| contents | High throughput imaging reveals widely occurring diel vertical migration among phytoplankton. Garefelt, Karin Karlson, Bengt Brosnahan, Michael L Kraft, Kaisa Torstensson, Anders Seppälä, Jukka Cembella, Allan Andersson, Anders F Phytoplankton undertake daily vertical migration through the water column to optimize light and nutrient access while avoiding predators. However, diel vertical migration (DVM) patterns remain poorly characterized for many taxa due to limitations of labor-intensive traditional microscopy. Here, we employed high-throughput imaging flow cytometry to investigate DVM. An Imaging FlowCytobot (IFCB) was deployed to continuously profile the vertical water column for ~10 weeks (August-October 2016) at a location in the Skagerrak, eastern North Sea. This revealed significant DVM for several morpho-taxonomic groups, including taxa belonging to ciliates, dinoflagellates, and diatoms, shifting median depth by 2-6 m between night and day. The analysis also revealed that DVM can be inferred from diel pulses in surface water biomass, which we leveraged to study DVM in an extensive IFCB time-series dataset from the central Baltic Sea (June-October in 2020 and 2021). Migratory taxa accounted for 77% and 79% of total phytoplankton biomass (size range |
