Tyler Hall
Ph.D. Student in Geological Sciences
BioI am a PhD student interested in the quantification of subsurface uncertainty, with four years of experience at Freeport-McMoRan's copper mine at Bagdad, Arizona.
My research questions include: How do scientists, engineers, and investors interpret and understand the uncertainty associated with the geologic model? How can implicit modeling be used to quantify uncertainty? Do subsurface resources require a different philosophical approach to financial analysis, since much of their value is dependent on geologic modelling? -

John A. Harrison
Visiting Professor, Earth System Science
BioDue largely to human activities associated with food and energy production, the world is experiencing an un-precedented mobilization of nutrients such as nitrogen (N) and phosphorus (P). A substantial portion of this mobilized N and P flows into streams and rivers, and eventually down to coastal waters, where nutrient over-enrichment has been associated with a host of environmental impacts. En route to the ocean, these nutrients can alter ecosystem function as well as the balance of atmospheric greenhouse gases.
I use experimental and spatially explicit modeling approaches to elucidate processes governing the mobilization, transport, transformation, and ecosystem/biogeochemical impacts of land-based N, P, and other bio-active elements.

BioThomas Hayden is Director of the Master of Arts in Earth Systems, Environmental Communication Program at Stanford University. He teaches science and environmental communication and journalism in Stanford's School of Earth, Energy & Environmental Sciences and Graduate Program in Journalism. He came to Stanford in 2008, following a career of reporting and writing about science and environmental issues for national and international publications.
Hayden’s journalism career began at Newsweek magazine in New York, where he was an American Association for the Advancement of Science Mass Media fellow in 1997. In 2000, he moved to US News & World Report in Washington, DC, where he covered science, the environment, medicine, culture and breaking news as a senior writer. Since 2005, Hayden has been a freelance journalist. His cover stories have appeared in publications including Wired, Smithsonian, National Geographic, Washington Post Book World and many others. He has reported from South America, Europe, and Asia; and North America from New Orleans to the Canadian Arctic.
Hayden is coauthor of two books. He wrote the 2007 national bestseller On Call in Hell, about battlefield medicine in Iraq, with Navy doctor Richard Jadick. In 2008 he collaborated on the critically acclaimed Sex and War, about the biological evolution and cultural development of warfare through human history, with Malcolm Potts of the University of California, Berkeley. He was the lead writer on the 2010 9th revision of the iconic National Geographic Atlas of the World. And he was coeditor of and a contributor to The Science Writers' Handbook: Everything You Need to Know to Pitch, Publish and Prosper in the Digital Age, published in 2013.
In 2005, Hayden taught science writing in The Writing Workshops at Johns Hopkins University in Baltimore with his wife and fellow science journalist, Erika Check Hayden. He was a founding faculty member in the annual Banff Centre Science Communications workshop, where he taught from 2006 until 2010, and was involved as a speaker and trainer with the Leopold Leadership Program for environmental scientists from 2000 to 2013.
Hayden graduated from his hometown school, the University of Saskatchewan, with a Bachelor of Science in Agriculture (honours) degree in applied microbiology and food science, and received an MS degree in marine biology from the University of Southern California. He completed five years of doctoral study in biological oceanography at USC, before leaving science for journalism with A.B.D. status. He spent more than nine months at sea cumulatively over five years, conducting oceanographic research from Southern California to San Francisco Bay, and from Antarctica to Easter Island.
In 2015, Hayden helped launch a new graduate degree program in Stanford's School of Earth, Energy & Environmental Sciences. The Master of Arts in Earth Systems, Environmental Communication degree is focussed on the study and practice of effective, engaging, accurate communication of complex environmental and Earth systems information to nonspecialist audiences. -
Andrew Hennig
Ph.D. Student in Earth System Science
BioAntarctic ice sheet, both of which have exhibited significant mass loss over the past few decades. If the two ice sheets were to fully collapse, they could be responsible for up to 15m of global sea level rise (roughly equal parts from both). This sea level rise would not only pose serious problems for coastal settlements, but cause serious changes to ecosystems, and could profoundly alter the Earth’s ocean circulation.
Current estimates of the mass balance for ice sheets are based primarily on satellite data. This data has become more accurate and more available than ever before, since the 1990s. While estimates can be provided by satellite data, satellites are limited by virtue of the fact that they can only evaluate the surface of the ice shelf. Recent research has shown that a significant amount of the mass loss from the West Antarctic ice sheet is happening underwater, along grounding lines, where deep waters, warmed by global warming, enter the area underneath the ice shelf, and melt the shelves from the bottom. This not only results in mass loss directly, but increases calving of glaciers into the ocean, further accelerating their loss. This melting, below the surface of the ice shelves, cannot be estimated by satellites.
To get a better understanding of the impact of warmer deep waters on glacial retreat in Western Antarctica, we need to measure the melt more directly. Using highly precise measurements of salinity and isotopic composition of seawater in coastal regions of Western Antarctica, we can estimate the amount of glacial meltwater present in the oceanic adjacent to ice sheets. Gaining a greater understanding of the rates and locations of West Antarctic melting will be crucial to developing our understanding of future sea level rise, and other wider impacts. -

Carl Hoiland
Visiting Scholar, Department of Geological Sciences
BioI am broadly interested in regional tectonics, crustal evolution, global paleogeography, and the nature of orogenesis. My research is informed by a variety of techniques, including structural geology, mapping (i.e. spatial data visualization), geochronology, metamorphic petrology, thermochronology, thermobarometry, isotope geochemistry, and geophysical datasets.
In the western US Cordillera, my research focuses on the interplay between crustal thickening, geothermal gradients, magmatism, and extension in the orogenic hinterland. Much of this work has centered around field studies in the northern Snake Range metamorphic core complex of Nevada, which offers a unique glimpse as to processes operative in the upper, middle, and lower crust during mountain building.
In the Alaskan Cordillera, my research focuses on the long-term paleogeographic and tectonic evolution of the northernmost Cordillera (Brooks Range and Arctic Alaska). One such effort is an attempt to better understand a major post-Caledonian plate reorganization that led to subduction initiation on the then-passive Laurussian margin, followed by backarc rifting and translation of "exotic" crustal terranes southward into the western US Cordillera. -
