Off-shelf fluxes of labile materials by an upwelling filament in the NW Iberian Upwelling System
Daily changes in the concentrations of carbon and nitrogen species were monitored during the course of a Lagrangian drifter experiment in a recurrent upwelling filament south of Cape Finisterre (NW Iberian Upwelling System). A drifting buoy released at the southern edge of the upwelling centre generated by the Cape moved 60km southwestwards from 3 to 7 August 1998. Organic matter in the 50m dee...
متن کاملPhysical–biological coupling in the coastal upwelling system of the Ría de Vigo (NW Spain). I: In situ approach
The fate of the inorganic and organic nitrogen trapped in the coastal upwelling system of Ría de Vigo (NW Spain) was studied at the 2 to 4 d time-scale during July and September 2002. A transient geochemical model was applied to the measured residual currents and concentrations of inorganic nitrogen (NT), and dissolved (DON) and particulate (PON) organic N to obtain (1) the net balance of input...
متن کاملPhysical–biological coupling in the coastal upwelling system of the Ría de Vigo (NW Spain). II: In vitro approach
The metabolism of the pelagic ecosystem of the Ría de Vigo (NW Spain) was studied during July and September 2002. Measurements of primary production (Pg) and respiration (R) were performed at a single site twice a week at 5 depths, from surface to bottom. In July, the net community production (NCP = Pg – R) decreased along with Pg, from 0.73 under strong upwelling to 0.14 g N m–2 d–1 under weak...
متن کاملStoichiometry of the degradation of dissolved and particulate biogenic organic matter in the NW Iberian upwelling
[1] The average composition of the dissolved and particulate products of early degradation of marine phytoplankton has been established for the first time in a coastal upwelling system using a mixing analysis along isopycnal surfaces combined with a stoichiometric model. About 17–18% of the mineralized organic matter is derived from the decomposition of organic particulates, and 16–35% is from ...
متن کاملEstuary-ria exchange of cadmium, lead and zinc in the coastal system of the Ria of Vigo (NW Iberian Peninsula)
Little research has been done on the land-sea exchange of trace elements, which is particularly applicable to ria coasts. In particular, trace metal enrichment in the inner part of the Ria of Vigo (the San Simon Inlet) has been observed from sediment studies but there is no information about Cd, Pb and Zn fluxes through the Rande Strait, which is the natural boundary of the estuary-ria water ex...
