Dataset: Water temperature, salinity, and other data from CTD taken from the RV Sikuliaq in the Pacific Ocean between San Diego, California and Manzanillo, Mexico from 2016-12-21 to 2017-01-13.

Hydrographic data were collected using a Seabird CTD Niskin Bottle Rosette, deployed at a wire speed between 40 and 60 meters per minute. 

Nutrient samples were filtered (GFF glass fiber) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html) at the UW Marine Chemistry Laboratory.

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. 

CTD data were processed using Seabird proprietary data conversion software and factory calibration coefficients; dissolved oxygen voltage was aligned using a time advance of 2.33 seconds; downcast data were averaged into 1 meter bins. CTD data has been reprocessed and aligned and outliers have been removed. All data are considered final.

This data is available at National Centers for Environmental Information (NCEI).
