    The influence of phytoplankton aggregation on sedimentation : a model study (1999)
    Kiel : Inst. für Meereskunde, Abt. Marine Planktologie
    Details Availability
    Keywords: Report ; Dissertation ; Hochschulschrift ; Meereskunde ; Sedimentation ; Phytoplankton ; Kohlendioxidfixierung
    Description / Table of Contents: Es wird ein Modell für Phytoplanktonaggregation präsentiert in dem die Aggregationsgleichungen und die Sedimentation auf einem kontinuierlichen Größenspektrum des Phytoplanktons gelöst und in 0-dimensionale und 1-dimensionale Modelle für die biogeochemischen Kreisläufe implementiert wurden. Das Modell wird mit anderen Modellen verglichen. Ferner wird das Modell für Simulationen des nördlichen Atlantiks und des Arabischen Meeres benutzt. Darstellung und Diskussion der Ergebnisse.

    Representing phytoplankton aggregates in biogeochemical models (1999)

    Description: We show how to represent changes in the distribution of size and sinking speed of marine particles by a two-parameter model. In contrast to fully size-resolved models, this representation holds promise for constructing ocean biogeochemical models with detailed spatial resolution and seasonally varying sinking speed. We treat the mass and number of particles as separate state variables, each obeying its own conservation law. Average size and sinking speed of particles change as particles aggregate or the largest particles sink out. The distribution of particle sizes is assumed to follow a power law, whose exponent changes as a function of average particle size. Compared to biogeochemical models with constant particle sinking speed, our approach imposes a modest increase in computational cost and produces important effects like more rapid sinking immediately following a phytoplankton bloom. Compared to models that use hundreds of size classes to represent the detailed evolution of particle size distribution, our approach offers a major reduction in computational cost, while maintaining realistic behaviour like the sudden onset of significant aggregation when particles are sufficiently abundant.
