Gratulerer med dagen, Fridtjof Nansen! His research inspires sea ice modelling today

159 years ago today, a legend was born: Fridtjof Nansen, a man who was not afraid to risk his life to prove that sea ice in the Arctic Ocean is drifting. His legacy lives on today, for example through the work we do at the Nansen Center in the Sea Ice Modelling group, which is connected to the Nansen Legacy project. I, Guillaume Boutin, want to take you on a journey to the Arctic and tell you about how Fridtjof Nansen’s research still inspires our research today.

 

Former MSc student Michael Hart-Davis wins S2A3 Masters Medal this year

During his MSc studies in South Africa, Michael Hart-Davis spent time at the Nansen Center in Bergen and was co-supervised by Björn Backeberg, Mostafa Bakhoday-Paskyabi  and Johnny A. Johannessen from NERSC and Juliet Hermes from SAEON, South Africa. His time in Bergen proved to be extremely beneficial and resulted in several international collaborations and publications and we congratulate Michael on this prestigious award!

 

Podcast with Igor Ezau – Heatwaves, the weather that can kill thousands in developed countries

Stephen Outten and Ingjald Pilskog host the Bjerknes Centre for Climate Research podcast and recently talked to Igor Ezau about heatwaves and their dangers. Don’t miss this episode!

 

Float Your Boat: Får skoleelever med i arktisk klimaforskning

Fridtjof Nansen lot polarskuta «Fram» fryse inn i pakkisen i Arktis for 127 år siden for å bevise hvordan havisen driver over Polhavet. I dag tjener mer enn 400 små håndmalte trebåter samme formål og driver gjennom Arktis på et isflak akkurat nå.

 


Hvem malte disse små trebåtene, og hvorfor er de der ute?

Greenland Ice Sheet and Arctic Mountain Glaciers get attention in new book

The Nansen Center Director, Sebastian H. Mernild, co-authored a chapter on the Greenland Ice Sheet and Arctic Mountain Glaciers in the recently published book “Arctic Hydrology, Permafrost and Ecosystems”. 

 

Geir Evensen receives the IOR award 2020 for his outstanding work on ensemble methods

He is awarded for his work based on the Ensemble Kalman Filter he developed as PhD candidate at NERSC in the 90’s and improved ever since. This data assimilation technique has found its way into various scientific applications.

2020 summer research school cruise: Useful Arctic Knowledge

In June, ten MSc students from the University of Bergen and the Western Norway University of Applied Science embarked on the coast guard vessel KV Svalbard to participate in the research school cruise near Svalbard, led by the Nansen Environmental and Remote Sensing Center. Their goal was to get hands-on experience during a scientific cruise in the Arctic.

 

 

Who were the participants?

Statsraad Lehmkuhl’s One Ocean Expedition: NERSC is onboard!

One year from now, the Norwegian tall ship Statsraad Lehmkuhl is setting sail for a 19 month-long circumnavigation of the globe. Sustainability and improving knowledge about the ocean will be the main focus. We, the Nansen Environmental and Remote Sensing Center, are excited to be joining part of this adventure!

 

Using satellites to investigate ocean surface currents along the Northern Norwegian coast

Researchers from NERSC, NORCE, the Norwegian Meteorological Institute (MET Norway), and the University of Bergen recently published an article in which they evaluate how well ocean surface currents in Northern Norway’s coastal areas can be studied with satellites, compared to traditional methods.

New Research Reveals Effect of Global Warming on Greenland Ice Melt and Consequences for 21st Century Sea Level Rise

New analysis of almost 30 years’ worth of scientific data on the melting of the Greenland Ice Sheet predicts global sea level rise of at least 10 centimetres by the end of the 21st Century if global warming trends continue.

The estimates, which scientists warn are “conservative” given the powerful effects of changes in weather systems and possible ways of accelerating ice loss, are broadly consistent with recent predictions reported by the Intergovernmental Panel on Climate Change.

CAATEX 2020 research cruise: Measuring the Arctic Ocean temperature below sea ice with sound

At this moment, the Norwegian Coast Guard icebreaker KV Svalbard is on a scientific expedition on the central Arctic Ocean with eleven scientists from different Norwegian and European institutions. Demanding operations are carried out to recover deep-water moorings deployed last summer. The moorings carry instruments to observe the ocean temperatures, salinity, ‘ocean sound’, carbon dioxide, and currents below the Arctic sea ice for one year. All this to calculate the ocean temperature below the sea ice. 


Scientific breakthrough: Winter climate in Norway now more predictable

Scientists from the Bjerknes Climate Prediction Unit, affiliated with the Nansen Environmental and Remote Sensing Center, the Bjerknes Centre for Climate Research, and the University of Bergen, contributed to a recent publication in Nature. The results indicate that it is possible to predict how the atmospheric circulation above the North Atlantic will evolve during the next decade. This is crucial for better predicting the winters in Europe and Eastern North America.

NERSC researchers and intern develop a smart way to classify sea ice types

A new paper published in “Remote Sensing” addresses sea ice type classification in a new and clever way: Combining machine learning and remote sensing. The first author of the paper is a former intern at NERSC who created the central algorithm within the three months he spent in Bergen, and thanks to it, classifying sea ice types might have become faster and easier!

Predicting Earth’s climate for the near future

The average temperatures worldwide will likely be higher in the upcoming five years than they have been in the past decades. This is one of the main results of a new report on climate predictions for the near future.

Nansensenterets direktør blir prorektor ved dansk universitet

Nansensenterets direktør Sebastian H. Mernild er ansatt som prorektor ved Syddansk Universitet (SDU) fra 1. oktober. Han har derfor sagt opp sin stilling som senterets direktør etter nær fire år i Bergen. 

The Nansen Center´s annual report for 2019 is published

The Nansen Center´s annual report for 2019 is now available as an interactive online book. In this format we hope the annual report will be more readable and easily accessible for the public. Enjoy reading about our scientific achievements in 2019.

Nansen Tutu Center 10-year Anniversary Symposium: “Ocean, weather and climate: Science to the Service of Society”

The celebration of the Nansen-Tutu Centre for Marine Environmental Research 10-year anniversary brought together around 80 researchers, Post Docs, PhD and MSc students for a 3-days symposium at the University of Cape Town conference center in Protea Breakwater Lodge, South Africa from 10-12 March 2020. Attendants came from Namibia, Mozambique, Madagascar, South Africa, Ethiopia, France, Germany, Norway, Netherlands and USA.

To studier publisert i Nature: Smeltingen av Grønlandsisen og Antarktis er seks ganger større enn på 1990-tallet

To studier publisert i det vitenskapelige tidsskriftet Nature viser at innlandsisen på Grønland og i Antarktis smelter seks ganger raskere i dag enn på 1990-tallet. Avsmeltingen nærmer seg det Internasjonale klimapanelet (IPCC) sitt øvre scenario for global oppvarming. Dette er bekymringsfullt og indikerer at de to iskappene også reagerer på et endret klima. Avsmeltingene kan føre til en ytterligere økning i globalt havnivået på 17 cm innen 2100. 


Book published: Sea Ice in the Arctic- Past, Present and Future

The book “Sea Ice in the Arctic - Past, Present and Future” gathers scientific knowledge and practical expertise’s in the sea ice research, monitoring and forecasting in the Arctic waters built up at the Nansen Centers in Bergen and St. Petersburg over the last three decades.
