🇦🇶 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. 💥

Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions
Iceberg calving accounts for about half of Antarctic ice-shelf mass loss. We used satellite imagery to analyze annual ice-shelf front changes and major calving events over eight years from austral sum...

Towards an improved understanding of the Antarctic coastal zone and its contribution to future global sea level
Understanding the coastal zone of the Antarctic Ice Sheet, where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate. Thi...

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.

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 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 🛰 💧
