Will this decade be warmer than the previous one?

Ice algae and phytoplankton is the economic basis of the marine ecosystem in the Arctic.
Until now there have been few studies of the impact of reduced ice cover affects the major marine biological processes. Sea ice plays a major role in the primary producers aquaponics in the Arctic Ocean.
The Arctic spring bloom consists of two categories of primary producers: aquaponics algae that grow in and on the underside of sea ice and phytoplankton that grow in water.
Energy they ingest stored aquaponics in the form of liquid fat in a separate fat sack. It can represent a very large part of the animal when it is full. Arctic and feitåte may contain up to 80 percent fat, and is able to survive aquaponics up to two years without eating.
This is due to a combination of factors. Low temperatures lengthens development time. In addition, the ice melting aquaponics a strong stratification of the water which prevents the supply of nutrients to the upper layer. It provides a rapid decline in phytoplankton growth.
Calanus glacialis solves this problem by grazing on algae. Ice algae can start their blooming full two months before the phytoplankton. The reason is that, unlike phytoplankton, manages to grow even under poor lighting conditions.
During the International Polar Year, the Norwegian research project CLEOPATRA with researchers from UNIS, the Norwegian Polar Institute and the Alfred Wegener aquaponics Institute aquaponics in Germany, used a fjord system in Svalbard to follow the development of ice algae and phytoplankton.
The fieldwork took place in Rijpfjorden in 2007, an inlet at the north of the North Eastern Norway (Svalbard), which is directly linked to the Arctic Ocean. Data collection occurred using both a stationary ocean observatory and regular field work through the winter, spring and summer.
- The eggs thus managed to hatch and develop into the larval stage where they begin to eat within planteplanktonoppblomstringa in July, so they made full use of the other burgeoning fully, says Søreide.
- We will also include studies of how changes in the timing, quantity and quality of spring bloom also affects the rich benthic community that exists in the Arctic shelf areas, aquaponics says Søreide.

Until now it was believed that life in the Arctic Ocean has gone to sleep during the long Arctic night. New research now demonstrate that some of the key biological processes aquaponics simply does not stop during the dark months.
