For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy’s Oak Ridge National Laboratory.

UAH graduate student uncovers link between forest fire smoke, pollution events
October 17, 2017 04:40 PM - University of Alabama Huntsville

Smoke from forest fires might contribute to more than half of certain gritty air pollution events in the continental U.S. during the summer, and as much as 20 percent of those events throughout the year, according to new research at The University of Alabama in Huntsville (UAH).

Rivers Carry Plastic Debris Into The Sea
October 17, 2017 11:10 AM - Helmholtz Centre for Environmental Research - UFZ

Every year, millions of tonnes of plastic debris ends up in the sea - a global environmental problem with unforeseeable ecological consequences. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers.

NOAA observing buoys validate findings from NASA's new satellite for measuring carbon dioxide
October 17, 2017 08:16 AM - NOAA

The strong El Niño event of 2015-2016 provided NASA and NOAA an unprecedented opportunity to test the effectiveness of the newest observation tool to measure global atmospheric carbon dioxide concentrations -- NASA’s Orbiting Carbon Observatory-2 satellite or OCO-2.

Observations of carbon dioxide concentrations over the tropical Pacific from the satellite were validated by data from NOAA’s Tropical Pacific Observing System of buoys, which directly measure carbon dioxide concentrations at the surface of the ocean.

Study suggests oysters offer hot spot for reducing nutrient pollution

When it comes to oysters and their role in reducing nutrient pollution, a new study by researchers at William & Mary’s Virginia Institute of Marine Science gets right to the guts—and the shell—of the matter.

Study Casts Doubt on Warming Implications of Brown Carbon Aerosol from Wildfires
October 12, 2017 12:23 PM - Washington University in St. Louis

As devastating wildfires continue to rage in the western U.S. and Canada, a team of environmental engineers at Washington University in St. Louis have discovered that light-absorbing organic particulate matter, also known as brown carbon aerosol, in wildfire smoke loses its ability to absorb sunlight the longer it remains in the atmosphere.
