Dr. Wethey's research includes the ecology of barnacles in the rocky intertidal zone, biophysical ecology in the intertidal and subtidal (heat, mass, and momentum transfer), predator-prey relations, conservation genetics of fish populations, and mathematical modeling of population dynamics. His interest in coral reef ecology began as a graduate student in the mid 1970s when he worked on photosynthesis and respiration in reef corals, including a NOAA saturation habitat mission at Hydrolab (the precursor of Aquarius) in Grand Bahama in 1974, and research at Discovery Bay in Jamaica, the Dry Tortugas in Florida, and Enewetak Atoll in the central Pacific Ocean. For those projects, he designed and built underwater instrumentation such as continuous-recording submersible respirometers for determining oxygen production and consumption of corals over 24 hour periods at depths of 60 feet. This required him to learn SCUBA, recompression chamber operation, electronics, machine tools (lathes and milling machines), and computer programming. Since then, he has deployed video cameras in the surf zone in the rocky intertidal to watch barnacle larval settlement behavior in real time, and has built portable weather stations for measuring micrometeorology of salt marshes and body temperatures of snails and clams. The Aquarius mission merges his interest in coral physiology with his recent work on the physics of mass transfer (advection and diffusion) in estuaries, done in collaboration with Aquarius team members Chris Finelli and Dean Pentcheff. Because he has not been diving since 1976, Dr. Wethey is a "dry investigator" on the mission, doing electronics repair, software support and repair, and other support from the mission communications center.
