A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry reflecting changing climate conditions over the past 35 million years.The...
Process-based terrestrial ecosystem models are increasingly being used to predict carbon (C) cycling in forest ecosystems. Given the complexity of ecosystems, these models inevitably have certain defi...
2018年4月10日,中国地质大学地球科学院和生物地质与环境地质国家重点实验室学科团队在《Nature Communications》上发表题为“Response of carbon cycle to drier conditions in the mid-Holocene in central China”(长江中游泥炭地碳循环对中全新世干旱事件的响应)的研究论文。该文第一作者为黄咸雨副教授,谢...
Trees in tropical forests are well known for removing carbon dioxide from the air and storing the potent greenhouse gas as carbon in their leafy branches and extensive roots. But a new analysis led by...
Microbiologist Kristen DeAngelis and her graduate student Grace Pold at the University of Massachusetts Amherst, with colleagues at Woods Hole Marine Biological Laboratory (MBL) and in New Hampshire, ...
In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take...
Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis. For the stud...
Microbes in streams flowing on the surface of glaciers in the Arctic and Antarctic may represent a previously underestimated source of organic material and be part of an as yet undiscovered "dynamic l...
“There is a lot of carbon frozen in the Arctic soil’s permafrost layer. If this all thaws out, prevailing thought is that the carbon in the soil could be released to the atmosphere and potentially acc...
For more than two decades, coral skeletons have been used to reconstruct records of isotopic and chemical ratios in surface seawater (for reviews, see Druffel, 1997a; Gagan et al., 2000). Here I demon...
Anthropogenically driven climate change will rapidly become Earth's dominant transformative influence in the coming decades. The oceanic biological pump—the complex suite of processes that results in ...
Williams and Follows combined their expertise to write a book targeted at honors undergraduate or graduate students, as well as at professionals in ocean science who need to learn the fundamentals of ...
Various human activities, including fossil fuel combustion and forest clearing, emit about eight petagrams (or billion tons) of carbon in the form of CO2 into the atmosphere annually. The glob...
Chemical Oceanography and the Marine Carbon Cycle reflects the two authors' wealth of research and teaching experience, and the community is fortunate that Steve Emerson was able to complete this majo...
Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the rem...
