DEAL data


Archiving marine data with BGS

• Data must be supplied in a recognised exchange format

• Be in a format appropriate for the data type

• Supplied on a modern type of media e.g. Exabyte tape)

• Older media is not acceptable e.g 9 track media

Objective of Geoseas

“ build and deploy a unified marine geoscientific data infrastructure within Europe”


Geo-Seas

• Build and deploy a unified marine geoscientific data infrastructure within Europe

• Improve locating, accessing and delivering marine geological and geophysical data

• Interoperable with other data e.g. oceanographic data

• Provide middleware to locate, retrieve and use primary data in multidisciplinary combinations.


Objectives of GeoSeas• Expand SeaDataNet infrastructure by including the

network of national geological surveys and selected geological research institutes

• Publish and maintain a common catalogue and index of available data, data products and services managed by European geological surveys and research institutes

• Harmonise quality standards and exchange formats to facilitate access and delivery of this data to user communities.

• Provide federated marine geological and geophysical data sets to the user community using middleware to access and deliver data via the internet
