Variable Mantle Lies Below Ancient Pieces of Earth's Crust

by C. Sullivan 16 March 20162 March 2023

Underneath old and stable pieces of Earth's crust in North America, the mantle's uppermost portion contains multiple layers that change the velocities of seismic waves.

The North Atlantic Ocean's Missing Heat Is Found in Its Depths

by C. Sullivan 3 March 201612 January 2022

In the 2000s, the North Atlantic stopped absorbing as much atmospheric warmth. However, the ocean lost only a little heat—the rest was held deeper below the surface by altered circulation patterns.

Unknown Tsunami Trigger Hides Along a Creeping Aleutian Fault

by C. Sullivan 3 March 201624 January 2023

A seismically quiet part of the Aleutian Subduction Zone may have caused tsunamis in the past—and may cause future tsunamis that could travel across the Pacific Ocean.

Characterizing Interglacial Periods over the Past 800,000 Years

by C. Sullivan 2 March 201628 September 2021

Researchers identified 11 different interglacial periods over the past 800,000 years, but the interglacial period we are experiencing now may last an exceptionally long time.

Fewer Tropical Cyclones Form After Volcanic Eruptions

by C. Sullivan 24 February 201617 November 2022

Volcanic eruptions aren't all bad—in some cases, they can lower the frequency of tropical cyclones in the North Atlantic by emitting sulfate aerosols.

Climate Change Freezes Mountain Wildflower Reproduction

by C. Sullivan 22 February 20164 November 2022

New research provides evidence that plants that flower earlier in the year because of climate warming experience more frost damage and have less reproductive success.

Deep-Sea Microbes Can Leave Records of the Past

by C. Sullivan 9 February 201614 March 2023

Researchers use carbon signatures within sea sediments to identify microbial activity and also to date earthquakes.

The Forgotten Water Vapor at High Altitudes

by C. Sullivan 5 February 201629 March 2022

Scientists find that estimations of high-altitude atmospheric water, critical for the greenhouse effect, are not as accurate as previously thought.

Mercury in Rain Increasing in Western and Central United States

by C. Sullivan 2 February 201613 March 2023

Despite tightening emissions rules, mercury concentrations are rising in rainfall wetting western and central regions of the United States. The pollutant may waft in from Asia, scientists speculate.
