    Research Statement
     (1) Oceanic gas hydrates: Clathrate hydrates of gas (gas hydrates) are crystalline substances composed of water and certain gases (usually methane) that occur naturally in pore space of marine sediment. These hydrates are of interest because they represent a potential future energy resource and modulator of climate change. My research has included studies on the distribution and composition of gas hydrate in sediment columns, experimental work on the thermodynamic conditions of gas hydrate formation and dissociation, and numerical models pertaining to the release of methane into the ocean and atmosphere.

    (2) Geochemical cycling during major oceanographic change: This pursuit involves the construction of chemical profiles in marine sediment across critical time intervals in the evolution of our ocean. Previous work has included trace element profiles across the Cenomanian/Turonian and Miocene/Pliocene boundaries. Currently I am working toward
    understanding events in the early Paleogene (Paleocene-middle Eocene) and early Aptian, times characterized by major wamrth and massive input of carbon.

    (3) Sediment-hosted metalliferous ore deposits: marine sedimentary rocks are the host to large ore deposits of certain metals, including iron, manganese, vanadium and barium (e.g., ores of Fe, V, Ba). In most cases, these deposits result from the combination of unusual paleoceanographic conditions and subsequent weathering or alteration processes. My current research in this area focuses on the origin of BIF hosted iron ores and black-shale hosted vanadium ores in Australia.

    (4) Mixed siliciclastic/carbonate margins: Many continental margins, both modern and ancient, receive significant amounts of terrigenous clastic and shallow marine carbonate sediment. These mixed siliciclastic/carbonate depositional systems have not been well-studied in the past. The North Queensland margin of Australia is the largest extant mixed clastic/carbonate system. Currently I am quantifying sediment deposition on this margin with the aim of establishing a flux-based model of accumulation.
