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

Secondly, […]
