The Earth is a dynamic system where the atmosphere, biosphere, cryosphere, hydrosphere, and lithosphere are coupled. The concept that events occurring in one sphere influence another has important implications for how geoscientists view global and regional scale processes. Through a lens of integrated Global Change, researchers in the Department of Earth Sciences conduct cutting edge, interdisciplinary research on both ancient and modern environments to address the complexity of natural systems and anthropogenic perturbations.

Research Focus Areas

Students develop research topics with a goal to produce publishable results from their MS thesis or PhD dissertation within one, or across several of the following focus areas.

  • Climate Systems Dynamics

    Our program conducts interdisciplinary scientific research that characterizes and models the fundamental dynamics of the climate system over a range of times scales in order to understand rates and processes of environmental change. The integration of geological archives, modern observational studies, and modeling experiments allow us to capture scenarios that incorporate full-system feedbacks. Recent and ongoing research includes:

    • Reconstructing a record of water availability, vegetation, and moisture sources in the Searles and Death Valley basins of the southwestern USA spanning the last 150,000 years.
    • Integration of continental records of climate dynamics, river and landscape evolution, and tectonics preserved in the Eocene Green River Formation from an episode of unusually warm climate called the Early Eocene Climatic Optimum (EECO). This study aims to better understand how the Earth system will respond to rising temperatures in the future.
    • Development of atmospheric CO2 proxies from lacustrine evaporite deposits.
    • Characterization of ancient seawater trapped in fluid inclusions in Phanerozoic marine halite.
    • Understanding Antarctic Ice Sheet dynamics and Southern Ocean processes using marine sedimentary archives from the International Ocean Discovery Program Expedition 374.
    • Exploring Antarctica’s subglacial environment through the Subglacial Antarctic Lakes Scientific Access (SALSA) project.
    • Investigating paleoceanographic and paleoclimatic change during past warm periods.
    • Reconstruction of the Pacific Ocean Kuroshio Current Extension and its response to late Neogene climate and tectonic events using stable isotopic analyses, microfossil data, and sedimentologic proxies.
    • Characterizing sea surface conditions within the Tasman Sea across the Miocene Climate Optimum using a multi-proxy approach.
    • Combining sedimentology with x-ray fluorescence spectroscopy to understand the depositional, paleo water conditions, and tectonic histories recorded by thick marine and lacustrine mudstone sequences.
    • Sedimentary facies analysis, geochemistry, and palynology of Quaternary river terraces in New York State.
  • Modern and Ancient Life

    The multibillion-year record of life on Earth has been shaped by extrinsic, abiotic, and biotic interactions. Our program investigates the history of life at the cellular to macro-scales to assess how it has been impacted by environmental change and major climatic shifts, and how microbial life interacts with the hydrosphere, lithosphere, and atmosphere. Recent and ongoing research includes:

    • Geomicrobiological cycling of environmentally relevant trace metal(loids) such as As, Sb, Se, Cr and U in freshwater and under conditions of extreme salinity, temperature, alkalinity, and anoxia.
    • Aquatic food web behavior of biologically sensitive elements such as As, Sb, and Se.
    • Long term survival of microorganisms in fluid inclusions in halite. Microorganisms (bacteria-archaea-algae) form tiny ecosystems in fluid inclusion droplets that allow some archaea to survive in a state of starvation survival for tens of thousands of years.
    • Paleobiogeographic modeling of early Paleozoic shallow marine invertebrates (e.g., brachiopods, trilobites, echinoderms) across major biotic (e.g., the Great Ordovician Biodiversification Event and Late Ordovician mass extinctions) and climate events
    • Constraining the environmental conditions under which some of the earliest forest ecosystems (circa 370 Ma) were developed.
    • Paleobiogeography of Neogene planktic foraminifera and dispersal patterns related to the development of modern surface ocean circulation patterns
    • Understanding the role of cyanobacterial blooms in calcium carbonate whiting events and the influence of biotic and abiotic factors in microbialite formation in Fayetteville Green Lake, NY.
    • Characterizing patterns in regional planktic foraminiferal latitudinal diversity gradients related to western boundary currents through the Cenozoic and linking regional patterns to regional paleoceanographic proxies to infer drivers of local diversity.
    • Understanding how micro-organisms impact trace metal cycling in landfills and hazardous waste disposal sites.
  • Natural Resources

    Society depends on the use of renewable and non-renewable natural resources including fresh water, earth materials, and energy resources. One of the most fundamental interactions within the Earth system is between water and minerals. The interaction of water with silicate minerals influences such things as the formation of hydrous minerals at Earth’s surface, the formation of soils, the extent of water storage in the lithosphere, and the production of magma by dehydration of crustal rocks in subduction zones. Our program studies the formation mechanism, temporal change, and distribution of natural resources and their interaction with the hydrosphere within the context of the Earth system. This is done through field study, laboratory characterization, and experimental methods. Recent and ongoing research includes:

    • The study of crystal-chemical controls that allow chlorine to substitute for hydroxyls in calcium amphiboles with implications for seawater-rock interactions as well as economic-deposit formation.
    • An experimental study of the upper-thermal stability of glaucophane ± zoisite or paragonite breaking down to form jadeite (or omphacite) and garnet to determine the conditions at which blueschist-facies metamorphic rocks convert to eclogite-facies rocks in subduction zones.
    • Experimental determination of the reaction of the feldspathoid mineral nepheline with NaCl-brines to develop a paleo-chlorinity and/or geobarometer for sodalite-bearing rocks.
    • Computer modeling of sedimentary basin subsidence to understand the fundamental controls on sedimentary facies distributions, including source rocks, and their burial histories.
    • Using elemental concentration data coupled with statistical models from marine, fluvial, and lacustrine mudstones to examine the utility and variability of potential proxies for TOC, paleoredox conditions, and sediment provenance. 
    • Exploring the use of analytical techniques including the use of laser ablation ICP-MS to understand mineral formation and weathering processes.
    • Field and analytical study of Pleistocene volcanism in the Chilean volcanic belt to understand the processes of mantle hydration and element mobilization during and after periods of flat slab subduction.
    • A field, analytical, and computer modeling study of crystallization in mafic sills to examine the processes of differentiation, element distribution, and ore deposit formation in igneous magma chambers.
    • Field and analytical study of massive iron-ore deposits to separate the results of magmatic processes from the results of hydrothermal processes.
  • Geophysics and Remote Sensing

    Characterization of the surface and shallow subsurface through geophysical and remote sensing techniques, as well as, seismic imaging of the deep crust and upper mantle have been critical to advance our understanding of the Earth system. Recent technological advances in high-quality, low cost sensors and acquisition platforms have revolutionized this research area. Recent and ongoing research includes:

    • Detection of unexploded plastic land mines using drone-based thermal imagery.
    • Locating abandoned oil and gas wells using high precision magnetometry on a hybrid gas/electric aerial drone.
    • Designing rapid deployment broad band seismic arrays to detect induced seismicity from hydraulic fracture operations.
    • Passive-source seismic investigation of the Central Chile subduction zone.
    • Mapping modern depositional environments in freshwater and saline lakes using a submersible ROV and water chemistry sensors.
  • Natural Hazards and Environmental Remediation

    With our increased recognition of the interconnection of Earth system and human activity the task of geological hazard and environmental contamination assessment, mitigation, and preparedness has come into sharp focus. Modern geoscientists work at the intersection between societal need for a safe habitat and sustainable use of natural resources with the reality of rapidly growing population expansion into geologically and environmentally hazardous areas. Recent and ongoing research includes:

    • Documenting the massive formation of salt occurring in the Dead Sea as a response to the ongoing hydrological crisis within the framework of well-known climate conditions and anthropogenic factors.
    • Exploring the use of lichen as passive air-quality monitors in both the Binghamton University Nature Preserve and other urban areas as well as in the Athabasca Oil Sands Region (Alberta, CA).
    • Assessing the effects of roadway pollutants (deicers, heavy metals, etc.) on constructed wetlands and their efficacy of pollution mitigation.
    • Analyzing the effects of pollutants such as road salt and a common agricultural antibiotic (sulfamethoxazole) on the nitrogen cycle with implications on nitrogen pollution in regions such as (but not limited to) the Chesapeake Bay watershed.
    • Monitoring ecosystem-scale processes in urban, rural, and mixed land use environments within the Upper Susquehanna River watershed.
    • Biogeochemistry of arsenic and humic substances in the Blackfoot Disease endemic area of Taiwan.
    • Arsenic contamination of groundwater in the Bengal Delta plain and the role of microorganisms.
    • Changes in flood frequency in the context of changing climate.
    • Historical changes in stream patterns and erosion in watersheds in the Catskill Mountains of New York bin both dammed and undammed watersheds.
    • Detecting harmful algae blooms in freshwater lakes using satellite and drone-based imagery.

  • Department Policies on Use of Equipment

    The facilities and equipment of the department that are used principally for instruction are available also for student research in most cases. Use of facilities and equipment implies acceptance of responsibility for replacement or repair in the event of damage or loss. Specialized research equipment is accessible only with permission from the faculty member or technical staff in charge. Some specific examples are set out below.

    A. Equipment
    With few exceptions, departmental equipment may not be removed from the building, nor transferred from one student to another.

    1. Keys - Students may have one key for their assigned office and one for the outside building door. These must be signed for in the department office or from the building supervisor, and must be returned when a student vacates his/her office space, or when a prolonged absence is anticipated. A refundable fee is assessed at the time of key check-out. Short-term key loans for other facilities are available with permission from the faculty/staff in charge of that facility. Such keys must be signed for and returned when the specific task has been completed.
    2. Computers - Computers are scattered throughout the department. Some are dedicated to specific areas, e.g. analytical equipment, seismology, etc.. Others are available for general analytical, word-processing, and e-mail use in room 262C. Research and e-mail accounts can be established through the department office. The computer PODs in the Computer Center, Science 2, and Science 3 have a large number of micros, terminals, and laser printers for general use. Academic Support in the computer center gives short-courses on the use of micros, word-processing, e-mail, internet access, etc. The Science Library has workstations for Internet access for bibliographic searches and other information retrieval. Binghamton University's GIS Core Facility can provide support for projects requiring use of GIS for spatial analysis of data.
    3. Research Facilities - The Department has extensive analytical research facilities. Equipment includes two heating-freezing microscopes with video recording capabilities for fluid inclusion studies; a recirculating flume for experiments in sediment transport; an experimental petrology laboratory with various high-pressure and high-temperature equipment; a paleomagnetism laboratory; a seismology laboratory with computer workstations, a local seismograph station, and shallow seismic exploration equipment; a Dionex ICS-2000 ion chromatograph; two scanning electron microscopes; a DCP-atomic emission spectrometer and a Varian Vista-MPX ICP-optical emission spectrometer for whole-rock and mineral-separate analyses; an ICP-mass spectrometer for trace element analysis; a JEOL-8900 electron microprobe; a Philips automated X-ray diffractometer; GPS surveying equipment; stereoscopes and a zoom transfer scope for study of aerial photographs. Permission to use equipment must be obtained from appropriate faculty and/or technical staff.
    4. Brunton Compasses - The Department has a small number of Bruntons to support field courses. These may be borrowed for limited periods, provided they are returned at a predetermined date, in good condition. Since Bruntons are basic tools for geologists, students should obtain their own for extended summer thesis/dissertation work. Arrangements for short-term loans only can be made with the department secretary.
    5. Microscopes - Student microscopes, stored in Room 254, may be used there but not borrowed or removed. Research microscopes are available elsewhere; make inquiries with the appropriate faculty supervisor.
    6. Thin-section Supplies - Because of the difficulty for students in securing thin-section supplies, these are normally provided by the department. Faculty will provide such supplies through research grants where large quantities are involved. Supplies and instruction in their use will be provided by staff in charge of the thin-section/rock preparation laboratory.
    7. Department Vehicles - These are intended for field trips in instructional support. Students may obtain limited short-term use of vans on a stand-by basis, always with the understanding that instructional needs come first, sometimes on short notice. Department vehicles may not be used for personal purposes. Department vehicles may only be driven by students with a valid N.Y. State driving license and holding research or teaching assistantships.
    8. Other - Other items of research and instructional equipment occasionally can be loaned, with approval by and with supervision of the faculty or staff in charge.
