Abstract:

The long-term goals of this research are to do the following 1 to assess the role of small gas bubbles in shallow sandy coastal sediment for sediment geotechnical properties, the transport of solutes across the sediment-water interface and the biogeochemical processes in the sediment surface layer and 2 to develop and apply an acoustic technique for the detection and quantification of small gas bubbles in sandy sediment at a high spatial resolution. The specific objectives of this research are to do the following 1 Quantification of small gas bubbles in the surface layer of coastal sand sediment and assessment of their temporal and spatial distribution, 2 Quantification of the volumes and composition of the gas bubbles in the sediment and the overlying water and the changes of volume and composition over time, 3 Measure the dispersion and transport of solutes caused by bubble volume change and migration under different pressure conditions, and 4 Develop and apply an acoustic technique with high spatial and temporal resolution for the detection and quantification of embedded gas bubbles.
