    Living Planktonic Foraminifera at the 90°E Meridian from the Equator to the Antarctic (1969)
    American Museum of Natural History
    In:  Micropaleontology, 15 (2). pp. 237-255.
    Details
    Publication Date: 2020-06-30
    Description: The planktonic foraminiferal fauna was studied in 206 samples gathered by the Royal Research Ship Discovery II at the 90°E meridian of longitude between the equator and the coast of Antarctica. Samples were collected throughout the water column from 1500 to 0 m. Twenty-seven species were recognized, and their horizontal and vertical distributions were established. Five types of surface water masses were distinguished on the basis of differences in foraminiferal fauna, and the geographical positions of these water masses were determined and plotted. It was found that differences exist between the geographic positions of the hydrological fronts established by means of temperature and salinity data, and those determined by means of foraminiferological data. Explanations for these discrepancies are given. The percentage of empty shells with respect to the total number of foraminiferal shells at different depths was calculated.

    Ecology of Recent Planktonic Foraminifera: Part 3: Distribution in the North Atlantic during the Summer of 1962 (1967)
    American Museum of Natural History
    In:  Micropaleontology, 13 (1). pp. 87-106.
    Details
    Publication Date: 2020-06-30
    Description: Three major faunal provinces of planktonic foraminifera were recognized along two North Atlantic crossings during the summer of 1962. The subarctic assemblage consisted of Globigerina pachyderma, G. bulloides, and G. quinqueloba; the transitional (temperate) fauna was characterized by Globorotalia inflata and mixtures of subarctic and subtropical species; and the subtropical fauna was composed of 16 species, typified by Globigerinoides ruber, G. sacculifer, and Globigerinella aequilateralis. Relative and absolute abundances for each species are mapped and some ecologic relationships are described.

    Recent Foraminifera of Mangrove Swamps and River Estuaries and Their Fossil Counterparts in Trinidad (1958)
    American Museum of Natural History
    In:  Micropaleontology, 4 (1). pp. 79-92.
    Details
    Publication Date: 2020-06-30
    Description: The Recent brackish-water foraminiferal faunas of the river estuaries and mangrove swamps of Trinidad are described briefly, and notes on the distribution of species are given. Comparable brackish-water faunas of Miocene and Pliocene age are outlined, and some of the species they have in common with the Recent faunas are described. Comparisons are drawn, where possible, between conditions of deposition of fossil and Recent faunas.

    Planktonic Foraminifera as Indicators of Depositional Environment (1955)
    American Museum of Natural History
    In:  Micropaleontology, 1 (2). pp. 147-151.
    Details
    Publication Date: 2020-06-30
    Description: Tests of planktonic foraminifera are clastic particles from an off-shore source area, shoreward deposition of which is controlled by sedimentary processes. In Recent sediments, significant correlation was observed between depth and per cent of planktonic tests. Islands had a marked effect on the distribution. In fossil sediments, the varying per cent of tests may assist in locating the former strand line, direction of deepening, and possible off-shore topographic anomalies.

    Jurassic-Cretaceous Pelagic Sediments of the Western Mediterranean Zone and the Atlantic Area (1955)
    American Museum of Natural History
    In:  Micropaleontology, 1 (2). pp. 109-124.
    Details
    Publication Date: 2020-06-30
    Description: An account of the micropaleontology of the deep-sea sediments deposited in the various zones of the Tethyan geosynclines during the Jurassic and Cretaceous is presented. The study has been considerably hampered by lack of material. Most of the sediments studied came from the present western Mediterranean zone. In general, during the Jurassic (Tithonian) and Lower Cretaceous, radiolarians and globigerines predominated in the zones of subsidence, while Nannoconus and tintinnids were most abundant in the sediments of the deeper zones. Pithonella and Globotruncana predominate in Middle and Upper Cretaceous lithofacies.
