Description

Temperature from a thermistor chain deployed along a 30m depth contour at Mission Beach, CA in June of 2016. Water temperatures are measured values at each instrument height, interpolated on a common time grid.

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

A vertical array of thermistors was deployed on the 30-m depth contour off Mission Beach, CA in line with Internal Waves on the Continental Margin (IWAVES) stations. For more information about IWAVES stations see Lerczark, 2001. Thermistors were spaced 1-m apart in the vertical. One thermistor was added at the surface. See Tchain30_MooringSchematic.pdf for a diagram of the thermistor configuration and serial numbers. Depth values in this schematic are the target deployment depths and vary from the measured values due to tidal fluctuations.

Data Processing Description

RBRsolo s/n 10174 and 10178, and SBE56 s/n 00345 were either lost from entanglement with fishing boat or did not record data. Unix timestamp derived using RSKtool datenum2unixtime(), time steps should be 1 s, but varies between 0, 1, and 2 s. Use start time and add 1 s if needed.

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.
