IADC depends in many instances on the input of its members. To that end, several committees have been established. These include the following committees:

IADC Public Relations Committee

The committee meets four times a year in various venues and members are on-call in between for consultation. They contribute ideas for IADC to further its PR activities, including providing lecturers for IADC seminars and advising about articles for Terra et Aqua Journal, the Facts About series and other IADC publications.
