The distribution of runoff through the year is referred to as the seasonal regime and is determined by the pattern of precipitation and temperature throughout the year. Extremes of flow – floods and low flows – and their time of occurrence through the year are also a product of climate ...
Here we predict that water ceases to flow for at least one day per year along 51–60 per cent of the world’s rivers by length, demonstrating that non-perennial rivers and streams are the rule rather than the exception on Earth. Leveraging global information on the hydrology, climate, ...
Throughout the rest of the manuscript, we focus on nitrogen given its role as the limiting nutrient for NPP in the Arctic Ocean2,3 (Supplementary Fig. 1). With these simulations, we estimate that terrigenous nutrients fuel 28–51% of the current annual Arctic Ocean NPP. Our results thus ...

Climate-driven runoff events resulted in elevated mercury concentrations and loadings throughout the remainder of the year. Over 90% of the annual mercury loading was carried during the 9 months from March through November. These results indicate that diffuse inputs throughout the watersheds dominate...

根据首段句子Because the saltiness of the ocean is the result of several natural influences and processed; the salt load of the streams entering the ocean is just one of these factors.可知答案,故选A。 根据第三段句子Salts become concentrated in the sea because the Sun's heat distills(蒸馏)al...
Here we show how major rivers can efficiently connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from the Congo River-mouth, with one flow tr
