Weekly Reports Polarstern

The Expedition PS98 from Punta Arenas to Bremerhaven

In the framework of the OCEANET programme, detailed observations of the atmosphere will be carried out, targeting aerosols and clouds and their effect on atmospheric radiation and atmosphere-ocean exchange. As a further aspect (like already on ANT-XXIX/10), the route will be chosen to obtain optimal matchups with satellites from the A-Train constellation, specifically the CALIOP aerosol lidar and the CLOUDSAT cloud radar. The resulting datasets will offer the unique opportunity to compare vertically resolved profiles of clouds and aerosols from the satellite and ground-based perspective.

Furthermore, Antarctic king crabs will be transported to Bremerhaven for further studies. In addition, preparations for the development of a web-based drift monitoring system will be done.

Between Las Palmas and Bremerhaven a training course for Echosound instruments will be held, with 20 students and 5 lecturers.

Training in Sediment Acoustics

[09. May 2016] 

On Tuesday, May 3rd, a group of 20 Masters and PhD students and 5 instructors boarded the R/V Polarstern in Las Palmas. Some of those who have already been on board from Punta Arenas for more than three weeks, took the occasion to make a short shore leave.

Crossing the equator

[03. May 2016] 

On Tuesday last week, the route of Polarstern towards its home base crossed the equator. Shortly after that we also traversed the “atmospheric equator”, the so-called Intertropical Convergence Zone (ITCZ), which is usually associated with heavy rain showers and thunderstorms.

Through the humid southern trade winds

[26. April 2016] 

We are now in the second week of our cruise back to Bremerhaven and have already nearly reached the equator. For the last few days, we have experienced tropical weather conditions with temperatures around 28°C and high humidity.

Beginning the return voyage

[19. April 2016] 

The last cruise section of this year’s Antarctic season for Polarstern started on 10 April 2016 in Punta Arenas and will end on 12 May in Bremerhaven. Until Las Palmas, we have 14 scientists on board who are mainly studying the atmosphere above the ship. Another group takes care of the transport of king crabs. In Las Palmas 25 additional people will board our vessel for an echosound training course.

PS97 Weekly Report No. 7 | 30 March - 6 April 2016

Towards the Strait of Magellan

[07. April 2016] 

For both crew and scientists the last week of our Polarstern expedition PS97 required everyone to dig deep. A varied geological, geophysical and oceanographic work program was accompanied, or shall we say interrupted, by two major storms.
