Abstract

This dataset presents the velocity and external sensor data recorded by the Nortek Vector ADV logger. The eddy covariance instrument was deployed July 11-17, 2017 in a subtropical inner shelf environment (Salinity: 35-36, temperature: 28-31°C) approximately 9 km south of Long Key in the Florida Keys (24° 43.52'N, 80° 49.85'W). The site was located at 9 ± 1 m water depth near the center of a large flat carbonate platform covered with coral sand. The measuring volume of the ADV was adjusted to be...

The Nortek Vector ADV logger was deployed July 11-17, 2017 in a subtropical inner shelf environment (Salinity: 35-36, temperature: 28-31°C) approximately 9 km south of Long Key in the Florida Keys (24° 43.52'N, 80° 49.85'W). The site was located at 9 ± 1 m water depth near the center of a large flat carbonate platform covered with coral sand. The measuring volume of the ADV was adjusted to be ~35 cm above the sediment-water interface.

The velocity data are unprocessed raw data as recorded by the Nortek Vector ADV using the following settings.
Sampling rate: 64 Hz, down-averaged to 8Hz
Nominal velocity range: 0.30 m/s
Burst interval: CONTINUOUS
Samples per burst: N/A
Sampling volume: 14.9 mm
Measurement load: 59 %
Transmit length: 4.0 mm
Receive length: 0.01 m
Number of beams: 3
Software version: 1.37.02

Measurements and data analysis are reported in Huettel et al. (2020).

Known Problems
Deployment 11-12 July: Measurements could not start before 14:00 due to bad weather preventing earlier deployment.
