The state
The ocean has a "long memory" compared to the atmosphere, and it is therefore feasible, at least a priori, to realistically predict ocean temperature much further ahead than the typical weather forecast. The prediction is complicated by the variation being governed by processes of both external and local origin operating on different time scales. Thus, both slowly moving advective propagation and rapid barotropic responses due to large-scale changes in air pressure must be considered.

There is large interannual and geographical variation in the distribution and abundance of phytoplankton species with in the area. However, the main pattern in the annual succession pattern is rather stabile despite variability in abiotic factors (e.g. temperature) between the years. The starting point of the spring bloom will vary between years, a variation that in large degree is controlled by t...

The horizontal distribution of mesozooplankton in 2008 is shown at the Figure 4.3.4. According to the joint ecosystem survey, the average zooplankton biomass was clearly below the long-term mean, and the spatial coverage revealed very low zooplankton biomass in the central parts of the Barents Sea – but with some scattered higher values recorded in the central part of the Barents Sea and along the...

During the PINRO atumn bottom trawl survey in 2007-2008, samples were collected as a basis for estimation of pre-spawning stock of euphausiids (Figure 4.3.7 A, B). The study showed that the abundance of euphausiids crustaceans was higher than the long-term means from the sampling area, and the arctoboreal species Thysanoessa inermis was the most dominating species.

The results showed a higher abundance of gelatinous zooplankton species in 2007 compared to 2008. This was particularly evident between longitudes 30-40ºE and 75ºN. In 2008, the highest abundance of gelatinous zooplankton was found more south and west in the Barents Sea than the previous year. Both in 2007 and in 2008, the distribution of “jellyfish” showed a considerable overlap with regions poor...

The abundance varied from 2500 – 38 500 individuals per m3 with a pronounced decrease in abundance eastward. Copepods were the dominating species in the samples with up to 90 % of total number of individuals. B...

The stations in the Fugløya-Bear Island (FB) transect are taken at fixed positions located at the western entrance to the Barents Sea. The numbers of sampled stations are normally 5 to 8 depending on the weather conditions. In this study, four stations, representing different water masses (coastal; Atlantic; and mixed Atlantic/Arctic water) in 1996 and 2007, were analyzed for species composition ...

C. finmarchicus was a dominant species among copepods on the Kola section, which is located further east of the Fugløya-Bear Island (FB) transect. Comparison of C. finmarchicus abundance and life stage structure are here studied in two relatively warm years (1983, 1992) and in an abnormally warm year (2008, Figure 4.3.12, Russian data). The results for 2008 showed that all C. finmarchicus stages, ...

Read more...The average mesozooplankton biomass in August and September 2008 for the Norwegian sector of the Barents Sea was below the long-term mean, and was in fact the lowest ever measured since 1997. The highest biomass was found in the Atlantic water masses which designate the importance of zooplankton transport from the Norwegian Sea into central and western parts of the Barents Sea. The continual decli...

The BarnetsPortal is a combined web site. It consist of two main elements; presentation of the Joint Norwegian-Russian environmental status report and the Map service. The Report will be updated at regular intervals - initially started with data from 2008. The Map service will continually publish environmental theme data as they become available. Read more...
More than 100 experts from a total of 9 Russian and 20 Norwegian institutions have participated in the preparation of the report, and the work has been organized in 13 expert groups. The work has been led by Sevmorgeo and PINRO on Russian side and on Norwegian side by the Institute of Marine Research and the Norwegian Polar Institute..
