The Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) project invites Alaska Native undergraduate students to participate in our interdisciplinary project during 2021.
Timing options for student involvement:
Spring and Summer 2021
Summer 2021 only
Summer and Fall 2021
Spring and Fall 2021
Any of the first three options include an opportunity to participate in a research expedition (dates to be determined as sea activities may be subject to quarantines, personnel reductions, and other restrictions due to COVID-19).
NGA LTER is one site within the national LTER network. Our research team investigates the features, mechanisms, and processes that drive NGA ecosystem production and foster its resilience. Scientists conduct ship-based observations and experiments, do research in land-based laboratories, run computer models of the ocean, and communicate findings to students and the public through education and outreach partners.
We seek a Alaska Native undergraduate student with interest in the Northern Gulf of Alaska to work with our University of Alaska Fairbanks team. Student research will integrate with work currently being done on the NGA LTER ecosystem. The time period of this REU position could includes our summer expedition aboard R/V Sikuliaq, so participation in ship-board research activities is possible, as is work that fosters partnerships with other disciplines. Research themes include biogeochemical cycling, microplankton ecology, physical oceanography, chemical oceanography, zooplankton ecology and molecular studies. For more information on potential research projects, please see the potential projects and mentors listing or contact any mentors directly to discuss other possible projects.
This REU opportunity is not limited strictly to oceanographic research, but can be a project that promotes partnership between marine science and other disciplines. Projects can be related to fields including but not limited to visual arts, music, education, engineering, communication. Participation could include joining a research expedition to the Northern Gulf of Alaska onboard R/V Sikuliaq, or it could be carried out fully at the UAF campus. The student will present their work to the UAF LTER community when the project is completed.
Stipend of $5760 for a position that requires 480 total working hours.
Additional funds may be available to offset housing and transportation costs.

Ideas for REU projects give an overview of current research topics at the NGA LTER, and include aspects of biological, chemical and physical oceanography in the northern Gulf of Alaska. Projects involve retrospective analysis of decades worth of data, or cutting-edge sampling aboard R/V Sikuliaq. The following are project ideas submitted by NGA LTER investigators. REU students might work on one of them, or use them as inspiration to design their own research project. At the end of the summer, students will present their findings.
The marine algae that form the base of the marine food web require essential nutrients to grow. For some micronutrients (e.g. iron and manganese) the seafloor is thought to be a potentially important source, but quantifying this seafloor source is difficult. Naturally-occurring radium isotopes have a distinct seafloor source, and once they enter the water column they decay at well-defined rates. Therefore, by detecting radium alongside micronutrients in surface waters, we may be able to calculate the rate at which seafloor-derived nutrients are transported into surface waters, and if we do that, we’ll add an important piece to the complex puzzle that is the Northern Gulf of Alaska biogeochemical cycle.
During the 2021 summer LTER cruise on R/V Sikuliaq, the REU will involve collecting water samples, extracting radium isotopes from samples onto fibers, and measure radioactivity of the fibers using our onboard alpha counter. After the cruise, the student will combine their radioisotope data with physical and biological information to understand the role of the seafloor in altering the physics, chemistry, and biology of the overlying waters.
While the amount of radioactivity we measure is completely harmless, we hope the ‘fallout’ of our results make a real impact!
My work broadly encompasses the phytoplankton, micrograzers, and organic carbon cycle in Gulf of Alaska waters. Projects at sea could include experiments to test the salinity tolerance of different micrograzers, or field sampling to look at the occurrence of mixotrophy (photosynthesis and grazing by the same single-celled organisms). If we are unable to go to sea, data analysis projects are possible, including comparison of remote sensing (satellite) and field measurements of phytoplankton biomass and production.
Prince William Sound is a fjord-rimmed estuary adjacent to the Gulf of Alaska. A shallow sill separates the deep waters within the fjord from the greater Gulf; the deep waters provide sheltered habitat for over-wintering zooplankton. Since before the Exxon Valdez oil spill, physical oceanographic measurements such as temperature and salinity have been taken in Prince William Sound. The REU student will assemble these data from multiple sources, and will compute monthly means and time-series of anomalies. With the data we can investigate: Do the deep waters in PWS get replaced every year? Are there trends in the temperature and salinity properties? How much do the deep subsurface properties vary from one year to the next? The student will gain experience analyzing physical oceanographic data, and will code algorithms in the MATLAB computational environment.
Investigating nutrient cycling in the Northern Gulf of Alaska (NGA)
Along with light, nutrients are essential resources for phytoplankton (unicellular primary producers). In the NGA, the availability of macronutrients (i.e., nitrate, phosphate, silicic acid) and micronutrients (e.g., iron, manganese, copper) influence the phytoplankton community structure, which in turn influences higher trophic level communities. Projects at sea could include dissolution experiments from various marine particles, or collection of aerosol samples to investigate the solubility of aerosol-derived micronutrients. If we are unable to go to sea, projects could include analysis of previously collected samples to determine manganese and aluminum content.
NGA-LTER scientists collect millions of zooplankton during our net tows in the Gulf of Alaska. These must be identified into species and counted to order to understand the Gulf’s community structure. But that is tedious work. Therefore, we are teaching computers to do it for us. First, a watertight, flat-bed scanner (ZooScan) creates a digital image of a plankton sample from a net tow. Then software isolates individual images and sorts them into taxonomic groups (or particles and detritus). To teach the software how to do the sorting, scientists create a training set and then double-check the output. The REU student will gain lab experience as they scan and sort samples, and then will have the opportunity to look for differences in communities across stations and cruises.
2. Telling sisters apart
The Gulf of Alaska zooplankton contains many examples of closely related “sibling species”. These species occupy similar niches in the environment, but are slightly different in ways that may create advantages under changing conditions. It is likely that climate change acts by tipping the scales on which sister species are more successful. Unfortunately, zooplankton sampling in previous years did not always differentiate between these sisters. To gain knowledge about how things have changed in the NGA over the years, we hope a detail-oriented REU student will look back through our archived samples. They will help establish the shifting ratio of two keystone copepod species during the first decade of our time series, while they gain experience in microscope work and taxonomic classification. Moreover, we are also open to other small projects that might utilize our historical samples.
Zooplankton species that inhabit the world’s oceans are often very difficult to tell apart just by looking at their morphological features under a microscope. In the Gulf of Alaska there are species that look like identical twins, yet their genetic makeup is different, a term referred to as cryptic speciation. DNA barcoding is a tool that allows researchers to identify organisms to the species level and to tell these “twins” apart by analyzing the differences in the cytochrome oxidase I (COI) gene. This project would allow an REU student to focus on DNA barcoding one or more species from various groups of zooplankton of their choice. This student would get to work in both the zooplankton and genetics labs at UAF. They will work with specimens from samples previously collected from the Gulf of Alaska and get the opportunity to collect and pick their organism(s) of choice at sea during the summer LTER cruise. The student will gain experience with extracting DNA from zooplankton and running PCR (polymerase chain reaction) to target and amplify the COI gene. They will also learn how to analyze DNA sequence data and to determine if a species exhibits cryptic speciation. Any sequences generated by the student will be incorporated into a publicly available zooplankton DNA sequence database that is used by researchers worldwide for molecular-based zooplankton studies. No prior knowledge of genetics by the student is needed for their project to be successful.
Although the NGA LTER has a successful record of fieldwork during the COVID-19 pandemic, future research activities may be subject to quarantines, personnel reductions, and other restrictions. We anticipate that conditions allow for broad, in-person REU involvement in 2021. If not, we will pursue other avenues to maintain our 2021 REU program, including remote options.
The Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) project invites undergraduate students to participate in our interdisciplinary oceanographic research this summer.

The Oceanography Department in UAF’s College of Fisheries and Ocean Sciences is seeking a post doctoral scholar to work with Gulf Watch Alaska. The postdoc will contribute to existing data synthesis efforts and lead new analyses.
Gulf Watch Alaska
Gulf Watch Alaska (GWA) is the long-term ecosystem monitoring program of the Exxon Valdez Oil Spill Trustee Council. GWA partners with the Northern Gulf of Alaska Long-Term Ecological Research (NGA LTER) project to monitor the northern Gulf of Alaska ecosystem. In fact, NGA LTER is an example of an GWA project that has existed for multiple decades with resulting long-term physical and biological time series for the Gulf of Alaska.
GWA investigates three main ecosystem components:
Environmental Drivers (physical and biological oceanography),
Nearshore Ecosystems (intertidal and coastal food web), and
Pelagic Ecosystems (forage fish and predators of the pelagic food web).
GWA Science Synthesis
GWA supports annual field sampling efforts. However, it is also conducting cross-component science syntheses that focus on the effects of the recent northeast Pacific marine heatwave.
The postdoctoral scholar for this project will contribute as lead author and as co-author to GWA program synthesis products. They will collaborate with their UAF faculty advisor, GWA investigators, and the GWA Science Coordinator and ecosystem component leads. Together, they will design and conduct studies related to the phenology, magnitude, spatial variability, and recovery time of biological responses to and physical drivers of the marine heatwave. Additionally, other biophysical mechanisms of population regulation in the Gulf of Alaska may also be addressed.
Ecosystem Indicators and Management
These synthesis activities will support management actions by informing the ecosystem-based fisheries management of the North Pacific Fishery Management Council. For instance, the postdoctoral scholar will work with the GWA Science Coordinator to update existing and develop new ecosystem indicators to be used in NOAA’s Gulf of Alaska Ecosystem Status reports and Ecosystem and Socioeconomic Profiles.
In addition, the post-doctoral scholar will also provide technical review and editing of manuscripts, reports, and work plans for the GWA Program Management Team. They will also present results of their research at GWA meetings, scientific conferences, and to the public.
To learn more about this position and to apply, please visit Careers at UA. The deadline is November 30, 2020.
We are seeking new partners for the newly installed Northern Gulf of Alaska shelf moored ecosystem observatory (GEO).
The M.J. Murdock Charitable Trust funded the University of Alaska Fairbanks (UAF) to construct a moored Gulf of Alaska Ecosystem Observatory (GEO) in late 2017. Consequently, in 2018-2019, investigators designed the system, purchased components, assembled the moorings, and finally deployed the moorings in July 2019.
Now, an array of one sub-surface and two surface moorings collects high-resolution biological, physical, and chemical data year-round. Some sensors report data in real-time.
This year, the Murdock Trust is making $42,600 in “seed” funds available to bring new partners into the observatory consortium. As a result, we seek short proposals by UAF-based researchers for innovative new observing technologies that can be integrated into the upcoming May 2020 GEO deployment. In other words, this effort aims to encourage new partnerships and technology developments that can be applied to ocean observing via moorings in Alaska’s marine environment.
Interested investigators should e-mail a project description (2-page limit, exclusive of references and budget) and itemized budget to email@example.com prior to Friday, October 4th, 2019. After notification of proposal success (by November 1st), funds will be available immediately and need to be spent before the end of FY20. In all, we anticipate funding 1-3 proposals. However, by stipulation of the Trust, all seed funds must go to UAF-based researchers.
Graduate Student Opportunities at UAF, Starting Fall 2019
The Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) project announces multiple openings for graduate students at the University of Alaska Fairbanks that will begin Fall, 2019. Specialities include trace metal biogeochemistry, zooplankton ecology or physiology, and high latitude physical oceanography.
This project is part of the NGA LTER site. Therefore, student research will focus on the enhanced production and high environmental variability characteristic of the ocean shelf and slope regions of the NGA. This is a field intensive project with 3 yearly cruises from spring to fall. Projects will include fieldwork on UAF-operated R/V Sikuliaq and smaller regional vessels.
The student will be required to present work at international conferences, and to produce publishable manuscripts. Additionally, they join the national LTER network, with the opportunity of interactions with graduate students at other sites as a member of the LTER Graduate Student Committee. Collaboration with the interdisciplinary LTER research community is essential.
Applicants must have a strong background in oceanography and/or marine biology, chemistry, or physics, as well as strong written and oral communication skills.

In 2018, educators participated in each of our three Gulf of Alaska research cruises. Michele Hoffman Trotter, Per Fosstveit, and Mark Van Arsdale filmed creatures, helped with sampling, and developed lesson plans that will introduce students to our Alaskan ecosystem. Altogether, their contributions enabled our LTER program succeed. In general, however, it’s been challenging to connect with teachers and educators who want to get involved in our future cruises.
Over the summer, our marine education specialist, Marilyn Sigman, researched existing teacher research experience programs to find the best partner for the NGA LTER. Luckily for us, Mr. Van Arsdale joined us via NOAA’s Teacher at Sea program (TAS), which watered the seed of this new opportunity. As a result, NOAA and CFOS-UAF have made an agreement that will allow more K-12 teachers and marine educators who work in informal settings to take part in our research. In 2019, TAS’s established procedure will recruit teachers to come on our cruises. The educators will also take advantage of TAS infrastructure to post blogs and will participate in the network of TAS alumni. More information about NOAA’s program can be found at the TAS FAQ.
For the 2019 field season, educators will apply through NOAA’s TAS Online Application. We are spreading the word to teachers, informal educators, and administrators, particularly emphasizing educators in Southcentral Alaska.
Interested teachers should apply online before November 30, 2018, for the 2019 Teacher at Sea field season (sample application). Both K-12 teachers and informal educators (such as museum docents) are eligible to apply.
