Primary productivity data from Pliocene of northern Indian Ocean is lacking. Marine siliceous organisms viz., diatoms, radiolarians, silicoflagellates and siliceous sponges uptake dissolved silica (dSi) from the seawater. The biological uptake of dissolved silica (dSi) from the seawater and subsequent ...
in five cores from low-productivity regions of the Atlantic and Indian Oceans. All cores exhibit a peak in productivity 45.5 Ma, coincident with the Indo-Pacific bloom. This suggests that nutrients were not shifted away from low-productivity regions nor out of the Atlantic Ocean. Instead, it ...
Estimated survival rates of fry through the end of the first year in the ocean were generally <0.5%. Estimated survival rates of hatchery-origin fish from egg to the end of the first year in the ocean were on average about four times greater than the estimated maximum rate for natural-...
Location of Shangyu county. Full size image Data sources Research data in this study include energy-consumption data, land-use data, night-light remote sensing images, industry data, buildings data, net ecosystem productivity (NEP), carbon flux from inland water and agricultural input indices.

Higher SSOMF has been linked to increased microbiological activity in the surface ocean or sample seawater (O’Dowd et al., 2004; Prather et al., 2013). But other studies have shown that high productivity and low productivity seawater yield similar SSOMFs in artificially generated sea spray ...
it is good to believe that the labor transfer from low productivity sector to high productivity sector improves the economic efficiency and provides source of economic growth. Wage incomes are more and more important income sources of rural house 因为农村到都市劳动力灵活性在中国控制迁移,相信是好从...
Thus, it appears the biological productivity is suppressed due to iron deficiency, in combination with the severe seasonal effects of wind mixing on the light climate, as well as regional silicate limitation for diatoms. 展开 关键词: diatom dissolved Fe Southern Ocean ...
