The
IODE workshop on quality control (QC) of chemical oceanographic data collections
was held at the IOC Project Office for IODE in Oostende, Belgium between 8 and
11 February 2010. The meeting, proposed and organized by the IODE Group of
Experts on Biological and Chemical Data Management and Exchange Practices
(GE-BICH), welcomed 19 experts in chemical data management as well as data
producers and users from 13 countries. The objective of the workshop was to
evaluate existing procedures and define a minimum set of QC tests and criteria
for dissolved inorganic nutrients (phosphate, silicate, nitrate+nitrite,
nitrate, nitrite, and ammonium) and dissolved oxygen in seawater. The meeting
produced several outcomes. First, the meeting identified two proposals to be
submitted to the IODE/JCOMM Ocean Data Standards process (1) a quality control
flag scheme based on quantifiable and subjective tests; and (2) at a later
stage and following consultation with the wider community, a scaled
nomenclature for data processing levels for data held in data centers. The
meeting also issued a number of recommendations which will be taken forward in
post-workshop activities in consultation and in interaction with the wider
international community. These included: (1) metadata terminology for reporting
measured variables and their units of measure as well as (2) a work plan to
recommend a minimum set of numerically defined QC tests that could be adjusted
to reflect broad regional to basin scales conditions. These guidelines and
recommendations will be assembled on the GE-BICH wiki for peer-review before being
published as a technical white paper or guideline document. The report is available through http://www.iode.org/wr228
