Riverine contribution of biogenic silica to the oceanic silica budget
Biological uptake of dissolved silicate (DSi) and formation of biogenic silica (BSi) during diatom growth modifies the form of Si carried from the continents to the world ocean. Significant concentrations of BSi, averaging 28.0 pmol L-l, are found in all sizes of rivers. The global contribution of BSi carried by rivers was estimated as 1.05 ? 0.20 Tmol Si year’. Combined with the global mean ri...
متن کاملcontribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...

[1] Using a three-dimensional physical-biogeochemical model, we have investigated the modeled responses of diatom productivity and biogenic silica export to iron enrichment in the equatorial Pacific, and compared the model simulation with in situ (IronEx II) iron fertilization results. In the eastern equatorial Pacific, an area of 540,000 km was enhanced with iron by changing the photosynthetic...
متن کاملVertical budgets for organic carbon and biogenic silica in the Pacific sector of the Southern Ocean , 1996 – 1998
During the 1996–1998 Antarctic Environment and Southern Ocean Process Study (AESOPS), a component of US JGOFS, we obtained seasonal or longer-term data sets on the rates of production, vertical transport, remineralization and burial of particulate organic carbon (POC) and biogenic silica (BSiO2) in the Southern Ocean at 1701W between 551S and 681S. The AESOPS data records enable us to construct...
متن کاملUpper ocean export of particulate organic carbon and biogenic silica in the Southern Ocean along 1701W
Upper-ocean fluxes of particulate organic carbon (POC) and biogenic silica (bSi) are calculated from four US JGOFS cruises along 1701W using a thorium-234 based approach. Both POC and bSi fluxes exhibit large variability vs. latitude during the seasonal progression of diatom dominated blooms. POC fluxes at 100m of up to 50mmolCm 2 d 1 are found late in the bloom, and farthest south near the Ros...
