Research Abstract

Iron (Fe) data in the water column and in the sea ice which were collected during sea ice retreat season indicate that the ice melting processes supply substantial Fe to the surface of the water column. These results clearly indicate that the additional Fe input from melting sea ice could be biologically important. Variability in sea ice dynamics are likely to result in a varying supply of Fe to the southern part of the Sea of Okhotsk in early spring, and to contribute to changes in the timing of termination and community composition of the spring phytoplankton bloom, especially around the Kuril Islands.
