ADCP velocity, echo intensity, and compass heading from two near-bottom moorings in the south equatorial Atlantic Ocean from 2009-12-01 to 2010-03-23 (NCEI Accession 0209071)
Preview graphic
This dataset contains ADCP velocity, echo intensity, and compass heading from two near-bottom moorings in the south equatorial Atlantic Ocean in the Congo submarine canyon during ~3 month period from 2009-12-01 to 2010-03-23. Two ADCPs with acoustic frequencies of 300 kHz and 75 kHz were deployed on separate moorings placed in the channel axis 700 m apart and at ~2000 m water depth. They acquired data over a range of ~80 m above the seafloor (300 kHz) and 220 m above the seafloor (75 kHz). Data are in netcdf.

Processing Steps |
- Parameter or Variable: Flow Speed (measured); Units: m/s; Observation Category: in situ; Sampling Instrument: ADCP 75 kHz and 300 kHz; Sampling and Analyzing Method: Data were acquired in the Congo submarine canyon over a ~3 month period in 2010. Two ADCPs with acoustic frequencies of 300 kHz and 75 kHz were deployed on separate moorings placed in the channel axis 700 m apart and at ~2000 m water depth. They acquired data over a range of ~80 m above the seafloor (300 kHz) and 220 m above the seafloor (75 kHz) at profileing intervals of 5 s (300 kHz) and 6 s (75 kHz).; Data Quality Method: Velocity data were discarded by the instruments when correlation values dropped below 64 counts or when the ambiguity velocity was greater than 2 m/s.
