National Oceanographic Data Committee (NODC)
• Committee – no centre
• Based on Memorandum of Understanding (MoU) (1997-)
• Fully distributed structure
Currently 8 Partners:
- Rijkswaterstaat Water Dienst (RWS-WD)
- Royal Netherlands Institute for Sea Research (NIOZ) (Academic community)
- TNO – Bouw en Ondergrond (TNO – B & O)
- Hydrographic Service (KM-HYD)
- Rijkswaterstaat Data en Informatie Dienst (RWS-DID)
- Centre for Estuarine and Marine Ecology (NIOO-CEME)
- Imares
- Deltares
1997-2008: Royal Netherlands Meteorological Institute (KNMI)
- Advisor: Marine Information Services (MARIS)SDN Annual Meeting 20090326

National Oceanographic Data Committee (NODC)
• Very interesting mix of government agencies (3), research institutes (2)
and privatized, former government agencies (3)
• Government agencies have specific tasks, limited to territory and EEZ of the Kingdom of The Netherlands, Netherlands Antilles and Aruba.
• Other NODC Partners may operate all over the world
• Data from all disciplines: Coastal research, bathymetry, geology, biology, ecology, physical oceanography, marine meteorology, etc, etc.
• Many different data types

The NL-NODC is the national platform for oceano-graphic data management
• Objectives:
1) to further data management and the delivery of quality data to a broad user group
2) to lower thresholds and barriers (organisational, technical, financial)
for data exchange
• National Data Policy
• Participation in international initiatives (IODE, ICES, EU-projects like Sea-Search, SeaDataNet, EMODNET projects, etc.)

Situation of data exchange within NL-NODC a couple of years ago:
Online accessibility and availability of data
• Waterbase (RIKZ)• CODIS (NIOZ)• KODAC (KNMI)• Watermarkt (RIKZ + many other partner institutes)• HYDRA (KNMI)• COREBASE (NIOZ)• DINO (TNO- B&O)• Getij.nl (RIKZ)• Waterstat.nl (RIKZ)• many more …..
- user had no overview of data availability
- user had to do all format conversions and syntheses

NODC: Organisational structure for data exchange:
• MoU
• Data Policy
No technical infrastructure for data exchange:
• Different RDBMS
• Different formats
• Some databases online, others are not

National infrastructure for access to oceanographic and marine data and information:
NODC-i
Objectives of the project:
• central index of all data in the partner databases
• transparent access via Internet to the partner databases (fully distributed system)
Project:
• February 2005 – December 2008 ( 2 phases)
• 1 M Euro (500k from Bsik – Ruimte voor Geo-Informatie (RGI))

SeaDataNet to the rescue:
SeaDataNet is developing techniques, standards and formats,
which can be applied within NODC-i and vice versa
SeaDataNet ensures a high level of standardization
SeaDataNet is implementing on an European level, what NODC-i has implemented on a national level
NL-NODC is an ideal test bed for SeaDataNet
