INSTAAR is now accepting applications for the 2025 Summer Scholars cohort

Each year, the scholarship provides funding for two CU �鶹ӰԺ graduate students to continue their research over the summer. Priority is given to INSTAAR graduate students who enhance diversity, equity, and inclusion within the institute. Recipients receive a research stipend equivalent to a 50% RA position for three summer months.

Apply, donate, or learn more
Deadline March 5th, 2025

In 2024, the award went to two ambitious PhD students hard at work on research projects on opposite ends of the world. This week, INSTAAR sat down with Natalie Aranda and Jed Lenetsky to learn more about their experience as summer scholars.

Jed Lenetsky (ATOC)

What did the scholarship enable you to work on last summer?

I was able to advance my research on two different projects in Baffin Bay.

The first project looks at how future climate scenarios might affect sea ice, marine life and other oceanographic conditions. That one is focused on the North Water Polynya, which is one of the Arctic's most productive ecosystems. Previous funding from the NSF ran out before the summer, so the scholarship was critical. It allowed me to complete revisions on a manuscript, and the resulting article is now under review for publication in the American Meteorological Society’s Journal of Climate.

The second research project examines oceanic changes in the Davis Strait in southern Baffin Bay. The Summer Scholars funding allowed me to spend time processing and analyzing data. I also used some of the funds to participate in a research cruise through the Davis Strait this fall (and gather more data).

What challenges arose in your work, and how did you respond?

It’s really difficult to process and gain meaningful insights from imperfect observational data — which is what I’m attempting to do with the Davis Strait project. I’m still working it out, but I am learning a lot through the process. I’m confident it will make me a stronger scientist once I get to the other side.

What was your proudest moment?

Definitely submitting my revised paper on the North Water Polynya for publication. We substantially improved the study by working on an assessment of relevant model processes over the summer. The assessment showed that the physical processes driving the formation of the North Water Polynya in the model were similar to the real world. The findings added rigor and boosted our confidence in the research.

Natalie Aranda (CEAE)

What did the scholarship enable you to work on?

The funding gave me time to work through an important and difficult step in my dissertation research.

I was able to devote my time and focus toward processing biological samples that I collected in Antarctica back in early 2023. The samples didn't arrive back in the U.S. until around March of that year and, up until last summer, I ran into a bunch of road blocks processing them into usable data. This scholarship allowed me to dedicate myself full time to the task, and I ended up completing the work before the start of the semester.

This fall, I was finally able to move on and begin interpreting my data. Basically, I’m looking at chloroplasts in diatoms under a microscope and counting how many of them were alive when they were collected. I’m looking for a trend that tells us where in the stream there is more likely to be live or dead cells.

What challenges arose in your work, and how did you respond?

Ha! Staring at a microscope for the entire day makes your eyes blur and your head spin, especially when you’re not finding what you are looking for. The scholarship gave me the space to come back the next day (and the next day) to try again.

What was your proudest moment?

Certainly, it was when I finished processing my last sample. It was a long time coming, and it felt great. I actually finished at the end of July, which gave me enough time to put together a poster for the Scientific Committee for Antarctic Science conference, which was held in Pucón, Chile at the end of August. I got some feedback at the conference that has been critical in my approach to data analysis this year.

INSTAAR at AGU 2024 David J Lubinski Thu, 12/05/2024 - 12:01

Gabe Allen , David Lubinski

Each year, more than 25,000 earth and space scientists from around the world convene for the annual convention of the American Geophysical Union. This year’s conference runs for a week on 9-13 December in Washington, D.C., and will feature talks and posters from INSTAAR’s faculty fellows, faculty research associates, postdocs and students. Our Institute’s contributions will span the globe, touching on Earth systems in the oceans, alpine and polar regions.

Research highlights, from Monday to Friday

A sea-ice free arctic

“The first ice-free day in the Arctic Ocean could occur before 2030” — it’s a stark title for faculty fellow Alexandra Jahn’s latest paper, which was published in Nature on December 3rd. Jahn will give an invited talk about her research during a Monday session. In it, she will detail her work to model the climatic conditions that could lead to an ice-free arctic in the near future. Her collaborator on this project was the Swedish earth scientist Céline Heuzé. Read more about this project in CU �鶹ӰԺ Today. [ Monday a.m. talk ]

Woody encroachment into alpine tundra

Although woody encroachment has been well-studied in the arctic, less is known about its effects in alpine tundra. Katya Jay (INSTAAR affiliate and alum, now at NEON and CU �鶹ӰԺ ESIL) and her co-authors have combined multiple imagery datasets with many other measurement types to try to understand how encroachment happens over time. The team included Katharine Suding, Will Wieder, and two CU �鶹ӰԺ colleagues. Jay will present their findings in a poster session on Tuesday. For more about her recent research, watch her talk at CU �鶹ӰԺ's Earth Lab this spring. [ Tuesday a.m. poster ]

Alpine lake biomarkers in Wyoming

Lipid biomarkers preserved in lake sediment provide valuable information about past climate and environmental changes. One such class of biomarkers, brGDGTs, has proven its value as a paleothermometer and has promise for reconstructing other key environmental variables as well. INSTAAR research scientist Jonathan Raberg (also with University of Wyoming) will present his collaborative work to compare sediment brGDGTs with other environmental proxies in Wyoming alpine lakes. [ Tuesday a.m. talk ]

Warming and sediment on the Canning River

Faculty fellow Irina Overeem - with a team of mostly INSTAAR researchers, alums, and affiliates - spent the past two field seasons documenting changes on the Canning River in Alaska. She will speak about their research on Tuesday. The project investigates the transport of sediment and nutrients from the Alaskan permafrost out to the Arctic Ocean. Overeem and PhD student Josie Arcuri are also the stars of a new film about the project titled “Icy River” by �鶹ӰԺ-based documentarian Ryan Vachon. INSTAAR will host a screening and a Q&A on January 30th. [ Tuesday a.m. talk ]

Carbon cycling in cold regions

Arctic rivers move, process and store an immense amount of organic carbon — carbon that has built up in the surrounding permafrost over millennia. Faculty fellow Suzanne Anderson will present a poster on Tuesday detailing her work to elucidate the carbon cycles, sources and sinks of these icy waterways. Her research sheds light on these poorly-understood systems during a time when climate change is impacting them on every level. Her collaborators include Irina Overeem, Robert Anderson, Marisa Repasch and Josie Arcuri. [ Tuesday p.m. poster ]

Snowmelt and subalpine forests

As the climate warms, subalpine forests experience longer growing seasons and more variable winter snow. In an invited talk on Thursday, faculty fellow Noah Molotch will detail his investigation into these important ecosystems over the past quarter-century. His work draws on decades of remote sensing data that shows the importance of snowmelt on ecosystem productivity. His collaborators include Eric Kennedy, John Knowles, Sean Burns and Peter Blanken. [ Thursday a.m. talk ]

Marine heatwaves and ocean acidity extremes

PhD student Samuel Mogen, Nikki Lovenduski and collaborators take aim at predicting marine heatwaves and ocean acidity extremes in a new paper in Nature Geoscience. Their new model is adept at forecasting these acute events from months to a year in advance, with varying degrees of certainty based on the event type and location. Mogen will present the team's poster on Thursday in a session on climate variability and predictability. Read more about the forecasts in a recent INSTAAR news story. [ Thursday p.m. poster ]

Flooding in the 21st Century

Faculty fellow Albert Kettner will give an invited tallk on Thursday during AGU’s “Changing Climate: Associated Natural Hazards and Impacts” session. He will focus on his recent work to simulate flooding on a global scale at the end of the 21st century. His research documents changes in the magnitude and frequency of flooding under a specific climate scenario, in which emissions are reduced slowly. His collaborators include Sagy Cohen, Irina Overeem, Balazs Fekete, Robert Brakenridge and Jaia Syvitski. Read more about Kettner’s work in a recent INSTAAR news story. [ Thursday p.m. talk ]

Microbes and methane growth 2020-2022

A new analysis from Sylvia Michel, Pieter Tans, Reid Clark, Jianghanyang (Ben) Li, and collaborators investigates the root cause of a recent atmospheric methane spike. Their finding suggests microbes have been emitting more methane than fossil fuels in recent years. Nonetheless, reducing fossil fuel consumption remains key to addressing climate change. Their work was recently published in Proceedings of the National Academy of Sciences. Michel will give an invited talk on Friday in a session on Isotopes of the Atmospheric Components. Read more about this study in CU �鶹ӰԺ Today [ Friday a.m. talk ]

Mountain hydrology and biogeochemistry

Presentations on 'Mountain hydrology and biogeochemistry in a changing world' are being held in honor of Mark “SnoBear” Williams (INSTAAR Fellow Emeritus and Geography Professor Emeritus), who passed away in 2023. Presenters are invited to build on Mark's diverse contributions and address the question: What’s next for mountain hydrology? A total of 25 presentations will be made. Noah Molotch is the primary convener, assisted by Diane McKnight and Jennifer Morse, plus INSTAAR alums Paul Brooks (University of Utah) and Alia Khan (Western Washington University).

While fire is a normal part of the ecosystem of the Mountain West, fires that push into urban areas are destructive to those landscapes. The effects of urban fires, known as urban conflagrations, can have long-term effects on our waterways' local ecology. KUNC host Stephanie Daniel speaks with Lauren Magliozzi. They discuss what we should be looking for in the water after a major wildfire.
