Photosynthesis as a Possible Source of Gas Bubbles in Shallow Sandy Coastal Sediments
Abstract
Our long-term interests involve the possibility that biological activity can influence acoustic scattering at the water column-seabed interface and the propagation of sound in and over a sandy substrate in a shallow-water, coastal, marine environment. Evidence from laboratory studies on sand collected from the surf zone clearly demonstrates that gas bubbles can be formed when photosynthesis by benthic microalgae causes pore water to become supersaturated with oxygen.
