Mandate – UN General Assembly 2002
“Calls upon the United Nations Environment Programme, working within the Global Resource Information Database (GRID) system for data and information management, to
expand on a voluntary basis the capacity of existing GRID centres to store and handle research data from the outer continental margin, on a basis to be mutually agreed with the coastal State, and complementary to existing regional
data centres, giving due regard to confidentiality needs and in accordance with Part XIII of the Convention, and making use of existing data management mechanisms
under the Intergovernmental Oceanographic Commission and the International Hydrographic Organisation, with a
view to serving the needs of coastal States, and in particular developing countries and small island developing
States, in their compliance with article 76 of the Convention;”

The Start - Arendal Workshop
Representatives from:
Mozambique Angola Seychelles SenegalMadagascarCape Verde Philippines Sri Lanka
ConclusionThe most efficient way to make use of UNEP’s GRID system is to establish
a centre for the management of marine geophysical, bathymetric and geological research data that will be
hosted in one of its centres. Workshop participants identified and
need for such a "one stop data
shop".

Simplified Work Flow
1. Get hold of Metadata2. Include easily available digital data at same
time as collecting Metadata3. Collect non-digital and other less available data
on request from states4. Use filters/conversion programs to import,
process and output datasets in various formats5. Ensure all software modules access the same
primary database6. Establish security and access control
One Stop Data Shop
Status
Launched the service January 2005 Currently improving technical solutions New data sources Contacting major “Data Owners”
GEODAS, BGR; Japan, Ifremer, Southampton, ODP/DSDP…

Typical Data Types
Data Coast line State borders Base lines ETOPO2 GEBCO World sediment thickness map Well data, electrical logs Aeromagnetic data Satellite gravity Bathymetry, two way travel time Corrected bathymetry Side scan sonar Multi beam bathymetry Magnetics total field Magnetics residual field Observed gravity Free air gravity anomaly Single channel seismic reflection CDP seismic reflection

Area Generator
Generate a ”project” anywhere in the world in chosen projection and datum in a few minutes.
The ”project” can be converted by the ”OSDS” filters to the desired format for import into chosen tool.
Data completeness of the ”project” will depend on the ”OSDS’s” ability to get access to and process relevant data.

Seismic Data
CDP Sismic data (digital) relatively straight forward Challenge to use non - digital seismic data more
effectively. Investigating solutions:– Reconstruction of seismic traces, result is SEG-Y data– Interpreting scanned seismic images directly
• Status: Both work processes possible, choose most practical and cost efficient
• Of course, there will always be coloured pencils
One Stop Data Shop
Why develop the One Stop Data Shop?
Cost effective way ”to store and handle research data”
Acts as one port of entry to access data Each state does not have to start from scratch UN Umbrella ”Data owners” know who they are dealing with Effective way to build and use expertise Effective way to transfer capacity to states
One Stop Data Shop
