The First International Symposium on the Biogeochemistry of Model Estuaries was held May 21–27 in Primosten, Yugoslavia. The goals of the symposium were to bring together scientists from North America and Europe to present results of studies on biogeochemical processes in estuaries, discuss strategies for developing a more fundamental understanding of these processes, and pursue ways to achieve better international cooperation. About fifty scientists attended.
A major focus of the symposium was the results from a French-Yugoslavian cooperative study of the biogeochemistry of the Krka estuary in Yugoslavia. The Krka is a stratified estuary that drains a karsted carbonate watershed. The system provides a model for studying biogeochemical processes in estuaries that receive low suspended solids but relatively high dissolved solids in terrestrial runoff. The project was also an opportunity to examine interfacial processes at the well-defined density boundary. Results demonstrated the importance of that boundary in controlling the biogeochemistry of the system.
