New 600 kHz Aquadopp Z-Cell Profiler Deployed by CariCOOS

The first 600 kHz Aquadopp Z-Cell Profilers, featuring 50m of profiling range and NO BLANKING DISTANCE were sent to researchers with the Caribbean Coastal Ocean Observing Regional Association at the University of Puerto Rico Mayaguez early this year and the first is operational with real-time buoy data available to the public.

CariCOOS buoy deployed at station PR1.

Last Fall researchers at the University of Puerto Rico Mayaguez approached NortekUSA for recommendations for the Caribbean Regional Association’s second CariCOOS data buoy to be deployed off the North coast of Puerto Rico.  Several issues involving water depth and difficulty of access precluded the use of a bottom mounted system.  They planned to use an inertial system aboard the buoy to measure waves, but still required a profiling system for their 30m range and currents near the surface were also important to them.  Thoughts were to use a current profiler and either sacrifice surface currents or install a single point current meter at the buoy.  As luck would have it, Nortek was just about to release the 1 MHz Z-Cell Aquadopp Profiler after very favorable data from prototype testing.  The University was very interested, however, the 20m range of the 1 MHz system was just too short for their application.  In keeping with Nortek corporate culture, we took into account the needs of these highly regarded clients as well as other Nortek users in a similar predicament and moved to develop the 600kHz version of the Z-Cell Aquadopp Profiler.  The lower frequency was made available in time for winter development and spring deployment of the CariCOOS buoy.  The researchers decided to fit their first buoy, deployed Summer 2009, with the 600 kHz Aquadopp Z-cell and real-time data from this buoy may be viewed at http://gyre.umeoce.maine.edu/caricoos/.  Deployment of the second buoy is scheduled for this month.
