Primary production of ice algae and phytoplankton from December to June, in a fjord near Nuuk, Greenland, 2005/2006

LifeLinkedtoIce Algae and phytoplankton

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].

Communities of microscopic algae and other single-celled organisms, as well as the larger ice fauna, dwell in the saltwater-filled pores and channels of sea ice

As sea ice forms, droplets of water with high salt content form and these join into narrow “brine channels” that riddle the ice.

Cell concentration and number of microalgal species throughout a core of first-year ice from the Chukchi Sea, June 1998

LifeLinkedtoIce Cell concentration

 

 

The most numerous species identified in the core were ice-associated diatoms, but several different algal classes were represented. Microalgae were distributed throughout the core, but abundance and species composition varied with ice depth. The diversity was among the highest ever recorded in Arctic sea ice: 237 species were identified from the core. Depending on the species, the sizes of microalgae can range from a few micrometers to a few hundreds of micrometers.

Phytoplankton bloom in the southern Barents Sea, August 14, 2011 and relationship between timing of blooms and sea ice

LifeLinkedtoIce Phytoplankton bloom Barents Sea small

 

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.

The estimated global occurrences of these species within each category are shown within each pie chart (based on data including categorization from Kristinsson et al. 2010; n = 1,691, insufficient data for 59 of the 1,750 known species in the Arctic)..

Table 10.5. Numbers of potentially endemic lichens in the Arctic together with lichen species that are rare outside the Arctic, distributed by low and high Arctic, province or sector and their life form. Only species with known distribution are included (n = 358; endemic: 143, rare: 215). For explanation of province and sector, see Fig. 10.1.

Data on diversity of lichens and lichenicolous fungi in the Arctic and separately for the sectors of the Arctic (Beringia, Canada, North Atlantic, European Russia, W and E Siberia) and the single floristic provinces: numbers of species, numbers of species in the low and high Arctic, percentage of species with respective growth form (crustose, squamulose, foliose, fruticose), the estimated number of missing crustose lichen species (explanations below), percentage of species on the respective substrate on which the lichen species grow, and rarity of species within and outside the Arctic.

Trends in productivity derived from a 1982–2005 time series of GIMMS-G AVHRR vegetation indices (NDVI). Significant positive trends, showing as green, indicate an increase in both peak productivity and growing season. Negative trends, showing as red, represent forested areas not recently disturbed by fire that declined in productivity
