1. WP15: Data management 1. Observations: Field Work (sediment cores & water column; sections, time series stations, moorings, etc.) Mesocosm Experiments Laboratory Experiments Challenges: Moderate data volume but very large variety of data types, parameters and formats. Many PIs involved.

2. WP15: Data management 2. Model Output: Results from regional and global EPOCA models Challenges: Very large data volume but limited variety of parameters and data formats (netCDF).

3. Implementation 1.Observations: WDC- Mare (S. Pesant, A.-M. Nisumaa) Quality control by individual PIs Importance of metadata 2.Model Output: Catalogue of model runs including PI contact information Core experiments available through online system (J. Orr, L. Bopp, N.N.)

8. Data sharing policy To be established by M3 Objective: Promote open access of observational data and model results to EPOCA PIs while protecting the intellectual property rights of the data producers. Timeline: Delivery to EPOCA database 3 months after data creation. Proprietory rights period of 2 years. Data usage by EPOCA and external partners with permission of originator strongly encouraged to maximize scientific output. Data publicly available 2 years after data creation.

9. In case of conflicts: Panel for protection, dissemination, and exploitation of knowledge. It will monitor and give recommendations to the EB on priorities aimed at encouraging and promoting data and information exchange in a timely and efficient manner. It will also propose a data policy with binding rules for all project partners and oversee the data management. Members Peter Burkill Reiner Schlitzer (Chair) Markus Weinbauer
