    Notes: [Auszug] Thus far, most studies of isotopic and chemical variation in hermatypic corals, and all studies of seasonal isotopic variation, have involved species with massive growth habits, partly because such corals often produce annual24 dense bands which can be used as time markers. For examination of ...

    Notes: [Auszug] GLEASON AND WELLINGTON REPLY - Dunne suggests that we were premature in attributing the coral bleaching we observed in our experiments1 to ultraviolet radiation because we did not take into account an 8% difference in PAR between treatments with and without ultraviolet; and because we did not ...

    Notes: [Auszug] A large proportion of the Caribbean corals that bleached during 1987 and 1990 were found at depths greater than 20 m. To determine whether increased ultraviolet (UV) radiation in the 280-400-nm band could have contributed to these bleaching uble protein per cm2 of coral tissue surface (Fig. 2c and ...

    Skeletal P/Ca tracks upwelling in Gulf of Panamá coral: Evidence for a new seawater phosphate proxy (2008)
    AGU (American Geophysical Union)
    In:  Geophysical Research Letters, 35 (5). L05604.
    Details
    Publication Date: 2018-03-07
    Description: The supply of limiting nutrients to the low latitude ocean is controlled by physical processes linked to climate variations, but methods for reconstructing past nutrient concentrations in the surface ocean are few and indirect. Here, we present laser ablation mass spectrometry results that reveal annual cycles of P/Ca in a 4-year record from the scleractinian coral Pavona gigantea (mean P/Ca = 118 μmol mol−1). The P/Ca cycles track variations in past seawater phosphate concentration synchronously with skeletal Sr/Ca-derived temperature variations associated with seasonal upwelling in the Gulf of Panamá. Skeletal P/Ca varies seasonally by 2–3 fold, reflecting the timing and magnitude of dissolved phosphate variations. Solution cleaning experiments on drilled coral powders show that over 60% of skeletal P occurs in intracrystalline organic phases. Coral skeleton P/Ca holds promise as a proxy record of nutrient availability on time scales of decades to millennia.
