1. EMODnet Chemistry 4° Steering Committee, Amsterdam QC inventory Matteo Vinci and Alessandra Giorgetti – OGS, Italy

2. QC inventory intro...why...when..who... The QC inventory for EMODnet Chemistry 2 Lot started to collect the best practices performed by the different participant institutes. The aim of this collection was to make an inventory of QC best practices and start a communication to homogenize/ improve this work where possible. The QC inventory templates has been sent in two times: the 21/05/2014 to a first small set of partners (Regional Leaders and/or Members of Steering Committee) Then the template already filled by OGS and SMHI has been sent (as example) the 02/10/2014 to the whole partnership

12. Conclusion/Proposal... Further analysis on these results? (e.g. Metadata/Data checks, Kind of check per parameter...a lot of information/time consuming...) Share ranges used Further useful surveys (beside this and the one done by ISPRA)? IODE suggested to submit the results of our inventory in their repository of documentation regarding best practices in data management  a beta version of the repository can be seen on: http://www.oceandatapractices.org
