The Integrated Coral Observing Network (ICON) program has constructed and installed a series of Coral Reef Early Warning System (CREWS) stations which provide a wealth of high-quality meteorological and oceanographic data in near real-time. CREWS stations date back to 2001 with the deployment of an early buoy-type design in the Bahamas. Beginning in 2002, the program shifted to a pylon-type design which was re-engineered in 2005, resulting in the modern CREWS stations found in the Bahamas, Puerto Rico, the US Virgin Islands and Little Cayman. The basic CREWS instrumentation architecture described by Jankulak et al (2009) has evolved over time into a robust package that, combined with a regimen of regular instrument cleaning and recalibration, has yielded a continuous, long-term, high-quality dataset from these harsh marine environments.

Additional instruments are added as research need arises. For instance, a Pulse-Amplitude-Modulating (PAM) Flurorometer was utilized for bleaching studies in 2005 at Lee Stocking Island Bahamas. For a more complete discussion and retrieval of that document, refer to Manzello et al (2009).
