Climatic Change, 1978
Desertification can be a particularly visible consequence of climatic change. While considerable research has been devoted to terrestrial desertification in recent years, it is in the sea that biological deserts comprise 90% of the total area. Productive ocean ‘oases’ or coastal upwelling areas comprise less than .1% of the total ocean area but yield ...

Science, 1962
The quantity and chemical composition of oceanic detritus in the northeastern Pacific Ocean has been measured at different depths from the surface to 3000 meters. The results indicate that oceanic detritus must be considered as a source of food for secondary producers.

Ocean geography for ocean science
GeoJournal, 1999The expanding needs for ocean resources, together with the design and diffusion of new kinds of deep-ocean and coastal management patterns, have changed profoundly in the transition from modern to post-modern society. As a result, the scientific approach to the ocean has also undergone profound changes, which have marked the epistemology of disciplines,

On 19 April 1866, the 2300 ton steamer Agamemnon, set out from Liverpool on a historic voyage. Agamemnon was a square-rigged barque, powered by high pressure compound engines, and she carried cargo for Penang, Hong Kong, and Shanghai. Within a few months two sister ships, Ajax and Achilles, had set out on similar journeys.

Ocean protection covers activities in two types of area: within and beyond national jurisdiction. It seeks to reduce serious pressures on the marine environment, such as: overfishing, ocean acidification, climate change, and pollution. The ocean itself is a complex social-ecological system, a dense network of carbon, heat, plankton, and fish. The ocean

Archives of Neurology, 1991
The Journal of the American Medical Association and its family of specialty journals are addressing the issue of access to medical care. Matthew Menken presents a thoughtful look at this problem in a special article in this issue. 1 One of the major priorities in most industrialized nations is the provision of universal access to high-quality medical ...

Annual Review of Earth and Planetary Sciences, 1991
Certain robust, long-lived eddy features in t he world's ocean have come to be k nown as rings. The nomenclature stems from Fuglister 1 (1972), who c oined t he name based on the c ircle or ring of Gulf Stream waters t hat surrounded a class of eddies formed from t he G ulf Stream through the pinch-off of meanders . Here it s uffices to define rings as

The phenomena of tides are a matter of common experience: ocean tides under the influence of the Moon and the Sun, differences of the surface level of the oceans reaching several meters, following well-established cycles. In the present chapter we propose a first step in the general and classical mathematical formulations of the tidal potential and ...
