| This study concerns the numerical simulation of the behaviour of pelagic systems in marine environments by means of a coupled biological and physical model. The physical model is based on the resolution of the Navier-Stokes, temperature and salinity equations in the 3 dimensions of space with a turbulent closure model consisting of 2 supplementary equations ( Kappa - epsilon model). The tridimensional biological model distinguishes 5 areas: phytoplankton (alive and dead); dissolved inorganic nitrogen; herbivores (essentially copepods); and zooplanktonic wastes (dead bodies and fecal pellets). Other than biological relations (nutrition, excretion,...), the sedimentation of biogenic particles (alive and dead phytoplanktonic cells, dead herbivores) are also... |

| A survey involving both permanent mooring and high frequency sampling was carried in the Bay of Banyuls-sur-Mer during the fall of 1999 to assess the effect of strong and unpredictable meteorological events on the functioning of a coastal Mediterranean ecosystem. A severe winter storm took place on 12 November, which generated waves with a significant height of 7 m and a sea surface rise of about 0.5 m. The near-bottom current speed at 24 m reached 30 cm s(-1). This storm induced a significant increase in total suspended matter through resuspension and then a subsequent increase in gross sedimentation rates. It also resulted in an increase of the proportion of refractory particulate organic matter in the water column. It also tended to increase nutrient... |
