Decadal-scale variability in the upwelling of Upper Circumpolar Deep Water and its impact on primary production of the Southern Ocean 9th International Conference on Southern Hemisphere Meteorology and Oceanography/16th Australian Meteorological and Oceanographic Conference, Melbourne, Australia, February 2009, 2009 (Ref: 13742)
Category 3: Poster

The spatio-temporal variability in the upwelling of iron-rich Upper Circumpolar Deep Water (UCDW) is thought to have a significant impact on primary production in the Southern Ocean, since iron has been shown to be a limiting nutrient in an otherwise high nutrient region.
