Georgia Tech is partnering with two Department of Energy (DOE) national laboratories to better understand how wetlands function, enabling scientists to better understand their role in controlling water quality.

Deep Dives

Earth’s average surface temperature has risen approximately 2.12 degrees Fahrenheit since the late 1800s — most of that rise in the past 40 years, according to NASA. That’s due in large part to the increase of carbon dioxide emissions into the atmosphere, caused by human activity. This has led oceans to warm, ice sheets to melt, and sea levels to rise faster — and it has accelerated the frequency of extreme weather events, such as hurricanes.

A pair of microbes on the ocean floor “eats” methane in a unique way, and a new study provides insights into their surprising nutritional requirements.

Evidence found for granite on Mars

Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth -- could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than pre

High Levels of Molecular Chlorine Found in Arctic Atmosphere

In Barrow, snow-covered ice pack extends in every directly except inland. The ultimate source of the molecular chlorine is the sodium chloride in sea salt, Huey said, most likely from the snow-covered ice pack. How the sea salt is transformed into molecular chlorine is unknown. Credit: Greg Huey.

Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports.

Scientists studying grasslands in Oklahoma have discovered that an increase of 2 degrees Celsius in the air temperature above the soil creates significant changes to the microbial ecosystem underground.

Study of Fossilized Shells Finds Little Evidence of Icebergs’ Influence on Ice Age Ocean Circulation

Scientists have thought that large iceberg surges disrupted a key ocean circulation pattern during the last North American ice age, but a new study found little evidence of a disruption during some of the major iceberg surges.

Robotic Arm Probes Chemistry of 3-D Objects by Mass Spectrometry

The scientists programmed the robotic arm to poke the sample with an acupuncture needle.
