Strong and Dynamic Benthic-Pelagic Coupling and Feedbacks in a Coastal Upwelling System (Peruvian Shelf)
Monthly time-series data (1998–2009) of bottom water oxygen, nitrate and nitrite concentrations from the outer shelf (150m water depth) in the oxygen minimum zone offshore Peru were coupled to a layered biogeochemical sediment model to investigate benthic-pelagic coupling over multi-annual time scales. The model includes the mineralization of four reactive pools of particulate organic carbon (P...
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...
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 کاملCoastal upwelling in a warmer future
[1] Coastal upwelling helps set the physical context for marine ecosystems, and upwelling zones are among the most productive regions of the global ocean. Unlike earlier models, two state-of-the-art climate models exhibit little change during the next century in the magnitude and seasonality of coastal upwelling, but climate models are still probably not sufficiently developed (for example, the...
متن کاملDelayed coastal upwelling along the U.S. West Coast in 2005: A historical perspective
[1] The timing of the onset of coastal upwelling in spring and its intensity over the upwelling season are critical factors in the productivity and structure of the California Current ecosystem (CCE). We use an index of coastal upwelling to characterize physical forcing over the latitudinal extent of the CCE, and compare the evolution of the upwelling season in 2005 with previous years. The ons...
