Distribution and abundance of coastal fish and macro-invertebrates in the Galapagos Islands

Creator:: Figueroa, Diego
Abstract:: The Galapagos Islands, located off the coast of Ecuador, have a spatially diverse marine environment suitable for a variety of species with different climatic requirements. A year-long inventory program was carried out in 2000-2001 to provide baseline data on the abundances and distribution of coastal fish and macro-invertebrates. The purposes...

Density separation of clay minerals

Creator:: Nelsen, Terry A.
Abstract:: Illite, chlorite, montmorillonite and kaolinite, as well as natural marine sediments and mixtures of the standards were subjected to density separation by centrifugation in a linear heavy-liquid gradient. The density layers yielded by centrifugation were recovered and analyzed by X-ray diffraction. Separates were not monomineralic but rather were polymineralic usually...

Two zoogeographic studies of deep sea benthic gammarid amphipods

Creator:: Dickinson, John J. (John Joseph), 1946-
Abstract:: Two separate studies on the distribution of gammarid amphipods in the bathyal and abyssal benthic environments demonstrated that different assemblages could be found at a single depth over distances on the order of 100 kilometers. These studies evaluated changes in the species composition and relative abundance of the amphipod assemblage...

Antarctic intermediate water in the South Pacific Ocean

Creator:: Johnson, Ron (Ronald E.)
Abstract:: The distribution of Antarctic Intermediate Water in the South Pacific has been examined using a model of horizontal advection, along the Sigma-t surface 27.10, with three point vertical mixing. The core of the Antarctic Intermediate Water mass was traced from the Antarctic Convergence northward. The charts used to describe the...

A calculation of flushing times and pollution distribution for the Columbia River estuary

Creator:: Neal, Victor Thomas
Abstract:: The probable pollution distribution and flushing times have been calculated for the Columbia River Estuary, a coastal plain estuary. The pollution distribution was determined by the fresh water fraction and by the diffusion equation. The flushing times were calculated by the modified tidal prism method and by the fraction of...

Surface sediments of the Panama Basin : coarse components

Creator:: Kowsmann, Renato O.
Abstract:: The abundance and distribution of biogenic, terrigenous and volcanic particles in the Panama Basin are markedly dependent on bottom topography and dissolution of calcite in the deeper parts of the basin. Of the coarse fraction (>62μ), foraminiferal tests and acidic volcanic glass shards are concentrated on the Cocos and Carnegie...
