🏆 [From the #Antarctic Treaty System to the ice memory heritage] Shipping of the Ice Memory ice cores to Antarctica are officially approved by the #ATCM! “In principle, we can start tomorrow to transport Ice Memory cores to Antarctica“ - Carlo Barbante vice-chair of #IceMemory

#Science onboard: FOREL's CTD-rosette is out of the water. The oceanographic activities of the GreenFjord project Swiss Polar Institute @swisspolar.bsky.social coordinated by Pr.

❄️ L’Arctique et l’Antarctique, pour en apprendre davantage sur les questions environnementales liées au réchauffement climatique et les enjeux stratégiques et géopolitiques en lien avec ces deux espaces aux pôles du globe : youtube.com/live/x1nmtvtlA…

"L’Arctique est la région du monde qui se réchauffe le plus" A l'occasion de notre série d'été en six épisodes sur le Svalbard, archipel qui concentre les grands défis contemporains, lisez notre entretien avec Chappellaz Jérôme shorturl.at/jtVEw Elodie Bernollin La Croix #Climat

À Estavayer-le-Lac, un énorme bloc rocheux amené par un #glacier, intrigue. Jérôme Chappellaz, #glaciologue et #climatologue EPFL, raconte l'histoire des blocs erratiques et leur importance pour comprendre les glaciers. rts.ch/audio-podcast/…

This summer, two teams from EPFL have visited the #Arctic. One to gain a better understanding of the air composition, the other to quantify the greenhouse gases sequestered in #Greenland fjords sourced by glacial water.

The « FOREL Greenland 2024 » expedition, initiated by the Forel Heritage Association, is coming to an end. FOREL docked at the port « La Base » in Lorient. The crew can now celebrate the success of this first mission before preparing FOREL for winter refit that lies ahead.

Red alarm 🚨 : the glaciers are melting not only in the two Poles but especially in the high mountains of the world. The project Ice Memory Foundation aims collecting ice cores from 20 endangered glaciers around tho world in 20 years.

Thanks to ice cores, scientists are mapping out how the Earth environment and temperatures vary over millennia. A repository for the ice cores is under preparation near the Italo-French Concordia station in #Antartica: a natural freezer with a temperature around minus 55°Celsius.

For all these years, it was just a name, a hope, a dream. Now the water stable isotope measurements confirmed that we have officially surpassed EPICA Dome C as the oldest continuous ice core record! We are truly Beyond EPICA! Merry Christmas to everyone! 📸F. Scoto©PNRA/IPEV

The drilling passed the depth of 2747 m and the processing is now only a few meters behind. Ice core boxes are being transferred to Mario Zucchelli Station. On January 2nd, the Australian MYIC team visited our camp and had some coffee and a cake (photo). 📸J. Westhoff©PNRA/IPEV

The Beyond EPICA ice core drilling has finally reached the bedrock at a depth of 2800 m: this is a huge success for our project and for ice core science! We have strong indications that 1.2 million years of climate record are stored in the uppermost 2480 m of ice. 📸©PNRA/IPEV
