Plankton blooms in vortices: The role of biological and hydrodynamic time scales [PDF]
Nonlinear Processes in Geophysics 14, 443-454 (2007), 2008 We study the interplay of hydrodynamic mesoscale structures and the growth of plankton in the wake of an island, and its interaction with a coastal upwelling. Our focus is on a mechanism for the emergence of localized plankton blooms in vortices. Using a coupled system of a kinematic flow mimicking the mesoscale structures behind the island and a ...

Biological activity in the wake of an island close to a coastal upwelling [PDF]
Ecological Complexity 5, 228-237 (2008), 2008 Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region. Our research is based on numerical analysis of a kinematic flow mimicking the hydrodynamics in the wake, coupled to ...

Deep Learning Classification of Lake Zooplankton [PDF]
Frontiers in Microbiology, 2021 Plankton are effective indicators of environmental change and ecosystem health in freshwater habitats, but collection of plankton data using manual microscopic methods is extremely labor-intensive and expensive.

Findings of new phytoplankton species in the Barents Sea as a consequence of global climate changes [PDF]
PeerJ, 2023 Over the past few decades, the Earth’s climate has been characterized by a stable increase in temperature, which in many regions leads to a change in the composition of flora and fauna.

Feeding ecology of Benthosema glaciale across the North Atlantic
Frontiers in Marine Science, 2023 The glacier lanternfish Benthosema glaciale is a key myctophid with a wide distribution in the northern Atlantic. It is a species that has a strong vertical migration capacity and have the potential to move between the surface waters and mesopelagic ...

Predator-prey plankton dynamics in turbulent wakes behind islands [PDF]
Phys. Rev. Fluids 6, 103802 (2021), 2021 Plankton constitutes the productive base of aquatic ecosystems and plays an essential role in the global carbon cycle. The impact of hydrodynamic conditions on the biological activity of plankton species can manifest in a variety of different ways and the understanding of the basic effects due to multiscale complex flows still appears incomplete.
