Benthic O2 uptake of two cold-water coral communities estimated with the non-invasive eddy correlation technique
© The authors 2015. The community respiration of 2 tidally dominated cold-water coral (CWC) sites was estimated using the non-invasive eddy correlation (EC) technique. The first site, Mingulay Reef Complex, was a rock ridge located in the Sea of Hebrides off Scotland at a depth of 128 m and the seco...
