Solubility of iron and other trace elements in rainwater collected on the Kerguelen Islands (South Indian Ocean)
The soluble fraction of aerosols that is deposited on the open ocean is vital for phytoplankton growth. It is believed that a large proportion of this dissolved fraction is bioavailable for marine biota and thus plays an important role in primary production, especially in HNLC oceanic areas where th...
