GEOTRACES mission is achieved through activities organized under three complementary themes:


themesTheme 1: Fluxes and processes at ocean interfaces

• Atmospheric deposition

• Continental run-off

• Exchange with sediments at the sea bed

• Exchange with sediments at the sea bed


Theme 2: Internal cycling

• Uptake/removal from surface waters

• Uptake/regeneration in the sub-surface ocean

• Seafloor regeneration

• Transport of TEIs by physical circulation


Theme 3: Development of proxies for past change

• Controls on water column distributions of proxies

• Uptake of proxies by sediment substrates

• Geochemical responses to sediment fluxes
