PhD project title:

Seasonality and activity of Arctic zooplankton.

PhD project description:

My PhD will consist in identifying seasonal and diel zooplankton behaviour in Arctic and sub-Arctic waters. The first chapter of my PhD will be about the seasonal light response of Calanus finmarchicus in a high latitude fjord. This response is studied by recording individual behaviour of C. finmarchicus in the laboratory under natural light cycle every month. In parallel, I use acoustic methods to determine the migration behaviour of zooplankton.  The second chapter is a long time series of acoustic data from Rijpfjord, Svalbard.  The aim is to know how zooplankton’s vertical migration change seasonally and through the year in a known environment. To be able to predict those behaviour under climate change.  The third chapter as for purpose to use acoustic data from autonomous drifting observatories, to have a pan arctic image of zooplankton behaviour.

Start date: Nov 2018
