Welcome to the Aquatic Eddy Covariance Research Lab at the University of Virginia. We work with the eddy covariance technique, also known as the eddy correlation technique, for underwater flux measurements in three main areas:
The eddy covariance technique was developed by Peter Berg and the Max Planck Institute for Marine Microbiology, Germany. The first proof of concept paper focusing on oxygen fluxes for different benthic environments was published in 2003 (Berg et al. 2003), and since then an increasing number of groups have adopted the approach.
The technique is more expensive and challenging to apply than traditional benthic flux methods, but it has several unique advantages:
For most benthic ecosystems, the eddy covariance technique represents the closest we come today to measuring true in situ fluxes.
The technique has been used in the atmospheric boundary layer for many decades, and it is by far the most common approach for measuring fluxes between land and air. We hope to see a similar development for the aquatic environment as more experience is gained with the technique and more sensors are being developed.
This research is made possible by funding and support from the University of Virginia and the National Science Foundation.
