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 clearly demonstrates that gas bubbles can be formed when photosynthesis by benthic microalgae causes pore water in sand collected from the surf zone to become supersaturated with oxygen.
