Dynamics of island mass effect – Part II: Phytoplankton physiological responses Open
Island mass effect (IME) refers to the phenomenon of elevated chlorophyll a ([Chla]) concentrations around islands, often extending hundreds of kilometers into oligotrophic waters. In this study, we explore the physiological responses and …

Ubiquity of inverted ’gelatinous’ ecosystem pyramids in the global ocean Open
Summary paragraph Plankton are essential in marine ecosystems. However, our knowledge of overall community structure is sparse due to inconsistent sampling across their very large organismal size range. Here we use diverse imaging methods …

Predicting global distributions of eukaryotic plankton communities from satellite data Open
Satellite remote sensing is a powerful tool to monitor the global dynamics of marine plankton. Previous research has focused on developing models to predict the size or taxonomic groups of phytoplankton. Here, we present an approach to ide…

Ocean-wide comparisons of mesopelagic planktonic community structures Open
For decades, marine plankton have been investigated for their capacity to modulate biogeochemical cycles and provide fishery resources. Between the sunlit (epipelagic) layer and the deep dark waters, lies a vast and heterogeneous part of t…

Complete zooplankton size spectra re-constructed from « in situ » imaging and Multinet data in the global ocean Open
Plankton size spectra are important indicators of the ecosystem state, as they illustrate the quantity of organisms available for higher marine food web and reflect multiple size-dependent processes. Yet, such measurements are typically bi…
