Mooring issues:
- ADCP deployed in non-vaned frame with viny floatation  
- biofouling light, transducers clear of barnacles
Instrument issues:
- failed following tests in air pre deployment: none
- failed following tests in air post deployment: WB
Data issues:   
- pitch and roll generally < 10 deg, peaking at 20 deg
- roll frequently 5-10deg
- range measurements not corrected for pitch and roll
- large errors in bin1, and at start of record
- data generally good until Bin16 (~12m) 
- temperature data not quality controlled
Project:
- part of Woodgate Bering Strait NSF-AON project.
