Joint Global Ocean Flux Study (JGOFS) measurements taken by Germany, The Netherlands, and the United Kingdom from 1991.

The Joint Global Ocean Flux Study (JGOFS) is an international and multi-disciplinary study with a primary objective of understanding global oceanic carbon and nutrient cycles. The National Science Foundation has funded two time-series stations as part of JGOFS, one in Hawaii (HOTS) and a second in Bermuda, the Bermuda Atlantic Time-series study (BATS). BATS was funded under NSF Grant # OCE-8801089. This data set is comprised of bottle pigment data (chlorophylls a and b, peridinin, fucoxanthin, lutein, carotene, and others) and nutrient data (total carbon dioxide, nitrate+nitrite, silicate, and phosphate in μmol/kg) collected as part of BATS Year One (Cruises 1-12, October 1988-September 1989) and BATS Year Two (Cruises 13-24, October 1989-September 1990. The cruises were conducted using ship WEATHERBIRD. CTD and particulate organic carbon and nitrogen (in μg/kg) and bacteria counts were also provided with these data. Data were collected in the immediate area of the nominal station location at 31 degrees 50'N, 64 degrees 10'W. The core measurements require 5 casts per cruise, utilizing a SeaBird CTD mounted on a General Oceanics rosette equipped with 121 #12 Niskin bottles. Originators data was submitted by Mr. George Heimerdinger, Woods Hole Oceanographic Institution, Woods Hole, MA. The data have been processed and are available in C100 Ocean Station Data as well as F022-CTD Hi Resolution data format of NODC.

This dataset includes physical, chemical, and biological data, including plankton abundance, biomass, biovolume, counts, population estimates, primary production, carotenoids, phaeopigments, fatty acids, chlorophylls, aggregates and particulate matter, "marine snow", thymidine and leucine uptake, nitrate and saturated ammonium uptake rates, oxygen production, irradiance, Lu683, PAR, Thorium-234 activity, water temperature, currents and salinity, and other data. The U.S. Joint Global Ocean Flux Study (JGOFS) Equatorial Pacific (EqPac) process study was conducted along 140°W during the calendar year 1992. Four process cruises took place, with a fifth benthic cruise and sediment trap legs adding to the overall study.

Biological, physical, nutrients, sediment, and other data were collected using sediment sampler-grab, bottle and CTD casts in the Arabian Sea, North/South Pacific Ocean, and North Atlantic Ocean from 08 January 1995 to 08 April 1998. Data were submitted by Woods Hole Oceanographic Institution as part of the Joint Global Ocean Flux Study (JGOFS) project. Biological data include detailed information on phytoplankton and zooplankton. Nutrients data includes nitrate, nitrite, phosphate, and silicate. The U.S. Joint Global Ocean Flux Study (U.S. JGOFS), conceived in 1984 and organized as a major ocean research program shortly thereafter, has conducted field and modeling investigations of the global ocean carbon cycle and the processes that regulate it for a decade and a half. It has brought together biological, chemical, physical and geological oceanographers and modelers in a multidisciplinary investigation of the pools and fluxes of carbon and associated biogenic elements in the ocean. U.S. JGOFS is a component of the international Joint Global Ocean Flux Study (JGOFS), launched in 1987 under the aegis of the Scientific Committee on Oceanic Research (SCOR). Designated a core project of the International Geosphere-Biosphere Programme (IGBP) two years later, JGOFS has involved scientists from more than 30 countries in field and modeling studies. Its research program included national and international process studies conducted in many ocean basins, time-series programs and a global survey of carbon dioxide (CO2) in the ocean. The U.S. JGOFS research program comprised four basin-scale process studies, two long-term time-series programs, participation in a global survey of (CO2) and a synthesis and modeling project. This CD-ROM contains the data acquired during the four U.S. JGOFS process studies, conducted in the North Atlantic, the equatorial Pacific, the Arabian Sea and the Southern Ocean. Data from other components of U.S. JGOFS will be published in future volumes.

The OZGOFS research project was a multidisciplinary project comprising 3 research cruises on the R.V. Franklin in October 1990, July 1992 and November 1993. The area of operations was between 2ºS and 6ºN along 147ºE and between 10ºS and 10ºN along 155ºE. The ADCP data is presented in 8 meter bins at 20 minute averages along the major transects. CTD data for each cruise is presented as individual stations. The first 12 lines in each profile are header information: ship, date, start time, bottom time, finish time (UTC), cruise number, start position, bottom position, and finish position (as dd mm.ss), maximum depth and ocean depth. The CTD data, plus density (as sigma-t), fluorescence and PAR is presented in 2 meter bins. Where no information is presented under a header (e.g. PAR, fluorescence) the sensor was not present on the CTD during the cast. Fluorescence profiles from a SeaTech fluorometer mounted on the CTD converted to chlorophyll-a profiles using a regression of fluorescence burst data (taken when a niskin bottle is closed) and the extracted chlorophyll sample at that depth. The fluorescence profiles were calibrated using chlorophyll-a evaluated using the trichromatic equations for FR 9008, but HPLC chlorophyll-a on FR 9205. The regressions are given in the metafiles. Where possible, the extracted chlorophyll-a data have been depth-matched and included on the data files. The parameters sampled from niskin bottles (salinity, nutrients, chlorophyll and pigments, bacteria and cyanobacteria, lipids, nutrients, primary production) use the same template, derived from the hydrochemistry sampling sheets, but are in separate directories. The general form is for each station to be listed, along with a counter, time and date of sampling, station position, niskin number and position on the rosette (when supplied), and then the data. Radionuclide data was taken at one site on FR 9205, and three on FR 9308, and consisted of measurements of dissolved and particulate 226Ra, 210Pb, and 210Po. Underway data are found in the Surface CO2 directories. Surface pCO2 data measured using an equilibrator are from FR 9205 only, and contain date, time, position, surface temperature and salinity, atmospheric pressure and fCO2 data. There are estimates of pCO2 from pH studies in surface waters from FR 9008, FR 9205, and FR 9308. These files contain Files in the Underway Data directory contain date, time, position, surface temperature, salinity, fluorescence (in uncalibrated Turner units), pH and pCO2 data. The free-floating sediment trap data, from FR 9308 only, consists of HPLC pigments and pigment flux estimates, and flux estimates for dry weight, carbonate, organic matter, and total carbon, nitrogen and phosphorus fluxes. Zooplankton was sampled on FR 9205 and FR 9308 using a 200 micron mesh aperture free-fall plankton net. Settled volumes and dominant taxa only were recorded.

CTD and Transmissometer data from JGOFS Programs: Equatorial Pacific (EqPac), Antarctic Polar Front Zone (APFZ), North Atlantic Bloom Experiment (NABE), Arabian Sea cruise, the Hawaii Oceanographic Time-Series (HOT), and the Bermuda Atlantic Time Series (BATS). Data collected during 1990s. Data were post-processed in Texas A & M University and submitted to JGOFS archives.

This dataset includes carbon dioxide, temperature, salinity, and other variables collected via surface underway survey from Volunteer Observing Ship S. A. AGULHAS in the South Atlantic Ocean and the Southern Oceans (> 60 degrees South) from 2008-09-04 to 2010-05-20, on the GOUGH, MARION, and SANAE Expeditions. This cruise was divided into 6 legs 1: Cape Town - SANAE; 2: Operations around SANAE; 3: SANAE - South Georgia; 4: South Georgia - SANAE 5: Operations around SANAE; 6: SANAE - Cape Town.

This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Investigator in the South Pacific Ocean, Tasman Sea in 2025. These data include partial pressure (or fugacity) of carbon dioxide (pCO2) in water and air, sea surface temperature, sea surface salinity, barometric pressure, wind direction and wind speed. The instruments used to collect these data include barometric pressure sensor and carbon dioxide (CO2) gas analyzer.
