The Inner Shelf Response to Wind-Driven Upwelling and Downwelling*
A two-dimensional numerical model is used to study the response to upwellingand downwelling-favorable winds on a shelf with a strong pycnocline. During upwelling or downwelling, the pycnocline intersects the surface or bottom, forming a front that moves offshore. The characteristics of the front and of the inner shelf inshore of the front are quite different for upwelling and downwelling. For a...
متن کاملCoastal Upwelling Drives Intertidal Assemblage Structure and Trophic Ecology
Similar environmental driving forces can produce similarity among geographically distant ecosystems. Coastal oceanic upwelling, for example, has been associated with elevated biomass and abundance patterns of certain functional groups, e.g., corticated macroalgae. In the upwelling system of Northern Chile, we examined measures of intertidal macrobenthic composition, structure and trophic ecolog...
متن کاملInsights into the Microbial and Viral Dynamics of a Coastal Downwelling-Upwelling Transition
Although previous studies have described opposing states in upwelling regions, i.e., the rise of cold nutrient-rich waters and prevalence of surface warm nutrient-poor waters, few have addressed the transition from one state to the other. This study aimed to describe the microbial and viral structure during this transition and was able to obtain the taxonomic and metabolic compositions as well ...

متن کاملPlankton trophic structure and particulate organic carbon production during a coastal downwelling-upwelling cycle
We evaluated plankton trophic structure in a short-term temporal survey performed throughout a downwelling–upwelling cycle at the SE Brazilian coast. Size-fractioned phytoplankton biomass (PB), microzooplankton (MiZA) and mesozooplankton (MeZA) abundances along with primary (PP) and bacterial production (BP) were estimated for 5 consecutive days at a fixed station in the Cabo Frio upwelling cor...
