ON THE INTERNATIONAL CONFERENCE ON TECHNICAL ASPECTS OF MARITIME
BOUNDARY DELINEATION AND DELIMITATION, INCLUDING UNCLOS ARTICLE 76
ISSUES (ABLOS), MONACE, 9-10 SEPTEMBER, 1999.
attendees from twenty-nine countries were present at the Conference.
In addition the International Hydrographic Bureau (IHB) personnel,
members of the UN Commission on the Outer Limits of the Continental
Shelf and the UN Division of Ocean Affairs and Law of the Sea
participated. The sessions and papers were organised by the Conference
Committee chaired by P. Vaniçek, chairman of ABLOS, and the
Conference Proceedings, containing the 26 paper presented, will be
produced by the IHB.
The Conference was
divided into four sessions over a span of two days. In the first
session, Issues concerning the UN Commission on the Limits of the
Continental Shelf, convened by G. Carrera, topics related to the
approach of the UN CLCS to submissions made by coastal states were
considered in contributions presented by members of the Commission.
The following papers were delivered: CROKER, Peter, CLCS Member
(Ireland), The mandate and work of the Commission on the Limits of
the Continental Shelf.HINZ, Karl, CLCS Member (Germany), A
review of continental margins of the world. LAMONT Iain, CLCS
Member (New Zealand), Formulating the New Zealand Continental Shelf

The second session,
Geodetic issues, with emphasis on errors in maritime boundaries and
how to reduce them, convened by B.G. Harsson, dealt with
specifically geodetic problems of delineation and delimitation of
maritime boundaries. The following papers were delivered: CARRERA,

location of the outer limits of the extended continental shelf".

Netherlands) "The determination of boundaries at sea between
Belgium and The Netherlands".
The third session, Tools needed for boundary
delimitations, convened by R. Macnab, dealt specifically with
hardware and software that would be necessary to obtain the data to
substantiate a continental shelf claim. The following papers were
delivered: PALMER, Hal, Lorin Pruett, and Kurt Christensen, (USA),
"GIS applications to maritime limit and boundary delimitation.

In the last session, Other issues and case
studies (not necessarily related to Article 76), convened by C.

discussion. The following papers were delivered: MONAHAN, David and
David Wells, (Canada) Achievable uncertainties in the depiction of

The Conference, staged in the beautiful new
offices of IHB, was considered a great success and a possibility that
a bi-annual ABLOS-sponsored conference could become a regular
international venture in Monaco was discussed. It was the first time
that the IHB offices have been utilised for a conference of this
format and it was evident that the facilities would not be adequate to
support a conference wit a larger number of participants. It is
anticipated that the assistance of the Principality of Monaco will
have to be sought if this was to become a regular venture.
