i2B Arctic Ocean Expedition 2025 Collecting new geological archives that will reveal past Arctic climate secrets

After 35 unforgettable days at sea, the i2B expedition has come to an end. The team retrieved nearly 250 meters of sediment cores from key sites across the #Arctic Ocean — records that will help unravel the story of past warm climates. 🔗 Read chief scientist Jochen Knies’ reflection: arcg.is/0favaf0

✨ The power of teamwork in the Arctic ❄️🚢
From hauling heavy cores to processing samples, every task on R/V Kronprins Haakon depends on collaboration. Read @alexgag11.bsky.social reflections on how teamwork makes science possible: 🔗 arcg.is/0favaf0

🚢 4 weeks at sea, 6,400 samples, and a record-breaking 22 m core ❄️🌊
The i2B team is piecing together the Arctic’s climate history, sample by sample — day and night.

💭 Read the reflections of @paleodyn.bsky.social PhD student @alexgag11.bsky.social, who traded screens for the Arctic Ocean. Aboard R/V Kronprins Haakon, he cut open sediment cores holding thousands of years of history and sampled water from 4000m below. 🚢❄️

In the meantime, I am sharing a few of my sea ice photos. I must admit, I got fascinated by the endless blue gradients.

i2B Arctic Ocean Expedition 2025 Collecting new geological archives that will reveal past Arctic climate secrets

On August 27th, I will share more about my duties on board through the expedition blog (arcg.is/0favaf0). I encourage you to follow it and also read the contributions from other expedition team members.

i2B Arctic Ocean Expedition 2025 Collecting new geological archives that will reveal past Arctic climate secrets

First week update:
We have been sailing day and night, moving east to west not far from the northern part of Svalbard. A few days ago, we reached the Yermak Plateau, where we carried out several measurements and collected sediment cores.

✨ Our first expedition blogs are now live! ✨

🚢 Step aboard the R/V Kronprins Haakon and follow the expedition team as they settle into life at sea and gear up to collect their very first long sediment cores from the Arctic seafloor.

i2B Arctic Ocean Expedition 2025 Collecting new geological archives that will reveal past Arctic climate secrets

And we're off! 🌟
Today the i2B Arctic Ocean Expedition embarks with 25 incredible scientists on its 35 day research cruise to the Arctic Ocean. We will collect geological archives that will reveal secrets of part warmer than present day climates!

The catalog is available at ar.pik-potsdam.de
We provide the data, examples scripts for downloading, and a lot of explanations.

Happy Pride Month! 🏳️‍🌈

At AWI, we are committed to diversity and equality. Pride Month in June reminds us how important it is to strengthen an open and respectful society, both in science and in everyday life. We embrace diversity every day.

Removing ENSO’s influence from global SST variability, with insights into the record-setting marine heatwaves of 2023-2024 Abstract The El Niño-Southern Oscillation (ENSO) is a dominant driver of seasonal-interannual climate variability and has been linked to record-setting extremes such as marine heatwaves (MHWs). Howeve...

Paper alert! 🚨

Ever wondered how ENSO contributes to Marine Heat Waves #MHVs? In the study conducted in collaboration with PhD candidate Alessandro Gagliardi (@alexgag11.bsky.social), the authors isolated the effect of ENSO in driving SST variability, including MHV extremes!

For the first time, it was also possible to wear a rainbow lanyard to show support for the LGBTQ+ community, which I proudly wore throughout the week.

See you at #EGU26!

I attended #EGU25 for the first time. It was an amazing opportunity to meet researchers from all over the world and to connect with many different research communities. I presented a poster and received a lot of constructive feedback and ideas for future work.

Thanks to all attendees & everyone presenting exciting research in last Friday‘s first-ever #EGU25 session on Atmospheric Rivers! See you next year! #atmosphericrivers

Climate extremes are a rising concern to Europe as they are projected to increase in frequency and magnitude in the future. But what about the past? Alessandro Gagliardi (@alexgag11.bsky.social) will present a poster at #EGU25 showing how ice cores are used to unveil past climate extremes!

Our Paleoclimate Dynamics group is now on Bluesky! Stay tuned for more updates on publications, the endeavors of our scientists and news on our events!

I am excited and grateful for the complimentary membership offered by the Royal Meteorological Society for 2025. Here is a picture of my welcome pack! I look forward to engaging with the community and sharing my contributions to the field.

The program included lectures on the geophysical principles of echosounding, hands-on training in data acquisition, storage, and visualization using QGIS.

It was an incredible seagoing experience, and I am deeply grateful to AWI and POLMAR for making this possible!

I have just returned from one of my dream experiences: being at sea on a research vessel! I traveled from Bremerhaven to the Canary Islands aboard the icebreaker Polarstern during expedition PS145/1, where I participated in the Echosounding Training Cruise organized by POLMAR.

Any paper that statistically validates the #Bromine enrichment in #Greenland ice cores as a proxy for sea ice? And maybe even that Bromine enrichment captures overall historical of #Arctic #sea #ice variability? Yes! Read our last work by @FedericoScoto

Yesterday I went to support the Werder Bremen women's football team. It was a good match with a fantastic last-minute goal! Go #Werderfrauen!

The outstanding scientific school on Ice Core Analysis and Techniques (ICAT) at the Niels Bohr Institute’s Physics of Ice, Climate, and Earth (PICE) in beautiful Copenhagen has just ended. I am eager to apply the knowledge I’ve gained to my research.
