map gas in sediments and water column in vicinity of lake-bottom sonar deployment
Location
Upper Mystic Lake, Massachusetts
Summary
Re-occupied closely spaced Chirp lines collected earlier to determine if any changes in gas charging of sediments or gas emissions from sediments. Crossed sonar deployed on bottom lander several times and imaged it in the Chirp data. Sought to correlate seeps detected by the sonar lander with seeps inferred from fishfinder/Chirp records.
