June 2020

New proof-of-concept paper on air-water gas exchange measurements in lakes and reservoirs by upside-down underwater eddy covariance from a moving platform. The approach enables us to measure gas exchange under true in situ conditions with unprecedented high temporal and spatial resolution:

Berg, P., M. L. Pace, C. Buelo (2020). Air-water gas exchange in lakes and reservoirs measured from a moving platform by underwater eddy covariance. Limnology and Oceanography: Methods.

May 2020

New paper on inter-tidal oyster reef metabolism. Aquatic Eddy Covariance measurements is a valuable approach to monitor oyster reef health and restoration effort:

Volaric, M., P. Berg, M. A. Reidenbach. (2020). Drivers of Oyster Reef Ecosystem Metabolism Measured Across Multiple Timescales using the Non-Invasive Aquatic Eddy Covariance Technique. Estuaries and Coasts. Doi: 10.1007/s12237-020-00745-w.

March 2020

New paper on long-term trends and resilience of seagrass metabolism covering 115 full days of aquatic eddy covariance measurements. Rising ocean temperatures threaten seagrass meadows and their ability to hold carbon:

Berger, A., P. Berg, K. J. McGlathery, M. L. Delgard (2020). Long-term trends and resilience of seagrass metabolism: a decadal aquatic eddy covariance study. Limnology and Oceanography. Doi: 10.1002/lno.11397.

Listening to Data: Seagrass Sonification
On September 19-20th the Coastal Futures Conservatory led a field trip to the Virginia Coastal Reserve site and immersed us in a weekend of listening to the environmental surrounding us. The Conservatory aims to integrate arts and humanities and implement them in scientific inquiry.
Matthew Burtner, a composer and professor at UVA who is part of the Conservatory, seeks to create sonifications of ecological processes. He used seagrass metabolism data that we collected using the aquatic eddy covariance technique (Fig. 3; Berg et al. 2019) to create a song of photosynthesis and respiration. Listening to the recording, you can hear the harmonic progression through the days of the week, and the pitch changes that are caused by variations in oxygen production and consumption.

July 2019

New paper on links between seagrass metabolism and water column concentrations of O2 and CO2. This in situ study does not support the notion that seagrass meadows may be ‘winners’ in future oceans with elevated CO2 concentrations and more frequent temperature extremes:

Berg, P., Delgard, M. L., P. Polsenaere, K.J. McGlathery, S. C. Doney, A. C. Berger. (2019). Dynamics of benthic metabolism, O2, and pCO2 in a temperate seagrass meadow. Limnology and Oceanography. 64: 2586-2604.

Aquatic Eddy Covariance Featured in UVA Today
Our lab’s aquatic eddy covariance work in the seagrass meadows at the VCR LTER is featured in a University of Virginia video on coastal resilience. Measuring seagrass metabolism acts as a measure of restoration success and can help inform us on the carbon sequestration capacity of these ecosystems. Click here to watch: (original link).
