Methane and minor oil macro-seep systems—their complexity and environmental significance
M Hovland, S Jensen, C Fichler - Marine Geology, 2012 - Elsevier
The two main observations characterising marine and lacustrine methane macro-seeps are
ebullition through holes in the sea-or lake-bed, and hydroacoustic “flares” in the water …
