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 17 to August 17, 2024. 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.

2000, B.S. Double Major in Zoology and Environmental Science, Rhodes University

Interests: In the Zooplankton Ecology Lab, we conduct research on how climate change and other anthropogenic disturbances alter zooplankton ecology at the individual, population, and community levels and thus the structure and function of marine ecosystems and services.

Potential Projects: We have two potential projects in my lab and are hoping to recruit two REUs this summer. Project 1: Active acoustic data can provide a look at the ocean’s preyscape, including a euphausiid krill, a key prey item for predators off the coast of Oregon including fish, whales, and seabirds. In this project, you will learn to process acoustic data using industry-standard software, conduct analyses to reveal the distribution of krill along the west coast of the United States, and study ecological relationships between krill and the environment. Project 2: Analyzing the caloric content of zooplankton can tell us about their value as food for higher trophic levels. In this project, you will learn the technique of bomb calorimetry and will investigate the caloric content of krill from the coast of New Zealand, with the goal of understanding the dietary value of krill to blue whales. Both projects will provide important experience in research in the field of biological oceanography.

Background and Skills Sought in Potential Undergraduate: We are looking for enthusiastic, hard-working students who are willing to put in the time it takes to acquire and hone specialized skills used in biological oceanography. You do not need to have prior experience only an eagerness to learn. Project 1 will require substantial computer-based work, while Project 2 will be lab-intensive.

Lorenzo Ciannelli

2002, Ph.D., Aquatic Fishery and Sciences, University of Washington
1993, Laureate, Biology, Universita' Degli Studi di Napoli "Federico II", Italy

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.

Potential projects: My primary research focus is on fisheries oceanography and marine ecology. 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.

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: 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).
