Ice algae are an important component of the carbon cycle in the Arctic, and can therefore have an impact on climate. I investigate the dynamics of an ice algae bloom by coupling an algae-nutrient model [Lavoie et al., 2005] with a thermodynamic sea ice model [Huwald et al., 2005]. The sea ice component is a more sophisticated model than what has been used in past Arctic ice algae model studies. To validate the model, I simulate an algal bloom at the base of the ice over a season and compare with data from the Resolute area in the Canadian Arctic Archipelago. Results suggest that bloom dynamics are strongly related to the ice growth/melt rate, with ice melt being the trigger for bloom decline. Being able to accurately mo...
