Small-Scale Biophysical Interactions.

Abstract

The long-term goal of this project was to better understand and quantify the coupling between physical and biological processes on a variety of temporal and spatial scales. We were especially interested in the role of mixing as it influences the rates of biological processes. Our specific objectives were to: quantify the relationship between the microscale physical structure of the water column and the microscale distribution of phytoplankton biomass; quantify the time scales of bio-physical correlations over the microscale, especially in relation to the time scales predicted from first principles; evaluate the correlation between temperature and/or density steps (gradients) and the observed small-scale biological structure. We have a large data set of microstructure profiles obtained with a laser/fiber optic profiling system. The concurrent measurements of physical and biological variables over small scales (O.O2m) has allowed us to determine the temporal and spatial scales of correlation between these variables. We have approached the project objectives through extensive data analysis of these profiles.
