SEA PROFILER3

Single and Dual Frequency ADCPs for Ocean Monitoring and Surveys.

The SEA PROFILER3 3^rd generation ROWE ADCP Technologies employ a common core of multiple-frequency electronics and firmware modules, and dual-frequency Piston-array or Phased-array transducers to simultaneously measure precision and short Range and Long Range vertical profiles of 3-Axis Currents, Echo Intensity, Plankton mass and Size Distribution, plus bottom track and altitude, providing:

A single SEA PROFILER3 ADCP has 4 or 5 Janus Configuration BEAM sets with each set operating at acoustic frequencies differing by a factor of 4. A video animation illustrating the Dual-frequency generation from a single transducer is shown on the right for reference. The lower frequency provides longer profiling range, and the higher frequency provides higher spatial, velocity and temporal resolution currents and echoes nearer to the ADCP- equivalent to 2 single-frequency ADCPs but physically and functionally integrated in a single unit.

The Direct-Read (DR) ADCPs can also be converted to a Self-Contained unit (SC) by attaching a modular plug-in battery pack. A video animation is shown on the right that illustrates the conversion from Direct-Read (DR) unit to Self-Contained (SC) unit.

Optional transducer configurations available are:

• Single Frequency piston arrays of 75, 150, 300, 600, 1200, 2400 kHz.
• Dual Frequency piston arrays of 75/300, 150/600, 300/1200, 600/2400 kHz.
• Single Frequency Phased arrays of 38, 75, 150, 300 kHz.
• Dual Frequency Phased arrays of 38/150, 38/300, 75/150, 150/300 kHz.
• Single and Dual frequency vertical beams of 150, 300, 600, 1200, 150/300, 300/1200, 600/2400 kHz.
