Matthew Shupe's Blogs from Polarstern

Matthew Shupe, CIRES and NOAA - An entire year frozen into the Arctic Ocean. 600 people from 17 countries. The largest Arctic climate expedition ever… In September 2019 the German research icebreaker Polarstern departed from Tromsø, Norway and parked next to a chunk of sea ice. CIRES scientist Matthew Shupe writes near-daily blogs.

Like Astronauts...

David Costa, CIRES & NOAA - It's really cool to see everyone on the ice with their headlights in the dark. We're like astronauts on the moon. We all wear the same snow suit, and you can only see people's eyes. I usually wear goggles, too: At -26C, exposed skin doesn't last long.

Weekly Update from Byron

Byron Blomquist/CIRES and NOAA - For the past week or more we have been drifting to the NW, more or less in the direction we need to go, at a speed of 0.1 to 0.3 kts. We are currently at 85° 35.3' N, 126° 9.03' E. Following the current drift course we would pass to the W of the N pole, but random shifts in direction may get us there yet.

Weekly Update from Byron

Byron Blomquist, CIRES and NOAA - This Thursday will be the 'official' start of routine sampling and observations for MOSAiC which will continue for the next year. In reality, some instruments have been operating for several days already and preliminary snow and ice sampling surveys have occurred over the past two weeks.

Goodbye and Good Luck, Polarstern!

Janek Uin, Brookhaven National Laboratory - It’s our last day on R/V Polarstern with the feeling of mission accomplished. We are transferring to the other icebreaker today, and this will be my last update until I get back to Norway.

Remote Sensing and Buoy Simulations: Important Tools for MOSAiC

Ryleigh Moore, University of Utah - My name is Ryleigh Moore and I am an applied mathematics PhD student at the University of Utah. I currently study the evolution of Arctic melt pond geometry for one of my research projects and I am also working on numerical solvers for high dimensional stochastic differential equations.

Weekly Update from Byron

Byron Blomquist, CIRES & NOAA - Today was Day 24 of the cruise and the 10th day of the drift. The setup phase is drawing to a close and our colleagues who came for the install will leave on Federov this Thursday. With that, the measurement phase begins. For our project, the ship bow tower was raised on Saturday and the sonic anemometers and Licor are running.

How to Predict the Weather on a Russian Icebreaker

Mauro Hermann (ETH Zürich, Institute for Atmospheric and Climate Science), Thea Schneider (YOPP / University Potsdam), and lecturer Thomas Rackow (YOPP / Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research - Predicting the weather is not an easy thing to do - we know that from everyday life. No rain predicted? Maybe take a jacket with you anyway, because the weather is a chaotic system. This means that even small initial perturbations can lead to a very different outcome. In weather prediction, numerical computer models are used.

Weekly Update from Byron

Byron Blomquist/CIRES and NOAA - Today is day 3 of the official MOSAiC drift. Over the past week a location for the Central Observatory was finalized and we spent a couple days transferring cargo and personnel from Federov. During the rendezvous with Federov a mother polar bear and yearling cub spent quite a bit of time investigating the ships.

Ice Watch on the Akademik Federov

Daniel Watkins/Oregon State University - Once every hour, a pair of volunteer ice observers climbs up to the 8th floor of the ship and goes out on the observation deck to watch the ice. For 10 minutes, they watch sea ice pass by the ship. They note how much ice there is, and if there is any water visible, whether it is only in cracks, in patches, or in wide channels called leads.

Breaking Bad (Ice)

Jessie Creamean, Colorado State University - Ah, the beautiful, brilliant aqua blue of pristine crystals. And no, I am not referring to the color of something a certain chemist makes from a certain hit TV series based in Albuquerque … I am referring to one of the most vibrant blues I have ever set eyes on, originating from multiyear sea ice in the vast waters of the Arctic Ocean.

Watching Ice Grow

Katy Gavenus, PolarTrec - Each hour, two of us go up to the deck above the bridge and spend 10 minutes watching the sea ice within about 1 nautical mile of the ship. Then we record our observations. We do this during the day and also during the night. There are lots of volunteers on the ship, so we rotate through...

Progress Update from Byron

Byron Blomquist, CIRES/NOAA - We are now on day 10 of the cruise. We spent it parked near a likely ice floe of about 2x3 km size and are considering it as a site for the central observatory. Surveys will continue tomorrow. Most of the other sea ice we've encountered in the area is thin (~30 cm) and soft, soaked with seawater, and thus not very promising for an ice camp.

Ice and a Polar Bear

Anne Gold, CIRES - We finally hit sea ice and it is AMAZING. The glow is so strong that it felt like the sun was rising at 3 am. Our ship slowed down to 10 knots. We are switching time zones again! The ice is all broken up and beautiful. I have taken so many pictures...

Progress Update from Byron

Byron Blomquist, CIRES/NOAA - By the closest of margins, we managed to get all of our equipment and supplies loaded on a ship. Federov delayed departure by about 1/2 a day ... to collect our compressed gas standards, which arrived very late. That was a close call and I'm thankful to Markus Rex for organizing a delay to be sure the standards were loaded.
