Abstract:

Our long-term goal is to quantify the interactions between small-scale biological and physical processes in the upper ocean. This project addresses that goal by examining the coherence in the distribution and variability of small-scale bio-optical properties with coincident spatial and temporal scales of physical properties and processes. Our scientific objective is to resolve temporal and spatial patterns in bio-optical and physical processes on those scales most relevant to planktonic organisms. Given the small size of planktonic organisms and the range of time intervals over which these organisms grow and reproduce, our objective requires observations that span centimeters to tens of meters in the vertical dimension, over time intervals of minutes to days. Integration of physical measurements with the biological measurements, on the same time and space scales, provides the opportunity to evaluate the trophic consequences of particular patterns of distribution and variability. Only by virtue of technical advances within the past few years, however, are we able to obtain the necessary high-resolution observations to address these questions.
