Cephalopod paralarvae and upwelling conditions off Galician waters (NW Spain)
A total of 103 cephalopod paralarvae were sampled during June 1995 in Galician waters (NW Spain). Samples were taken with Bongo nets of 300 and 500 μm mesh size at 48 sampling stations along 10 transverse transects ranging from 80 to 600 m water depth. Paralarvae of loliginid squid were most abundant (40%). The Rhynchoteuthion paralarvae of ommastrephid squid accounted for 25%, whereas sepiolid...
متن کاملMethane emissions from the upwelling area off Mauritania (NW Africa)
Coastal upwelling regions have been identified as sites of enhanced CH4 emissions to the atmosphere. The coastal upwelling area off Mauritania (NW Africa) is one of the most biologically productive regions of the world’s ocean but its CH4 emissions have not been quantified so far. More than 1000 measurements of atmospheric and dissolved CH4 in the surface layer in the upwelling area off Maurita...
متن کاملOff-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 کاملContributions of mesozooplankton to vertical carbon export in a coastal upwelling system
Mesozooplankton can directly impact global biogeochemical cycles by repackaging particulate organic carbon (POC) into dense, rapidly sinking fecal pellets and by undertaking vertical migrations that transport carbon and nutrients to depth. We assessed these contributions of mesozooplankton to vertical flux in the California Current Ecosystem, a productive but spatiotemporally variable coastal u...
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...
