Funded by the National Science Foundation, the Research Experience for Undergraduates (REU) program offers students the unique opportunity to work on individual research projects, and participate in group field trips, seminars and science colloquia over a nine week period at CEOAS under the guidance of university scientists, who serve as mentors. The summer REU program runs from June 19 to August 18, 2023. Successful applicants receive paid round-trip travel to Oregon, on-campus housing for the duration of the internship, and a weekly stipend.

Research Areas

CEOAS offers a broad range of undergraduate research opportunities and engineering applications in the physics, chemistry, geology, and biology of the Earth, oceans, and atmosphere. CEOAS research areas include ocean ecology, biogeochemistry, geomicrobiology, fisheries oceanography, physical oceanography, autonomous ocean observing, atmospheric science, climate modeling, marine geology, sedimentology, paleoclimatology, and geophysics. We welcome applications from students with backgrounds and interests in any of these areas, including atmospheric science, biochemistry, chemistry, computer science, earth science, engineering, environmental science, mathematics, microbiology, or physics majors.

If you want to apply what you've learned in the classroom to real world problems, then a research experience in the earth, ocean, and atmospheric sciences at CEOAS may be right for you. The earth, ocean, and atmospheric sciences are applied sciences – we draw on knowledge from a variety of academic backgrounds to solve real-world problems. Examples include:

  • development and application of analytical chemistry techniques to parts-per-trillion measurements of individual species in complex solutions;
  • physics of heat and mass transfer in solid and fluid earth materials;
  • exploiting the physics of light to gather information about the oceans remotely;
  • development of computer code to help assimilate and model large observational data sets;
  • design and deployment of remotely operated autonomous sampling platforms in the ocean

A directory of potential mentors and undergraduate research areas appears below.

Interests: My primary research focus is on fisheries oceanography and marine ecosystem ecology. I am interested in studying the causes of temporal and spatial variations of marine populations. Most of my work revolves around early life stages of fish, as variability at the population level is closely linked to egg, larval and juvenile survival in marine organisms. Through these investigations I combine quantitative analyses (i.e., mathematical and statistical modeling) with more field and experimentally oriented approaches.

I study the causes of temporal and spatial variation of marine populations, and the conservation implications of the ensuing findings. Most of the work that we conduct is from data collected by federal management agencies (e.g., NOAA) in sub-arctic and temperate systems in both the North Pacific and the North Atlantic, and involves a fair amount of computational analysis. The goal of these analyses is to gain ecological understanding and provide scientifically sound advice in management and conservation issues. Methods that I use in my research include statistical analyses of long spatio-temporal data series, typically from surveys and other monitoring programs, combined bio-physical modeling for assessing distributions of fish with dispersal life history stages.

Background/skills sought in an undergraduate: Undergraduate students working in my lab have a strong desire to use quantitative and analytical methods in order to make ecological inference.

Jenny Hutchings

Ph.D., Remote Sensing, University College London
B.S., Physics, University College London

Potential Projects: We are looking for aspiring polar scientists with backgrounds in physics, mathematics, engineering or earth sciences to participate in a NASA funded project aiming to improve models of sea ice motion which may result in improved understanding of the drivers of recent Arctic sea ice changes. The Arctic Ocean sea ice cover has lost roughly half it’s mass over the last 30 years. This highly mobile and constantly evolving icescape insulates the Arctic Ocean from the atmosphere and radiates the suns energy back to space which, along with seasonal snowpack on adjacent continents and ice caps in Greenland and Antarctica, helps cool the planet. The loss of Arctic sea ice results in a positive feedback and participates in the amplification we see in surface temperature change within the Arctic over the last century. To start this feedback loop there needs to be a trigger, sea ice transport can precondition summer melt. You will investigate how this transport occurs in winter through analysis of sea ice cracking and subsequent deformation. Together with satellite remotely sensed imagery and drifting buoy data you can build a picture of the forces that result in sea ice motion. There is much to investigate, and a variety of projects we can offer ranging from structural analysis of sea ice making use of your geology background, satellite data analysis combined with ice drifting data to identify how sea ice drift responds to wind forcing and collation of these analyses to investigate if sea ice mass loss is impacting sea ice drift.

Clare Reimers

1982, Ph.D., Oceanography, Oregon State University
1978, M.S., Oceanography, Oregon State University
1976, B.S., Environmental Science, University of Virginia

Interests: Clare Reimers conducts research in biogeochemistry and chemical oceanography. Her lab group employs novel electrochemical methods to study how oxidation-reduction processes drive the carbon cycle in diverse marine environments. A major focus in recent years has been the use of aquatic eddy covariance methods to assess oxygen consumption rates by the seafloor across the Oregon shelf in all seasons. For another project, electrochemical devices placed across the sediment-water interface are being deployed to harvest low-levels of electricity to power sensors by using natural, continually renewed, chemical resources in sediment and at geochemical seeps as "fuel" and dissolved seawater oxygen as oxidant. This new technology functions like a microbial fuel cell, taking advantage of the voltage gradient that occurs in the top few centimeters of the sediment column.

Potential Projects: Interns working in Reimers lab would be engaged in both field and laboratory aspects of these and other interdisciplinary studies. They would be taught analytical techniques and given the opportunity to collect and interpret data sets that reveal spatial and temporal variation in biogeochemical processes. Students may also have the opportunity to go to sea on a research cruise on an oceanographic research vessel.

Mary Santelmann

1988, Ph.D., Ecology, University of Minnesota
1980, M.S., Biology, University of Michigan

Environmental and anthropogenic influences on species composition and species richness in agricultural, urban and wetland ecosystems, including effects of landscape composition and pattern on native biodiversity. 3. Ecology and biogeochemistry of wetlands and riparian systems.

Potential Projects: One of our projects this summer is continuing a study of the major ion composition and chemistry of coastal streams - we are exploring temporal and geographic patterns in several streams along the Oregon coast. The project would involve assisting in collection of water samples, and collection of field data (pH, Conductivity, temperature, salinity, dissolved solids)  associated with the samples. We expect that the REU student could develop a project of their own investigating and comparing variability in the data both within and between study sites, and over the course of the diurnal cycle.

Adam Schultz

1986, Ph.D., Geophysics, University of Washington
1995, M.A., Cambridge University (St. Edmund's College)
1979, B.S., Geology, Physics, Mathematics, Brown University

Interests: I study the formation and evolution of the Earth's crust and mantle from both a fundamental Earth Science perspective, and also for practical applications such as harnessing geothermal power, and for protecting critical infrastructure such as the power grid from risk due to interactions between the solar/geoospace environment and the solid Earth below. One area of particular interest is in applying geophysical methods based on electromagnetic principles to image the lithosphere and asthenosphere, to determine its physical and chemical state and to infer its geological history. We also target volcanic systems to study the relationship between deeper magma sources and shallower hydrothermal features. In addition to working on theoretical and computational problems, my lab is heavily involved in the practical aspects of designing and operating new instruments for terrestrial and seafloor observatory programs.

Potential Projects: I direct a long-running NSF and NASA funded continental scale magnetotelluric (MT) program to determine the 3-D electrical structure of North America’s crust and mantle and also lead a number of other field projects employing this electromagnetic imaging method to determine the structure, geologic properties and fluid content of the Earth's crust and mantle. An MT instrument measures the variations over time of the Earth's electric and magnetic fields, which provides information we use to construct 3-D images of the electrical conductivity structure beneath the surface of the investigation area. Each summer field season we also deploy a relocatable array of such stations across large regions of the US, as well as around specific targets of geodynamic interest.

As the arrays progress across the country, the data we produce is used to develop increasingly comprehensive images of the electrical conductivity structure of the North American crust and mantle. Conductivity is a very sensitive indicator of the presence of magmatic and aqueous fluids; it is sensitive to the temperature and compositional variations within different regions of the crust and mantle, and it is also an important tool for studying the distribution of volatile compounds within the Earth. We employ both professional and student crew members to install and operate our network of MT instruments. We are presently building a new generation of MT instruments and there may be opportunities for REU students to become involved in field deployments in the Pacific Northwest, as well as in laboratory calibrations and testing of new electric and magnetic field sensors.

Background/skills sought in an undergraduate: Background in physics, math, engineering or geology. Interest in field work or laboratory-based sensor development and testing.

Interests: 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.

Potential Projects: Oregon Shelf Glider Endurance Observation: Since 2006, we have maintained a small fleet of AUV gliders operating on the Oregon shelf sampling the temperature, salinity and velocity structure during the entire year.

Submesoscale Dynamics: Coordinated ship-based and and AUV glider-based surveys of fronts in the ocean. We are studying the finescale interleaving of warm, salty water and cooler, fresher water, focusing on frontal processes that occur in the presence of strong wind-forcing and extremely energetic internal waves (tides or inertial). We have data collected at locations all over the world: Gulf Stream, Taiwan, Vietnam, Gulf of Mexico ...

1991, B.S., Geology, California State University, Northridge

Interests: Igneous petrology, isotope geochemistry, electron probe microscopy

Potential Projects: Misti is a major andesitic stratovolcano located in the Central Volcanic Zone of southern Peru. Its cone is the result of effusive lava flows and dome building events punctuated by explosive activity. Over its lifetime, Misti has had a relatively high frequency of explosive eruptions that have produced wide-spread tephra-fall deposits. This project will focus on correlating volcanic deposits from one of its many explosive eruptions on one side of the volcano with a similar deposit in another location on the volcano. The candidate will evaluate the petrography of the tephra deposit including texture, crystal abundance and shapes and proportion of glass, and analyze the major and minor element compositions of those phases in a tephra-fall unit using Oregon State University’s electron microprobe analyzer. These analyses will serve to create in-depth documentation of mineral and glass compositions associated with a distinct tephra-fall deposit and allow the student to correlate the petrography and geochemistry of the materials to another characterized unit.

Background/skills sought in an undergraduate: The REU candidate will ideally have taken classes in mineralogy, petrology and petrography. It will be important for the candidate to be able to identify different volcanic phases (e.g., plagioclase, amphibole, biotite, pyroxenes) in hand sample and in thin section using a petrographic microscope. The candidate will receive guidance in the use of an electron microprobe for the analysis of various phases in a representative suite of volcanic samples from Misti volcano.

Interests: My research aims to better understand how the ocean "works" and how this impacts society now and in the future. I do this through a lens of integrating microbial processes with chemical cycles that are important to the earth system, often through exploring the deep-sea and polar regions to better understand the globe's biodiversity.

Potential Projects: Methane seeps are areas where the greenhouse gas methane is released from the seafloor and they are abundant along the US coasts. I am looking for someone to work with my team to better understand the chemistry of these habitats and how that can impact the microbes that can survive and thrive there.

Background/skills sought in an undergraduate: A student who is excited about better understanding the ocean and looking for experience in chemistry and microbiology.

Interests: Application of stable isotopes, trace element ratios, and radiogenic isotopes in marine sediments for palaeoenvironmental reconstructions and sediment depositional histories. Geochemical and paleomagnetic studies of marine sediments. Investigating deglacial changes in meltwater input, stratification, and biogeochemical cycling in high-latitude environments.

Potential Projects: At the last glacial maximum, the Salish Sea was occupied by the Puget Lobe of the Cordilleran Ice Sheet (CIS). Runoff from the southern margin of the ice was routed to the ocean through a now defunct river system. At some point during glacial retreat, the drainage connecting southern Puget Sound to the Pacific was abandoned. The student involved in this REU project will participate on a 7-day research cruise from June 7th-13th 2020. They will assist in collection of marine sediment cores, and will prepare samples for micropaleontological analyses. The student will learn to identify foraminiferal species, and will use those data to characterize environmental changes in the Pacific Ocean associated with the retreat of the adjacent Puget Lobe.

Background/skills sought in an undergraduate: Interest in sea-going field work on a research vessel, appreciation of mud, experience with or an interest in learning about sedimentology and micropaleontology, interest in Earth’s past climate.

Interests: Ocean Acidification Impacts on Shellfish, and Benthic Ecology and Biogeochemistry.

Potential Projects: Dissolution dynamics of oyster shell in Oregon estuaries. Oyster shell provides critical habitat for recruitment of new individuals to the population. However, little is known about the the lifetime of oyster shell in estuaries and the critical thresholds of population size, recruitment rates, and environmental conditions that ensure that the rate of new shell accretion exceeds loss. The project would entail measuring rates of shell dissolution and quantifying physical and geochemical characteristics of shell material.

Background/skills sought in an undergraduate: Interest in chemistry and method development

Interests: I run the Socio-Environmental Analysis (SEA) Lab in CEOAS. Our research uses tools from oceanography, ecology, economics, machine learning and applied math to characterize and understand the complexity and dynamics of socio-environmental systems. We take inspiration from complex adaptive systems generally: our interest extends to financial systems, the vertebrate immune system, housing markets, competitive socio-spatial systems (i.e. sports), and of course ecosystems. We are interested in learning from all these systems to improve our ability to live sustainably. We are interested in hyper-local scales, e.g. how people behave, as well as global scales, in particular how the earth system is changing.

Potential Projects: Predicting illegal fishing from oceanography, characterizing the spatial dominance of international fishing fleets, projecting changing distributions of fishing fleets with climate change, quantifying the emergence of novel marine ecosystems under climate change, designing financial risk management tools for protecting against climate shocks such as marine heat-waves, machine learning algorithms for identifying whales from high resolution satellite imagery, using an Earth System Model to model Mars.

Interests: Large-scale climate and atmospheric dynamics, climate variability and change, atmosphere-ocean-ice interactions, and climate impacts and responses in natural and managed systems.

Potential Projects: A) Novel analyses of North Pacific ocean-atmosphere variability. This project applies new techniques to assess the coupling between ocean and atmosphere over the North Pacific. Physical controls on the evolution of North Pacific variability are incompletely understood, but this variability impacts marine ecosystems as well as downstream climate and weather. B) Atmospheric response(s) to a changing Arctic. Arctic climate change is affecting global climate through the atmosphere. This project seeks to improve our understanding of the atmospheric response by isolating the atmospheric response from the myriad other coupled climate interactions.

Background/skills sought in an undergraduate: Required: intellectual curiosity in climate dynamics and a particular interest in the research areas and / or potential projects described above. Preferred: some background in atmosphere and / or ocean science and some experience with analytical computing (e.g., Matlab or Python).
