We at NUMA pride ourselves on our prompt response time to your letters and phone calls. However, as you know, NUMA is a 501c3 non-profit with no full-time staff. The majority of funding (more than 95%) for NUMA comes from royalties from Clive Cussler’s best-selling novels. In order to keep those funds focused on preserving our maritime history, we have devised this page of commonly asked questions and answers to help reduce administrative overhead for NUMA.

How do I find out about employment opportunities or volunteering with NUMA?

NUMA is a 501c3 non-profit. As such, NUMA has no full-time staff but only uses staff on an as needed basis. The divers who work for NUMA are a trusted and loyal crew that have been with Clive Cussler since NUMA’s inception in 1979. Because ours is a litigious society and searching for ships and planes is more dangerous than one might think, our legal advisers have told us that we cannot use volunteers on our NUMA expeditions. NUMA is a 501c3 non-profit.
