Research Abstract

We developed two clean analytical procedure for determining iron and aluminium concentrations in the sea ice. One is the method that removed contaminated outer layer of sea ice. The sea ice corer is collected by a lightweight filament tube with an aluminum cutting shoe and heat-treated steel cutting teeth. The outer layers of core were carefully removed using a ceramic knife to remove contaminated part during coring. The other method is comprised by ice meltar and in-line sampling and Fe analytical system. These method were applied to oridinary a sea ice collected from the Sea of Okhotsk.
