A gas capture device, called the methane bucket, was assembled and deployed on the Little Hercules. The methane bucket allows for estimating the volumetric flow rate associated with bubbles of methane gas at natural seeps. The methane forms a mix of hydrate (methane ice) and gas at depth but when brought to the surface the hydrate dissociates allowing measuring gas volume.
