(l-r) Jonny Wu, assistant professor of geology in the UH Department of Earth and Atmospheric Sciences and Spencer Fuston, a third-year geology doctoral student, applied a technique developed by the UH Center for Tectonics and Tomography called slab unfolding to reconstruct what tectonic plates in the Pacific Ocean looked like […]

Climate scientists Nicholas Balascio and Francois Lapointe working with an ice auger to drill in the 3.5m thick ice at South Sawtooth Lake, Ellesmere Island, Nunavut Territory, Canada. An ice auger extension is needed because the ice is so thick. Coring lake sediments can only be done after this tedious […]

This data image shows the monthly average sea surface temperature for May 2015. Between 2013 and 2016, a large mass of unusually warm ocean water – nicknamed the Blob – dominated the North Pacific, indicated here by red, pink, and yellow colors signifying temperatures as much as three degrees Celsius […]

An artist’s rendering of undersea earthquake waves.

The method, which they tested in the East Indian Ocean and where they uncovered a decadal […]

The prevailing theory has been that sea ice can act as a lid to keep carbon in the ocean from escaping back to the atmosphere. However, researchers at MIT have now identified a counteracting effect that suggests Antarctic sea ice may not be as powerful a control on the global […]

The CENOGRID shows Earth has experienced four distinct climate states over the last 66 million years. The detailed climatic changes of the past can be studied like a colorful barcode and provide context for ongoing anthropogenic change and how exceptional it is. Earth’s climate has gradually cooled for the last […]

The reef at North Rock, Bermuda, similar to the reef (Sea Venture Shoals) where coral fragments were collected for this study. Credit: Stacy Peltier New research shows that pulses of cooler deep water reduced heat stress responses in corals. The risk of severe coral bleaching—a condition in which corals lose […]

Animation Earth’s oceans help to slow global warming by absorbing carbon from our atmosphere – but fully observing this crucial process in the upper ocean and lower atmosphere is difficult, as measurements are taken not where it occurs, the sea surface, but several meters below. New research uses data from […]
