'Sunny day flooding' increases fecal contamination of coastal waters
ScienceDaily » Geochemistry
by
22h ago
A new study finds that 'sunny day flooding,' which occurs during high tides, increases the levels of fecal bacteria in coastal waters. While the elevated bacteria levels in the coastal waters tend to dissipate quickly, the findings suggest policymakers and public health officials should be aware of potential risks associated with tidal flooding ..read more

Laser-treated cork absorbs oil for carbon-neutral ocean cleanup
ScienceDaily » Geochemistry

Researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material's light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling. The laser treatments not only help to better absorb oil, but also work to keep water out ..read more

The Italian central Apennines as a source of CO2
ScienceDaily » Geochemistry
by
22h ago
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of rock. At depth, the heating and melting of carbonate rock leads to the outgassing of CO2 at the surface. In the central Italian Apennine Mountains, researchers have now investigated and balanced all of these processes in one region for the first time -- using, among others, analyses of the CO2 content in mountain rivers and springs ..read more

Researchers have found that modern weather models can accurately predict the energy that Earth emits and reflects into space, which directly affects the movements of low Earth-orbiting (LEO) satellites. By leveraging these models, the researchers gained insights into how LEO satellites respond to weather events below, such as tropical cyclones with tall and reflective clouds ..read more
