In Helsinki, combination of icy rain and #SaharanDust has formed a thin crispy brownish layer on the top of snowpack Ilmatieteen laitos Outi Meinander

Fun fact of the day - a full circle on the ice carousel at Tvärminne Zoological Station University of Helsinki takes one minute and twenty seconds :-)

Perfect conditions for afternoon coffee on the ice carousel Tvärminne Zoological Station University of Helsinki . 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. Music: Jonathan Streng

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

"Future is not one number, its a probability", stresses Jari Haapala from @FMI_Marine in his talk about SmartSea Project modeling studies. #FINMARI

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

Lumi ja jää, se inspiroi tutkijoita ja taitelijoita. Emil Cedercreutzin museo: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…

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

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

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

Really interesting concept to navigate in thick ice, does this reduce emissions Aker Arctic ?

Bothnian Bay Before the Breakup - stunning but very familiar satellite images of springtime sea ice. Also mentions two recent @FMI_Marine publications: earthobservatory.nasa.gov/images/148266/…

🌊👏📢READ OF THE MONTH 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…

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.
