the NEPTUNE Canada fiber optic cable (IODP Expedition 328) represents the first of what should be a new generation of methane hydrate studies. A challenge unique to gas hydrate studies is development of sensors that can record natural changes in temperature, pressure, electrical resistivity, pore fluid flow rate, and other parameters without getting fouled by gas hydrate formation initiated by the presence of the sensor itself. Several attempts are currently under way to develop probes that could be deployed through scientific ocean drilling to operate in this challenging environment.
