Gaussberg (PS141 - Davis Sea/Antarctica)
Gaussberg is an extinct volcano on the coast of the Southern Ocean (Davis Sea) in Kaiser Wilhelm II Land in Antarctica.
The height of the volcanic cone, which corresponds to a nunatak, is 371 meters above sea level and its prominent peak rising out of the ice field is the only ice-free place in the area.
During expedition PS141 of the R/V Polarstern, a team from TU Dresden, supported by colleagues from the University of Tasmania, will set up a field camp on Gaussberg for 3-4 weeks and in particular carry out geodetic measurements in order to measure movements of the Earth's crust as a result of past and present ice mass changes.
Barn Bluff Cradle Mountains / Tasmania
Barn Bluff is a mountain in the west of the Australian state of Tasmania. It is located in the northern part of the Cradle Mountain Lake St Clair National Park south of Cradle Mountain and forms the boundary between the catchment areas of the Murchison River and the Mackintosh River.
At 1,559 m high, it is the fourth highest mountain on the island, 14 m higher than the much better known Cradle Mountain.
It is often covered in snow, sometimes even in summer. The solitary mountain can be seen from most parts of the national park and is therefore one of its most important sights. It is a popular destination for mountaineers and hikers.

The mountain consists of diabase columns, similar to other mountains in this region.

Bernhard the Cattle Egret (PS139 - Tropical Atlantic)
Shortly after passing the Canary Islands, we had a visitor: A white, medium-sized bird - initially identified by some as a swan - landed on the deck. A little shy, but also curious, it stalked around and inspected the ship that was to be its home for the next two weeks. After a few days, we all agreed that it was a cattle egret - Bernhard - who had probably lost his way on his journey. Within a very short time he had made many friends on board, became very trusting and from then on there was no more activity without him!
The CTD rosette (conductivity, temperature, depth) is a probe for deep-sea investigations. It is usually lowered by oceanographers from research vessels on a long cable to a depth of several thousand meters. (PS139 - Tropical Atlantic)
