2. MaNIDA– Enabling Data-Intensive Marine Science • Global Change • Assessing, understanding, and predicting environmental changes • Human environmental impact • Hazards • Risk analysis and support for disaster management • Understanding environmental factors affecting human health • Resources • Sustainable ecosystem management • Energy from the ocean

3. Status of Marine Science Data in Germany • Extremely wide range of data sources • Ship-based instruments • Instruments in water column and at seafloor • Air- and space-borne instruments • Sensor networks (increasingly in the deep ocean) • “snapshots“ (individual projects) andlong-term monitoring • storedin different datacenters(e.g. AWI/PANGAEA, BSH/DOD, HZG/COSYNA) •  Requirement : Data-intensive researchthroughcoherentdataportalwithcommonaccessstrategy

4. “Where is the data” – i.e.: First step is better discoverability; but more easy to foresee: qualityissues, complex selection, aggregation, … • Finding common semantics and syntax on • parameter names - “chlorophyll”, taxa • quality flags and processing levels – raw, primary, gridded … (“levels” borrowed from remote sensing) • Finding common approaches to • pre-ingest workflow, responsibilities and procedures - who is responsible for switching sensors on/of; who preserves diplomatic documents, calibration sheets, … QA/QC • openness – who has to make data available when • MaNIDA is a PROCESS, forcing all these question to be address - finally
