Abstract:: Factor analysis of radiolarian species from the tops of 34 gravity cores in the area extending from 5°N to 45°N, 95°W to 155°W, yields five factor assemblages which are related to the present surface circulation: 1) a Pacific Equatorial Water assemblage; 2) a California Current assemblage; 3) a North Equatorial...

Abstract:: A new technique for determining the amount of opal in deep-sea sediments of any age is described. Using a normative calculation, a portion of the analytical silica concentration of sediments is subtracted as non-biogenic in proportion to the concentration of aluminum in the sample. The ratio of SiO₂:Al₂O₃ used to...

Creator:: Molina-Cruz, Adolfo
Abstract:: The distribution patterns of quartz and opal contents and the distribution patterns of radiolarian assemblages, in the sediments of the southeastern Pacific, are largely controlled by both the surface winds and the mixed-layer oceanic circulation. The distribution pattern of quartz is related to eolian and ice-rafted transport, as well as...
