Bottom line for hydrocarbons

Article Abstract:

Dickens et al. found evidence suggesting that there may be a very large deposit of hydrocarbon under the ocean floor. The pool of organic carbon may be greater than the world's oil reserves and may be able to interact with the atmosphere to cause climatic changes. Samples of material from a bottom-simulating reflector at Blake ridge in the Atlantic Ocean indicate that hydrate is present in about 0-9% while gas is present in about 12% of pore volume in the two zones examined.

Diamondoid hydrocarbons as indicators of natural oil cracking

Article Abstract:

Oil cracking occurs within oil-bearing rock formations in a process that ultimately converts oil into gas and pyrobitumen. Cracking experiments imply that petroleum is more stable thermally than previously thought, and liquid petroleum may persist at temperatures reaching or exceeding 200 degrees C. The relative abundance of diamondoids, petroleum compounds with unique thermal stability, can be used to identify oil destruction and the oil deadline in a particular basin.

Back to the bottom

Article Abstract:

Marine scientists are getting ready for their newest tool, a versatile robot submersible that can travel into the ocean's deepest abyss. A visit to the Woods Hole Oceanographic Institution (WHOI) in Massachusetts where the future of deep-sea exploration is being designed is discussed while the engineers plan to have the vehicles in the water by 2007.
