Objectif The objective of this research is to extend the knowledge of the processes affecting transformations and fates of particles and biogeochemically important elements and to compare their propagation in Arctic estuaries and temperate estuaries. This study will assess the importance of Arctic estuaries in global geochemical cycling.A preliminary site survey of a number of Arctic estuaries in the Kandalaksha Bay, White Sea, Russia, was carried out in order to identify suitable study sites and to address potential logistical problems. As a result of this survey three estuaries have been identified as being scientifically and logistically suitable.The objective will be achieved by characterising the physical, chemical and ecological interactive processes within each estuary and its immediate coastal zone and the quantification of fluxes at the significant boundaries, e.g. river/estuary, sediment/water interfaces. Intensive seasonal investigations (spring, summer and autumn seasons) will provide essential data on diurnal, tidal and seasonal time scales. During these surveys the most significant physical, chemical and biological variables will be measured, including the vertical and horizontal structure of salinity, temperature, dissolved oxygen, pH, turbidity, nutrients, trace metals and primary production, zooplankton and phytoplankton abundance and speciation. Results will be used to create integrable ecosystem models of the key processes. Papers arising from the research will be published in international journals.
