    Radiocarbon age determinations of coral and reef cores from the Philippines off North Bohol and Olango
    PANGAEA
    In:  Supplement to: Grobe, Hannes; Willkomm, Horst; Wefer, Gerold (1985): Internal structure and origin of the Double Reefs of North Bohol and the Olango Reef Flat (Philippines). The Philippine Scientist, 22, 83-94, hdl:10013/epic.11655.d001

    Description: Nine holes were drilled with a submersible hydraulic drill into the slopes and reef flats of the Caubyan and Calituban reefs as well as of Olango Flat. The maximum depth of core penetration was 11 m. 14C ages showed that the Caubyan and Calituban reefs were formed within the last 6,000 years. Corals settled on a pre-existing relief parallel to the island of Bohol, building a framework for other carbonate-producing organisms. The reef flat south of Olango has a different structure. Formation took place during a Pleistocene high sea level, e.g. 125,000 years ago.

    14C activity of Antarctic lichens (1992)
    PANGAEA
    In:  Supplement to: Willkomm, Horst; Bölter, Manfred; Kappen, Ludger (1992): Age estimation of Antarctic Macrolichens by radiocarbon measurements. Polarforschung, 61(2/3), 103-112, hdl:10013/epic.29685.d001

    Description: By the nuclear bomb tests during the 1950s and early 1960s, the radiocarbon content of the atmospheric CO, on the Southern Hemisphere rose within a few years from 98 to 162% of the standard recent value and then dropped to 122% (at the end of 1984). This rapid fluctuation was used to determine the lifetime of five species of lichens collected in the beginning of 1985 in the maritime Antarctic. Under the assumption that Lichens assimilate each year carbon at the same rate and that carbon once fixed at least in main branches never will be exchanged later on. The age of mature thalli of Caioplaco regalis, Ramalino tetebrata and Ustiea antarctica was determined to 32 years, while U, aurantiaco-atra and Himantormia lugubris gave an age of ca. 38 years and ca. 60 years, respectively.

    Heavy metals and carbon isotope concentrations in recent Baltic Sea sediments (1974)
    PANGAEA
    In:  Supplement to: Erlenkeuser, Helmut; Suess, Erwin; Willkomm, Horst (1974): Industrialization affects heavy metal and carbon isotope concentrations in recent Baltic Sea sediments. Geochimica et Cosmochimica Acta, 38, 823-842, https://doi.org/10.1016/0016-7037(74)90058-1
    Details
    Publication Date: 2024-02-03
    Description: Recent sediment cores of the western Baltic Sea were analyzed for heavy metal and carbon isotope contents. The sedimentation rate was determined from radiocarbon dates to be 1.4 mm/yr. The 'recent age' of the sediment was about 850 yr. Within the upper 20 cm of sediment, certain heavy metals became increasingly enriched towards the surface; Cd, Pb, Zn and Cu increased 7-, 4-, 3- and 2-fold, respectively, whereas Fe, Mn, Ni and Co remained unchanged. Simultaneously, the radiocarbon content decreased by about 14 per cent. The enrichment in heavy metals as well as the decrease in the 14C-concentration during the last 130 ± 30yr parallels industrial growth as reflected in European fossil fuel consumption within that same period of time. The near-surface sediments are affected by residues released from fossil fuels at the rate of about 30 g/m**2 yr for the past two decades. The residues have a pronounced effect on the heavy metal and carbon isotope composition of the most Recent sediments allowing estimates to be made for sedimentation, erosion and heavy metal pollution.
