MOSAiC Expedition



PS121 - Weekly report No. 4 | 01.09. – 08.09.2019

Last activities

[09. September 2019] 

This is the last weekly report for PS121, which describes our activities on board during a full week of research. The research activities have continued to go well, and there is already a feeling on board that the expedition is nearing the end.

Long-term observations

[04. September 2019] 

In the last weekly report, we reported that a long-term observatory such as the HAUSGARTEN is defined by the implementation of regular, standardized investigations at set stations. Because of this, the course of an expedition such as PS121, for which the work is mostly dedicated to furthering the long-term observatory HAUSGARTEN, can be sketched out pretty well before the expedition.

Working in Hausgarten

[04. September 2019] 

A large part of the work and projects that we scientists planned for this expedition are closely related to furthering the long-term observatory HAUSGARTEN, established by the AWI’s Deep-Sea Group 20 years ago, and to supporting the Helmholtz Infrastructure Initiative FRAM (Frontiers in Arctic Marine Monitoring). The long-term observatory Hausgarten is a network of twenty stations in the Fram Strait, whose coordinates are re-visited by us every year in the summer months.

Stormy start

[02. September 2019] 

About a week ago, in the evening hours of August 10 in Bremerhaven, it was “lines off” for Polarstern, as she set course through the initially calm sea towards the long-term observatory area Hausgarten. Every single spot on the ship is full with us, 53 scientists, engineers, technicians, and students from various national and international research institutions.

The Scent of the Ocean

[01. July 2019] 

Over the past few days, one could smell a scent of ocean, again. It is also interesting that as one get closer to the European shelf on board a ship, one notices that the water is no longer has the hue of the deep ocean blue or the shimmering turquoise of tropical waters. The waters are less clear and they have the same gleam as dark green glass.
