Objective(s): To identify biological sources of organohalogens and to quantify their rates of release and to document their distributions in sediments, water, sea ice, snow and the troposphere; to measure photosynthetic rates of ice algae, phytoplankton and/or seaweeds in relation to halogen emmission, light quantity and/or quality; to determine the influence of ice algae on the radiation buget of sea ice;

Project Description: The Researcher and his team will find out what marine plants (ice algae = brown ice or seaweeds) contain and/or release "organohalogen gases". The release of these gases is a natural source of pollution which has been going on for thousands of years. The research will identify various natural sources for organo and measure their rates of release in relation to normal growth processes.
