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

Abstract

Our principal 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 package aboard an AUV, and so this capability is also a long-term goal. The nutrients to be studied are dissolved nitrate, nitrite, and ammonia because these have the greatest prospect of exhibiting variations that might be useful as tracers.
