Article 76 is short but complex

We fully understand that delineation of the extended continental shelf

is a complex scientific and legal exercise that requires expertise in

the fields of geoscience, law and IT.

No single government body could handle this task

Decided to set up the Extended Continental Shelf Sub-committee

We also seek the experience of international consultants when

necessary

Team work

Data Management

  • Currently setting up a computerised meta-database

  • - all participating bodies have submitted table structures

  • - brainstorming to come up with a data model

  • The Tech Comm. is helping to finalise a national data policy

  • Quality Assurance procedures to be implemented by all parties

  • The MBDP database will serve as a pilot study for creation of

  • Seychelles Geoscience Data Centre (SGDC)

  • Data will be stored at respective organisation until SGDC ready

Difficulties & Limitations

  • Limited financial resources (competing with other National priorities)

  • Limited human resources (experts not 100% committed to

  • project)

  • Seychelles is remotely located (access to workshops &

  • conferences)

  • Data hunting can be tedious
