biogeochemical

音标发音

This correlation suggests that a warming climate is driving this biogeochemical change, Drevnick says.
德莱夫尼克说，这种关联性表明，气候变暖正在推动这种生物地球化学变化。
"This is a reversal in trend in a major biogeochemical process that's been in place for thousands of years, all as a result of human emissions of CO2, " he said.
“在成千上万年的生物地球化学主要进程中，其发展趋势将会转变，所有的一切仅因为人类排放二氧化碳。” 他这样说。
To determine how climate change alters this biogeochemical cycle in Arctic lakes, Drevnick's team analyzed sediment cores from nine lakes in the Canadian Arctic and in Svalbard, Norway.
要确定气候变化是如何改变北极湖泊的这种生物地球化学循环系统，德莱夫尼克的研究小组分析了来自加拿大北极地区和挪威斯瓦尔巴德9个湖泊的沉积物岩心样本。

In river basins, soils, groundwater, riparian zones, streams, rivers, lakes and reservoirs act as successive filters in which the hydrology, ecology and biogeochemical processing are strongly coupled and together act to retain a significant fraction of the nutrients transported.

Following the recommendations of the Framework for Ocean Observing, the emphasis of the GOOS Steering Committee will be the identification of Essential Ocean Variables, (EOVs), the physical, chemical, biogeochemical or ecological parameters of the oceans which can be measured, observed and used to continuously assess the state of the oceans.
