NERSC Annual report for 2005 is now available

More than two decades of scientific expertise achieved at the Nansen Center within Arctic and sea ice research are timely relevant in relation to climate change and the increased activities in the Barents Sea and Russian Arctic shelf seas. Further details are found in our Annual report for 2005.
A major highlight in 2005 was the selection of the project “Climate and Environmental Change in the Arctic - CECA”, to the Laureates of the EU Descartes research prize in Earth Science for 2005. CECA was lead by Ola M. Johannessen, Lasse H.

Gulf of Mexico forecasts Version2 online

The Gulf of Mexico forecasts version are operational since 22nd March. They use the latest version of HYCOM and assimilate Sea Level Anomalies from 4 altimeters. The GOM v2 nowcasts and forecasts are more accurate than the previous version and should be useful for the offshore oil and gas industry.

New content and design of Algae Bloom and Water Quality Monitoring Service

The Nansen Center has redesigned its web-site for satellite Earth observation data on algae bloom and water quality information for the North Sea and Skagerrak region. The service is a part of the ESA GMES MarCoast Services Network - .

Our new front access shows the daily updated satellite image of the MERIS chlorophyll-a distribution (standard ESA algal-1 product) and sea surface temperature (MODIS SST). In addition average composites of the last seven days are made in order to reduce the impact of cloud cover in our waters.

Opening of the "Nansen House" in St. Petersburg

New offices for the Nansen International Environmental and Remote Sensing Center were opened Friday December 9, 2005 at the Vasilevsky island in St. Petersburg. Consul General of Norway Otto H. Mamelund inaugurated the “Nansen House” and unveiled a bust of Fridtjof Nansen. Fridjof Nansen is still very well-known in Russia for his humanitarian work during the famine.
The Nansen Center in St. Petersburg is an international research foundation employing 30 scientists and PhD-students.

The project "Climate and Environmental Change in the Arctic - CECA" wins the EU Descartes Prize for 2005 in Earth Sciences

CECA was one of the five "Laureates" of the EU Descartes Prize for 2005. The project leader was Professor Ola M. Johannessen from the Nansen-Mohn-Sverdrup Center/Geophysical Institute, University of Bergen (, with Professor Lennart Bengtsson, Max-Planck Institute of Meteorology, Hamburg, Germany ( and Dr. Leonid Bobylev, Nansen Center in St. Petersburg, Russia ( as partners.


Recent Ice Sheet Growth in the Interior of Greenland

In a paper published in the 20 October 2005 issue of Science Express, which highlights selected papers in advance of their publication in journal Science, recent growth in the interior regions of the Greenland Ice Sheet is reported by a Norwegian-led team of climate scientists. The growth is estimated to be about 6 cm per year during the study period, 1992–2003.

Article in Science

Influence of the Atlantic Subpolar Gyre on the Thermohaline Circulation.

In the Science issue of the 16th of September large and unexpected changes in the climate of the North Atlantic ocean are reported by a team of climate scientists from the Faroe Islands, Norway and Iceland. They show that the oceanic waters off Northern Europe are exhibiting record-high temperatures and salinities, and that these extremes relate to changes in the circulation of the North Atlantic circulation since the mid-90s.

Annual report 2004 is available

The annual report for the Nansen Center is now available at the web and distributed.


Biennial report 2003-2004 from NIERSC, St. Petersburg Russia

The Scientific Foundation “Nansen International Environmental and Remote Sensing Centre” (NIERSC) in St. Petersburg, Russia is a non-profit international research institution for environmental and climate research. It was founded in 1992. The major foci of the Centre are studies of Global Climate Change in the Arctic as well as Arctic environmental processes using satellite remote sensing, in situ data and numerical modelling.

Annual report for the Nansen-Zhu Centre in Beijing

The Nansen-Zhu International Research Centre (NZC), which is located at the Institute of Atmospheric Physics (IAP/CAS) in Beijing, is a non-profit joint venture between IAP/CAS, NERSC, the Peking University, Beijing, the University of Bergen, Bergen, and the Bjerknes Centre for Climate Research, Bergen. The institute is headed by Prof. Hui-Jun Wang at IAP/CAS, and Prof. Helge Drange at the G. C. Rieber Climate Institute, NERSC.

"White Sea - its marine environment and ecosystem dynamics influenced by global change" published by Springer-Praxis

Spinger-Praxis has just released the book "White Sea - its marine environment and ecosystem dynamics influenced by global change" by Nikolai Filatov, Dmitry Pozdnyakov, Ola M. Johannessen, Lasse H. Pettersson and Leonid P. Bobylev. The book is No. 3 in the Nansen Centers Polar Series and published with major contributions from the Nansen Centers in St. Petersburg and Bergen.

The book "The Nordic Seas - An Integrated Perspective" is now in press and will be available from July 2005.

The Nordic Seas comprise a small area of the world's oceans but contribute greatly to key climate processes and variations in the Northern Hemisphere and across the globe. As the site of the largest positive temperature anomaly among all the world's oceans, the Nordic Seas also allow scientists a place for research rich in detail, diversity, and implication.

Mye meso-skala variabilitet i den Nord-Atlantiske strøm

Nok et fargerikt bilde fra MERIS klorofyll fordeling med mye meso-skala variabiltet i havstrømmene vest for Irlannd og UK den 13 mai. Det er en stor utfordning å modellere "alle" disse hvirvlene!

Nordic Space focus on CryoSat

The first issue of Nordic Space in 2005 focus on "CryoSat and the climate".
Stein Sandven has written an article about the new satelites for monitoring the polar environment.

Satellitter overvåker vårens første algeoppblomstring langs kysten fra Skagerrak til Vestlandet

Den siste ukes god vær og solskinn var det som skulle til for å sette i gang årets første algeoppblomstring. I kystområdene fra Skagerrak til Stadt ser en i satellittbilde fra helgen (27. februar) en kraftig oppblomstring av alger i ytterst i vestlandsfjordene og i den utenforliggende kyststrømmen. Informasjon fra vannprøver bekrefter at dette er en helt normal, om enn noe tidlig, vårblomstring av alger.

Hva skjer ved klimaendring?

Heftig blir det diskutert i hvilken grad endringene i Jordens klima er menneskeskapt . Men hva vil skje når klimaet endrer seg, menneskeskapt eller ikke?
Her presenteres ti punkter som svar på denne problemstillingen.

Hva skjer med vinterværet?

Det er klare tegn på at havtemperaturen i Atlanterhavet om høsten, snødekket i Sibir og Tibet om høsten, og koblingen mellom atmosfærens øvre og nedre luftlag om høsten og vinteren er med på å styre utviklingen av stormer i Nord-Atlanteren de påfølgende par månedene. Les mer i dagens kronikk i Bergens Tidende.
