Comparison of sea ice and seawater biomass and productivity. Temporal development of (a) sea ice integrated primary production in mg C m−2 day−1 (blue bars), integrated Chl a in mg m−2 (green bars), NOx concentration in µM (black circles), PO43- concentration in µM (black triangles) and O2 bulk concentration in µM (orange squares) and (b) under-ice and open water integrated primary production in mg C m−2 day−1 (blue bars), integrated Chl a in mg m−2 (green bars), NOx concentration in µM at 1 m (black circles), PO43- concentration in µM at 1 m (black triangles) and O2 bulk concentration in µM at 1 m (orange squares). The data points represent the average of triplicate samples; error bars indicate SD of the mean.
