Abstract

The biomass and productivity of sea ice algae
was assessed in the northwestern Barents Sea in May
2004. Sea ice algal pigment content was patchy with a
mean of 18.5 ± 8.9 mg Chla m–2. The algal community
was dominated by the diatom Nitzschia frigida. Primary
production measured by 14C incubations was between
0.37 and 2.8 mg C m–2 h–1, which compared well with
oxygen-based methods using the diffusive boundary
layer approach (0.071–1.1 mg C m–2 h–1). Given the
differences in the irradiances under which these two sets
of measurements were made, there was a strong level of
consistency between the two sets of results. Measurements
of primary production were consistent with
previous Arctic measurements but high spatial heterogeneity
made a regional estimate of production inappropriate.
