dc.description.abstractIn the Arctic Ocean, both phytoplankton and sea ice algae are important contributors to primary production and the arctic food web. An ice algal ecosystem model, which has been lacking in previous arctic ecosystem models, was added to fully couple with the global physical model POP-CICE (Parallel Ocean Program- Los Alamos Sea Ice Model) and the open-ocean pelagic ecosystem model. The physical model captured the seasonal and interannual variations of northern hemispheric sea ice extent and area measured by satellite remote sensing for the model period of 1992 to 2007. The model results showed a reasonable mean seasonal cycle of ice algal production from March to May and subsequent ocean production from May to September in the Arctic. The ice algal production, although smaller than that of the ocean, is of ecological importance as a food source for higher trophic levels during the long arctic winter before ice melt. The simulated mean open-ocean upper 100m primary production within the Arctic Circle was in the years 1998 to 2006, close to the remote sensing derived estimate of but with higher interannual variations. The mean sea ice algal production in the Northern Hemisphere from 1998 to 2007 was 21.3 T , which is in the range of multi-observational estimations of 9 to 73 based on in situ measurements. Model-data comparisons were conducted with various regional observations and the observed trend of temporal and spatial variation of the primary production. The model results compared well with the following observations and observed trends: 1) a similar increase of ocean primary production from 2003 to 2007 in the arctic open water areas as derived from remote sensing data-
