Interview: "Methane emissions from glaciated Arctic fjords could significantly contribute to atmospheric methane levels"

In this interview, Aleksandra Machowska explains her research on subglacial methane release, its role in the greenhouse gas budget, and her journey into polar science.

Can you describe yourself and the focus of your research at iC3?

My name is Aleksandra Machowska, I am a masters student here at UiT The Arctic University of Norway. I am writing my thesis within iC3 on subglacial methane release from glaciated Arctic fjords. My supervisors, Guillaume Lamarche-Gagnon and Gabrielle Kleber from iC3, are guiding me in this work.

Why is it important to study that?

Methane is a potent greenhouse gas, and my research aims to understand its release from the unique environments of Arctic fjords. This is crucial because it is underrepresented in the global greenhouse gas budget, which is central to understanding climate change.

Methane emissions from glaciated Arctic fjords could significantly contribute to atmospheric methane levels, yet this process remains poorly studied. By investigating these emissions, we can better understand the Arctic's role in the Earth's climate system and methane's potential impact on global warming.

You said Arctic fjords, where exactly? What is your regional focus?

My samples’ sites include three key locations with marine-terminating glaciers: the Independence Fjord in Greenland, from where I received samples from the GoNorth 2024 cruise; Fridjovhamna in Svalbard, which I visited in July for fieldwork; and Kongsfjorden, also in Svalbard. These fjords are ideal for this study due to their glaciated environments and unique sediment and water dynamics.

What are you doing with these samples?

After collecting the samples, I analyze them using gas chromatography in the geology lab at UiT. This technique allows me to measure methane concentrations in both water and sediments. The process involves running the samples through the instrument to detect and quantify methane levels.

In addition, I also have CTD data, which provides essential information about the physical properties of the water column. This data complements my methane measurements by helping to understand the environmental conditions.

Would you like to stay in research after your master's degree?

I am strongly considering staying in research. So far, I’ve been choosing an academic path that aligns with this goal, but it depends on personal circumstances and available opportunities.

What big question would you like to answer in the future?

I would like to explore the dynamics of methane throughout Earth's history, particularly during and after major glaciations. Understanding how methane contributed to the greenhouse gas budget in the past can provide insights into its role in current and future climate scenarios.

What are some of the biggest challenges you face in your master's degree, and how do you overcome them?

The biggest challenge for me is building self-confidence and accepting that not everything goes as planned. Moving abroad and studying in an international environment has been transformative, helping me grow both personally and professionally.

What’s one thing you’re looking forward to in the next year, personally or professionally?

Professionally, I am looking forward to analyzing my research results and gaining insights into methane release from Arctic fjords. I am also excited to be part of a research group, where I can share experiences, discuss findings, and learn from others. This collaborative environment is something I’ve always wanted to be part of, and I believe it will be a valuable experience for my growth as a researcher.

Why did you decide to move to Norway and study here?

I wanted to study Arctic research and explore the northernmost regions, including Svalbard. The UiT offered the perfect opportunity to pursue these interests. I had visited Norway before and found it beautiful, and I was drawn to the research possibilities in the Arctic.

What does an ideal day off look like for you?

An ideal day off involves skiing in winter or hiking/kayaking/camping in summer, followed by a nice dinner with friends. I’ve embraced the Norwegian lifestyle and enjoy outdoor activities.

Do you have a motto or a last word to share?

For anyone hesitant about moving abroad, I encourage them to take the leap. It’s a challenging but rewarding experience that offers immense personal and professional growth.
