The WP6 objective is to design and implement the MaRINET 2 e-infrastructure. Within WP6, two key issues are addressed: “Data preservation” and “Data sharing within a VRE” (Virtual Research Environment) leading to these objectives:

• Data preservation: a common policy compliant with international standards (RDA – Research Data Alliance) and European standards for Marine data (SeaDataNet)
• Data access and service : a Virtual Research Environment (VRE) workplace based on common national and European e-infrastructures (such as SeaDataCloud)

The MaRINET 2 e-infrastructure supports these via the following actions:

• Collection and storage of MaRINET 2 experiment descriptions and results to secure their interoperability and long-term preservation
• Discovery, visualization and downloading of MaRINET2 experiment descriptions and results/datasets (previous and ongoing) to support R&D and inform device design
• Provide secure and controlled access to datasets and virtual tools for joint research activities

This document describes and explains how MaRINET2 WP6 organises the long-term data preservation, and data discovery, access and use.
