By John D. Isaacs

The Physical Resources of the Ocean

They include not only the oil and minerals of the bottom and the minerals dissolved in seawater but also seawater itself and the shoreline carved by the action of the sea

The Food Resources of the Ocean

The present harvest of the oceans is roughly 55 million tons a year, half of which is consumed directly and half converted into fish meal. A well-managed world fishery could yield more than 200 million tons

By S. J. Holt

Technology and the Ocean

The materials, machines and techniques that can be employed in the ocean have advanced greatly during the past decade. Major developments include superships and deep-sea drilling

The Ocean and Man

The increase of human activity in the sea presents deep problems of relations among nations. Who owns the resources of the sea, and how is the worldwide exploration of the sea to be organized?
