A Mixing Rate Approach to Understand Nutrient Distributions in the Plume of Mississippi River
Studies of estuarine chemical and biological distributions frequently focus on biogeochemical processes while ignoring how the rates of these processes might compare with mixing rates. This is understandable in view of the complex physical regime of many estuaries. In this report a mixing rate diagram is described which shows freshwater transit times versus salinity. This approach is straightforward to construct and can provide information regarding relative rates of mixing (or dilution) in different parts of an estuarine/coastal mixing zone. A simplified preliminary application of this approach suggests that nutrient uptake in the plume of the Mississippi River may be related to a slowing of the mixing process at high salinities.
