Abstract

The multidisciplinary teaching cruise AL580 was part of the curriculum of the master
“Biological Oceanography” at the Christian-Albrechts-University Kiel and the GEOMAR
Helmholtz Centre for Ocean Research. During this mandatory part of the MNF-bioc-301 module
the students were able to gain hands-on experience of the scientific operation on-board a modern
multidisciplinary research vessel. Methods in physical, biological and chemical oceanography
were taught based on biodiversity changes in several functional plankton groups along the Baltic
Sea salinity gradient as a main subject. The students performed tasks such as deploying state-of-
the-art measuring and sampling gear, data and sample collection as well as first on-board
analyses and curation of data and samples for later use. The on-board analyses included
taxonomic identification, measurements and counts of plankton organisms, determination of
dissolved oxygen and chlorophyll A concentrations and recording of CTD profiles. Further
samples were collected for later analyses during other practical courses in the master curriculum
such as seawater samples for eDNA and viral plankton analyses. The work with the crew
onboard ALKOR was outstanding.
