Polarstern: A Triceratops in the ice
Written Friday, 21 December
What is a Triceratops doing in the ice? It is the logo on one of the containers aboard Polarstern, coming along with seven scientists from the Senckenberg Institute on an expedition!
The equipment which the Senckenbergians brought with them on board the Polarstern did indeed fill a whole container: lab equipment, chemicals and sample jars were purchased by Annika Henche and packed into aluminum boxes together with microscopes. The large equipment of the DZMB – epibenthic sledge and multicorer – were tested and made ready for action. The container was shipped from Wilhelmshave...

Polarstern: In the pack ice
Written Thursday, 20 December
2.3 knots... 2.0..1.9...1.2... 0.0. A glance at the screen in the red saloon during tea reveals it quite unambiguously: we are still stuck in the thick pack ice near Neumayer Station. The courageous Polarstern moves forward and backward and forward again, listing slowly to one side, shaking as if under a heavy burden — again a few meters gained.
It is a lovely day, the ice gleaming white under a pastel blue sky, like lightly dropped dollops of meringue — but the nice picture is deceptive. The imposing pieces that Polarstern forces out of the closed ice cover hardly move, a...

Polarstern: To be David Attenborough for a day
Written Wednesday, 19 December
Hi, it’s me again, Nils. Here on Board of Polarstern I am responsible for the deep-sea camera, and when I am not busy taking pictures of the ocean floor, I film what is happening around me. And of course the most impressing thing one can film here on the ice is wild penguins. The small, funny Adelies and the nearly 1 m tall, very dignified Emperor penguins are en route to their brooding places.
Of course I have to film th...

Polarstern: The Rauschert Dredge
Written Tuesday, 18 December
Most of the scientists on board are specialized in the study of marine life and every opportunity to see or sample what lives on the bottom of this ocean is taken very seriously in consideration. Luckily enough during the delicate task of providing fuel to the station, a few hours had to be spent in the vicinity of the ice shelf; this time was indeed needed for the people from Neumayer to reach our position. This was the perfect opportunity to use one of our sampling gear called “the Rauschert Dredge” (named after Dr. Martin Rauschert who designed this device) and see what creatures we could catch on the sea floor, 500 meters below the icy surface of the water.

Polarstern: Forecasting the weather
Written Monday, 17 December
The well-known saying “weather happens all the time and everywhere” is valid also on board Polarstern. While the scientists had a break during the last few days which were devoted to the supply of Neumayer station, it was business as usual for me as the shipboard meteorologist.
The weather station on board is always running normally, regardless whether the task is transit, science work on station or supply. Our responsibilities include weather observations and radio sonde surveys (with weather balloons) as well as forecast and advice. Especially in a region like the Antarcti...

Polarstern: Offloading equipment for Neumayer
Written Sunday, 16 December
With full power Polarstern rammed herself into the relatively homogeneous sea ice of Atka Bay and then delivered equipment for the Neumayer station onto the ice. Sleigh trains pulled by piston bullies carried the freight containers over 10 km of sea ice to the shelf ice edge. Only fuel can not be delivered this way. The full tank containers on sleds would be too heavy and could be lost.
All participants on board had an opportunity to visit the station via helicopter shuttle flights. I stayed on board, let my colleagues deliver packages and instead took care of the “old overwint...

Polarstern: Neumayer, Antarctica
Saturday, 15 December
“Overwhelming!” — yes, that is the best way do describe it. Today was by far the most overwhelming day of our journey, as we went to Neumayer station. I knew that the first helicopter shuttle flights were scheduled for 9 o’clock and that probably everybody wanted to take off at the same time. There are only 4 seats on a helicopter, so I planned to fly around 11 o’clock, thinking that the first rush would be over and surely nobody wanted to go right before lunch, right? However, by 10 o’clock there was nothing that could have held me on the ship, I just wanted to go. During breakfast I had read the brochures on “Neumayer” and the “Library in the Ice”, then filled my water bottle, made a sandwich for lunch, put sun screen on, inserted ...

Polarstern: Snow, ice and penguins
Written Friday, 14 December
What an unreal day. In the morning probably nobody would have thought that the day might have such a spectacular end. Since yesterday we were just going back and forth in the same spot and not going anywhere all day long. It was not clear at all when we would reach the shelf ice edge to supply Neumayer station with vegetables, fruit and other things.
Until 2 o’clock in the afternoon I was minding my own business, working away, and then looking out the window just by chance: lots of white, but there were a few little black dots. Penguins? Yes! Not just one but lots of them!!! In...

Polarstern: Preparing for disembarkment
Written Thursday, 13 December
Today is the fifth day since we have started to fight our way through the sea ice. Last night our average speed was about 6.2 knots, and slowly but surely we are approaching Neumayer station. The happy expectation among us is tangible, as the hour comes near with our arrival in which we may leave the ship and have a go at the ice. Fifty-three biologists, oceanographers, geologists, chemists and meteorologists are being let loose in the pristine world of ice. And the thicker the ice becomes and the more powerful the ramming of the ship against it, the heavier the intermittent snowfall, und the more frequent the sightings of crabeater seals (a seal species living here) and Emperor penguins, the more the right index finger is tingling above the shu...

Polarstern: Animal census
Written Wednesday, 12 December
My goodness, I have not seen this much ice in my whole life. The diffuse light blurrs the horizon, and without sunglasses I would indeed go blind.
While Polarstern is working her way through the ice toward Neumayer Station, the Dutch scientists are flying daily transects off the ship to survey the ice. Besides the pilot, two members of the Dutch team are sitting in the helicopter, and each day they are taking along a guest investigator to count and survey animals. I was lucky to be the first to fly because by chance my name ended up on top of the list of helicopter guests. ...
