In addition to the tabular form of this dataset available by clicking the "Get Data" button on this page, it is also available as a Matlab (*.mat) file containing data matrices and vectors. See the "Supplemental Files" section on this page for the data in this form along with the matlab m-file used to transform the data matrices to a tabular dataset.

Methods & Sampling

Dataset acquisition description

Glider deployment: For this study, a slocum glider was deployed between March and July in 2013 and 2014 in the San Pedro Channel, located in the Southern California Bight off the coast of Los Angeles. The glider was deployed on a 28 km cross-channel path between Catalina Island and the Palos Verdes Peninsula and completed a single cross-channel pass every 1.5–2 days (average speed 1 km h−1). Data were collected between ∼ 3 and 90 m, with the exception of when the glider crossed the major shipping lanes where the glider was constrained to depths below 20 m to avoid damage or loss from ship traffic. The GMT time stamp indicates the earliest time stamp for data binned within a single profile. Glider deployments were from small boats belonging to the USC Wrigley Marine Sciences Center or from the R/V Yellowfin.

Optode oxygen concentration was corrected for measurement lag and calibrated using Winkler titrations.

Data Processing Description

Dataset Processing Description

BCO-DMO Data Manager Processing Notes: Data Version 1: 2018-12-14
* tabular dataset constructed from original .mat data file
* tabular dataset imported into the BCO-DMO data system with added header with dataset name, PI name, version date.
* orignal matlab file served as a downloadable link on this dataset landing page.
* blank values in the BCO-DMO data system are displayed as "nd" for "no data." nd is the default missing data identifier in the BCO-DMO system. Blank values in the original .mat file are the matlab default value NaN.

BCO-DMO Data Manager Processing Notes: Data Version 2: 2019-07-03
* Same processing performed on version 1 as version 1.
* New version had lat/lon values corrected by the data submitter.
* Version 2 has column OXYGEN which was called O2 in version 1.
