[1/12] LONG FORMAT - Pour l’océanographe Jean-Eric Tremblay, la fonte au #Groenland bouleverse les fjords et leurs écosystèmes. La mission Cascades étudie ces effets en chaîne et la manière dont les changements océaniques peuvent, en retour, agir sur la fonte des glaciers. #geography #Arctic

Au plus près des fjords du Groenland pour comprendre les écosystèmes fragiles

Sur le brise-glace « Amundsen », une trentaine de scientifiques ont parcouru la côte ouest du Groenland en août pour étudier les effets du réchauffement climatique sur les écosystèmes des fjords. « Le...

Polarstern has returned from its final Arctic expedition of the summer, PS156 (LAMEX 1). For ten weeks, 40 researchers traveled more than 9,000 nautical miles from Tromsø to Greenland, the Fram Strait, the North Pole, and the Lomonosov Ridge. www.awi.de/en/about-us/... Video: Slingshot Pictures

A team of researchers has re-sequenced the genomes of 64 gentoo penguins from 10 breeding colonies spread across the Southern Ocean: gentoos are four separate species. One of the four, Pygoscelis kerguelensis, has been formally described for the first time. www.intelligentliving.co/new-penguin-...

First New Penguin Species in a Century Found on Kerguelen

Genomic sequencing has split the gentoo penguin into four species, including a new one on Kerguelen. Three of the four face habitat loss by 2050.

The newly recognised species, Pygoscelis kerguelensis, resides in one of the most isolated places on Earth – #Kerguelen Islands, located in the southern Indian Ocean. It looks virtually identical to any other gentoo, but is clearly genetically different. www.discoverwildlife.com/animal-facts...

Research represents evidence that the gentoo penguin is actually four genetically distinct species.

Permafrost is a vital part of the Arctic ecosystem. It stores carbon and provides stable, firm ground. When the ice melts, thermokarst lakes form. AWI researchers have now created the 'Lost Lakes' database, which contains information about the state of thermokarst lakes. www.awi.de/en/about-us/...

A Year in the Ice: The Tara Polar Station has begun its drift through the central Arctic!🧊🐻‍❄️On 9 September, the Tara Polar Station, reached its ice floe. From there, it will drift with the sea ice across the Arctic Ocean for a year. AWI scientist Julia Regnery is on board. www.awi.de/en/about-us/...
