Atmospheric methane flux from bubbling seeps: Spatially extrapolated quantification from a Black Sea shelf area
Journal: Journal of Geophysical Research Atmospheres

Bubble transport of methane from shallow seep sites in the Black Sea west of the Crimea Peninsula between 70 and 112 m water depth has been studied by extrapolation of results gained through different hydroacoustic methods and direct sampling. Ship‐based hydroacoustic echo sounders can locate bubble releasing seep sites very precisely and facilitate their correlation with geological or other features at the seafloor. Here, the backscatter strength of a multibeam system was integrated with single
