🇦🇶 Antarctica’s coastal zone is changing fast & it matters globally. A new #AntarcticRINGS review paper maps what we know, what we don’t & why it matters for sea-level rise. 🌊 Explore fresh insights, a Quantarctica-friendly data package & all figures as downloadable slides: scar.org/scar-news/cr...

🚨 Our new preprint! *Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions* 🔗 doi.org/10.22541/essoar.175285257.77669558/v1 In 2021, giant icebergs hit Dronning Maud Land ice shelves in #Antarctica, causing a chain reaction of calving & major regional ice-shelf area loss. 💥

Our review of the Antarctic coastal zone is finally available after 3+ years of work with 50+ institutes! We highlight data gaps & future priorities. Preprint here 👇 doi.org/10.22541/ess... #SCAR_RINGS #glaciology

This week some of our team are presenting new work at the ESA #LPS: 1️⃣ ice-sheet discharge using #RINGS airborne surveys covering nearly a quarter of the East #Antarctic coastline ✈️ 2️⃣ Rapid response of #Svalbard glaciers to ocean warming 3️⃣Satellite remote sensing of seasonal Arctic tundra changes

If you're interested in monitoring ice shelf calving front dynamics from @esa.int Sentinel-1, including small-scale frontal ablation, check out my poster today in the Dynamic #Antarctica session (A.09.02) 🛰🧊 #LPS25 #EarthObservation #Cryosphere @npiglaciology.bsky.social

Daga Wojtanowicz is one of this year's winners of Nature's #ScientistAtWork photo competition. Daga took this photo of James Bradley and Catherine Larose drilling an ice core to investigate how microbes + other life forms survive in the ice and adapt to the dark polar night. #glaciology #Svalbard

At EGU one of our team @antarcticjenny.bsky.social showed new work on ice-shelf calving front detection from Sentinel-1 🛰 to produce dense time series, revealing huge calving events triggered by iceberg collisions as well as small-scale changes important for field ops and 🚢 unloading.

Before glacier fieldwork in Ny-Ålesund, we train for crevasse rescue, avalanche safety & polar bear protection. This spring, Eirik Hellerud (NPI) led our safety week & route assessments on Kongsvegen & Holtedahlfonna. 📷: Wojtanowicz & Isaksson, NPI #NPolar #Glaciology

Yesterday our own Anirudha successfully defended his PhD thesis, 'Comprehensive Mapping and Climatic Assessment of Supraglacial Lakes in Dronning Maud Land’! Ani found that downslope winds warm and melt the ice surface for ponding, and found a link between these lakes and the Southern Annular Mode.

This year was the first-ever World Glacier Day! ❄️🌊 One of our glaciologists Jack Kohler shared insights on Svalbard glacier change for a seminar on the International Year of Glaciers' Preservation: 📊🌍

Today one of our glaciologists Jenny Arthur talked to 2nd grade students at Clover Ridge Elementary in Minnesota about her research, Antarctica from space and life in the Arctic ❄️ 🛰

NPI has contributed mass balance and satellite altimetry to a major study on the world's glaciers. This found glaciers lost 273 billion tonnes ice/year and had already contributed 18.1 mm to sea level rise. In Svalbard, glaciers have shrunk by 5%. lnkd.in/d62M3R9f Image: Samuel Martínez Llobet, NPI

📢 New book chapter out: 'Observing and Modelling Ice Sheet Hydrology.' 🛰 💧 If water on, within and under #Greenland and #Antarctica interests you, let me know and I can send you a copy! @npiglaciology.bsky.social (Will be fully publicly available once out in upcoming Cryospheric Science book)

Today is International Day of Women and Girls in Science! Meet the great women in our team: 👩‍🔬 Synnøve Elvehold, geologist 👩‍💻 Jenny Arthur, glaciologist 👩‍🔬 Katrine Husum, paleoceanographer 👩‍🔬 Elisabeth Isaksson, glaciologist 👩‍💻 Lotte Wendt, glaciologist. #Antarctic #Svalbard #PolarResearch

This week, two of our glaciologists Jack Kohler and Geir Moholdt are attending the TerraDT kick-off meeting in Helsinki, Finland. TerraDT will develop a #DigitalTwin of the #cryosphere, land surface and aerosols to improve the representation of these key 🌎 components. #glaciology #polar

New paper out from our team! Satellite observations of subglacial lakes are much needed for improving knowledge of subglacial meltwater dynamics and evolution, and for improving simulating these processes in models. #glaciology #Antarctic #remotesensing #hydrology 🛰 💧

Hi Bluesky! We are the glaciology team who work at the Norwegian Polar Institute in Tromsø, Norway. Follow us here on @bsky.app for insights into our polar #research on glaciers in Svalbard and Antarctica. We look forward to sharing updates with you! ❄️ 🥼 🛰 #glaciology #ice Photo: Kenny Matsuoka
