Chemical, physical, and other data were collected using bottle casts in the North Pacific Ocean from January 6, 1951 to October 31, 1960. Data were submitted by Scripps Institution of Oceanography as part of the California Cooperative Fisheries Investigation (CALCOFI) project.

Temperature, salinity, physical, chemical, and other data were collected using moored bottle casts in the Coastal Waters of California from the SAMPSON from August 1, 1999 to October 1, 1999. These data were submitted by Scripps Institution of Oceanography, LA JOLLA, CA.

Chemical data were collected using bottle casts from multiple vessels in the Arctic Ocean and other Sea areas from 16 April 1948 to 17 September 2000. Data were submitted by the University of Alaska in Fairbanks, Alaska. Chemical data include alkalinity, nitrate, nitrite, oxygen, silicate, and phosphate.

Chemical, physical, and other data were collected using bottle, BT, current meter, MBT, meteorological sensors, and Secchi disk casts from January 1, 1968 to December 4, 1968. Data were submitted by Stanford University; Hopkins Marine Station as part of the California Cooperative Fisheries Investigation (CALCOFI) project. Data were processed by NODC to the NODC standard F004 water physics and chemistry format. The F004 format contains data from measurements and analysis of physical and chemical characteristics of the water column. Chemical parameters that may be recorded are salinity, pH and concentration of oxygen, ammonia, nitrate, phosphate, chlorophyll and suspended solids. Physical parameters that may be recorded include temperature, density (sigma-t), transmissivity and current velocity (east-west and north-south components). Cruise and station information may include environmental conditions of the study site at the time of observation. Data are very sparse prior to 1951.

Bottle data collected during CalCOFI cruises 1701, 1704, 1708, 1711, 1802, and 1804, January 2017 - April 2018. The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish & Wildlife, NOAA Fisheries Service, and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Niño and climate change. CalCOFI conducts quarterly cruises off southern & central California, collecting a suite of hydrographic and biological data on station and underway.

Chemical, physical, and other data were collected from the NEW HORIZON from November 12, 1980 to November 12, 1980. Data were collected using meteorological sensors, Secchi disk, and bottle casts. Data were submitted by Scripps Institution of Oceanography (SIO) as part of the California Cooperative Fisheries Investigation (CALCOFI) project.

Chemical, physical, and other data were collected from NOAA Ship DAVID STARR JORDAN, ROGER REVELLE, and NEW HORIZON from August 7, 1996 to April 19, 1997. Data were collected using bottle casts in the Pacific Ocean. Data were submitted by Scripps Institution of Oceanography (SIO) as part of the California Cooperative Fisheries Investigation (CALCOFI) project.
