Full Description
This is the first book for over twenty years on the physical, biological, chemical and geological characteristics of a large-scale estuary. Interdisciplinary, concise and cohesive, it is applicable as a model for worldwide estuary study. From the contents: Mathematical Modeling of Tides in the St. Lawrence Estuary.- Fronts and Mesoscale Features in the St. Lawrence Estuary.- Nearshore Sediment Dynamics in the St. Lawrence Estuary.- Organic Geochemical Studies in the St. Lawrence Estuary.
