From the press release: «During field expeditions, the research team used a variety of techniques — including sonar and visual images of methane bubbles in the water, air and water sampling, seafloor drilling and temperature readings — to determine the conditions of the water and permafrost, as well as the amount of methane being released.»

Seafloor volcanoes usually emit lobes and sheets of lava during an eruption, rather than explosive plumes of gas, steam, and rock that are ejected from land - based volcanoes.
