Hurricanes cause severe impacts on forest ecosystems in the United States. These events can substantially alter the carbon biogeochemical cycle at local to regional scales. We selected all tropical storms and more severe events that made U.S. landfall be
Commonly, the heterotrophic prokaryotic carbon demand (PCD) of deep-sea microbes is calculated from heterotrophic biomass production and respiration measurements based on shipboard incubations under atmospheric pressure conditions, assuming that pressure changes do not affect metabolic rates. Estimates of the...
Using SCIAMACHY data from 2003-2009, scientists have detected an increase inatmospheric carbon dioxide(CO2) - one of the most important greenhouse gases that contributes to global warming - by about 2 parts per million (ppm). The animation shows the column-averaged mixing ratio of CO2, denoted ...
PAH production has, indeed, been observed in WR stars29, and while subsequent SN type-Ib/c explosions are generally expected to destroy most dust produced in the preceding WR phase, models have shown that carbonaceous grains produced by binary carbon-rich WR stars can survive30. However, for ...
In order to mitigate global warming, the international communities actively explore low-carbon and green development methods. According to the Paris Agreem
All this is illustrated with stunning Aurora Borealis images.” Tom Bol, Professional Photographer “I just wanted to take a moment to say Thank You for writing your book, “How to Photograph the Northern Lights.” It had been a dream of mine not only to see but to photograph the ...
Importantly, it has to be noted that there are no un-expected peaks in the XPS spectra, which indicates that the pyrolytic carbon pillars do not contain toxic elements in significant quantities. 3.4. Pyrolytic carbon pillar electrode fabrication Fig. 8 shows optical microscope images of the final...

Because the intensity of bioturbation highly depends on the food supply (i.e., the flux of carbon arriving in the sediment)13, the activity of new bioturbators as ecosystem engineers could have impacted the carbon cycle by increasing the provision and use of fresh organic matter in deeper ...
