Plankton

Ice algae accounts for less than 1% of the annual primary production at this coastal location, but the bloom occurs at least a month before any primary production is available from phytoplankton. Farther offshore, ice algae contribute much more to the total annual production: as much as over 50% [4].

The number of species depends partly on what has been studied. Proportions vary somewhat around the Arctic, but diatoms and dinoflagellates are the most diverse groups everywhere. The greatest sampling effort has been in the Laptev Sea, Hudson Bay, and the Norwegian sector of the Barents Sea. Species shown are among the most commonly recorded.

The rate of change is very rapid at some locations. For example, the peak algal bloom occurred in early September in Foxe Basin and in the Kara Sea in the mid-1990s but had shifted to mid-July by 2009, a change of about 50 days.

The color in this satellite image is created by a massive phytoplankton bloom. The milky blue areas indicate a high abundance of coccolithophores, plankton that are plated with white calcium carbonate. Other colors may be from other plankton types and suspended sediment. The graphs, which are from a study over approximately the same area, show the relationship between the timing of blooms and the timing of sea ice. Diatoms (indicated by chlorophyll concentrations) dominate the earlier bloom that is associated with ice melt. Coccolithophores (indicated by calcite concentrations) dominate late summer bloom. They thrive in stable surface layers of warm, low-salinity, low-nutrient water. Coccolithophore blooms are becoming more frequent in the southern Barents Sea and expanding northward to the high Arctic.
All data shown are based on analysis of satellite imagery. This natural-color image was taken by the Moderate Resolution
Imaging Spectroradiometer (MODIS) sensor on the Aqua satellite.

Sea ice cover is represented in white in a). The vertical blue line indicates the time when the bulk of Calanus spp. biomass leaves the surface layer giving room for an additional peak in protozooplankton biomass.
