Description:
Autonomous floats profiling in high-nitrate low-silicate waters of the Southern Ocean observed carbon biomass variability and carbon exported to depths of 100 m during the 2002 Southern Ocean Iron Experiment (SOFeX) to detect the effects of iron fertilization of surface water there. Control and "in-patch" measurements documented a greater than fourfold enhancement of carbon biomass in the iron-amended waters. Carbon export through 100 m increased two- to sixfold as the patch subducted below a front. The molar ratio of iron added to carbon exported ranged between 10(4) and 10(5). The biomass buildup and export were much higher than expected for iron-amended low-silicate waters.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bishop, James K B -- Wood, Todd J -- Davis, Russ E -- Sherman, Jeffrey T -- New York, N.Y. -- Science. 2004 Apr 16;304(5669):417-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Earth Sciences Division, Lawrence Berkeley National Laboratory, 1 Cyclotron Road, MS 90-1116, Berkeley, CA 94720, USA.
