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 کاملNutrient and phytoplankton biomass in the Amazon River shelf waters.
The Amazon River estuary is notable at the Amazon Continental Shelf, where the presence of the large amount of water originating from the Amazon during the river's falling discharge period was made evident by the low salinity values and high nutrient levels. Even so, the presence of oceanic waters in the shelf area was significant. Dissolved organic nitrogen was the predominant species of the n...
متن کاملUpwelling along the western coast of the Iberian Peninsula: dependence of trends on fitting strategy
We investigated upwelling variability along the western coast of the Iberian Peninsula for the period 1948−2009 by means of wind data extracted from the NCEP/NCAR reanalysis project. According to most previous studies, a remarkable weakening in upwelling intensity has been observed in the area. However, the observed linear trends are highly dependent on the length of the series. Here we show ho...
متن کاملEffects of stratification and shelf slope on nutrient supply in coastal upwelling regions
[1] An idealized, two‐dimensional numerical modeling study is presented to investigate the effects of variable shelf slope and stratification on surface mixed layer (SML) nutrient supply during upwelling. As reported previously, the physical flow regime is governed by a topographic Burger number. Gradual shelf slope and weak stratification concentrate onshore transport in the bottom boundary la...
