9000
 data

of carbon export related to surface communities will be obtained thanks to the HOPE ‘Smart buoy'

11-15
 Bn tons

of carbon are stored in the ocean each year thanks to phytoplankton and the Biological Carbon Pump

50
%

of photosynthesis on earth (conversion of CO2 into living matter) is carried out in the oceans by phytoplankton

« HOPE's ambition is to study the role of our tropical and subtropical oceans in carbon sequestration, through an alternative pump operated by tiny plankton organisms called diazotrophs... »
