Beginning in 2011 the University National Oceanographic Laboratory System (UNOLS) began a program of Chief Scientist training cruises to introduce prospective early career scientists to the process of planning, acquiring, effectively utilizing, and reporting on time at sea for multi-disciplinary research and education. Cruise TN338 of R/V Thomas G. Thompson to the California Borderland Basins area was the seventh of such cruises and collected water column data using a SeaBird CTD/Rosette. Presented here are the temperature, salinity, and bottle data from those CTD casts.

The training cruise occurred between February 12 and 19 in 2016. Chief scientist trainees self-organized into a water-column group studying the upwelling surrounding Cherry Bank, another group study along a section roughly normal to the coast and a benthic group. Collected here are the water temperature, salinity, dissolved oxygen, chlorophyll fluorescence, transmissometry, nitrate, nitrite, ammonia, phosphate, and silicate data.

Hydrographic data were collected using a Seabird CTD Niskin Bottle Rosesett, deployed at a wire speed between 40 and 60 meters per minute. The Seabird CTD Niskin Bottle Rosette included the following sensors: Seabird 911 Conductivity Temperature Density meter; Seabird SBE 43 Dissolved Oxygen Sensor; WETLabs ECO Chlorophyll Fluorometer; Biospherical/Licor PAR/Irradiance Sensor; WETLabs C-Star Transmissometer. Water samples for dissolved Oxygen concentration, Nitrate, Nitrite, Phosphate, Ammonium, and Silicate were taken from the 5 L Niskin bottles. Nutrient samples were filtered (GFF glass fiber) before analysis, and all water samples were analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html).

CTD data were processed using Seabird proprietary data conversion software and factory calibration coefficients; dissolved oxygen voltage was aligned using a time advance of 3.5 seconds; downcast data were averaged into 1 meter bins. Dissolved oxygen concentration was corrected using Winkler titrations of bottle data. CTD data has been reprocessed and aligned and outliers have been removed. The Seabird SBE 43 data were calibrated against Winkler dissolved oxygen titration data at selected depths and stations. All data are considered final.
Purpose This report presents data collected as part of a cruise designed to train young investigators how to plan, organize and carry out a oceanographic cruise on a UNOLS vessel.
