    (Table 1, page 376), Composition of manganese deposits from the Gulf of Aden and the Carlsberg Ridge (1969)

    In:  Supplement to: Johnson, C E; Glasby, Geoffrey P (1969): Mössbauer Effect determination of particle size in microcrystalline iron-manganese nodules. Nature, 222(5191), 376-377, https://doi.org/10.1038/222376a0

    Description: Iron-manganese nodules from the ocean floor have been extensively studied. But, because of the fine grain size of the particles of the nodules, structural identification by X-ray and electron diffraction techniques is difficult and the mineralogy of the iron oxide phase has not been well characterized. The observation of the Mössbauer spectrum-in which each nucleus absorbs gamma-rays independently-is not limited by particle size in the same way as is the observation of Bragg peaks in diffraction measurements, in which radiation must be scattered coherently from a large number of atoms. The magnetic hyperfine splitting in the Mössbauer spectrum of magnetic materials is affected, however, when the particles are so small that they become superparamagnetic. We describe here an investigation using the 57Fe Mössbauer effect of two iron-manganese nodules in which the iron oxide phase could not be detected by X-ray or electron diffraction.

    Composition of drilled sediments and pore waters from the continental slope of the Northern Gulf of Mexico (1969)
    PANGAEA
    In:  Supplement to: Manheim, Frank T; Bischoff, James L (1969): Geochemistry of pore waters from the Shell Oil Company drill holes on the continental slope of the northern Gulf of Mexico. Chemical Geology, 4, 63-82, https://doi.org/10.1016/0009-2541(69)90040-0

    Publication Date: 2024-01-09
    Description: Pore waters were analyzed from 6 holes drilled from M.V. “Eureka” as a part of the Shell Oil Co. deeper offshore study. The holes were drilled in water depths of 600-3000 ft. (approximately 180-550 m) and penetrated up to 1000 ft. (300 m) of Pliocene-Recent clayey sediments. Salt and anhydrite caprock was encountered in one diapiric structure on the continental slope. Samples from holes drilled near diapiric structures showed systematic increases of pore-water salinity with depth, suggestive of salt diffusion from underlying salt plugs. Anomalous concentrations of K and Br indicate that at least one plug contains late-stage evaporite minerals. Salinities approaching halite saturation were observed. Samples from holes away from diapiric structures showed little change in pore-water chemistry, except for loss of SO4 and other variations attributable to early-stage diagenetic reactions with enclosing sediments. Thus, increased salt concentrations in even shallow sediments from this part of the Gulf appear to provide an indicator of salt masses at depth.

    Biomass of upper-interzonal copepod filter feeders in the Kurile-Kamchatka region (1969)
    PANGAEA
    In:  Supplement to: Vinogradov, Mikhail E; Arashkevich, Elena G (1969): Vertical distribution of interzonal copepod filter feeders and their role in communities at different depths in the Northwestern Pacific. Oceanology, 9, 400-409
    Details
    Publication Date: 2023-11-25
    Description: Vertical distribution of abundance and biomass of upper interzonal copepods Calanus cristatus, C. plumchrus, Eucalanus bungii, Metridia ochotensis and M. pacifica have been studied in the whole depth range of their occurrence. These species comprise 55 per cent of total plankton biomass in the 0-4000 m layer. The major part (90% of the population) of C. cristatus inhabit depths are above 3000 m, and of the other species - above 750-1000 m. Feeding of juveniles proceeds in the surface euphotic zone, and then adolescent animals descend to deep water. At depth 1000-2000 m they make up 〉40%, and at 2000-3000 m, about 20% of total biomass of plankton inhabiting these depths. Interzonal species serve as a food reserve for predatory deep-sea animals and as a close connection between the surface and deep-water communities that makes it possible to regard these communities as parts of a single biocoenosis.
