Title:
ADCP Wave and Current Data from OB27, Coastal Ocean Research and Monitoring Program, Onslow Bay, North Carolina, December 2004
Abstract:
An upward looking wave-upgraded ADCP was moored on the bottom at station OB27 in Onslow Bay, North Carolina at 27 m depth on the continental shelf. Current data are sampled over one minute periods every 15 minutes, so the sample interval is 15 minutes. Depth bins are one meter. The first bin is centered at 24.5 m depth and subsequent bins are spaced at one meter intervals above that. The last couple of bins are above the surface, and so are not useful. Waves bursts were collected every 2 hours. Each burst contains 2400 samples collected at 2 Hz. Processing was done by Frederick M. Bingham, a professor of phyics at UNC Wilmington. Raw ADCP files were extracted from the instrument. Data have not been quality controlled in any way. This metadata record describes the raw file downloaded directly from the instrument.
Supplemental_Information: Sensor name: RDI Workhorse Sentinel, 600 kHz.
