Three successful meso-scale iron enrichment experiments
have been conducted in the subarctic North Pacific (SEEDS-I & II
and SERIES) over the last four years. This session will synthesize
the key findings of these experiments and initiate the development
of a common database. We invite contributions specifically comparing
and contrasting these three experiments. In addition, the unpredicted
response of a recent meso-scale iron enrichment experiment (SEEDS-II)
highlights our limited understanding of how iron affects biogeochemical
cycles, and the complexity of ecosystem responses to iron in High
Nutrient Low Chlorophyll waters. We also encourage papers investigating
how iron influences, and is in turn, influenced by ocean-atmospheric
exchanges, plankton activities and community structure, micronutrient
chemistry, and other processes in the subarctic North Pacific.
