Ice Investigation #1: If icebergs melt, will sea level rise?
Materials (per pair or team): deep dish pie or cake pan, toothpick, modelling clay, 2-3 ice cubes, water, clear plastic wrap
1. Give each team of students a pan and a lump of clay.
2. Mould the shape of a continent, pressing the edges flat against the pan.
3. Pour in water to partially cover the clay continent.
4. Put several ice cubes in the water to represent icebergs. (Note: The more ice you use, the easier it will be to see any changes in water level.)
5. Trace the water level into the clay with a toothpick or pencil.
6. Cover the pan with clear plastic wrap to prevent evaporation of t...

Acidification of the oceans - what's the impact on fish?
Climate change-induced increase of carbon dioxide, according to modelling approaches, is going to cause the acidification of the world’s oceans. By the year 2100 the current pH might drop by 0.5. Our research is focusing on the question ‘how do fish respond to such changes?’
At the department "Marine Animal Physiology" of the Alfred Wegener Institute, researchers developed a device that enables onboard measurements of the impact of decreased pH values on the gill functioning of freshly caught fish (see overview photograph). In order to simulate blood circulation, specially prepared gill tissue is constantly flushed with a saline solution. Special devices allow measurements to be taken of gill performance in plain and acidified seawater for more than 6 hours (see det...

Art meets science – octopus and biologist create art onboard “Polarstern”
Education and Outreach is playing an ever increasing role in the world of science. This is also true for our expedition especially with regard to the upcoming International Polar Year. Scientists, which rely on funding from the government, fulfil their obligation towards the general public and funding bodies by communicating their results in an easy and comprehensible manner. More and more scientific organisations such as the "Census of Marine Life" encourage liaisons between art and science. Unfortunately due to great scientific interest it was not possible to give an artist the opportunity to join the expedition. But an unexpected awakening of creativity, imagination, and artistic talent occurred onboard the “Polarstern”. Indeed these are skills that are also of high relevance to a...

Paradigm shift in octopus habitat use – what do they do without rocks and crevices
“The Octopods are for the most part benthic or bentho-pelagic, living in holes or crevices, beneath large rocks or in caves… ” This has been the dogma of octopus habitat use for decades because observations have been limited to areas of the oceans where octopuses could be easily found: shallow, near-shore and typically rocky, habitats. But what of the majority of the ocean floor, where the bottom is characterized by muddy and sandy sediments, is there a place for octopuses here? The answer is "yes". Today’s technology enables us to see the ocean floor almost everywhere with high-resolution still photography and ROV-mounted video cameras. Images from the Polarstern’s first deployment of the photosled show octopuses burrowed in fine sediment, as seen in the attached image. Waters...

Stellar Axis Midsummer Performance
On December 22nd 2006, after completing the Stellar Axis star map on the Ross Ice Shelf in Antarctica, artist Lita Albuquerque conducted a performance using an Archimedian Spiral and 51 volunteers from the nearby US McMurdo station. Starting at the center, the participants walked out along the spiral arms to the boundary of the installation taking 10 minutes to complete the journey. The star map around which they spiraled mirrored the sky above on the Southern Hemisphere's Summer Solstice. The event was filmed from a helicopter and from the ground. Photographs were taken by Jean de Pomereu of the International Polar Foundation.

Likely new parasite found in stomachs of Emperor penguin chicks
Penguins are the uncontested cutest birds worldwide. In the great colonies of the Emperor penguins (Aptenodytes forsteri) in the high Antarctic it happens often that young chicks die a natural death. This provided a unique opportunity for us (Sven Klimpel and Markus W. Busch) to analyse the parasitic fauna and stomach contents of these fascinating birds. Such investigations are important because they provide information on the life of the parasites and also on the habitats and general trophic status of the penguin hosts within the Antarctic ecosystem.
The Emperor penguin colony close to the German Neumayer Station is one of approximately 35 known colonies in Antarctica. We collected 12 dead chicks for parasitological and feeding ecology examinations on board. It was found th...
