The soundscape in the Marginal Ice Zone

Submitted by Lasse Pettersson on 18. April 2016 - 11:26

The soundscape in the Marginal Ice Zone (MIZ) is comprised of seismic airgun noise, ship cavitation noise, and natural background noise due to different geophysical processes in the MIZ. Cavitation noise from the research ice-breaker dominated the sound scape at times.

Satellite archives reveal abrupt changes in behavior of Helheim Glacier at Greenland

Submitted by Lasse Pettersson on 9. March 2016 - 13:51

A new publication in Journal of Glaciology reveals the importance of internal dynamical process in the abrupt changes of the Helheim and other glaciers at Greenland during the last 35 years. Nansen Center and Bjerknes Center scientists Victoria Miles, Martin Miles and Ola M. Johannessen have published the paper Satellite archives reveal abrupt changes in behavior of Helheim Glacier, southeast Greenland.

Understanding why nights are getting warmer faster than days

Submitted by Richard Davy on 4. March 2016 - 12:45

GC Rieber Climate Institute

Observations from the last fifty years have shown that the nights have been warming much faster than the days. Analysis of the causes of this more rapid warming at night shows that this is likely to continue in the coming decades.

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

Submitted by Lasse Pettersson on 3. March 2016 - 12:50

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.

Måler temperaturprofiler over hele Bergen i dag

Submitted by Lasse Pettersson on 7. January 2016 - 12:20

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

Submitted by Lasse Pettersson on 5. January 2016 - 12:44

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?
