| Atmospheric deposition is one of the major sources of nutrients bringing trace metals to remote marine biota. In this study, total atmospheric deposition and crustal aerosol concentrations were monitored at Kerguelen Islands (49 degrees 18'S; 70 degrees 07'E) in the Southern Ocean during a short campaign in early 2005 and then continuously for about 2 years (2009-2010). Results show very low levels of atmospheric dust and trace metals concentrations but higher deposition fluxes than expected. The averaged total dust deposition flux as derived from Al deposition measurements is 659 mu g m(-2) d(-1). Simultaneously measured Fe and Co deposition fluxes are respectively 29 mu g m(-2) d(-1) (520 nmol m(-2) d(-1)) and 0.014 mu g m(-2) d(-1) (0.24 nmol m(-2)... |
