Geo-Seas populates and provides a common catalogue of available data sets, such as samples, cores and seismic survey data, managed by national geological surveys and research institutes in Europe.
To provide a detailed inventory of data sets Geo-Seas has adopted and adapted the Common Data Index (CDI) Data Discovery and Access service of SeaDataNet. This provides an ISO19115-based index to data on individual samples, cores and geophysical measurements and a unique interface to access these data sets online. The vast majority of Geo-Seas data centres is now connected and populates the CDI service with metadata for their data sets.
Moreover Geo-Seas contributes to the following European metadatabases, that are coordinated by the National Oceanographic Data Centres (NODCs) of SeaDataNet:
- European Directory of Marine Environmental Data sets – EDMED
- European Directory of Marine Environmental Research Projects – EDMERP
- European Directory of Marine Organisations – EDMO
- Cruise Summary Reports – CSR
These present a matrix of data-related activities. Visit these metadatabases at the SeaDataNet portal
Existing metadatabases of samples, cores and seismic survey data sets
Previously partners have developed the EU-SEASED metadata service in the framework of the EU-funded projects EuroCore, EUMarsin and EuroSeismics (1998 – 2004). This service provided an inventory of seabed samples, cores, and seismic surveys, containing information on more than 300.000 samples and cores, and more than 1.000.000 line kilometres of seismic survey data, mostly for European seas, but also for the world oceans.
Geo-Seas is upgrading and replacing the EU-SEASED service and its inventories, and is extending the functionality considerably by adding direct online data access.
Furthermore partners had developed the SEISCANEX infrastructure in the framework of the EU-projects SEISCAN and SEISCANEX (1997 – 2004). Old seismic reflection data from deteriorating paper records have been rescued by scanning the records. Over 14.000 TIFF-format images, representing 2.000.000 line kilometres of seismic survey data, were generated, and archived in databases at partners in the UK and France. The metadata is based on the FGDC (1994) standard, and images are viewable as thumbnails on a web portal.
Geo-Seas is upgrading the SEISCANEX inventory and access to data, and is integrating the SEISCANEX data centres in the Geo-Seas infrastructure.
This implicates in practice that Geo-Seas is taking over and phasing out the SEISCANEX and EU-SEASED portals.
