Research to be published in Science Magazine

The appearance of oxygen in the Earth's atmosphere probably did not occur as a single event, but as a long series of starts and stops, according to an international team of researchers who investigated rock cores from the northwest region of Russia. Their findings were published in the Dec. 1 issue of Science Express. Christopher Junium, a geochemist in the Department of Earth Sciences in Syracuse University's College of Arts and Sciences, was a member of the team. Read more...

A record of the past may be locked inside a mineral common to both planets 

The discovery of the mineral jarosite in rocks analyzed by the Mars Rover, Opportunity, on the Martian surface had special meaning for a team of Syracuse University scientists who study the mineral here on Earth. Jarosite can only form in the presence of water. Its presence on Mars means that water had to exist at some point in the past. The trick is in figuring out if jarosite can be used as a proxy for determining when, and under what conditions, water was present on the planet. Read more...

Data calls into question contemporary theories

Ancient fossilized clams that lived off the coast of Antarctica some 50 million years ago have a story to tell about El Niño, according to Syracuse University researcher Linda Ivany. Their story calls into question contemporary theories that predict global warming could result in a permanent El Niño state of affairs.
“The clams lived during the early Eocene, a period of time when the planet was as warm as it’s been over the last 65 million years,” says Ivany, a researcher in the Department of Earth Sciences in SU’s College of Arts and Sciences. “We used growth rings in their shells to analyze changes in year-to-year growth rate, and linked that to changes in climate that are characteristic of El Niño today.”

How hot did the Earth get in the past? A team of scientists uncovers new information

Research sheds new light on what to expect

The question seems simple enough: What happens to the Earth’s temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record.  A new study by researchers from Syracuse (SU) and Yale universities provides a much clearer picture of the Earth’s temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising.Read more...

Cutting-edge technology used in research

Laura Lautz, a hydrologist and assistant professor of Earth Sciences in Syracuse University’s College of Arts and Sciences, uses cutting-edge technology to gather data on how waste bed effluent and other contaminants move back and forth between subsurface groundwater and streams.

By laying fiber optic cable—as much as a kilometer in length—along a stream channel, Lautz and her team can instantaneously measure small but significant temperature changes to pinpoint sources of groundwater inflow and potential pollution. That’s the applied aspect of the research. But the National Science Foundation (NSF) put up more than $500,000 to fund her work using heat as a tracer for ground and surface water interaction because it is solid, basic science with many potential applications. The technique is so new only a few research groups in the country are currently using it. Read more...
