Potential of Direct and Indirect Impacts. Based on the analysis of the potential acoustic impacts conducted for the ACOBAR Experiment, there are no identified direct or indirect impacts that resulted from the experiment activities, including the acoustic transmissions that occurred during the experiment. No lasting direct or indirect physical impacts resulted from the experiment.
