Geological Sciences Degree Programs

The University of Delaware’s Department of Earth Sciences (ES) prepares students for their future by exposing them to exciting opportunities through education and research in the classroom, the laboratory and the field.
Our graduates go on to fulfilling careers in environmental consulting firms, the energy industry, governmental regulatory agencies, earth science teaching and research in the geological sciences. ES programs feature small classes with hands-on field and laboratory-based instruction delivered by an internationally respected, research-active faculty.
Graduate Degree Programs
In any graduate program, a student’s advisor provides mentorship and guidance while filling crucial practical roles in their education as well. Success in either a master’s or Ph.D. program requires a student to find a faculty member with an established record of scholarship in the specific research field the student wishes to investigate. Use this categorization of the department’s faculty to help find good potential matches for an advisor.
In geomicrobiology, the work is multidisciplinary, combining geochemical field characterization and sampling, molecular biology, biochemistry, microbiology and a wide variety of microscopy and spectroscopy techniques to study how microorganisms affect environmental chemistry and how chemistry selects for and influences the evolution of life. Research in environmental geochemistry includes investigations of the mechanisms of carbonate nucleation/growth and the influence of organic templates and living interfaces on these processes, unraveling the biogeochemical behavior of radiogenic isotope and rare earth element concentrations in the modern ocean, studying submarine groundwater discharge and associated chemical fluxes, and developing and applying new methods in isotope geochemistry and in synchrotron radiation studies of mineral-fluid interactions.

Earth Sciences faculty and their students combine field work, lab studies, and numerical modeling to research groundwater flow, fluvial geomorphology, and modifications to Earth’s surface as a result of changes in climate and human activities. Areas of study include: coastal groundwater dynamics, groundwater-surface water interaction, groundwater flow and solute transport modeling, geostatistical modeling of subsurface heterogeneity, hydro-economics, effects of dams and dam removal on rivers, novel methods for measuring and modeling river bank erosion, and more.

Our faculty and their students examine samples of peridotite – the main rock of the upper mantle – and use seismology – the study of the passage of waves generated by earthquakes and other sources – to examine modern surface deformation and the physical and chemical processes, mechanisms and driving forces that govern plate tectonics. Their research investigates the role of the mantle in the plate tectonic cycle, from the generation of lithospheric plates at ocean ridges to their destruction at subduction zones, as well as the flow that occurs within the convecting interior of the Earth.
They also use a variety of high-resolution geophysical techniques including ground penetrating radar, side-scan sonar, shallow seismic reflection, and geoelectrical techniques to study Quaternary stratigraphy, integrated biogeophysical systems, and coastal, estuarine, and riverine benthic habitats.
