A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.

A vertical marker buoy and method for deployment are disclosed herein for enhanced detection of equipment on the water's surface. The equipment may have been previously submerged at a significant depth. The buoy and method provide a faster and more reliable means to locate equipment, e. g., at the sea surface or suspended by a float. The marker buoy has flotation device, a detection indicator and a bail mounted to a tube. The marker buoy is configured to be positioned in a substantially vertical position when the vertical marker buoy is in use on the surface of a body of water. The vertical marker buoy is capable of being deployed at an underwater depth.
