DIPPI-C Seeking Manuscripts for G-Cubed Special Issue
   Share    Share on FacebookTwitterShare on LinkedinE-mail article
The DIPPI-C working group currently is accepting manuscripts to its special theme of the Geochemical Society/AGU journal G-Cubed.

We are looking for manuscripts using carbon isotopes and/or biomarker distributions in modern and palaeo environments from organic and inorganic materials, covering all spatial and temporal scales, to understand environmental process(es). Special theme deadline is Dec. 31, 2013 (yes, next year!!!)

Stable isotopes a universal tool
Environmental Research Web    Share    Share on FacebookTwitterShare on LinkedinE-mail article
More than 250 international scientists will be meeting in the first week of September in Leipzig, Germany, to share their experiences on the latest methods and applications using stable isotopes. Stable isotopes are a tool that can be used in a wide range of areas in natural sciences and medicine as, with their help, it is possible to establish the origin of substances, and dynamic processes can be made visible.

'Weird chemistry' by microbe is prime source of ocean methane
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Up to 4 percent of the methane on Earth comes from the ocean's oxygen-rich waters, but scientists have been unable to identify the source of this potent greenhouse gas. Now researchers report that they have found the culprit: a bit of "weird chemistry" practiced by the most abundant microbes on the planet. More

Dependence of riverine nitrous oxide emissions on dissolved oxygen levels
Nature Geoscience (subscription required)    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Nitrous oxide is a potent greenhouse gas, and it destroys stratospheric ozone. 17 percent of agricultural nitrous oxide emissions come from the production of nitrous oxide in streams, rivers and estuaries, in turn a result of inorganic nitrogen input through leaching, runoff and sewage. More

Biogenic potassium salt particles as seeds for secondary organic aerosol in the Amazon
Science (subscription required)    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The fine particles serving as cloud condensation nuclei in pristine Amazonian rainforest air consist mostly of secondary organic aerosol. Their origin is enigmatic, however, because new particle formation in the atmosphere is not observed. Here, we show that the growth of organic aerosol particles can be initiated by potassium-salt–rich particles emitted by biota in the rainforest. More

Impact from humans felt on Black Sea long before Industrial Era
RedOrbit    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When WHOI geologist Liviu Giosan first reconstructed the history of how the Danube River built its delta, he was presented with a puzzle. In the delta's early stages of development, the river deposited its sediment within a protected bay. As the delta expanded onto the Black Sea shelf in the late Holocene and was exposed to greater waves and currents, rather than seeing the decline in sediment storage that he expected, Giosan found the opposite. The delta continued to grow. In fact, it has tripled its storage rate. More

Rust never sleeps
Berkeley Lab    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Rust — iron oxide — is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to a particle of rust will use thermal energy to continually move or "hop" from one atom of iron to the next. More
