Criss has championed the Mississippi, Missouri and Meramec rivers, among others, in more than 25 years of work in earth and planetary sciences at Washington University in St. Louis.
The Earth has been through a lot of changes in its 4.5 billion year history, including a shift to start incorporating and retaining volatile compounds from the atmosphere in the mantle before spewing them out again through volcanic eruptions.
What ‘warm and wet’ planetary history means for prospects of life on Mars
When Opportunity’s 5000th day dawned in February, it was a meaningful milestone for the team, and it led to a personal first for the veteran robot field geologist that has chalked up so many firsts she’s set the standard for Mars rovers.
“To understand America at this time,” says R.D. James, a Missouri farmer and new Army assistant secretary overseeing its Corps of Engineers, “you have to understand the river.”

Dr. Ghassan Aleqabi and Dr. Michael Wysession, Seismologists in Washington University in St. Louis, investigates enemy attacks, terrorism and nuclear tests by seismic sleuthing.
Tonga is a seismologists’ paradise, and not just because of the white-sand beaches. The subduction zone off the east coast of the archipelago racks up more intermediate-depth and deep earthquakes than any other subduction zone, where one plate of Earth’s lithosphere dives under another, on the planet.
Bradley Jolliff, a professor of earth and planetary sciences at Washington University in St. Louis, and the leader of the proposed MoonRise mission, commented on his team's proposal for a NASA mission to go back to the moon's unexplored far side.

William McKinnon, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis and a co-author on two of four new Pluto studies published Dec. 1 in Nature, argues that beneath the heart-shaped region on Pluto known as Sputnik Planitia there lies an ocean laden with ammonia.
Michael Wysession, professor of earth and planetary sciences at Washington University in St. Louis, explains why there are volcanoes on Madagascar, an island that isn’t near any tectonic boundaries.
Dr. Bill McKinnon of Washington University suspected a liquid ocean beneath the surface of Pluto, published remarkable findings about Pluto that surpassed expectations about the dwarf planet and explained how a large section of Pluto’s nitrogen ice surface is renewed by a process called convection.
William McKinnon of Washington University has a long career as a planetary scientist that has been marked by a series of exciting discoveries and new explorations.
Doug Wiens, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, and Weisen Shen, a postdoctoral research associate with Wiens, installed a seismometer to investigate the Midcontinent Rift and presented seismic images of the rift at the annual meeting of the Geological Society of America (GSA) Sept. 25-28.
Raymond Arvidson, earth and planetary science professor at Washington University in St. Louis, received the Lester W. Strock Award, which is given by the New England Section of the Society of Applied Spectroscopy in recognition of a selected publication of substantive research in/or application of analytical atomic spectrochemistry in the fields of earth science, life sciences, or stellar and cosmic sciences.
Kun Wang, assistant professor in Earth and Planetary Sciences in Arts & Sciences at Washington University in St. Louis, reported isotopic differences between lunar and terrestrial rocks that provide the first experimental evidence that can discriminate between the two leading models for the moon’s origin.
Martin J. Pratt, research scientist having recently completed my PhD at Washington University in St. Louis, software developer for the Fossett Laboratory for Virtual Planetary Exploration at WashU, embraced augmented reality platforms in order to display complex concepts within the Earth Sciences.
Bruce Fegley and Katharina Lodders-Fegley, respectively professor and research professor in earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, published models of the chemistry of a steam atmosphere in equilibrium with a magma ocean at various temperatures and pressures, which provided some suggestions for planet hunters.
Washington University geologists mapped the huge, branching drainage system that underlies the plain that is called Fogelpole Cave, located just below the notch in the west side of Illinois, where Mississippian limestones are exposed at the surface.

Robert Criss, PhD, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, says there is more to the flood than the rain.
