Sampling and analysis during 40S:
Aerosol and Rain sampling for major
ions and trace metals
Analysis for nutrients (NO3, NH4, organic
N, PO4) and trace metals
Analysis for δ15N of NO3 and NH4

Possible collaboration with Santiago
Gasso (NASA) on remote sensing of
Patagonian dust events
The Falklands is a good place to sample Patagonian dust events. Can
we fit a year of atmospheric sampling there into GEOTRACES?
