EUs havovervåkningssamarbeide med Kina koordineres fra Bergen

Denne uken samles mer enn 20 forskere fra åtte kinesiske og fem europeiske institusjoner for å diskutere harmonisering av de operative system for havovervåkning og varsling for de to kontinent.

Nansen senter for miljø og fjernmåling (NERSC) i Bergen er vertskap for møtet og Forskningsdirektør Johnny A. Johannessen er koordinator for dette EU finansierte prosjektet ”DRAGONESS – DRAGON in support of harmonizing European and Chinese marine monitoring for Environment and Security System”.

GRL publication in press: Recent and future changes of the Arctic Sea Ice Cover

The interest in the Arctic Sea Ice seems inversely proportional to the area covered, and has exploded after the record minimum in September 2007, which were not beaten this year (see below articles). The Arctic ice has in many ways become the “canary in the coal mine” of global warming, but at the same time global models show a large spread in future predictions of the Arctic energy budget.

No new ice minimum in the Arctic in 2008

The drifting sea ice in the Arctic is an indicator of climate variability, which is caused both by natural and increased greenhouse gasses by human activities.

Last years record minimum ice area of less than 4 mill km2 compared to the average value of 6 mill. km2 over the 1979-2007 period, lead to speculation by many research groups that the ice cover in the Arctic had reached a tipping point and that it would disappear during the summer at a much earlier time than projected by the Intergovernmental Panel on Climate Change (IPCC) of the United Nations.

Arctic ice area for 2008 getting close to the extreme minimum of 2007

The ice area minimum in the Arctic happens every year in mid to late September, when the melting season in the Arctic is over. Even though the ice area today is about 100.000 km2 above last year’s minimum, both the Northeast- and Northwest passages are ice free, something that has probably not happened since before the last Ice Age, 100.000 – 125.000 years ago.

The Nansen Environmental and Remote Sensing Centre in Bergen, Norway continuously monitor the ice conditions in the Arctic using satellite observations. The Centre receives new satellite observations on a daily basis.

Ocean modeling of the Gulf of Mexico

François Counillon will defend his Doctoral thesis "Ensemble-based data assimilation and forecasting with an eddy-resolving model of the Gulf of Mexico" on Friday the 12th September at 13:15, at the Nansen Center/Geophysical Institute, University of Bergen.

The main objective of the thesis is to develop and validate a state of the art operational ocean forecasting system for the Gulf of Mexico region.

The thesis contains three referee publications on:

• Implementing a state of the art eddy resolving model for the Gulf of Mexico and analyzing the capability and limitations of the EnOI

Acoustic Monitoring of the Fram Strait

The Nansen Center and collaborating partners have this week launched an acoustic tomography experiment in the Fram Strait as part of the DAMOCLES EU project. The first acoustic source and receivers were successfully deployed on 15th and 16th August from RV Håkon Mosby with Dr. Hanne Sagen as cruise leader.

The tomography system will measure travel time of sound signals in different depths of the water column. The data from the array will be recovered during summer 2009 and be converted to a year-long record of temperature measurements across the West Spitzbergen Current.

Arctic Security - our Annual Report for 2007 available

Global warming is enhancing in the Arctic regions. The air temperature has increased to double that of the global average over the last 100 years, the ice cover is decreasing at a rate of 3 – 5% per decade while the thicker multi-year ice is decreasing at a rate of 7 – 10% per decade, the river discharge from Russia is increasing, the tundra-permafrost is thawing and the snow cover on land is decreasing. Furthermore, in the past few years the Greenland ice sheet has lost mass along its edges – more than the accumulation increase in the interior.

Favorable book reviews in EOS and Polarforschung

Pettersson, L. P. Bobylev, K. Kloster, V. G. Smirnov, Ye. U. Mironov and N. G. Babich , was published by Springer-Praxis in 2007 and in Russian language by Nauka in 2008.

Two Nansen Fellowship Ph.D. dissertations in Saint Petersburg

Dr. Natalia Ivanova has successfully defended her Ph.D. dissertation “Radar sounding of sea water pollution: theoretical modeling and practical applications”. The dissertation took place at the RosHydrometeorological University in Saint Petersburg on July 19. All the 26 members of the scientific evaluation committee unanimously approved her high quality research work that has been performed at the Nansen International Environmental and Remote Sensing Centre (NIERSC).

Pause i forhandlingene om nytt klima- og havforskningssenter

De respektive styrene ved Nansensenteret og Unifob AS har vedtatt å ta en pause i forhandlingene om et nytt klima- og havforskningssenter. Partene skal møtes igjen i januar 2009 for å gjøre en samlet vurdering på om man skal gå videre med forhandlingene.

- Vi har fortsatt stor tro på visjonen om et nytt klima- og havforskningssenter i Bergen, men konstaterer at tiden ikke er moden for å gå videre med forhandlingene på nåværende tidspunkt sier administrerende direktør i Unifob AS Arne Sivert Svindland.

Cosmoclimatology: The influence of Cosmic rays on Climate
by
Director Henrik Svensmark, Danmarks Rumsenter

Changes in the intensity of galactic cosmic rays alter the Earths cloudiness. A recent experiment has shown how electrons liberated by cosmic rays assist in making aerosols, the building blocks of cloud condensation nuclei, while anomalous climatic trends in Antarctica confirm the role of clouds in helping to drive climate change.

Norges Vitenskapsakademi for Polarforskning stiftet

Norges Vitenskapsakademi for Polarforskning (NVP) ble stiftet i Oslo 27. mars 2008 av 11 nåværende og tidligere polarforskere, alle professorer. Under stiftelsesmøtet ble det innvalgt en større gruppe nye medlemmer, slik at det totale medlemstallet er nærmere 50.

Formålet med det nye vitenskapsakademiet er som følger:

• Fremme forskning og utdanning om og i polare områder.
• Stimulere til nasjonalt og internasjonalt samarbeid og tverrfaglighet innen polarforskning.

Annual report from the Nansen Environmental Research Centre India

The Nansen Environmental Research Center India (NERCI) was established in 1999 as a joint venture between Indian and Norwegian partners. NERCI conducts basic and applied research projects in ocean sciences funded by national and international agencies, organizations and industry.

In 2007 the Centre focused on studies and modeling of the Indian Ocean.

Russian-Norwegian book on remote sensing of sea ice the Northern Sea Route published in Russian translation

In 1933 the Soviet Union started systematic studies and use of the Northern Sea Route (NRS) as a maritime route of transportation. The NRS has during the last 75 years had a major impact on the national ship transportation in Russia and other activities along the Siberian coast, but secure and efficient operations require great demands.

The Nansen-Zhu annual report for 2007 is available

The overarching goal of the Nansen-Zhu International Research Center (NZC) is to become an internationally acknowledged climate research and training centre with emphasis on tropical and high-latitude regions, and the interactions between these regions, for past, present and future climate.

The NZC is a non-profit joint venture located at the Institute of Atmospheric Physics under the Chinese Academy of Sciences (IAP/CAS) in Beijing, China.

Nansen Center contributes to new radar satellite technique sheds light on ocean current dynamics

Ocean surface currents have long been the focus of research due to the role they play in weather, climate and transportation of pollutants, yet essential aspects of these currents remain unknown.

By employing a new technique – based on the same principle as police speed-measuring radar guns – to satellite radar data (SAR), scientists can now obtain information necessary to understand better the strength and variability of surface current regimes and their relevance for climate change.

By using the new information embedded in the radar signal – the Doppler shift of the electromagnetic wav

Indo-Norwegian agreement on developing operational ocean forecasting for the Indian Ocean.

An agreement was today signed in Hyderabad at the Indian National Centre for Ocean Information Services between Norwegian and India partners. The aim of the cooperation is to develop an operational ocean modelling and data assimilation system for the Indian Ocean – the TOPAZ Indian Ocean forecasting system.
