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

• mutually agreed with the coastal state
• complementary to existing regional data centres
• confidentiality needs
• Part XIII of the Convention
• use of existing data management mechanisms
• Intergovernmental Oceanographic Commission
• International Hydrographic Organisation
• coastal states, in particular developing
  countries and SIDS

The Start - Arendal Workshop
Representatives from
Mozambique Angola Seychelles Senegal Madagascar
Cape Verde Philippines Sri Lanka
Conclusion The most efficient way to make use of
UNEPs 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

• Get hold of Metadata
• Include easily available digital data at same
  time as collecting Metadata
• Collect non-digital and other less available data
  on request from states
• Use filters/conversion programs to import,
  process and output datasets in various formats
• Ensure all software modules access the same
  primary database
• Establish security and access control

Status

• Launched the service January 2005
• Currently improving technical solutions
• New data sources
• Contacting major Data Owners GEODAS, BGR
  Japan, Ifremer, Southampton, ODP/DSDP
• Data Links on internet present and expanding

Status - Continued

• Scanning of relevant areas completed
• Using scanning results to populate the One Stop
  Data Shop
• Will gather residual data on demand
• Work lab for customer support
• Demand driven, need more customers

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 OSDSs 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

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
