A COASTAL-related PhD Defense at Stockholm University (Friday, 3 December 2021)

A COASTAL-related PhD Defense at Stockholm University (Friday, 3 December 2021)

There is a COASTAL-related (and COASTAL-acknowledging) PhD defense by Guillaume Vigouroux at Stockholm University, who has worked specifically on the eutrophication and water quality issues in the Baltic Sea and its coastal areas.


Title: Managing coastal eutrophication: Land-sea and hydroclimatic linkages with focus on the Baltic coastal system

When: Friday, 3 December, 13:00 - 15:00 (Swedish time)

Where: Online via Zoom, public link:


Eutrophication endangers coastal ecosystems all over the world and is most often associated with an increase in anthropogenic nutrient loads to coastal waters, which fuel the growth of algae and create a variety of environmental problems. This is also the  case for the Baltic Sea where coastal waters may be affected by various land, coast-sea, and hydroclimatic drivers and feedbacks, over different scales, including the eutrophic open sea. This thesis aims at improving the understanding of how these drivers affect coastal eutrophication and its management opportunities across the various coupled scales of the Baltic land-coast-sea system. To achieve this aim, the interactions between land-catchment, coastal, and open sea processes, and their influences on coastal eutrophication have been investigated through water quality modelling with applications to specific Baltic coastal  waters. Hydroclimatic influences on the propagation of change-impacts through the land-coast-sea continuum to coastal eutrophication have also been investigated via the water quality modelling and additional analysis of actual water quality trends over the last 30 years along the Swedish coast. Moreover, coastal eutrophication research on the Baltic Sea system has been investigated through scientific literature analysis with focus on how the reported research has accounted for and linked components in the land-coast-sea system, and the aim to identify possible research gaps.
