A self-mooring module. In particular, a self-mooring module that may be deployed by air, surface or underwater. The module includes a combination anchor/air brake, a buoy, and a mooring line. The module may also include a sensor module. The anchor, combination anchor/air brake and buoy may be used in combination as part of the module or may be used alone in different aspects. The anchor and combination anchor/air brake are foldable to conserve space. The buoy has reduced drag and increased stability versus regular buoys. The self-mooring module may also include an intelligent mooring line module that determines the amount of mooring line to be released for a particular mooring depth and does not release a substantive amount of extra or insufficient mooring line, thereby helping ensure proper placement of an sensor module. Other features include a release mechanism for releasing the anchor from the module and a mechanism for inflating the buoy.
