Abstract:

Our long-term goal is to assess the effectiveness of nutrients as tracers of geophysical fields in the oligotrophic littoral ocean, utilizing various sampling and measurement protocols in a feedback approach with a prognostic physicalbiogeochemical model. Ultimately, relevant nutrient gradients are to be measured by a nutrient sensor aboard an AUV. Our more immediate and specific objectives fell into two groups 1 those associated with the decision about and the initial development of a prognostic model suitable for coastal waters on the West Florida Shelf and 2 those associated with the high-sensitivity nutrient methods used to map nutrient distributions and gradients on the West Florida Shelf in support of the modeling effort. Group 2 objectives included improvement of our analytical methods for nitrate, nitrite, and ammonia investigation of a high-sensitivity phosphate method and preliminary field studies of spatial scales of the nutrient distributions that would eventually be the subjects of both nowcasting and predictive modeling.
