In 2023, comprehensive studies of shallow-water methane gas emissions were conducted during expeditionary work in the coastal area Laspi Bay (southwestern coast Crimea). The research included determining component and isotopic composition bubble gas, measuring concentration emission area, estimating flux rates, hydrophysical parameters above seep site. obtained results carbon ethane studied samples corresponded to (δ 13 C mean = –36.0 ± 0.8‰, δ –37.5 0.2‰, respectively) indicate presence...
This research quantifies the gas release rate from a natural shallow methane seep site in Laspi Bay (Black Sea), whose origin is thermocatalytic. An adaptive single bubble identification technique was applied to analyze volume and rates passive acoustic data. Gas seafloor emitted by bubbles that occurred clusters. The frequency of an individual (830 Hz) proportional bubble's radius (0.4 cm), which coincides with optical method. active seepage phases lasted longer than pauses between...

This work is devoted to studies of the shallow methane seepages temporal variability in coastal area Laspi Bay and high-frequency monitoring hydrological parameters daily dynamics this area. The paper presents results obtained during summer months 2016, 2018-2021, early February 2023. Using passive acoustic method, it shown that intensity periodicity bubble gas emission by individual point sources can vary day from season season. It was a decreased content dissolved oxygen its saturation...
