New findings reveal that deep-sea methane deposits are converting into gas at a higher rate than previously observed and that a specific group of fossilized organisms possess the unique ability to detect these releases.scientist has devised a novel technique for tracking the conversion of deep-sea methane deposits into gas, as well as the upward migration of the gas toward the seafloor in quantities that were previously undetectable.
Miliolida foraminifera — Pyrgo spp., Quinqueloculina spp., and Spiroloculina spp. — are have the unique ability to sense small-scale methane dissociation events.

They are preserved in the sediment record and detected by the formation and presence of large carbonate nodules and a chemosynthetic community of organisms that develop at sites of methane release.
Methane hydrates are seen as an active research topic, often drawing wide scientific interest in developments surrounding them. There are numerous efforts assessing them as an energy resource and others as a contributor to greenhouse gases when released in sufficient quantities to make it from sediments into the atmosphere.
