Hot spot at Hawaii? Not so fast

MIKE WILLIAMS – AUGUST 18, 2017 Hot spot at Hawaii? Not so fast Rice University scientists’ model shows global mantle plumes don’t move as quickly as thought HOUSTON – (Aug. 18, 2017) – Through analysis of volcanic tracks, Rice University geophysicists have concluded that hot spots like those that formed the Hawaiian Islands aren’t moving as […]

Data mining finds more than expected beneath Andean Plateau

JADE BOYD – AUGUST 23, 2017 Seismic data suggests means of producing massive volumes of continental crust Seismologists investigating how Earth forms new continental crust have compiled more than 20 years of seismic data from a wide swath of South America’s Andean Plateau and determined that processes there have produced far more continental rock than previously […]

Hidden river once flowed beneath Antarctic ice

Rice U. study: Flowing water influenced retreat of ancient Antarctic ice sheet JADE BOYD AUGUST 21, 2017 Antarctic researchers from Rice University have discovered one of nature’s supreme ironies: On Earth’s driest, coldest continent, where surface water rarely exists, flowing liquid water below the ice appears to play a pivotal role in determining the fate […]

New plate adds plot twist to ancient tectonic tale

Rice University scientists say Malpelo microplate helps resolve geological misfit under Pacific Ocean By Mike Williams713-348-6728mikewilliams@rice.edu HOUSTON – (Aug. 14, 2017) – A microplate discovered off the west coast of Ecuador adds another piece to Earth’s tectonic puzzle, according to Rice University scientists. Researchers led by Rice geophysicist Richard Gordon discovered the microplate, which they have named […]

Regional background O3 and NOx in the Houston–Galveston–Brazoria (TX) region: a decadal-scale perspective

Loredana G. Suciu1, Robert J. Griffin2, and Caroline A. Masiello11Department of Earth Science, Rice University, Houston, 77005, USA 2Department of Civil and Environmental Engineering, Rice University, Houston, 77005, USA Abstract. Ozone (O3) in the lower troposphere is harmful to people and plants, particularly during summer, when photochemistry is most active and higher temperatures favor local chemistry.

Glaciers may have helped warm Earth

Glaciers may have helped warm Earth MIKE WILLIAMS July 31, 2017 Rice professor’s study details effect of glacial versus nonglacial weathering on carbon cycle It seems counterintuitive, but over the eons, glaciers may have made Earth warmer, according to a Rice University professor. Weathering of Earth by glaciers may have warmed Earth over eons by […]

Biochar could clear the air in more ways than one

New research by Professor Carrie Masiello’s Post-Doctoral Fellow Ghasideh Pourhashem is highlighted.   “I really like her team’s work because it models a couple of important parts of environmental science – the fundamental team nature of problem-solving (her team’s work required integrating soil science, air quality, and health economics), and then also the idea that addressing […]

Seismic CT scan points to rapid uplift of Southern Tibet

  JUNE 7, 2017 By Jade Boyd Tomographic model indicates Southern Tibet formed within 10 million years   HOUSTON — (June 7, 2017) — Using seismic data and supercomputers, Rice University geophysicists have conducted a massive seismic CT scan of the upper mantle beneath the Tibetan Plateau and concluded that the southern half of the “Roof […]
