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.

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.

ESF report: Remote Sensing of Shelf Sea Ecosystems - State of the Art and Perspectives

The Nansen Center contributes to the European Science Foundation (ESF) position paper “Remote Sensing of Shelf Sea Ecosystems - State of the Art and Perspectives”.

Leading scientist Lasse H. Pettersson was a nominated member of the ESF Marine Board working group writing the report.

MØTE AVLYST. pga. sykdom!!!!!! Cosmoclimatology: The influence of Cosmic rays on Climate

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.

Book: Remote Sensing of the European Seas

The Nansen Centers in Bergen and St. Petersburg contributes with two chapters in the book “Remote Sensing of the European Seas” ;

“Visible and infrared remote sensing of the White Sea bio-geo-chemistry and hydrology” by Dmitry Pozdnyakov, Anton Korosov and Lasse H.

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.
