our flagship project | the iLS (integrated Life System)
The iLS is an experimental life support platform intended to meet and evolve the demonstrated need to advance scientific diving. This project was inspired after a series of deepwater scientific activities principally conducted through NOAA's Caribbean Marine Research Center from 1999 through 2005. An iLS prototype was completed in early 2008, and is currently being demonstrated in a number of niche undersea operations, including utility in Ocean Opportunity field expeditions. Several new techniques, subsystem configurations, and aftermarket products have spun off of from the project. This information is being published in a series of white papers.

Student Internships The iLS Project's success has been made possible with the dedication of several student engineers over the years. The project continues to provide educational opportunities for students. Those interested are encouraged to contact us. more...

Rebreather Configuration

CEJN-style Offboard Q/D Subassembly With a growing population of rebreather divers, subsystem level components are in need of being standardized to enable cross-unit compatibility within a dive team. One such area, of critical importance, is cross-compatibility of offboard gas distribution systems. more...

Tips & Techniques

Advanced Hand Signal Communications for Technical Diving There are some 6000 languages of the world; an obvious barrier to overcome while working in the field. Generally speaking, underwater we rely exclusively on several universal hand signals. Here we propose a standardized set of underwater commands and values for advanced modes of diving. more...

Are you H.A.P.P.Y with your CCR at the water's edge? Predive systems and operations checks are critical to ensure proper functioning of your closed-circuit rebreather. With a number of unit variations on the market, this one simple and effective predive checklist, H.A.P.P.Y., will keep you covered. more...
