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. Experience participating in field research and/or working in laboratory is desirable. Members of groups under-represented in earth and environmental science are particularly encouraged to apply.
Positions include full stipend, health insurance, and a tuition waiver. Initial acceptance is typically at the Master’s level with possibilities to later expand into a Ph.D., or directly into a Ph.D. for those already at the M.S. level.
UAF’s College of Fisheries and Ocean Sciences provides application information. For Fall 2019 admission, UAF must receive applications for graduate admission with all supporting documentation, transcripts and test scores no later than June 1, 2019. Contact the appropriate faculty advisor (see below) before April 15, 2019 for more specific information.
Research Experience for Undergraduates (REU) Summer 2019

Sikuliaq expands ways to study Gulf of Alaska ecosystems
Studies of zooplankton such as copepods have expanded because of LTER funding and the workspace available aboard R/V Sikuliaq. For instance, CFOS researcher Russ Hopcroft isolates, identifies, photographs, and assesses live animals soon after net tows. Read full story >>
Submarine ‘airplane’ revolutionizes measurement of seawater content
CFOS’s Seth Danielson operates an Acrobat instrument, which he described as the underwater version of an airplane. The Acrobat measures temperature and salinity on fine spatial scales. As a result, LTER scientists can track freshwater from the land and investigate how it mixes with ocean water. Read full story >>
Sikuliaq improves analysis of phytoplankton’s nutrient needs
CFOS’s Ana Aguilar-Islas brings her own specialized clean sampling instruments onto Sikuliaq so she can quantify nutrients like iron that are essential to phytoplankton. Additionally, Aguilar-Islas and WWU’s Suzanne Strom performed incubation experiments to study how iron availability affects plankton growth. Read full story >>
Nutritional flexibility in ciliates and dinoflagellates stabilizes food chains in the Gulf of Alaska. WWU’s Suzanne Strom isolates cells and preserves them soon after they are collected, so she can analyse them at sea and in her onshore lab. Read full story >>
In a few short days, 23 scientists and educators will embark on our first LTER cruise aboard the R/V Sikuliaq, April 18 – May 5, 2018. Cruises are integral to our research and we anticipate having three each year – in May, July, and September. This cruise continues decades of time-series of measurements of the spring phytoplankton bloom along the Seward Line. As such, its many objectives center on the physical and biological processes that generate and sustain the spring bloom.
This cruise continues the sampling begun in fall 1997 under the NSF/NOAA NE Pacific GLOBEC program, and supported subsequently a consortium of the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council’s (EVOSTC) Gulf Watch. This is the first cruise as part of the NSF’s Northern Gulf of Alaska Long-term Ecological Program (NGA-LTER). The core scientific purpose of the Seward Line project is to develop an understanding of the response and resiliency of this marine ecosystem to climate variability. This cruise marks the 21st consecutive spring cruise for the Seward Line in the NGA, including Prince William Sound (PWS), and the 48th year of observations at GAK1.
Determine thermohaline, velocity, light, and oxygen structure of the NGA shelf.
Determine macro- and micro-nutrient structure of the NGA shelf.
Share the experience through outreach/media activities.
To achieve the objectives, the cruise will visit four cross-shelf transect lines plus stations within Prince William Sound. At each station, operations will be divided into day and night tasks. In the day, we will perform CTD measurements, bottle sampling, and perform intensive sampling and productivity experiments at selected locations. At night, net tows for zooplankton will catch the critters when they rise in the water column to feed. The shortness of high latitude nights in May will mean more daylight work than nighttime work.
The LTER program networks (now) 28 individual research sites. LTER’s unique ecological investigations measure changes over years and decades in various environments. Each LTER site involves dozens of researchers and depends on partnerships with hosting entities like universities, national forests, or non-profit organizations. There are other LTER sites in Alaska: Bonanza Creek and Toolik Lake, and another new marine site in the Beaufort Lagoons.
The Seward Line is a long-term observational program on the Gulf of Alaska shelf. It was originally undertaken by the Northeast Pacific GLOBEC program from 1998–2004. During the years 2005–2009, sampling along the Seward Line continued with funding from the North Pacific Research Board. Most recently, funding has come from a consortium of NPRB, AOOS, and EVOS (see our Site History.)
The purpose of our research has been to develop an understanding of the response of this marine ecosystem to climate variability. Hence, the Seward Line cruises determine the physical and chemical oceanographic structure, the primary production, and the distribution and abundance of zooplankton. We then examine the seasonal and inter-annual variations in these measurements.
LTER -A New Partner
Having a new partner in the funding consortium will enable expansion of our program’s elements. For instance, a third annual cruise will be performed between the two cruises in May and September. In addition, we’ll be able to perform more in-depth experiments on the processes that enable the high productivity in the Northern Gulf of Alaska area. And finally, the LTER Network’s emphasis on education, outreach, and data availability will also encourage growth in these areas.
Right now, we are planning our next cruise which will be aboard the R/V Sikuliaq in mid-April 2018. There are a lot of elements that must be balanced when planning a cruise. Of course, time, money (including that for processing samples later on shore), and the program objectives all influence the cruise plan, but there are many other facets to consider.
For one thing, there are logistical elements that limit where the cruise must start and in what order the stations will happen. These include:
Towing for zooplankton must be done during the day, when they are high enough in the water column to catch
Productivity experiments must be done during the day when there is sunlight
Time spent traveling between sampling locations (deadheading) must be minimized
Equipment and personnel must be delivered to and retrieved from the ship
In addition, we must incorporate elements of previous studies to insure continuity between measurements:
