Organic carbon buried in marine sediment serves as a net sink for atmospheric carbon dioxide and a source of oxygen1,2. The rate of organic carbon burial through geologic history is conventionally established by using the mass balance between inorganic a
We propose that the hadal zone is an important, but overlooked, sink of black carbon in the ocean.#Black carbon accumulation rates in hadal trenches in the deepest regions of the oceans could be seven-fold higher than the global ocean average, according to geochemical and isotopic analyses of...
Large amounts of atmospheric carbon can be exported and retained in the deep sea on millennial time scales, buffering global warming. However, while the Barents Sea is one of the most biologically productive areas of the Arctic Ocean, carbon retention times were thought to be short. Here we ...
set up in the living room of a local fisherman’s house, for preliminary treatment. These samples, containing vital data on organic and inorganic carbon and nutrient salts, are then sent to Xiamen University for further analysis.
The making of a sustainable vehicle fleet Are hydrogen-powered trucks the vehicles of the future? How can we transition to clean energy? Will this electric cargo plane be transporting your packages soon? Can sustainable marine fuels turn the tide in full-container-load shipping?
8. In a way, the ocean has done humans a big favour by taking in some of carbon dioxide. 相关知识点: 试题来源: 解析 答案见上8. in 句意为:在某种程度上,海洋吸收了一些二氧化碳,帮了 人类一个大忙。take in为固定搭配,意为“吸收;摄取”。故填in。
The oceanic sink of CO2 is mainly a physico-chemical response of the ocean to increasing atmospheric CO2. CO2 dissolves in surface waters and is transported from the surface to the deep ocean by ocean currents. The rate at which carbon is transported to the deep ocean is the main factor lim...
An investigation of carbon dioxide partial pressures in the atmosphere and surface ocean conducted as part of a cooperative study under the general sponsorship of the International Geophysical Year is summarized. Results are given for about 470 hours of air analyses and 200 individual surface ocean wa...
Fig. 1. Rivers entering the Northwest Pacific Ocean in mainland China. There are six large rivers: the Songhua (#R1), Liaohe (#R2), Haihe (#R3), Huanghe (#R4), Changjiang (#R5), and Zhujiang (#R6) rivers. The Zhujiang River is composed of the Xijiang, Beijiang, and Dongjiang rive...
As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the ocean, and UConn researchers have found high CO2 concentrations in water can make fish grow smaller.
