Origin of iron and aluminium in large particles (> 53 mu m) in the Crozet region, Southern Ocean
Natural iron fertilization processes are Occurring around the Crozet Islands (46 degrees 26'S-52 degrees 18'E), thus relieving the water masses from the normally encountered High Nutrients Low Chlorophyll (HNLC) conditions of the Southern Ocean. During austral summers 2004/2005 and 2005/20...
