ADCP Gothenburg 2018

Note: This is the first version of the data set where vertical beam velocities are missing. Use version 2: 10.5281/zenodo.10846812

A bottom mounted mooring with a fixed upward-looking Nortek Signature 500 ADCP was deployed under the ship lane to Gothenburg Harbour at 32 m depth, position (57.61178 N, 11.66102 E) in the period 28 August to 25 September 2018. The ADCP was set up to measure and store single ping, along beam current velocities, using four slanted beams (25° angle) and one vertical beam (ping frequency 1 Hz, vertical cell size 1 m on all beams). The instrument was set up with 38 bins numbered from 1 to 38 with #1 closest to the instrument centered 1 m above the transducers.

The data set contains raw data from the instrument, converted to csv format with the Nortek Deployment software.

Processing: This is raw data, so no processing has been performed.

Notes:

- Beam #2 is not working, so those data do not make sense.

- Data from about 10% of the depth below the surface and above should not be used.
