31 March 2020 It took us much longer than we had expected, but last Monday (23 March) Gina and I did our first DataHawk drone flights of the MOSAiC expedition. These were also the first scientific drone flights of MOSAiC. The data that we collect as we fly our DataHawks will allow us to study how the atmosphere… Read More

19 March 2020 After more than 20 years of doing polar fieldwork one thing I have learned is that delays are an inevitable part of any field campaign. That seems to be truer than ever with my MOSAiC work so far. First, our transit from Norway to the Polarstern, on the Russian icebreaker Dranitsyn, took… Read More

10 March 2020 It’s been a week since I moved onto the Polarstern and it has been a busy week. The Dranitsyn arrived at the MOSAiC ice floe on February 28th and the next 4 days were occupied with the transfer between the leg 2 scientists that had been on the Polarstern since December, and… Read More

1 March 2020 On February 28th the Dranitsyn reached the Polarstern and the MOSAiC ice floe. Everyone onboard was very excited to have finally reached our destination after almost 4.5 weeks since leaving Tromsø.  Starting on the 27th we were able to see the lights of the Polarstern in the distance. The bridge of the… Read More

26 February 2020 This past Monday marked the end of my 4th week on the Kapitan Dranitsyn. Our progress towards the Polarstern has been very slow due to thick ice, but we are now within 30 miles of the Polarstern and I hope to be onboard that ship in another few days. Everyone on the… Read More

17 February 2020 In my previous blog posts I’ve talked about my trip so far but haven’t given any details about the research that Gina and I will do once we reach the Polarstern. Before I discuss that I do want to give an update on our progress towards the Polarstern.  We’re still in transit… Read More

A week after boarding the Kapitan Dranitsyn and 5 days after we left port in Tromsø for a sheltered anchorage in a fjord we finally started sailing north towards the Polarstern. As I mentioned in my previous post we spent several days in the fjord waiting for a storm to pass to our north. When… Read More

I’ve been on board the Russian icebreaker, the Kapitan Dranitsyn, for the last 3 days and in this blog post, I’d like to give you a sense of life on board the ship. We boarded the Dranitsyn on Monday evening (January 27th) but, as I’ll explain later, we haven’t made much progress towards the Polarstern… Read More

I am currently in Tromsø, Norway getting ready to sail into the ice pack of the Arctic Ocean on the Russian icebreaker the Kapitan Dranitsyn. I left my home in Colorado on Wednesday 22 January, on an unseasonably warm winter day, and landed in Tromsø on the evening of the 23rd, in a snow shower.… Read More

17 January 2020 My name is John Cassano and I am a professor at the University of Colorado. My research focuses on polar weather and climate, and as those of you that have read my blog in the past know, I have made many trips to Antarctica (scroll down to see these earlier blog posts). … Read More
