U.S. JGOFS Sampling and Analytical Protocols
The Joint Global Ocean Flux Study relies on a variety of analytical techniques and measurement strategies to characterize the biogeochemical state of the ocean. At the time of the North Atlantic Bloom Experiment (NABE), in which just a few nations and a relatively small number of laboratories contributed most of the measurements, there was a general understanding that experience, capability and personal preferences about particular methods varied significantly within the program. An attempt to reach consensus on the best analytical techniques to use is documented in JGOFS Report 6, "Core Measurement Protocols: Reports of the Core Measurement Working Groups, 1990". Over time, as JGOFS has grown and diversified, the need for standardization has intensified.
In 1993, the U.S. JGOFS program compiled a summary of sampling and analytical protocols used during the Equatorial Pacific Project (EqPac). U.S. Joint Global Ocean Flux Study, Equatorial Pacific Protocols, edited by Susan Kadar, Margaret Leinen and James Murray, 1993. (http://usjgofs.whoi.edu/eqpac-docs/proto.html)
In 1994, the revised version of JGOFS Report 6 was released as Protocols for the Joint Global Ocean Flux Study (JGOFS) Core Measurements, 1994 UNESCO, and is available online as JGOFS Report No. 19. (1996)   (http://ijgofs.whoi.edu/Publications/Report_Series/JGOFS_19.pdf).
In response to their own needs, the two JGOFS Time Series sites (Bermuda and Hawaii) have each produced their own methods manuals:
Joint Global Ocean Flux Study, Bermuda Atlantic Time-Series Study,
BATS Method Manual, version 4, April 1997.
Hawaii Ocean Time-Series Program Field and Laboratory Protocols, September 1990. ON LINE ONLY (http://hahana.soest.hawaii.edu/hot/protocols/chapi.html).
The CO2 component of the JGOFS program also found the need to compile a methods manual: Handbook of Methods for the Analysis of the Various Parameters of the Carbon Dioxide System in Sea Water, Version 2, edited by Andrew Dickson and Catherine Goyet, September 1994, U.S. Department of Energy. (http://www-mpl.ucsd.edu/people/adickson/CO2_QC/Level1/Contents.html) Although a key component of the JGOFS science initiative, a major portion of the measurement effort was conducted during the World Ocean Circulation Experiment (WOCE).
The U.S. JGOFS Data Management program required that each submitted dataset be accompanied with sampling and analytical methodology. In many cases, the appropriate section from the above manuals have been referenced. However, over time, the methods referenced are those that appear in refereed journal articles.
