This report contains data from R/V Sikuliaq cruise SKQ201617S to the eastern tropical north pacific oxygen deficient zone. The objective of the cruise was to study denitrification and anammox processes. The cruise took place between December 2016 and January 2017 in an area bounded by 25N-14N and 112W-104W. Two data sets are included. The first is the 1-meter binned CTD data while the second is the bottle cast data and contains nutrient values for nitrate, nitrite, silicate, phosphate and ammonium. The data were collected as part of NSF grant number 1542240 to Gabrielle Rocap, Rick Keil, Allan Devol, and Curtis Deutsch. CTD data has been reprocessed and aligned and outliers have been removed. Nutrient samples were filtered (GFF glass fiber) before analysis and analyzed using the US-JGOFS protocols (http://usjgofs.whoi.edu/protocols_rpt_19.html). All data are considered final. Data files provided in CSV format.

This dataset contains water temperature, salinity, dissolved oxygen, and chlorophyll taken by CTD and water samples in cruise SKQ201806S by the research vessel Sikuliaq in the northeastern Pacific off California coast during 2018-03-13 2018-03-16. The cruise had the objective to service the California Current Ecosystem CCE2 mooring. To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files will become available through the Rolling Deck to Repository (R2R) program, and the water sample data through the Ocean Carbon and Acidification Data Portal at NCEI. Data are in netCDF format.

This dataset contains water temperature, salinity, and other parameters collected by CTD from research vessel Sally Ride, cruises SR1706 and SR1707, offshore California from 2017-03-05 to 2017-03-11. These cruises had, among others, the objective to service the CCE2 mooring (California Current Ecosystem). To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD data are reported here. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are available through the Rolling Deck to Repository (R2R) program, and the water sample data will be published via the Ocean Carbon and Acidification Data Portal at NCEI. Data are in netcdf format.

This dataset contains water temperature, salinity, and other parameters collected by CTD from research vessel Sikuliaq, cruise SKQ201606S, in the north Pacific Ocean off California. Cruise SKQ201606S by research vessel Sikuliaq in May 2016 had the objective to service moorings for the CCE (California Current Ecosystem) project. To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are available through the Rolling Deck to Repository (R2R) program under accession 0162416, and the water sample data will be published through the Ocean Carbon and Acidification Data Portal at NCEI. Data are in NetCDF.

This dataset contains water temperature, salinity, and other parameters collected by CTD from research vessel Sikuliaq, cruise SKQ201912S, in the north Pacific Ocean off California. Cruise SKQ201912S by research vessel Sikuliaq in May 2019 had the objective to service moorings for the CCE (California Current Ecosystem) and CORC (Consortium on the Ocean's Role in Climate) projects. To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data. The raw CTD data files will become available through the Rolling Deck to Repository (R2R) program, and the water sample data through the Ocean Carbon and Acidification Data Portal at NCEI. Data are in NetCDF.

The dataset of water temperature, and salinity profiles were taken by CTD during the Pacific Oceanographic Cruise XLII, developed on September 15th and 17th, 2006, by the Pacific Pollution Control Center (CCCP) of the General Maritime Directorate (DIMAR), aboard the research vessel ARC Providencia, covering 19 stations located throughout the basin Colombian Pacific, with the objective to determine the variability of the physical and chemical conditions of this area. Data are in CSV format.

The dataset of water temperature, salinity and oxygen CTD profiles was obtained during the Pacific Oceanographic Cruise XXXIX / Regional Study of the El Niño Event ERFEN XXXVII, developed between September 10th and October 8th, 2004, by the Pacific Pollution Control Center (CCCP) of the General Maritime Directorate (DIMAR), aboard the research vessel ARC Providencia, covering 41 stations located throughout the Colombian Pacific basin, with the objective to analyze the behavior of meteorological, oceanographic, chemical and biological parameters in this area. Data are in CSV format.

The dataset of water temperature, and salinity profiles taken by CTD during the Pacific Oceanographic Cruise XXXIII / ERFEN XXXI, conducted between November 19th and December 6th, 2000, by the Pacific Pollution Control Center (CCCP) of the General Maritime Directorate (DIMAR), aboard the research vessel ARC Providencia, covering 56 stations located throughout the Colombian Pacific basin, with the purpose of characterizing the variation of the physical, chemical, and biological parameters of the ocean, and relating them to anomalies of an El Niño phenomenon. Data are in CSV format.
