Et sikkert vårtegn – framvekst av alger i Skagerrak og langs Sørlandskysten

I slutten av februar observerte forskere ved Nansensenteret store mengder alger i satellittbilder fra Skagerrak og langs kysten av Øst- og Sørlandet – HAB.nersc.no. Denne første vårblomstringen kom i år noe tidligere enn normalt, og er i tillegg også tilsynelatende mer massiv både i geografisk utbredelse og algemengder. Høye algekonsentrasjoner er observert i Kystrømmen fra Ytre Oslofjord til Farsund. En annen kraftig algeoppblomstring observeres i Boknafjorden i Rogaland.

Ensemble Kalman Filter workshop in Ulvik (Norway)

International Research Institute of Stavanger (IRIS) in collaboration with the Nansen Center (NERSC), the Uni Research CIPR (CIPR) and Statoil are organizing the 11th Edition of the Ensemble Kalman Filter workshop, 20-22 June in Ulvik, Norway.

Publication on Diurnal asymmetry to the observed global warming

Nansen Center scientists and partners have published a paper on Diurnal asymmetry to the observed global warming in Internatinal Journal of Climatology. This paper by Davy, R.; Esau, I.; Chernokulsky, A.; Outten, S. & Zilitinkevich, S. continiues a series of studies devoted to understanding of the role of the planetary boundary layer in the earth's climate.

Måler temperaturprofiler over hele Bergen i dag

Tobias Wolf @ Skolen 7. januar 2016.Nansensenteret har siden 2011 målt temperaturprofilen i luften opp til 1000 meter over Geofysisk institutt på Florida i Bergen sentrum. Instrumentet som er det eneste av sin type i daglig drift i Norge og gir i disse dager nyttig informasjon om temperaturinversjonen over Bergen sentrum. Inversjonen bidrar til at luftkvaliteten i flere deler byen blir helseskadelig høy.

Følger utviklingen av temperaturinversjon og luftforurensing i Bergen

Siden søndag kveld har det vært temperaturinversjon over Bergen. Slike temperaturinversjoner er de meteorologiske forhold som oftest fører til høy luftforurensing i Bergen. Meteorologene varsler fortsatt stabilt vær fram til torsdag, så vi kan forvente oss at luftkvaliteten er og vil forbli dårlig i dagene framover. Gjelder dette bare luftkvaliteten på Danmarksplass og i sentrum eller påvirker slike inversjoner også luftkvaliteten andre deler av kommunen?

US-Norwegian cooperation in ocean acoustics

Gaute HopePhD student Gaute Hope has spent the last month at the Woods Hole Oceanographic Institution at Cape Cod, U.S, to work on underwater acoustic communication signals and modeling.

Prof. Johnny A. Johannessen new Director

Prof. Johnny A. JohannessenProf. Stein Sandven has resigned from the position as Director of the Nansen Center. Vice-director Prof. Johnny A. Johannessen is accordingly the Acting Managing Director of the Nansen Center from today.

Climate data sets from satellites

ESA Climate Change Initiative is producing a number of climate data sets from satellite data. The climate variables are provided for the periods shown below. The following video shows excerpts of each data set.The Nansen Center is coordinator of the sea ice project and participant in the Sea Level, Ocean Colour and Ice Sheet projects.

Professor Jean-Pierre Contzen suddenly passed away

Professor Jean-Pierre Contzen (1935-2015)It is with great grief and sorrow we have to announce that Professor Jean-Pierre Contzen suddenly passed away in the morning of 27. October 2015, while he was attending meetings at the Nansen International Environmental and Remote Sensing Center in St. Petersburg.

New sea ice forecasts for the Barents and Kara Seas

The Nansen Center is pleased to announce that a new sea ice forecasting platform called neXtSIM-F is now up and running for the Barents and Kara Seas.

Forecasts are generated daily using neXtSIM-F on a 3km Lagrangian grid. neXtSIM-F is based on the sea ice model neXtSIM which is currently being developed at NERSC by the sea ice modelling group.

Investigating the possible causes for the recent warming hiatus

The IPCC stated in their latest assessment report that the global warming hiatus was attributable in roughly equal measure to natural variability and reduced trends in external forcing. A detailed study involving over 2000 years of model simulations has demonstrated that according to the Norwegian Earth System Model, there is no evidence that forcings errors play a significant role in explaining the hiatus. These results has been addressed in two papers lead by Nansen Center scientists Drs. Stephen Outten and Peter Thorne recently published in Journal of Geophysical Research.

Nansensenteret bidrar til ny rapport "Klima i Norge 2100"

Klima i Norge 2100Vann vil være en stor utfordring for Norge i framtiden, viser rapporten «Klima i Norge 2100», som ble presentert på Miljødirektoratet sin Klimatilpasningskonferansen i Oslo 22. september.

Challenges in sea ice retrieval methods using satellite microwave radiometers

Dr Natalia IvanovaSea ice concentration has been retrieved in polar regions with satellite microwave radiometers for over 30 years. Sea ice information providers, including EUMETSAT's OSISAF, ArcticROOS/Nansen Center, Copernicus OSI-TAC, NSIDC, University of Bremen and others, produce daily updates of the Arctic Sea ice area and extent.
