Snow and ice changes in the Andes mountains during the last 70 years


The loss rate of Arctic land ice has increased threefold

New GEUS-led study shows the loss rate of Arctic land ice has increased threefold since 1986, from nearly 5000 tons of water per second during the “recent past” (1986–2005) to 14,000 tons per second in the present day (2005–2015).

"This is a solid scientific study that gives a temporal description of how the land ice in the Arctic contributes to the rising sea-level. The numbers are worrying as the loss of land ice from the Arctic has risen to three doubles in the period 1986-2005 to 2005-2015", says one of the authors Sebastian H. Mernild.

Film fra 1993 med fokus på fremtidens klimasituasjon

"Med bud om morgendagens klima" ble filmet under et av toktene i 1992 og produsert ferdig i 1993. I dag er det interessant å se hvilke perspektiver man hadde på klima for 25 år siden. En problemstilling som bare har blitt enda mer aktuell. Filmen er produsert og regissert av Carlo for Nansensenteret.

New podcast episodes

The Bjerknes Center and its partners; the University of Bergen, the Nansen Center, NORCE and the Institute of Marine Research, are collaborating on a new podcast that started earlier this fall. A total of seven episodes have been recorded so far at UiB in Media City Bergen. Currently, the podcasts have been in Norwegian, but soon English-language episodes will be produced. In these, Stephen Outten from the Nansen Center will be a moderator.

Agulhas Current meanders facilitate shelf-slope exchange on the Eastern Agulhas Bank

Agulhas Current meanders are some of the largest events that take place in the Agulhas Current system. They have a large impact on the shelf circulation and are important for the life cycle of several marine species. In an article published in Journal of Geophysical Research: Oceans two ocean models, as well as satellite observations, are used to examine how meander events change the way in which the Agulhas Current interacts with the continental shelf of southeast Africa.

The Chinese relations builder - portrait interview with Prof. Dr. Yongqi Gao

This autumn the Nansen-Zhu International Research Centre (NZC) in Beijing, China, and its partners celebrate their 15 year anniversary of rock solid science. Behind this successful collaboration between Chinese and Norwegian researchers one man stands out beside the initiators. Yongqi Gao, research leader at the Nansen Center in Bergen, has been a very important key person in this matter. Our Chinese colleague describes it in a slightly different way though. - I have been like a glue and filter in this collaboration, Gao illustrates.

At a time when social media loses its nerves on how variations of the Gulf Stream will melt the Arctic sea ice, two recent articles remind us that the proverbially warm Atlantic Waters have to cross the Nordic Seas and its complex ocean circulation. There is no way around them.
