I am a seismologist, and my research is focused on imaging the Earth's interior using seismic waves. The overarching goal of my research program is to determine 3-D variations in the temperature, composition, partial-melt content, and volatile abundance of Earth’s mantle.
Conversations about sea-level rise often spotlight warming temperatures. But Earth’s geological engine quietly plays its own role. Professor Colleen Dalton, together with colleagues, connects the dramatic change in sea levels to a slowdown in seafloor spreading that reshaped the depth of the ocean basins.
A new study by DEEPS Professors Colleen Dalton, Chris Huber, Tim Herbert, and Senior Research Associate Weimin Si explores how variations in global mean sea level over millions of years originate from changes in both the climate and solid Earth systems.
The “Solid Earth Geophysics” class joined the North Burial Ground for a groundbreaking project this Halloween season, using ground penetrating radar (GPR) to help investigate the mysteries buried within the historic cemetery.
A recent Eos Editors Highlight, titled "Can Anelastic Attenuation of Oceanic Mantle be Reliably Measured?" features research by Postdoc Joshua Russell and Associate Professor Colleen Dalton.
