The sea ice factory: the North water polynya has a very far northern boundary in the Kane basin this year.

🌊 The interconnection between sea ice and our #atmosphere is magnificent, and polynyas are vivid representations of it! Our #nextGEMS calendar brings you a spectacular piece of #ScienceArt capturing the magic of polynyas. 🗓️ Our May calendar page, crafted by Thomas Rackow, unveils the breathtaking sight of a #polynya opening in the Canadian Arctic.

🔍 What's a polynya, you ask? It's a fascinating phenomenon in #oceanography — a pocket of open water amidst sea ice, often found in polar regions

Cold Case: Scientific Sleuths Solve the Case of the Mysterious Giant Opening in Antarctic Sea Ice

Researchers have discovered the missing piece of the puzzle behind a rare opening in the sea ice around Antarctica, that occurred during the winters of 2016 and 2017. It reveals a key process that had eluded scientists as to how the opening, called a polynya, was able to form and persist for several

The Ice Bridge: A Haven for #Seabirds in Pikialasorsuaq

"In early spring, when ice still covers most of #BaffinBay, millions of #birds migrate north to the open waters of #Pikialasorsuaq, a huge #polynya between #Greenland’s west coast and #Canada’s #EllesmereIsland, where they feed and raise their young. Pikialasorsuaq is a very special area. It’s the most productive open water in the #Arctic"

The Ice Bridge: A Haven for Seabirds in Pikialasorsuaq

In the second part of our series on the North Water Polynya, we look at the millions of birds that travel here each year.

did a radio podcast thing for our #Antarctic voyage - it was a great conversation (Sharon Brettkelly was so on to it) but I rambled as usual - the team at Radio NZ crafted a great (and dare I say important) story. And our PhD student Liv just aced it with enthusiasm to counter my school principal vibe. #DoYourSelfaFavour #climate #oceanography #polynya

That was somehow to be expected. Let's see how long this area stays free of ice. Very interesting season!

some soothing, if icy, video from our team's most recent voyage aboard the Korean Icebreaker Araon - A change in route meant I had to stand this one out but wow... #Antarctica #Polynya #Drone #KOPRI #NIWA #ASP and this is all gonna change... https://vimeo.com/827083865/489c720dd5

thinking of my colleagues aboard the Korean #Icebreaker IBRV Araon as it looks to thread its way north through a bit of a maze of #SeaIce. Pretty thrilled that they got to deploy our sampling gear amongst all this and get some sneaky opportunistic sampling in too! Strange to be dealing with this in anticipation of a time with much less ice... 😞 #Polynya #Antarctica [img: https://go.nasa.gov/3FDomJQ ]

today was the day I was meant to head into quarantine for a trip south on a Korean #icebreaker to deploy some instruments into a #polynya. But a few weeks back got bumped as voyage plans have all changed due to crazy #SeaIce 😞 on the other hand I get to be warm for Xmas which is not always the case. (pic Brett Grant/NIWA)

From the operational oceanography side, we get quite frequent images of the #polynya from a variety of satellite missions (radars, optical, passive microwave,...) We have some in-situ obs of the water column.

I do not think we have skillful short-range forecasts of the opening of the #polynya (or I do not know about them).
