Abstract:
The SOCAT Pacific Regional Group met at the National Institute for Environmental Studies in Tsukuba, Japan from 18-20 March 2009. The workshop was co-chaired by Yukihiro Nojiri and Steve Hankin and attended by twenty scientists from seven different countries. The Pacific regional group met with the developers of the Live-Access Server tools to learn how LAS can be used in the QC effort for SOCAT. The participants installed the tools and software on their computers, downloaded the data files for their regions, set up the shared QC environment, and worked through several exercises to demonstrate the system. The groups began working through the data sets for their region (flagging, determining which 2nd level QC tests may be applied, testing those, etc.)
BACKGROUND
At the “Surface Ocean CO2 Variability and Vulnerability” (SOCOVV) workshop in April 2007, co-sponsored by IOCCP, SOLAS, IMBER, and the Global Carbon Project, participants agreed to establish a global surface CO2 data set that would bring together, in a common format, all publicly available surface fCO2 data for the surface oceans. This activity has been requested by many international groups for many years, and has now become a priority activity for the marine carbon community. This data set will serve as a foundation upon which the community will continue to build in the future, based on agreed data and metadata formats and standard 1st-level quality-control procedures, building on earlier agreements established at the 2004 Tsukuba workshop on “Ocean Surface pCO2 Data Integration and Database Development”. This activity also supports the SOLAS and IMBER science plans and joint carbon implementation plan.
INTRODUCTION TO THE WORKSHOP
The SOCAT Pacific Regional Group met at the National Institute for Environmental Studies in Tsukuba, Japan from 18-20 March 2009. The workshop was co-chaired by Yukihiro Nojiri and Steve Hankin and attended by twenty scientists from seven different countries (Appendix 1) At the SOCAT-II technical meeting in Paris (June 2008), participants agreed that the next steps in the development of the SOCAT data set were to have the regional groups meet to identify missing data sets, review the quality of the data, determine which 2nd level quality-control checks may be performed, and begin testing them.
The Pacific regional group met with the developers of the Live-Access Server tools to learn how LAS can be used in the QC effort for SOCAT. The participants installed the tools and software on their computers, downloaded the data files for their regions, set up the shared QC environment, and worked through several exercises to demonstrate the system.
MEETING SUMMARY
At the end of the meeting, suggestions were solicited from the group on ways to improve the LAS system and the underlying database. Among the most important agreements was the consensus realization that level 1 QC issues remained to be corrected in the database. Benjamin agreed to issue a new version of the collection (v1.3) that would address the level 1 QC problems identified at the Tsukuba meeting. Steve and Jeremy agreed to add capabilities in the LAS system to facilitate a community process on rooting out level 1 QC problems, as well. Many of the suggestions were of a technical nature regarding enhancements to LAS.
