Contributions 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 کاملShort-term meso-scale variability of mesozooplankton communities in a coastal upwelling
31 32 Abstract The short-term, meso-scale variability of the mesozooplankton community present in the coastal upwelling system of the Ría de Vigo (NW Spain) has been analysed. Three well-defined communities were identified: coastal, frontal and oceanic, according to their holoplankton-meroplankton ratio, richness, and total abundance. These communities changed from summer to autumn due to a shi...
متن کاملPartitioning of physical and biogeochemical contributions to short-term variability of pCO2 in a coastal upwelling system: a quantitative approach
A considerable body of literature has addressed the role that coastal upwelling systems may play in global processes, especially in the ocean carbon cycle. It is often difficult to separate the effects of physical and biogeochemical processes on the partial pressure of carbon dioxide (pCO2) in coastal upwelling systems due to the tight coupling between these processes. In this work we propose a...

Coastal 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...
