Purpose. This chapter explains the special requirements for ice and cold water
Scope. Polar regions and other cold weather environments are uniquely hostile to
divers, topside support personnel, and equipment. Diving where ice cover is
present can be extremely hazardous and requires special equipment as well as
appropriate operating and support procedures. Awareness of environmental conditions,
personnel and equipment selection, and adequate logistical support are vital
to mission success and dive team safety.
