Breaking: Helsinki, Finland, has just recorded its lowest sea level on record, as a cold easterly flow and strong high pressure have pushed water out of the Baltic Sea. The observed minimum this morning was −93.5 cm below normal. The Helsinki tide gauge record goes back to 1904.

All Finnish icebreakers are busy assisting maritime traffic, and the #seaice on the #BalticSea continues to expand. If the Bothnian Sea becomes fully ice-covered this winter, it would be the first time since February 2011. Follow the daily ice situation at: en.ilmatieteenlaitos.fi/ice-conditio...

Drawing ice charts is fun, sometimes the ice polygons take some nice shapes, like this cute Ice Fox sitting on the Oulu fairway on today's #BalticSea #icechart.🦊😍 You can access the @ilmatieteenlaitos.fi ice chart at en.ilmatieteenlaitos.fi/ice-conditions

Such an obvious bi-annual event, but still sooo cool! =)

This winter's daily Baltic Sea #icechart :ing, done jointly by the Finnish and Swedish ice services, started today. The freeze-up is well under way in the Bay of Bothnia and the #icebreaking operation will quite likely start within a few weeks.

The long-awaited #Sentinel-1C satellite 🛰️ is now in orbit! So excited to pipeline its data to our sea-ice monitoring and the #BalticSea #icebreaking as soon as possible. www.esa.int/Newsroom/Pre...

Get your popcorn 🍿 ready. In Kemi the previous all-time low was recorded in 2016, back then reaching -128 below mean water reference.
