    Broadly speaking, my research involves the interaction of ice sheets, oceans and the climate system on orbital to centennial time-scales. I currently have projects working on the Laurentide, Antarctic and Greenland ice sheets addressing the behavior of these ice sheets and their effects on climate over multiple glacial cycles. I am also beginning work into documenting the natural volatility of the Arctic cryosphere outside of the Greenland ice sheet. My approach to research uses a combination of dating methods (cosmogenic dating, radiocarbon), analytical techniques (isotope and trace element analysis, geochemistry), field geology, and conceptual and analytical models. I believe a holistic approach is required to place data into the global picture and vice versa for the applicability of models.

    Fisheries oceanography, spatial ecology, fish early life stages, statistical analysis of catch and survey data
    My primary research focus is on fisheries oceanography and marine ecology. I study the causes of temporal and spatial variation of marine populations, as well as the management implications of the factors involved. A substantial fraction of my work revolves around early life stages of fish, as in marine organisms, spatial and temporal variability at the population level is closely linked to events that occur during the very first few months or years of life. I have also worked extensively on the ecology of adult stages, predator-prey trophic interactions in marine ecosystems, and on dispersal and distribution patterns of scyphozoa jellyfish. I particularly value merging the ecological and quantitative disciplines to study processes that affect the dynamics of marine populations in space and time. Thus, I work with modelers, statisticians, and fisheries biologists from both academic and management institutions to tackle practical problems that interface between ecology and management. I actively search for new methodologies from other disciplines that could be used to address practical problems in fisheries ecology. For example, many of my research investigations have required the development or application of principles from terrestrial ecology.

    Fatty acids and lipid classes in marine food webs, climate change in temperate and polar systems, essential fatty acid nutrition, trophic ecology, lipid biomarkers, larval nutrition, larviculture and lipid enrichment of live foods. 
    I study the mechanisms and consequences of environmental variation on energy uptake and compartmentalization in cold-water marine organisms. I am particularly interested in the effects of temperature, oxygen, oil contamination and pH on energy allocation, growth and development in early life stages of crabs and fish.  Further, I explore how these physical factors interact with climate-induced changes in food quality (total lipids and fatty acids) to influence animal survival.  I aim to provide environmentally-dependent physiological rates (i.e. growth rates, mortality rates, and tissue-specific lipid storage rates) that can be parameterized and modelled to make predictions about population persistence, biogeography and health of marine species.

    Volcanology, Igneous Petrology, Planetary Surface Processes (aeolian sedimentology/geomorphology)
    I am a field-based volcanologist. The questions I address start in the field – Nature is intriguing, and there are many things that make me go… “hmmm….now that is interesting” or “that doesn't fit what we know”, or simply “wow, that is really cool, lets find out more about this”. There are some core themes to my research. Projects my students and I are currently working on emphasize magmatism and volcanism in volcanic arcs, physical volcanology and petrology of explosive volcanic eruptions, effusion of crystal–rich lava, caldera (super)volcanism and the volcano-plutonic connection. To address these I use the volcanologists toolbox (Petrology, Geochemistry, Physical Volcanology, Geochronology, Remotely Sensed data, Geophysics) at all different scales. I am not an “expert” in any particular analytical technique, but I look for different tools and creative solutions for the problems of interest often collaboration with those who are experts. I like to think of this as "Volcano Forensics" - a CSI approach to volcanology. Our research projects have taken us to Chile, Peru, Argentina, Bolivia, Italy, Indonesia, China, and Japan. Read about our work at Lake Toba, a large caldera in Sumatra. I am also interested in Aeolian geomorphology. Why? While studying volcanic features in the high Andes, we couldn't ignore the fact that wind was producing an other-world landscape that was a valuable analog for the surface of Mars. Starting with yardangs, we have begun to address how the wind erodes and modifies high desert volcanic terrains. Our latest work is trying to understand how gravel dominated bedforms form and rates of aeolian erosion of ignimbrite. The broader impacts of our work relate to volcanic hazards, planetary surface processes, volcanism and climate, and Earth Science Education and Outreach (Visit our VolcanoWorld website). I am also committed to undergraduate research and Increasing Diversity in Earth Sciences.

    Atmosphere-ocean interaction, Stratiform clouds, Tropical meteorology
    I am interested in atmosphere-ocean interaction, and its influence on the climate. Much of my research focuses on the tropics. They receive the most sunlight, resulting in warm sea surface temperature, and strong fluxes of heat from the ocean to the atmosphere. Most of the heat transferred to the atmosphere is in the form of evaporation. Water vapor condenses in rain clouds and the heat of condensation drives the large-scale circulation of the atmosphere. Wind from the atmosphere blows across the ocean surface and drives ocean currents. Clouds themselves are an important player in atmosphere-ocean interaction, because they shade the ocean surface from the sun, keeping it cooler. I model or observe important and interesting regional processes, like strong ocean upwelling and stratiform clouds in the eastern tropical Pacific Ocean, and intraseasonal variability, organized deep convection, and its air-sea interaction in the central tropical Indian Ocean. I measure heat and momentum fluxes from ships by measuring radiation and turbulent temperature, humidity, and velocity fluctuations. I use data gained from observations and regional models to understand air-sea interaction and clouds, and to understand how well climate models simulate these processes.

    Tracer oceanography
    My research involves components of trace element and stable isotope geochemistry, biomineralization, and marine biology. I develop and use proxies, primarily trace elements in marine calcifiers, for reconstructing ocean circulation, temperature, and chemistry in the past. A few of the primary research questions I seek to answer: How do marine calcifiers make their shells? How do they exert control over trace element/Ca ratios and modify the trace element/Ca ratios so greatly from seawater. For example, understanding how foraminifera calcify and control their geochemistry has broad implications for the use of trace element/calcium ratios as paleo-proxies. Decades of research and empirically derived relationships show that many foraminiferal based paleo-proxies are fundamentally sound (the proxies work, we just don't know exactly why and/or how). I seek to find answers to these questions to improve paleo-proxies through culturing live specimens and applying laboratory based developments to specimens from fossil record.

    My overall scientific interest is to better understand the cycling of natural organic matter in the earth's surface, mainly in aquatic environments such as oceans, estuaries, rivers, groundwater, and lakes. A key objective of my research is to elucidate the role that organic matter plays on the global biogeochemical cycles of major elements (e.g., carbon, oxygen, nitrogen). Specific areas of my on-going research include:
    1. Understanding the processes controlling organic matter cycling in river-dominated ocean margins, including deltas and estuaries.
    2. Investigating the factors that control the generation and export of organic matter from the surface ocean and its transport, cycling and preservation in marine sediments.
    3. Reconstructing the sources and compositions of organic matter in sediments over glacial - interglacial scales.
    4. Assessing the role of natural organic matter on the behavior of particle reactive contaminants in coastal environments.
    5. Developing and applying novel analytical techniques including organic biomarkers and stable isotopes for the study of organic matter in the ocean.

    I am interested in using thermal processes to understand the Earth. All geologic processes involve the transfer of energy. Heat (energy) and temperature are fundamental to many earth processes, and quantifying the flow of energy and thermal budgets leads to an appreciation and understanding of Earth dynamics. These interests have led me along three paths.
    1. Marine Heat and Fluid Flow. See page on U.S. marine heat flow capability. I am trying to understand the curious observation that while midplate hotspot swells exhibit characteristics suggesting a thermal origin including, broad anomalous topography, underplated magmatic material, and young volcanism, at some hotspots, notably Hawaii, excess heat flow has not been observed. At the Hawaiian midplate swell heat flow values across the swell are resolvably lower than values off swell. We hypothesize that fluid flow within the archipelagic apron and upper oceanic crust might be responsible for the lower than expected heat flow values. I am currently seeking to understand the role of seamounts in channeling flow and advecting heat [Hutnak et al., 2008; Harris and McNutt, 2007; Harris and Chapman, 2004; Harris et al., 2004; Fisher et al., 2003]. See also The future of marine heat flow: defining scientific goals and experimental needs for the 21st century, Workshop Report, Fort Douglas, Salt Lake City, Sept. 6-7, 2007.
    2. Climate change inferred from borehole temperature-depth profiles. Changes in temperature at the surface propagate slowly downward into the Earth, perturbing the background temperature field. Due to the low thermal diffusivity of rock, temperature perturbations in the uppermost 300 m of the Earth record surface temperature conditions over the last 500 yrs. These subsurface temperature perturbations therefore can be used to reconstruct past ground surface temperature changes not only for this century, but also for the time immediately preceding installation of meteorologic stations, a period of time that is critical to climate change studies. Analyses of borehole temperature logs therefore both complement and extend the meteorological archive of climate data and can usefully be combined with proxy data [Harris and Chapman, 2005].
    3. Temperature and rheology. The thermal state of the lithosphere plays a large role in influencing geodynamics. Boreholes being drilled for strain meter emplacement as part of the NSF funded EarthScope Initiative provide excellent opportunities for new continental heat flow measurements. These measurements, combined with modern geodetic measurements, promise to improve our understanding of continental deformation [Harris et al., 2004; see also Thermal Processes in the Context of EarthScope Workshop Report].

    Sea ice dynamics
    Dr. Hutchings research interests revolve around sea ice dynamics and mechanics. She is active in field work to support validation and development of rheological models of sea ice deformation for climate investigations and ice drift and dispersion forecasting. Jenny participates in the development and use of sea ice rheology models in climate and regional studies. This includes collaboration with the Regional Arctic System Model team and a collaboration with researchers at University of Alaska Fairbanks to develop a discrete element sea ice model, Siku. Her interests include ocean-atmosphere interactions as modified by an evolving ice cover, and developing our understanding of how changing mechanical properties of the ice pack relate to positive and negative feedbacks in the arctic climate system. It is through these investigations we can understand the recent changes in sea ice volume. Supporting monitoring of this change Jenny leads Ice Watch, a program to standardise collection and archiving of visual observations of sea ice.

    • quantify irreversible fluxes of heat, salt, biology, chemicals and momentum
    • identify the processes (the pathways to turbulence) which produce these fluxes

    My research interest is the study of physical processes in coastal ocean. Big, small, long, short, high-frequency, low-frequency, stratified, unstratified, rotating, nonrotating, forced, unforced, surface, bottom, middle – I don’t care. If it’s physics and coastal, I’m interested. I am most interested in understanding the dynamics of the evolving structure of the density field over the shelf. How it is affected by external forcing and how it in turn affects the circulation within the coastal ocean. My approach is observational, using innovative sampling techniques – such as Autonomous Underwater Vehicles (AUVs) – coupled with modeling and analysis, to explain fundamental physical processes. In addition, I think that this kind of research needs to be approached with an interdisciplinary perspective, extending the understanding of physical processes to their impacts on biological, chemical and environmental processes.

    Heavy stable isotope geochemistry; geochemical tracer development; transport, transformations and environmental fate of metals/metalloids
    My research interests lie in natural biogeochemical cycling of metals and assessing the importance of anthropogenic activities as metal sources. Metal emissions to the environment from anthropogenic sources may be much larger than those from natural sources. These anthropogenic inputs disturb the natural biogeochemical cycling of many elements. My research aims to characterize the isotopic variation among metal sources and to quantify the extent to which reactions (physical, chemical and biological) cause isotopic fractionation of heavy stable isotopes, with the goal of developing these isotope systems as tools for source and process identification. Ultimately, my research seeks to aid environmental monitoring and remediation efforts and improve our understanding of natural and disturbing biogeochemical cycles.

    "The summit of Mount Everest is marine limestone. This one fact is a treatise in itself on the movements of the surface of the Earth. If by some fiat, I had to restrict all this writing to one sentence; this is the one I would choose." -- John McPhee, Annals of the Former World Conflict Ecology: I'm interested in better understanding how changes in land cover pattern or land use vulnerability may result from or potentially contribute to the process of conflict at regional or national levels. I use satellite imagery to measure long-term and spatially diffuse changes in forests, agriculture, and surface water, and consider potential relationships to conflict and sociopolitical power as well as land use policy and climate change. Most of my research involves spatial modeling and landscape pattern analysis, and I tend to use open-source machine learning, image processing, geospatial analysis, and spatial statistics programming tools.

    My research involves the physics of the nearshore coastal ocean including waves, currents, and sediment transport. I'm interested in using new observational and modeling tools to understand and make predictions of these processes --- often using a probabilistic approach owing to the dynamic/complex nature of the problem. Examples: - measuring statistics of fluid-sediment interaction at the seabed, using new instrumentation (e.g. acoustics) - instrumenting beaches to measure shoaling and breaking waves, and their interaction with seabed roughness - using beach cameras (Argus) with model-data assimilation to improve forecasts of nearshore currents (e.g. rip currents) I've also been involved in applying the same techniques in similar environments such as rivers and inlets. NOTE: Interested in joining my research group as a grad student, or gaining undergraduate research experience?  I'd love to hear from you!  Please contact me (wilsongr@coas.oregonstate.edu) with a brief description of your background and interests.

    I am interested in how marginalized people in vulnerable places migrate in order to adapt to climate change impacts. Migration is a geographical decision about how a person will apply his or her labor in pursuit of wages. The concern is that when poor people must rely on their wages to adapt to environmental distress, they risk slipping further into poverty. My research is motivated by three questions:
    1. As climate change renders some spaces uninhabitable, how will this change the spatial distribution of the human population?

    2. How are migration decisions constrained by climate change, local resource politics and political economies?

    3. How can we use the digital infrastructure (i.e. mobile phone networks, and internet usage patterns) to detect migration as a signal of shifting habitability?
    Pursuing these questions has led me to investigate displacement and migration around catastrophic flooding along the Atlantic coast of Honduras; glacier recession and shifting water resources in the Cordillera Blanca, Peru; and tropical cyclones in coastal Bangladesh.  I have found that migration takes place in the context of political economies in which national planning privileges certain uses for land, resources and labor. I have also found that migration takes place in politically charged contexts, where powerful actors control access to resources like land, housing and employment. This raises critical questions about the extent to which migration and wages can help people adapt to climate change impacts without slipping into poverty.  Data from the digital infrastructure for mapping invisible populations Migration is hard to measure, especially in the context of environmental degradation. For the past eight years, I have been experimenting with methods for measuring migration flows using data from the digital infrastructure. This led to my collaboration with Flowminder, Grameenphone and Telenor using mobile network data to measure displacement and migration flows around tropical storms in Bangladesh. See here for a summary of methods and aims. Illicit geographies: Narco-deforestation in Central America My research on the root causes of vulnerability and migration in Central America led me unintentionally to understand narco-trafficking as a major driver of deforestation and environmental degradation. The coastal lowlands of Central America's Caribbean register the highest rates of deforestation in the world, which in the space of a few short years has produced catastrophic flood regimes in coastal communities. What is the cause? Central America emerged in the mid-2000s as the "Gold Spike" in the inter-American drug trade. At its peak in 2013, >90% of all suspect air traffic originating in South America was destined for Eastern Honduras. Annually, billions of dollars in illicit capital flood into Central American economies, these dollars must be laundered. Much of this money is being invested in large-scale cattle ranching. This work published in Science and has been covered in over 300 news outlets, including New York Times, BBC, The Guardian, and National Geographic.

    Prospective Students

    I am interested in working alongside students to address sustainability questions using the conceptual tools of political ecology and land systems science. I would like to advise students who want to:
    • understand and predict patterns of migration, residence and labor as adaptation to climate change now and moving toward the end of the 21st Century.
    • develop experimental "near sensing" methodologies, for collecting spatial data using digital devices.
    • understand the grounded social and environmental realities of the Drug War in Central America.
    I strongly encourage students to apply who have been personally affected by Drug War policies, particularly, the uneven policing and prosecution of drug-related laws in our judicial system. A permanent record of drug-related legal violations will not work against your application: rather it indicates a personal stake in identifying and addressing the harmful outcomes of the Drug War.
