Description

Profile data from WireWalker deployments at Mission Beach, California in 2016 at a 50m depth.

The default data format served through the BCO-DMO data system is tabular. These data are available to download as matrices in NetCDF (.nc) and Matlab (.mat) files in the "Data Files" section of this page.

Methods & Sampling

Instruments were mounted on a WireWalker profiler (http://delmarocean.com/wirewalker/) and data collected during ascent only. The interval between profiles was dependent on sea state. The WireWalker instrument was deployed on 50-m depth contour off Mission Beach, CA near a thermistor chain and in line with Internal Waves on the Continental Margin (IWAVES) stations. For more information about IWAVES stations see Lerczark, 2001.

Data Processing Description

Data interpolated on common depth and time grid.

Issues: Aquadopp data was corrupted and so was omitted.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values in this dataset are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system.
* created tabular version of data by converting Matlab struct to a Matlab Table type then exported as csv.
* rounded matlab double values to three decimal places before writing to csv.
* On the first day (2018-06-13) records are ommitted in the tabular version of the data. All values (except depth &time) were NaN values.
