Hypothesis Bioactive trace elements control productivity from 30ºN to 30ºS in the Atlantic Ocean. The bioactive trace elements are intimately involved in various physical-biogeochemical feedback loops that influence our climate

Objectives Determine atmospheric inputs of bioactive trace metals through aerosol collection Determine deep water TEI supply from diapycnal mixing and upwelling (incl. turbulence measurements) Identify sources of TEI to the region through tracer measurements (Al, Ti, Mn) Establish natural microbial community structure Determine ammonium and nitrate uptake rates Determine nitrogen fixation rates Establish trace elements and nutrient streams through modelling
