Bio-optical model of Antarctic sea-ice algae photosynthesis. Antarctica contains no permanent human population; however the impact of climate change is being observed. Sea-ice is slowly becoming less thick and covering smaller areas of the Southern Ocean. Algae grow on the underside of this sea-ice which feed krill, which in turn support most of the Antarctic food web. Understanding how changes in sea-ice and snow thickness will change the productivity of Antarctica will have significant implica ....Bio-optical model of Antarctic sea-ice algae photosynthesis. Antarctica contains no permanent human population; however the impact of climate change is being observed. Sea-ice is slowly becoming less thick and covering smaller areas of the Southern Ocean. Algae grow on the underside of this sea-ice which feed krill, which in turn support most of the Antarctic food web. Understanding how changes in sea-ice and snow thickness will change the productivity of Antarctica will have significant implications to our management of this wilderness. Knowledge of how sea-ice algae responds to changes in light can be incorporated in climate change models.Read moreRead less
Effect of Global Change on the Primary Production of Antarctic coastal Ecosystems. As the climate warms, sea ice in Antarctic coastal areas will reduce. Most primary production currently occurs within the sea ice. We propose that a reduction in ice extent will lead to a reduction in ice production but greater benthic production; phytoplankton production will stay relatively constant. These changes will significantly effect the size of pelagic (ie fish) and benthic (starfish, sea urchins etc) st ....Effect of Global Change on the Primary Production of Antarctic coastal Ecosystems. As the climate warms, sea ice in Antarctic coastal areas will reduce. Most primary production currently occurs within the sea ice. We propose that a reduction in ice extent will lead to a reduction in ice production but greater benthic production; phytoplankton production will stay relatively constant. These changes will significantly effect the size of pelagic (ie fish) and benthic (starfish, sea urchins etc) stocks, which in turn will impact on the size of seal and penguin populations. Our project will allow predictions of these changes that have been induced by a reduction in sa ice extentRead moreRead less
