    dct:description "For the first time in Australia, active present-day hydrocarbon seepage has been imaged on the tropical carbonate Yampi Shelf, in 50 and 90 m water depth. Seepage features consist of gas plumes in the water column associated with specific seabed features, such as clusters of reflective blocks, hard-grounds, pockmark fields and mounds. Seepage activity and intensity appear to vary with changes in pressure related to macro-tidal cycles. The seabed features coincide with sub-surface features such as areas of seismic signal attenuation under high amplitude reflectors, seismic discontinuities and bright spots. Hydrocarbon migration-seepage pathways appear to be controlled by the reactivation of pre-existing fractures and dykes within the basement. The types of seabed features and their preservation on a tropical carbonate shelf are strongly influenced by the coarse bioclastic nature of sediments and the high energy of macro-tidal currents and storm reworking." ;
