Suspended particle dynamics and fluxes in an Arctic fjord (Kongsfjorden, Svalbard)
International audience An experiment was carried out during summer 2015 in the inner part of the Kongsfjorden to study the inputs of meltwater and behaviour of associated suspended particles. We used a wide range of oceanographic instruments to assess the hydrological and hydrodynamic characteristic...
