@KnuuttilaS @SYKEinfo Näin on. Nyt kun jään päällä ei ole lunta niin noki yms ilman mukana jään päälle kertyneet, pilkkireikiin ja halkeamiin kertyneet hiukkaset erottuvat selkeästi.

Mönjää ei puske jään läpi, vaan kyseessä jokakeväinen ilmiö, jossa talven aikana ilmalaskeumana jäälle lumen mukana kertynyt noki valuu sulamisvesien mukana avantoihin. Noki on peräisin palamisesta energiantuotannossa ja liikenteessä, sekä lähialueilta että kauempaa. @SYKEinfo

Tummaa mönjää puskee jään läpi laajalla alueella Itä-Helsingin edustalla – aineen koostumusta tutkitaan yle.fi/a/74-20079518?…

Generating unstructured meshes for ocean modeling is always a challenge. Here's an example for the North Sea/Baltic Sea. Resolution has to be sufficiently high to resolve the coastal topography and the open boundary must be placed outside the shallow continental shelf sea.

The oceans are mixing much less than expected as a result of climate change. Read the following publication which shows how the ocean has become increasingly stable over the past 50 years. nature.com/articles/s4158…

Bothnian Bay Before the Breakup - stunning but very familiar satellite images of springtime sea ice. Also mentions two recent @FMI_Marine publications:

Really interesting concept to navigate in thick ice, does this reduce emissions @AkerArctic ?

One of the concept design projects we completed last year was the development of an ice-strengthened (#Arc5/#Arc7) semi-submersible heavy transport vessel (SSHTV). Read more in the latest issue of our #ArcticPassion News: akerarctic.fi/app/uploads/20…

Spectacular colorized footage from 1907 of the arrival in Helsinki of the Tarmo, a Finnish steam-powered icebreaker.

Massive pile-up of sea ice on the coast of Hailuoto island occurred during stormy day. BTW, two years ago, @MOSAiCArctic training was held exactly in this place.

Jos kirjoittaisin kirjan, jossa käsiteltäisiin kenttämatkoilla kyllästetyn tutkijan/tutkijoiden elämää, esim. "Retkikuntapäiväkirjat"-hengessä, niin kiinnostaisiko sinua lukea sellainen? #kirja #BUCKETLIST

This new implementation based on SI3 represents dynamics of coastal flaw leads extremely well. Congrats to developing team!

Sea ice is decreasing rapidly in the Gulf of Bothnia as the weather is getting warmer. Data from @FMI_Marine Nemo-Nordic forecast model. #seaice #balticsea #spring #oceanmodeling

Lumi ja jää, se inspiroi tutkijoita ja taitelijoita. @ECmuseo:lla on parhaillaan meneillään Espoon Taiteilijakillan "Vuo" näyttely. Geofyysikolla vuo tarkoittaa energian ja materian siirtymistä. Pidän aiheesta luennon lauantaina, ilmoittaudu m.facebook.com/story.php?stor…

Combined electromagnetic and laser measurements create an ice thickness data set. The results are compared to satellite images, improving ice remote sensing technologies.

This is amazing video even watch in my tablet but I'm really want to see this in some planetarium, hopefully in the @Heurekafi

Many planetariums remain closed due to #COVID. 😷However, you can watch the #planetarium show "Drifting #North - Into the #PolarNight" at home! A film by Amy Richman @CIRESnews @fiskeplanet Choose between dome version, #VR & 2-D version of the show! 👉 youtu.be/nAq9szCpWpY

Fun fact of the day - a full circle on the ice carousel at @Tvarminne @helsinkiuni takes one minute and twenty seconds :-)

Perfect conditions for afternoon coffee on the ice carousel @tvarminne @helsinkiuni . The carousel was created by Adrian Sundberg & Tapio Rautalin, without fossil fuels (handsaw!), giving us hope that there might be sea ice also in the future.
