Ocean World

picture of Kevin Hand

Dr. Kevin P. Hand is a planetary scientist/astrobiologist at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. His work involves numerical, laboratory, and field research on the physics and chemistry of ocean worlds in our solar system. Dr. Hand is a Deputy Project Scientist for NASA’s Europa Mission, leading the pre-Phase-A Europa lander mission concept, and co-chairing the Europa Lander Science Definition Team. From 2011-2016 Hand served as Deputy Chief Scientist for Solar System Exploration at JPL. He is a member of the National Research Council’s Committee on Astrobiology and Planetary Sciences. His work has brought him to the Dry Valleys of Antarctica, the depths of the Earth’s oceans, and to the glaciers of Kilimanjaro and Mt. Kenya. Dr. Hand was a scientist onboard James Cameron’s 2012 dive to the bottom of the Mariana Trench, and he was part of a 2003 IMAX expedition to hydrothermal vents in the Atlantic and Pacific oceans. He has made nine dives to the bottom of the ocean and has been featured in several National Geographic, BBC, and Discovery Channel documentaries. In 2011 he was selected as a National Geographic Emerging Explorer. Hand earned his PhD from Stanford University (and was a visiting scholar in Princeton’s astrophysics department) and he earned bachelors degrees from Dartmouth College. He was born and raised in Manchester, Vermont.

Dr. Julie Huber

is an oceanographer by training and is broadly interested in how basic earth processes- rocks forming, fluids moving, sediments accumulating- interact to create and maintain life in the oceans. Her research addresses some of the most central questions about the nature and extent of microbial life on Earth in one of its least explored corners, the subseafloor habitat beneath the ocean floor. Julie received her B.S in Marine Science from Eckerd College in 1998 and her Ph.D. from the University of Washington in 2004. In 2007, she received the L’Oréal USA Fellowship for Women in Science. Beyond her duties as an Associate Scientist in Marine Chemistry and Geochemistry at Woods Hole Oceanographic Institution, Julie also serves as the Associate Director of the NSF Science and Technology Center for Dark Energy Biosphere Investigations (C-DEBI), whose mission is to explore life beneath the seafloor and make transformative discoveries that advance science, benefit society, and inform and inspire the general public about discoveries in ocean sciences and related disciplines. You can find her on twitter @julesdeep.

picture of Everett Shock

Dr. Everett Shock grew up in the heart of Orange County, California, two miles from Disneyland. He received his BS in Earth Sciences at UC Santa Cruz, where he met his wife Allison. After working for a couple years at the US Geological Survey he entered grad school at UC Berkeley where he earned his PhD in Geology. He taught at Washington University in St Louis for 15 years before moving to Arizona State University. Research by Shock and his students converges on understanding how planets become habitable through fieldwork in extreme environments, hydrothermal experiments, and thermodynamic interpretations of planetary geochemical processes. Their fieldwork in hydrothermal ecosystems and regions of active serpentinization take them to Yellowstone and Oman, and their efforts to quantify habitability take them to sub-glacial, cold-spring and acid mine drainage as well. Back in the lab they integrate water, gas, mineral, and microbial samples to gain compositional constraints on Earth microbiomes, place genetic sequencing data in their geochemical context, and test the reactivity of organic compounds and minerals in hydrothermal experiments. Thermodynamic data, lab experiments, and field results all influence their theoretical models of energy and power supply to microbiomes during weathering and hydrothermal alteration processes on Earth, asteroids, and Ocean Worlds. Shock is a member of NASA’s Europa Clipper mission through the science team for the MASPEX mass spectrometer.

picture of Krista Soderlund

Dr. Krista Soderlund is a planetary geophysicist broadly interested in fluid dynamic processes. She is a Research Associate at the University of Texas Institute for Geophysics (UTIG), previously earning dual B.S. degrees in Physics and Space Sciences from the Florida Institute of Technology in 2005 and a Ph.D. in Geophysics and Space Physics from the University of California, Los Angeles in 2011. Her recent projects use numerical models to investigate the origin of the Moon’s magnetic field, simulate convection and magnetic field generation within the interiors of Uranus and Neptune, and understand icy satellite geodynamics with an emphasis on Europa and Enceladus. Soderlund is also a science team member of the ice-penetrating radar instrument (REASON) selected for the upcoming Europa Clipper mission and served recently on NASA's Ice Giant Mission Study Science Definition Team.

The Annual Donnel Foster Hewett Lecture Series is sponsored by the Department of Earth and Environmental Sciences and is supported by a bequest which was made to the department by one of its most distinguished alumni, Donnel Foster Hewett (more info).

Hewett matriculated at Lehigh University in September 1898. Following graduation in 1902, he spent another year at Lehigh as an assistant in metallurgy and mineralogy under the direction of Joseph Barrell. After Joseph Barrell moved to the Department of Geology at Yale in 1907, Hewett went there in 1909 to study geology and received his Ph.D.

In 1911, he joined the U.S. Geological Survey and his career with the organization spanned 60 years until his death in 1971. When in 1951, Donnel Foster Hewett reached the mandatory retirement age of 70, his full-time employment by the Survey was continued indefinitely by Presidential order. To a great host of geologists, he became a legend in his own time and was affectionately referred to as "Mr. Geological Survey" or "Mr. Manganese", the latter because of his devotion to and advancement of our understanding of the mineralogy and genesis of manganese ores.

During his career he received many honors:

  • Vice President, Geological Society of America in 1935 and 1945
  • President of the Society of Economic Geologists in 1936
  • Elected to the National Academy of Sciences in 1937 and the Academy of Arts and Sciences in 1949
  • Distinguished Medal of the Department of the Interior in 1951
  • Penrose Medal in 1964
  • Honorary Ph.D. from Lehigh in 1942
