Objectif(s): To identify biological sources of organohalogens; to quantify their rates of release; to document their distributions in sediments, seawater, sea ice, snow and the lower atmosphere; to measure photosynthetic rates of ice algae, phytoplankton and/or seaweeds in relation to halogen emission, light quantity and/or quality; to determine the influence of ice algae on the radiation buget of sea ice.
Description du projet: Some natural gases in air react with light and can cause ozone depletion near the earth's surface. Some of these gases are produced by marine plants or algae such as seaweeds and the small single-celled plants causing "brown ice". The researchers will find out what marine plants which contain and/or release these materials called "organohalogen gases". This study will help to determine how much of these gases are natural versus man-made.
