Sensor-current
ADCP
Purpose
Shipboard ADCP survey of ebb tidal currents over middle
ground.  We will attempt to document both the cross-bank structure
of the tidal currents over 800 m  long across-bank transects.  We
will also attempt to measure the detailed vertical current structure
between two large sand waves (amplitude 2-4 m) over two wavelengths
(~150 m).
Information to be Derived
Vertical structure of currents and backscatter intensity
along shiptrack.  Surface water temperature along shiptrack.
Summary
We collected shipboard ADCP tidal currents over the ebb tidal
cycle (flowing toward SW) on middle ground.  We observed strong
lateral shear in the tidal currents caused by Middle Ground and
headlands along Martha s Vineyard.  We used Teladyne/RDI WinRiver II
software to collect the data, and this software produced two type of
files for each of the 6 transects we conducted: (1) a binary file
*.PD0 that contains raw information in beam/ship coordinates; (2) an
ASCII file *_GPS.TXT which contains the DGPS nav data.  Barry Irwin
also provided a RTK GPS nav file at 1 s intervals after the cruise.
Notes
RTK GPS data was not included in the data stream to the RDI
WinRiver II software.  Next time this should be included.
1 days at sea.
15 kms. of continuous data.
