Physical, chemical, biological, meteorological, and other data were collected from bottle casts, CTD casts, and divers from FIXED PLATFORMS. Data were collected by Western Washington University (WWU) from 06 February 1989 to 12 March 1998. Physical parameters include water temperature, pH, dissolved oxygen, turbidity, and salinity. Nutrients parameters include concentrations of ammonia, nitrate, phosphate, phaeopigment, and C02. Meteorological parameters include wind speed, rainfall, and cloud cover. Skin diver data include sighting of juvenile rockfish, collection of sea cucumbers, and collection of green urchins.

Physical, nutrients, and other data were collected from CTD and bottle casts from the North Pacific Ocean from 19 February 1991 to 31 December 2000. Parameters include water depth, temperature, and salinity. Parameters also include concentrations of chlorophyll, silicate, phosphate, nitrate, and nitrite. Minkley, B.G., and F.A. Whitney. 2001. Summary of Hydrographic/CTD Observations made along Line P and at Station P: 1991-1999. Canadian Data Report of Hydrography and Ocean Sciences No. 156: 40 p. A summary of 30 missions which sampled part or all of Line P between January 1991 and December 1999 is provided. Plots of mission tracks show the areas surveyed, participants are listed, and types of sampling, inventoried. A review of sampling equipment outlines the conversion from 1.7 litre Niskin bottles mounted on 5/32-inch wire hydro wire to CTD/Rosette cast sampling using 10 litre bottles. Missions which supported programs for World Ocean Circulation Experiment and Joint Global Ocean Flux Studies are listed. A previous report contained observations for the period January 1980 to December 1989 and is found in Canadian Data Report of Hydrography and Ocean Sciences No.136, by Tabata and Brown.

Physical, nutrients, and other data were collected from CTD, MBT, XBT, and bottle casts from the Indian Ocean. Data were collected from 01 January 1976 to 31 December 1996. XBT parameters include temperature profiles. Bottle and CTD parameters include temperature, salinity, and concentrations of oxygen, silicate, nitrate, nitrite, ammonia, and alkalinity.

Chemical, physical, and other data were collected from bottle and CTD casts in the Indian from the MELVILLE from 04 December 1977 to 24 April 1978. Data were collected by the Scripps Institution of Oceanography (SIO) as part of the International Decade of Ocean Exploration / Geochemical Ocean Study (IDOE/GEOSECS). Physical parameters include depth, temperature, salinity, pH, and pressure. Chemical parameters include concentrations of carbon dioxide, oxygen, phosphate, nitrate, nitrite, and silicate.
