Henry Patton @rhewlif.xyz · 16/10/2026Results indicate the absence of beryllium input from the North Atlantic during late MIS6 and MIS4. The Arctic was thus effectively decoupled from the global ocean, implying major reorganizations of deep-water circulation and chemistry. 👉 doi.org/10.1038/s432... 073 7
Henry Patton @rhewlif.xyz · 16/10/2026In this latest study we tested this isolation hypothesis by measuring the reactive 10Be/9Be ratio in a suite of cores. This beryllium isotope ratio is a reliable water mass tracer that can reconstruct the dominant water inflows, from either from the North Atlantic or and from Arctic rivers. 130 3
Henry Patton @rhewlif.xyz · 16/10/2026Could an entire ocean turn from salty to fresh? It has been proposed that the Arctic Ocean and Nordic Seas were not only episodically covered by an ice shelf during past ice ages, but disconnected from the North Atlantic and filled with freshwater. 22011 20
Henry Patton @rhewlif.xyz · 08/10/2025Wow, that didn't take long to disappear! This was one of the glaciers I visited as an MSc student in 2006. 010 1
Henry Patton @rhewlif.xyz · 04/09/2025We dropped in on Santa Claus at the north pole this week to get our wish lists in early! To celebrate reaching 90N - the first time unaided for the Kronprins Haakon - we had ourselves a BBQ followed by a football match on the ice. 1191 19
Henry Patton @rhewlif.xyz · 25/08/2025One week into the @i2b-erc.bsky.social cruise and sediment cores are coming in thick and fast, guided by some fantastic sub-bottom profiler data. The question is, how old are these sediment layers? 051 5
Henry Patton @rhewlif.xyz · 16/08/2025An exciting expedition awaits! Our home for the next 5 weeks as we head into the frozen Arctic Ocean to collect new palaeo archives. 4231 23
Henry Patton @rhewlif.xyz · 04/05/2025Still a lot of snow across northern Norway - good for spotting the locations of old ice streams 😀 0233 23

Henry Patton @rhewlif.xyz · 21/03/2025The 2025 NORDQUA excursion will visit Gdańsk, Poland, 17-19 Sept. Three full days will cover the origin and evolution of glacial landforms, sediments and lakes, as well as processes of past and present coastal hazards in the Baltic coast. Sign up by the end of April! forms.gle/vZ4ECaVMxpfy... ⚒️ 031 3
Henry Patton @rhewlif.xyz · 26/11/2024Here in Kirkenes the sun set today for the last time this year. See you again in January! 🌄 040 4
Henry Patton @rhewlif.xyz · 12/11/2024A moment of tranquillity while sailing through broken sea ice. 2416 41
Henry Patton @rhewlif.xyz · 18/10/2024A simplified version of the Barents Shelf landscape evolution is also included on the interactive Icemap website at icemap.rhewlif.xyz 010 1
Henry Patton @rhewlif.xyz · 18/10/2024The power of ice...⚒️ Over the last 2.7 million years, ice sheets eroded ~3.7 quadrillion tons of rock from the Eurasian Arctic to create the Barents Sea we know today. 👀 Further erosion insights and timeslices ➡️ doi.org/10.1016/j.ea... 2389 38
Henry Patton @rhewlif.xyz · 02/09/2024I've noticed this figure of LGM extents gets re-used quite a lot in presentations etc. Since I was updating the map and its sources for another project, here is the latest iteration for people to enjoy ⚒️ 🗺️ doi.org/10.6084/m9.f... 032 3
Henry Patton @rhewlif.xyz · 15/08/2024#Methane release hotspots discovered in the central Barents Sea are releasing ~9,803 tonnes of CH4 per year into the water column Geological and glaciological controls show how these 21,700 natural seeps are likely to continue leaking. 📖 doi.org/10.3389/fear... 031 3

Henry Patton @rhewlif.xyz · 12/11/2023It's the end of a fantastic week on Svalbard teaching the Quaternary postgrads at UNIS about ice sheet reconstruction and modelling. It's been very inspiring to work with so many engaged students from all corners of the globe, and even the Aurora Borealis said hello. 161 6
Henry Patton @rhewlif.xyz · 12/09/2023Of all the glacial landforms in Fnjóskadalur, N Iceland, the Austari-Krókar delta is the most impressive ⚒️ Following the formation of an ice-dammed lake in the valley sometime around the Younger Dryas, glacial runoff produced this large delta, filling an 800 m-wide gap in the Ásar-esker below 0120 12
Henry Patton @rhewlif.xyz · 31/08/2023This week I got to vist perhaps Iceland's best kept geological secret - the Tjörnes section ⚒️ 🇮🇸 Here 14 cycles of glacial and interglacial sediments can be found dating back to 2.5 Ma, with each sequence subsequently preserved by a cap of lava 0197 19
Henry Patton @rhewlif.xyz · 25/08/2023Wonderful views of Vatnajökull while flying into Reykjavik today 🤩 050 5
Henry Patton @rhewlif.xyz · 22/08/2023Back in Trosmø and autumn feels closer. Plenty of mushrooms in the forest, plus some surprised reindeers on the summit of Njunnásčohkka, next to the Lyngen Alps 040 4
Henry Patton @rhewlif.xyz · 30/06/2023The Barents Sea, north of Norway, is younger than you probably think. New topographic reconstructions show that this shelf was still subaerial around 2.7 million years ago! Profound glacial erosion during subsequent ice ages reshaped this Arctic landscape into the marine setting we know today 🧪 150 5
Henry Patton @rhewlif.xyz · 28/06/2023Debris from WW2 still scatters the mountains around northern Norway. Last night we came across this wreckage, the remains of an Allied plane that was shot down over 80 years ago while it was attacking German shipping in Kirkenes. 010 1
Henry Patton @rhewlif.xyz · 31/05/2023How fast can ice sheets collapse? A rare beaded-esker system recently found on the seafloor in the Arctic suggests ice retreated here at rates of between 580-1600 m per year at the end of the last ice age. 👀 www.frontiersin.org/articles/10.338… 070 7
