Pop-up seabed seismic node
An autonomous seismic node is configured for free-fall from a water surface to the seabed and is capable of rising from the seabed on its own. The seismic node is positively buoyant in water and is substantially tubular in shape, with a length to a diameter ratio of 4:1 or greater. The node comprises a lower section and an upper section, each of which is inserted into an end of a tubular housing. The lower section has a lower end cap assembly with a release mechanism and the upper section has an upper end cap assembly with a plurality of electronic components and a detachable lifting cage. The seismic node may be coupled to a detachable anchor weight or seabed coupling device to assist in free fall to the seabed, and when detached after seismic recording is performed, allows the seismic node to rise to the water surface.
