Abstract |
Suspended Particulate Matter (SPM) is a key determinant of biological processes, biogeochemical fluxes and ecosystem functioning in coastal ecosystems. While SPM dynamics are primarily controlled by hydrodynamic forcing as well as the physical and chemical properties of mineral particles, it is becoming increasingly clear that biological activity also affects the size and settling of particle aggregates. The release of exopolymeric substances (EPS) by phytoplankton and the formation of sticky marine gels will stimulate flocculation, while bacterial mineralisation and grazing can transform the flocs. To date, little is known about the relative importance of physical and biological processes for SPM dynamics in highly productive yet turbid shallow coastal areas like the Belgian Continental Shelf. With BG-PART, we aim to assess the interactions and feedback mechanisms between biological activity and sediment mineralogy for SPM dynamics and ecosystem functioning during the development of the spring bloom. |
