The Amazon Basin lies across the equator, so the climate is established by the motion of the equatorial low pressure region. The result is a very rainy wet season and a very dry dry season with two transitions. The wet season is characterized by short periods of rain several times each day, with time distribution of rainfall similar to that expected ...

Whether Amazonia is a carbon-dioxide source or sink has a significant effect on estimates of the global carbon budget. On an annual basis, El Nino, and its influence on precipitation in the region, seems to be a controlling factor.

Isoprene over the Amazon Basin
Journal of Geophysical Research: Atmospheres, 1988Data obtained during the 1985 ABLE expedition to the Amazon are used to describe the diurnal and vertical variations of isoprene. Isoprene is a natural hydrocarbon emitted by many species of trees, particularly those in tropical forests. The concentrations of isoprene at lower levels in the atmosphere undergo large diurnal variations, with the highest ...

Introduction Since the arrival of human beings about 12 000 years ago, wetlands have been favorite colonization areas because of their rich food resources. On Marajó Island at the mouth of the Amazon River and in its lower course, Amerindians built large chiefdoms on elevated places that provided protection against flooding (Roosevelt 1999).

Cenozoic tectonics of Amazon Mouth Basin
Geo-Marine Letters, 1998The Cenozoic shelf margin of the Amazon Mouth Basin is characterized by a thick prograding prism of siliciclastic sediments. This prism, composed mainly of Upper Miocene and younger sediments, overlies a Lower Tertiary carbonate shelf. Two tectonic–sedimentary models for the area were developed with the aid of new deep-reflection seismic data ...

Beriberi is, as yet, a very common disease in the Brazilian portion of the Amazon Basin, and that means nearly the whole of the greatest river basin in the world. The view of some foreign physicians in regard to this disease in Brazil is that perhaps beriberi here may be different from that met in other portions of the globe. After having seen beriberi

Geological Development of Amazon and Orinoco Basins
2011This chapter examines the geological development of the Orinoco and Amazon River basins. It analyzes the evolution of aquatic Amazonian ecosystems from the Late Cretaceous to the Quaternary period and provides and considers the potential impacts on the development of modern Amazonian fish faunas.

Agricultural Alternatives for the Amazon Basin
BioScience, 1985In a study of the humid tropical ecosystems and especially lowland forests, the National Research Council (1982) concluded that these ecosystems "represent a very important, underexploited resource for tropical countries and that, as population pressures increase in these countries, rapid and extensive development will and must take place if even the ...
