CARBOOCEAN Data management and SOCAT Benjamin Pfeil, Are Olsen, Jeremy Malzcyk, Steve Hanhin, Alex Kozyr and many others Partner 16 WDC-MARE Partner 19 Ifremer-Sismer SSC CDIAC Partner 1 UIB 4 th annual CARBOOCEAN meeting, Dourdon, France

What has been happening in 2008? Business as usual (new data from around 200 cruises were archived) SOCAT dataset has been growing and is ready for secondary QC CARINA is finished Collaboration with other projects EPOCA, SOPRAN, etc

SOCAT in numbers changes since last year December 2007December 2008 Number of cruises, time series station, buoys< 1300> 2100 Total amount of measurements (eg SST, SSS)5.5 million10 million Amount of CO 2 measurements< 4.5 million> 7 million Amount of cruises from CARBOOCEAN< 50 (4 %)> 300 (14.5 %) Amount of cruises from CARBOOCEAN PIs< 250 (20 %)> 500 (24 %) North America EuropeJapanothers Origin of data44 %36 %18 %< 2 %

Many CARBOOCEAN PIs agreed to include their data within SOCAT

How will data be made available for secondary QC and afterwards to the community?

Live Access Server and Subversion for SOCAT Jeremy Malczyk and Steve Hankin (NOAA/PMEL)

Live Access Server (LAS) A web server for visualizing gridded and in-situ data Multiple configurable data sources (netCDF, databases, etc) Highly configurable and extendable output Wide range of data products for interpolation, comparison, visualization, and analysis Updated version to the needs of SOCAT will soon be available

A centralized system for sharing information Commonly used to maintain a code base with a complete version history. Very powerful to manage conflicting changes from multiple users Will show differences between versions Will be able to retrieve older versions if mistakes are made What is Subversion (SVN)?

SOCAT Workflow Cruise files (text MatLab tables) and QC documents are committed to the Subversion Repository LAS provides visualization, analysis, and data retrieval tools to help scientists interact with the repository QC feedback is committed to the repository in QC documents Revised data files may be committed as well

Workflow within SOCAT SVN repository Cruise files QC Documents Scientists QC the data QC documents Revised QC documents (data quality flags and notes) Revised data files LAS

Why are we using Subversion? What are the benefits? Data can never be lost or overwritten Management responsibility is removed from a single entity (the repository can be mirrored or moved with its revision history intact) A complete revision history (of both the QC and data) is maintained for repeatability and documentation purposes Changes by individual users are tracked The data is accessible at any time

CARBOOCEAN SOCAT underway database But there is a large overlap Within SOCAT is just CARBOOCEAN data included if the PI agreed Small reminder from last year’s presentation ≠

Combined underway database SOCAT + Will be or is public data Non public data = CARBOOCEAN data

What happens in the future when CARBOOCEAN underway data will be published? SOCAT version x CARBOOCEAN Underway DB ∧

Already publically available CARBOOCEAN data > 50 cruises Available at the data portal and at CDIAC with detailed metadata If your data gets published please inform me

Thank you!
