World Data Center for Marine Environmental
SciencesWDC-MARE
established in 2001
Biogeochemistry, Circulation, and Life of Present
and Past Oceans The WDC is aimed at collecting,
scrutinizing, and disseminating data related to
Global Change in the fields of environmental
oceanography, marine geology, paleoceanography,
and marine biology. WDC-MARE focuses on
georeferenced data using the information system
PANGAEA.

Recommendations from The Colour of Ocean Data
EU-Symposium on Oceanographic Data and
Information Management, Brussels, 2002

• Close cooperation between stakeholders and data
  center
• Peer review of datasets becoming part of the
  curriculum of marine scientists
• Comprehensive portals that do not lead to
  metadata nonsense, but directly to data and
  information
