    Notizen: [Auszug] RIEBESELL ET AL. REPLY - Turpin makes two important points pertinent to the question of CO2 limitation of phyto-plankton growth. With respect to his first comment, we agree that inorganic carbon use by the common marine di-atom species needs to be rigorously tested. With the exception of ...

    Notizen: [Auszug] SIR-Leonardo da Vinci's famous sketches are accompanied by illegible notes which, viewed in a mirror, turn out to be neatly written Roman script. Reading and writing mirror script is very difficult for most people, so why did Leonardo go to the trouble? As a code, it is much too easy to crack, ...

    Notizen: [Auszug] ...Imagine yourself standing at the edge of a precipice, looking down at its foot, and then crouching at the same place on all fours.

    Notizen: [Auszug] ...Aristotle argued that human beings have five senses at their disposal. Although various other sense organs have come to light since then, this antique dogma still constrains popular imagination.

    Notizen: [Auszug] Polar organisms have adapted their seasonal cycles to the dynamic interface between ice and water. This interface ranges from the micrometre-sized brine channels within sea ice to the planetary-scale advance and retreat of sea ice. Polar marine ecosystems are particularly sensitive to climate ...

    Deep carbon export from a Southern Ocean iron-fertilized diatom bloom (2012)
    Nature Publishing Group
    In:  Nature, 487 (7407). pp. 313-319.
    Details
    Publikationsdatum: 2019-09-23
    Beschreibung: Fertilization of the ocean by adding iron compounds has induced diatom-dominated phytoplankton blooms accompanied by considerable carbon dioxide drawdown in the ocean surface layer. However, because the fate of bloom biomass could not be adequately resolved in these experiments, the timescales of carbon sequestration from the atmosphere are uncertain. Here we report the results of a five-week experiment carried out in the closed core of a vertically coherent, mesoscale eddy of the Antarctic Circumpolar Current, during which we tracked sinking particles from the surface to the deep-sea floor. A large diatom bloom peaked in the fourth week after fertilization. This was followed by mass mortality of several diatom species that formed rapidly sinking, mucilaginous aggregates of entangled cells and chains. Taken together, multiple lines of evidence—although each with important uncertainties—lead us to conclude that at least half the bloom biomass sank far below a depth of 1,000 metres and that a substantial portion is likely to have reached the sea floor. Thus, iron-fertilized diatom blooms may sequester carbon for timescales of centuries in ocean bottom water and for longer in the sediments.
