Prof. Daniel Sigman, co-author of the study "Iron Fertilization of the Sub-antarctic Ocean During the Last Ice Age" (http://www.princeton.edu/main/news/archive/S39/53/29A19/index.xml?section=topstories), talks with Vancouver's CBC Radio One host Gregor Craigie on the scalability and viability of boosting salmon populations in coastal water off of British Columbia.
Researchers from Princeton University and the Swiss Federal Institute of Techonology in Zurich have confirmed that during the last ice age iron fertilization caused plankton to thrive in a region of the Southern Ocean. The research confirms Martin's hypothesis, said Daniel Sigman, Princeton's Dusenbury Professor of Geological and Geophysical Sciences, and a co-leader of the study.
