Data Attributes

![]() |
Name | Type | Description |
---|---|---|---|---|
100
|
UTCDateTime | Date/Time | UTC date and time of ADCP measurement (m/d/yyyy h:mm:ss), collected at 10-minute intervals. | |
100
|
HeightBin_m | NUMERIC | Height bin above the ADCP. Each height bin is represented as the upper limit of the bin height above the sensor on the seafloor (for example, a 1.4 m bin represents current data collected between 0.4 m and 1.4 m above the ADCP). ADCP data include a blanking region, or a small distance in front of the transducer in which measurements cannot be made, of 0.2-0.4 m, and grouped into 1-m height bins. | |
100
|
Speed_ms | NUMERIC | Current magnitude (speed), measured in meters per second. Calculated as the square root of the sum of the squared u and v velocities. Data are trimmed to a maximum height bin for each time interval using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides. | |
100
|
Direction_deg | NUMERIC | Current direction, measured in degrees (0-360). Data are trimmed to a maximum height bin for each time interval using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides. |
