Last September, NOAA Divers dove to the deepest depths any NOAA Diver has yet reached, down to a maximum of 300 feet, to survey areas around the North Western Hawaiian Islands.

NOAA Ship Hi‘ialakai conducted a 28-day research expedition in September to explore the deep reefs within Papahānaumokuākea Marine National Monument, recording marine life never before seen.

Study will help inform decisions on how to plan and conduct decompression diving.

NOAA Diver Brian Hauk and Reciprocity Diver Richard Pyle descend to a depth of 300 feet (an area also referred to as the twilight zone) on Pioneer Bank during research activities in the Papahānaumokuākea Marine National Monument. They are using closed circuit rebreathers.

The NOAA Diving Program partnered with Dr. Neal Pollock (center) to gather data on bubble formation in the hearts of divers conducting deep mixed gas dives on board the NOAA Ship Hi'ialakai during a September 2015 expedition. Working with him on this project were: Leah Potts (left) and Dr. Denise Blake (right).
