The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study led by CIRES and NOAA researchers. The team’s unexpected finding suggests that in the U.S. West and elsewhere, certain efforts to reduce harmful wintertime air pollution could backfire.

Groundwater containing excess nitrogen from agricultural fertilizers likely contaminated coral reefs on the Cook Islands during the second half of the 20th century, continuing for years after fertilizer use stopped, according to a new study. The finding suggests human activities have long-lasting impacts on coral reef communities and could be contributing to their decline.

Researchers have successfully quantified Earth’s vibrational “hum” using seismic instruments on the bottom of the ocean. A new study determined at the ocean bottom the frequencies at which the Earth naturally vibrates, and confirmed the viability of using ocean instruments to study the phenomenon.

Dark fiber: Using sensors beneath our feet to tell us about earthquakes, water and other geophysical phenomena
Scientists have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.

A research team took to the lab to recreate the magmatic melt that once formed the lunar surface and uncovered new insights on how the modern moonscape came to be. Their study found found that one of the great mysteries of the lunar body’s formation – how it could develop a crust composed largely of just one mineral – cannot be explained by the initial crust formation and must have been the result of some secondary event.

Seismic waves generated by tornadoes when they touch down could be used to measure a twister’s intensity, according to a new study that examined the May 2011 Joplin tornado. The findings could open the door to devising more accurate methods to study tornadoes from the ground.
