An-AUV Based Investigation of the Role of Nutrient Variability in the Predictive Modeling of Physical Processes in the Littoral Ocean
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 physical/biogeochemical 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.
