Preliminary results of the SOPRAN seawater gas exchange experiment in the Heidelberg Aeolotron
In November of 2014, air-sea gas exchange measurements using natural seawater taken from the North Atlantic were performed at the large annular wind-wave tank in Heidelberg, the Aeolotron, within the BMBF project SOPRAN (Surface Ocean Processes in the Anthropocene). Gas exchange experiments with of...
