Today western nations consume annually only a small percentage of
their resources from the sea, despite the proclamation of Exclusive
Economic Zones (EEZ) by many. In contrast, most Pacific Basin
Countries obtain more than a quarter of their annual needs from the
ocean. Determination of greater rewards from the development of
marine resources is markedly inhibited by the limited technical
abilities available to locate and assess them. Knowledge of
Exclusive Economic Zone resources is schematic and generalised, and
a detailed understanding of the geology and processes relating to
the economic use of the seafloor is both fragmentary and very
basic. Technology for mapping the mineral resources of continental
shelves and ocean areas, except in active offshore hydrocarbon
provinces, has been largely developed in pursuit of scientific
objectives and competence to rapidly appraise economic potential is
limited. Similarly, the capability to characterise and evaluate the
other resources of the seas is rudimentary. The development of
ocean resources will become increasingly urgent as the growth of
the world population and the depletion of land reserves combine to
enhance demand. Also, increasing environmental constraints will
limit the availability of traditional land-based resources;
nevertheless, new offshore development must proceed in a manner
whereby the marine environment is not plundered but protected and
conserved. The challenge to develop ocean resources with
responsible environmental stewardship will require greater
leadership than the development of the technologies of
exploitation.
