Fourteen laboratories participated in this interlaboratory comparison exercise (ILC). The results indicated good analytical performance by the participating laboratories, but the results of the 210Pb dating did not reach the desired level of satisfaction.
Staal and colleagues focused on the stability of tropical rainforests in the Americas, Africa, Asia and Oceania. With their approach they were able to explore how rainforests respond to changing rainfall.
Dust blowing onto high mountains in the western Himalayas is a bigger factor than previously thought in hastening the melting of snow there, researchers show in a study published Oct. 5 in Nature Climate Change. That's because dust - lots of it in the Himalayas - absorbs sunlight, heating the snow that surrounds it.
Conservation projects aimed at protecting land-dwelling species could net major gains in helping species living in streams, lakes and wetlands with relatively minor adjustments.
Indiana University researchers analyzed these geographic regions, which include cities like New Orleans, Bangkok, and Shanghai, using a new global dataset to determine how many people live on river deltas, how many are vulnerable to a 100-year storm surge event, and the ability of the deltas to naturally mitigate impacts of climate change.
A new study by an international team of environmental scientists in the Brazilian Amazon shows that redesigned conservation projects could deliver big gains for critical freshwater ecosystems - raising hopes for the futures of thousands of species.
Researchers at the University of California San Diego report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California's San Joaquin Valley.
The 2019 Ridgecrest earthquake sequence has revealed areas of the Los Angeles basin where the amplification of shaking of high-rise buildings is greatest, according to a new report in Seismological Research Letters.
A river's only consistent attribute is change. As the Greek philosopher Heraclitus remarked, 'No man ever steps in the same river twice.' Although this dynamic nature is often out of sight and mind, forgetting about it has led to many a historical catastrophe.
The water crisis in Flint, Michigan, brought much-needed attention to the problem of potentially toxic metals being released from drinking water distribution pipes when water chemistry changes. Now, researchers reporting in ACS' Environmental Science & Technology have investigated how hexavalent chromium, known as Cr(VI), can form in drinking water when corroded cast iron pipes interact with residual disinfectant. Their findings could suggest new strategies to control Cr(VI) formation in the water supply.
