Diving Program

Tethered Communications

Objective: Prepare NOAA Divers and topside support personnel to safely conduct diving operations using tethered communications.

Note: The NOAA Diving Program (NDP) provides training primarily to NOAA employees that are authorized by their supervisors to dive as part of their job description. However, NDP also welcomes federal, state, and local government employees for a fee into its courses as space permits. Please contact NDP Support(link sends e-mail) for updated fees if you are not a NOAA employee. Classes are not open to the public.

Upcoming course dates can be found on the website calendar, or on this Google Calendar.

All students learn how to use specialized equipment and practice using them in various roles that include topside tender, standby diver, and diver.
