Environment and climate: The Expedition Blog

Rieke Schäfer, who is 26 years young, is a doctoral student at PTB and at the GEOMAR Helmholtz Centre for Ocean Research Kiel. For two months (from April to June, 2023), she was swapping her laboratory workstation at PTB for the German research vessel Sonne (which is the German for “sun”), where she was soon finding her sea legs. The sun was wasn't in short supply. And she was having a shipload of experiences that she’ll never forget. This voyage took her thousands of kilometers along the equator from Ecuador, with the final port of call being in Australia. Anyone who wanted to follow her journey could do so by following this blog - and still can do. You could (and can) also find out about her expedition on our LinkedIn channel.
