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:

  1. Spring and Summer 2021
  2. Summer 2021 only
  3. Summer and Fall 2021
  4. 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. 

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.

R/V Sikuliaq Cruise, Summer 2019

The Summer 2019 cruise aboard R/V Sikuliaq has begun. 2019 is the 50th consecutive year of samples taken at oceanographic station GAK1 (begun December 1970) and the 23nd consecutive year of Seward Line physical-chemical-phytoplankton-zooplankton-seabird sampling. However, many new things are happening too.

Special Studies

Deploying GEO mooring

One of our special studies involves several days of high-resolution sampling of the Copper River discharge plume. We suspect this plume is a source of iron (and other nutrients), therefore driving some of the high productivity in the Gulf of Alaska. To investigate this, we’ll be deploying drifters, making maps of data along the plume edge, and performing incubation growth experiment using both shelf and offshore water.

In addition, the Gulf of Alaska Ecosystem Observatory (GEO) is being deployed this week. During the next year, it will report oceanographic conditions in real-time. The GEO moorings will provide the NGA LTER program with year-long data about conditions in the Gulf, so we can know what is happening even when we can’t be there. Two of the three moorings in the array report real-time data on ocean surface conditions. You can view data from these moorings in the Ocean Data Explorer system provided by AOOS and Axiom Data Science:

Five Research Experience for Undergraduate students are also aboard. Most of their time is spent in the labs at UAF and WWU, but for a few weeks, they are experiencing life at sea. They are:

  • Adrianna, working with Russ Hopcroft (UAF),
  • Kate, working with Russ Hopcroft (UAF),
  • Ayanda, working with Seth Danielson (UAF),
  • Delphina, working with Suzanne Strom (WWU), and
  • Kelsie, working with Ana Aguilar-Islas (UAF).

Participants are also updating several blogs about their work.

Internet communication with ships in the Gulf of Alaska is spotty, but these blogs will be updated as often as possible. Katie Gavenus’s completed blog from the Spring cruise gives even more insight into our work.

2019 REU Potential Projects

Research Experience for Undergraduates

The ideas for REU projects give an overview of currently interesting research topics at the NGA LTER. They range from physics to chemistry to biology. They involve retrospective analysis of decades worth of data or cutting-edge sampling aboard R/V Sikuliaq. The following are project ideas submitted by UAF investigators. REU students might work one of them, or use them as inspiration to design their own summer project. At the end of the summer, students will present their findings.

REU project with Seth Danielson:

The physics of the Prince William Sound
Prince William Sound (PWS) is a fjord adjacent to the Gulf of Alaska. A shallow sill separates the deep waters within the fjord from the Gulf, which provides sheltered habitat for zooplankton that over-winter there during diapause. Since the Exxon Valdez oil spill, physical oceanographic measurements, such as temperature and salinity, have been taken in PWS. The REU student will assemble these measurements (and the density calculated from them) from multiple sources, and will compute monthly means and time-series of anomalies. Consequently, 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 properties vary from one year to the next?

The student will gain experience analyzing physical oceanographic data, and will code algorithms in either MATLAB or Python.

REU project with Ana Aguilar-Islas:

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 relative availability of macronutrients (i.e., nitrate, phosphate, silicic acid) and the micronutrient iron exert a key control on the phytoplankton community structure, which in turn influences higher trophic level communities.

The REU student will participate in the summer 2019 LTER cruise onboard R/V Sikuliaq in late June/early July. Onboard, they will:

  • Participate in water sampling while collecting macronutrients, and
  • Help perform iron dissolution experiments.

Back in the lab, the student will work with archived nutrient data to investigate inter-annual (2017 and 2018) and seasonal (spring and fall) variability in macronutrient distributions along the Seward Line in the NGA. The student will gain seagoing experience, will learn best-practices in the collection of seawater for nutrient analysis, will gain experience plotting and interpreting oceanographic chemical data.

REU project with Russ Hopcroft:

Computers help count zooplankton
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.

REU project with Russ Hopcroft:

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.

Contents of plankton net samples vary dramatically by station.
