## Aquarius and NEEMO

In October 2001, Hulsbeck took part as a habitat technician in the NASA Extreme Environment Mission Operations 1 mission (NEEMO 1), the first of a series of NASA-NOAA missions which use Aquarius as an analog environment for space exploration. The NEEMO 1 crew lived and worked underwater aboard Aquarius for seven days. In July 2006, Hulsbeck served as a habitat technician during the NEEMO 10 mission, the crew of which also lived underwater for seven days. Hulsbeck's other missions aboard Aquarius have included a June 2004 coral reef study led by Dr. James Leichter of the Scripps Institution of Oceanography and an October 2007 mission studying the role of sponges in coastal nitrogen cycles. Hulsbeck had taken part in nineteen Aquarius missions as of July 2011. In June and July 2014, Hulsbeck served as lead habitat technician aboard Aquarius during Fabien Cousteau's Mission 31 expedition, living and working underwater for 31 days.
In May 2007, Hulsbeck and other NURP/UNCW divers, including fellow Aquarius divers James Talacek and Jim Buckley, set up a coral monitoring station pylon offshore from the Discovery Bay Marine Laboratory in Discovery Bay, Jamaica, for a cooperative program among Caribbean countries called Mainstreaming Adaptation to Climate Change (MACC). The station was part of NOAA's Integrated Coral Observing Network (ICON). The station was subsequently destroyed during Hurricane Paloma in November 2008.
