Various forms of corrosion experienced on deep sea buoys and moorings are discussed. The corrosion occurred on actual field deployments of buoys and moorings operated by the National Oceanic and Atmospheric Administration’s National Data Buoy Center.

For each corrosion phenomenon case presented, a possible mechanism based on corrosion theory is submitted as an explanation of the type and severity of corrosion experienced. Crevice, pitting, and galvanic types of corrosion are discussed.

The importance of proper material selection and the understanding of materials and their limitations in seawater applications is emphasized as a summary to the reported cases.
