Impact of sea‐ice biology on overall primary production in a biophysical model of the pan‐Arctic Ocean

摘要: [1] The contribution of sea-ice biology and impact Arctic warming on overall primary production in a Pan-Arctic ocean model are investigated 57 year (1950–2006) simulation at coarse resolution using simple ecosystem model. The ice formally represents the growth aggregation micro algae into an ice-water interface, nearly undisturbed by surface mixed layer dynamics. importance this so-called ‘ice-algae’ stems from their significant to total (up 50% depending locations, according observations described Gosselin et al. (1997). Simple 1D tests reveal that, initial biomass light availability, can affect temporal variation nutrients, while they marginally production, or long term position nutricline. is found be as high 40% location 7.5% for whole Arctic. modeled negatively correlated September cover whereas more weakly positively correlated. Because negative correlation between sea pelagic short response continuing decline will increased seen model, would decline.
