    Volcanic ash layers in deep-sea sediments and their petrological significance (1973)
    Elsevier
    In:  Earth and Planetary Science Letters, 17 (2). pp. 397-407.
    Details
    Publication Date: 2017-02-14
    Description: Volcanic ash layers, which represent the products of volcanic activity within the ocean basins, are common in sedimentary cores taken near Cobb Seamount and on the actively spreading Gorda and Juan de Fuca Ridges. Petrographic and chemical analyses of the glass shards from these deposits have revealed that they are unaltered and are as chemically representative of local volcanic events as are the glassy margins of fresh pillow basalts recovered from the same areas. The presence of unhydrated glass shards in samples as old as 3.8 my is in direct conflict with published hydration rates of both terrestrial and submarine volcanic glasses. A study of a sequence of ash layers from Cobb Seamount, which spans in time much of the Seamount's history, indicates that the volcanic products from Cobb Seamount have had alkaline affinities and that its eruptions have been becoming progressively enriched in Al2O3. Recent experimental petrological evidence and the data on the chemical compositions of Cobb Seamount and the adjacent Juan de Fuca Ridge magmas are in agreement with the hypothesis that magmas are being generated at progressively greater depths beneath Cobb Seamount as it migrates away from the Juan de Fuca Ridge.

    Mesozoic palaeogeography of the Southern Cape, South Africa (1973)
    Elsevier
    In:  Palaeogeography, Palaeoclimatology, Palaeoecology, 13 (3). pp. 203-213.
    Details
    Publication Date: 2016-04-08
    Description: Four palaeogeographical reconstructions are presented for the southern Cape covering the period Late Permian to Late Cretaceous. This time spans the commencement to an advanced stage of breakup of Gondwanaland, during which the area moved from a mid-continental, high latitude, to an ocean-dominated, middle latitude position. These movements can be traced in facies changes and erosional cycles associated with the rift between West Gondwana and Antarctica (proto southwest Indian Ocean) and the later rift between South America and Africa (proto southeast Atlantic Ocean).

    Post-Palaeozoic stratigraphy of the eastern Agulhas Bank, South African continental margin (1973)
    Elsevier
    In:  Marine Geology, 15 (1). pp. 1-23.
    Details
    Publication Date: 2016-04-15
    Description: The Agulhas Bank, which forms the continental margin on the southern tip of Africa, consists of a thick Meso-Cainozoic sedimentary sequence (up to 6.2 km) resting on and behind pre-Mesozoic continental acoustic basement. The stratigraphy of this sequence is outlined and its history and facies variations mentioned where they are known. Refraction seismic velocity and bottom sample data indicate a basic three-fold subdivision of the Mesozoic sequence, which can be correlated with the onshore succession in the Algoa Basin. It is separated by a major hiatus from the Cainozoic sediments, which consist of a Palaeogene and Neogene sequence subdivided by another well-defined level of erosion. Various formations within the Cainozoic are defined and named. An outline of the bathymetry of the eastern Agulhas Bank is also given.

    Vertical coherence of short-periodic current variations (1971)
    Elsevier
    In:  Deep Sea Research and Oceanographic Abstracts, 18 (2). pp. 179-191.
    Details
    Publication Date: 2016-09-22
    Description: A study is described which attempts to obtain information about the vertical correlation of ocean currents at frequencies higher than inertial. Current velocity and temperature data for sensor separations of 4–12 m were taken with a mooring at ‘Site D’. The coherence and phase spectra for velocity component pairs reveals that motions are rotational at low frequencies. A cut-off frequency exists above which coherence drops to low values. The limiting frequency coincides with the minimum Väisälä frequency of the total water column. These cross-spectral properties support the assumption that the motion in this frequency range is governed by internal wave dynamics. The coherence and phase spectra of temperature pairs indicate that a field of temperature structure is superimposed on the mean field which is weakly correlated to the field of motion.

    The fine-structure contamination of vertical velocity spectra in the deep ocean (1974)
    Elsevier
    In:  Deep Sea Research and Oceanographic Abstracts, 21 (1). pp. 37-46.
    Details
    Publication Date: 2018-03-08
    Description: When determining vertical velocity spectra from temperature time series and the mean vertical temperature gradient, restrictions may arise friom the existence of fine-structre. Phillips (1971) and Garrett and Munk (1971_ have shown that the fine-structure contamination of internal gravity wave spectra can be written as a function of some statistical properties of the internal wave field and the vertical wave number spectrum of the fine-structure. A consistent set of current and temperature data was obtained during an experiment at Site D to study this problem. The wave number spectrum of the vertical temperature fine-structure and the apparent frequently spectrum of internal waves are determined from these data. In contrast to the asasumptions in the above models, our fine-structure data imply a wave number spectrum proportional to (wave number)−3 in the range which is important here. Using the above set of data, a model is suggested to describe the effect of fine-structure on vertical velocity spectra computed with the mean vertical temperature gradient. It indicates a maximum fine-structure contamination of the true frequency spectrum of internal gravity waves in the middle of the internal wave band, with less contamination at low and high frequencies.

    On the in situ measurement of temperature and electrical conductivity of sea-water (1963)
    Elsevier
    In:  Deep Sea Research and Oceanographic Abstracts, 10 (3). pp. 269-277.
    Details
    Publication Date: 2016-09-22
    Description: After some brief comments on the measurement of temperature and electrical conductivity in oceanography, the measuring probes suitable for in situ measurements are reviewed. Then the method of measurement is described using an improved model of the so-called bathysonde. This makes possible a continuous recording of temperature, conductivity, and pressure with high accuracy in great depths. Measurements from the Skagerrak and from the Mediterranean are considered. Finally, problems are discussed which arise when evaluating electrical conductivity and temperature from in situ measurements.

    On the processes of renewal of the North Atlantic deep water in the Irminger Sea (1964)
    Elsevier
    In:  Deep Sea Research and Oceanographic Abstracts, 11 (6). pp. 881-890.
    Details
    Publication Date: 2016-09-22
    Description: Observations of temperature and electrical conductivity by a recording in situ salinometer are discussed in respect oo the physical processes connected with the renewal of North Atlantic deep water. The measured fine structure of the layering suggests that the downward movement of cooled surface water is combined with horizontal mixing down to more than 1000 m depth. This is confirmed by the existence of water elements which have slightly different temperature and salinity. Curves of temperature, conductivity, and salinity and T-S diagrams are shown.
