The anchor consists of two railroad wheels. A chain is attached to the anchor. An a-frame hoist lifts the anchor to the surface of the ocean. This is the instrument that releases the mooring for recovery. The instruments must be recovered so the year's data can be downloaded.
More chain is attached along with a double glass ball float encased in a hard hat of yellow plastic.
Red synthetic rope is hooked to the chain and an instrument is attached. The rope makes it easier to attach the instruments with tie-wraps. Anything that turns can work its way loose in the constantly moving ocean. As a result, all the plastic tie-wraps are secured with black tape. Anything held by a bolt and nut is secured with a cotter pin.
