Platform Manufacturer: NA, Platform Model: NA, Platform Serial Number: NONE; Instrument Manufacturer: Nortek, Instrument Model: Aquadopp Profiler 2MHz, Instrument Serial Number: AQD1954_ASP1667. This record refers to three (3) data files with the same name as this metadata file. The file with extension .ADP is the raw data uploaded from the instrument, including header information. Sontek ViewADPPro software was used to process the raw (.ADP) data and output a PUV.CDP file containing the raw time, pressure, horizontal and vertical velocity data and a WAV.CDP file containing mean wave burst (typically 1024 seconds in length) data of time, significant wave height, dominant period, mean U and V velocity. Files with extension .CDP (CRED Data Product) have had the header information, pre and post deployment data removed and a preliminary quality control conducted by plotting and reviewing the recorded data and removing obviously erroneous records. Each row corresponds to a data record. Data within the PUV.CDP file is supplied in columnar ASCII format: Column01: Year (UTC), Column02: Month (UTC), Column03: Day (UTC), Column04: Hour (UTC), Column05: Minute (UTC), Column06: Second (UTC), Column07: Pressure (lbs / inch^2), Column08: U eastward velocity (cm / second), Column09: V northward velocity (cm / second), Column10: W vertical velocity (cm / second). Data within the WAV.CDP file is supplied in columnar ASCII format: Column01: Year (UTC), Column02: Month (UTC), Column03: Day (UTC), Column04: Hour (UTC), Column05: Minute (UTC), Column06: Second (UTC), Column07: Significant wave height (meters), Column08: Dominant period (seconds), Column09: Mean U eastward velocity (cm / second), Column10: Mean V northwartd velocity (cm / second).
