellite observations.

All observations and measurements are contained in two tables, named:
  
 
MERIS image of Kerguelen Islands (chlorophyll colour)
   
MERIS image of Kerguelen Islands (chlorophyll colour)
 

  • Resultats-meteo.xls, which includes data on daily weather, sea and ice surface observations

  • Resultats-chimie-chlorophyll.xls, which reports on the measurements of chemical and chlorophyll concentration of seawater

 
 
 Working scientifically will need your full attention and quite some patience, since you also have to download, free of charge, specific software, and learn how to run it.
