Polar cyclones, intense atmospheric low-pressure systems, are responsible for the Arctic Ocean’s most extreme weather events and can have a profound impact on sea ice. Data: ERA-5. Animation: @oyvindocean Read more: instagram.com/p/DAIn35NPCpk/

🧵 The Nansen Legacy has come to an end today, 1 July 2024, after six years! 🤧 Thanks for following our journey. We have learned so much, and we have increased the understanding of the Barents Sea system considerably and hope you all learned something too! 1/2

@julzhh11 @OceanSeaIceNPI @NorskPolar Awesome! Gratulerer!

(How) does the ocean contribute to mass loss from the East Antarctic Ice Sheet? I have been working on this question over the past four years at @OceanSeaIceNPI, and today I submitted my PhD thesis ✅

@lavergnetho Thanks, Thomas! Yes, python/xarray/mpl/basemap. Will see if I can put the code in a gh repo after removing some internal dependencies🙂

Merry Christmas, global ocean circulation! Thanks for all your hard work - the North Atlantic wouldn't be the same without you. Animation: Daily sea surface temperature from HYCOM GOFS 3.1 #ocean #oceanography

The colossus has awoken. #Iceberg #A23a is on the move almost 40 years after it calved from the Filchner Ice Shelf. For nearly all the intervening time, it's been stuck in the Weddell Sea bottom-muds. It's now about to spill beyond Antarctica @BAS_News bbc.co.uk/news/science-e…

New @nansenlegacy paper in 𝑷𝒓𝒐𝒈𝒓𝒆𝒔𝒔 𝒊𝒏 𝑶𝒄𝒆𝒂𝒏𝒐𝒈𝒓𝒂𝒑𝒉𝒚 showcases the control retreating and melting sea ice has on the functioning of the northern Barents Sea system, with impacts on ocean, light, nutrient and phytoplankton dynamics. doi.org/10.1016/j.poce…

We are looking for a postdoctoral fellow @NorskPolar for sea-ice modeling in the @breathearctic project funded by @forskningsradet - application deadline 30 Sep - read the job announcement here: jobbnorge.no/en/available-j…

Scenic conditions in #Tromsø for a late night visit from Swedish icebreaker Oden @polarforskning @NorskPolar @OceanSeaIceNPI

Join our team! A three-year postdoctoral position on physical and chemical oceanography of the central #Arctic Ocean open for applications @NorskPolar @Framcentre - Deadline 31st March. jobbnorge.no/en/available-j…

And global sea-ice extent has now set a new *all-time* record low... ➡️ Arctic (2nd lowest on record for date) + Antarctic (lowest on record for date) [Graphics: zacklabe.com/global-sea-ice…. Data from nsidc.org/data/seaice_in… for the satellite-era. I am using a 5-day running mean.]

We @JentoftSissel, @BorgaK @nansenlegacy will organize a session - SS007 focusing on Impact of Climatic Change and Other Anthropogenetic Stressors on Polar Ecosystems, ASLO Aquatic Sciences Meeting, 4-9June2023, Palma de Mallorca, Spain Please retweet! aslo.org/palma-2023/ses…

Based on output from from the A4K ROMS model developed by Tore Hattermann and others at @norskpolar. Visualization inspired by @oceanographer.

Warm and swirly! The inflow of Atlantic Water transports heat, nutrients, and organisms to the Arctic Ocean. (Colors show modelled ocean temperature at 100 m depth)

Back ashore after a successful @nansenlegacy mooring and hydrography cruise! Helped by fair winds (mostly), zero sea ice, and fantastic people on an excellent ship. Always a relief to see those yellow buoys pop up on the ocean surface..

November 2019, northern Barents Sea. The ship travels through a sea of darkness and the air is biting cold. Below the sea ice, instrumented moorings observe something strange: warm currents are flowing in from the north... We explain what happens in a new paper in Ocean Science!

@NadjejdaEspinel @NorskPolar @Forskningsdg @Framcentre 🙂

@NorskPolar @Forskningsdg @Framcentre Well done @OyvindOcean !!

@adamdsteer Maybe you could run a boxcar filter over the sharp-edged one?
