Nikolas Olson Aksamit is an Associate Professor in the Department of Mathematics and Statistics at UiT The Arctic University of Norway, where he conducts interdisciplinary research at the intersection of applied mathematics and environmental science. His work focuses on understanding coherent structures in fluid flows relevant to the coupling between the cryosphere, atmosphere, and hydrosphere. His research interests include applied mathematics, nonlinear dynamical systems, fluid dynamics, Lagrangian coherent structures, snow science, and climate dynamics. He develops mathematical tools to analyze complex environmental systems, particularly in polar and alpine regions, with applications to sea ice, blowing snow, and ocean turbulence. His work bridges theoretical modeling with field observations and data analysis. The recent articles reflect a strong trend in using Lagrangian methods and nonlinear dynamics to study geophysical flows. Key themes include the detection of coherent structures in turbulent flows, sea ice dynamics, climate modeling, and the application of machine learning to oceanographic data. His publications span high-impact journals in fluid mechanics, geophysics, and environmental science, often in collaboration with leading experts in dynamical systems and climate science. He is a member of the research group Changing Arctic and contributes to the project Development of nonlinear dynamics-based techniques for sea ice diagnosis . While no formal students or awards are listed, his active publication record indicates a vibrant research program. His work has implications for climate prediction, polar monitoring, and environmental engineering.
Alun Hubbard serves as Professor of Glaciology and Arctic Five Chair at UiT The Arctic University of Norway's Department of Geosciences in Tromsø. His research focuses on ice sheet dynamics, climate interactions, and Arctic environmental systems through field-based geophysical investigations. His primary research domains include Glaciology , Climate Science , and Arctic Geophysics , with specialized expertise in ice-ocean-atmosphere interactions, glacial erosion processes, and hydrological systems of polar ice sheets. Current work emphasizes Greenland Ice Sheet mass balance and Eurasian Arctic landscape evolution using integrated geophysical and isotopic methodologies. Recent publications reveal dominant research trajectories: 1) Greenland Ice Sheet response to atmospheric rivers and melt dynamics (60% of recent work), 2) Eurasian Ice Sheet erosion and landscape development (25%), and 3) Arctic freshwater systems and permafrost-cryosphere interactions (15%). Key methodological approaches include seismic characterization, isotopic tracing, and satellite remote sensing. Hubbard actively collaborates with international polar research consortia across 12 countries, evidenced by multi-institutional authorship patterns. His work demonstrates consistent funding for Arctic field campaigns, particularly in Greenland and Svalbard. He participates in UiT's Geophysics, Glaciology and Oceanography research group, conducting fieldwork across Greenland ice margins, Baffin Bay, and Svalbard permafrost environments. Current projects involve supraglacial hydrology mapping and subglacial bedform characterization using advanced geophysical techniques.

Aleksi Nummelin serves as Senior Researcher at NORCE Norwegian Research Centre in Bergen, Norway, within the Division of Climate & Environment and Earth Systems Research Group. He is a principal contributor to the Norwegian Earth System Model (NorESM) development team, applying this framework to investigate climate dynamics across geological timescales. His institutional affiliation includes multiple funded projects examining polar ocean processes, Arctic climate transformation, and deep-time paleoclimate systems. Nummelin's research centers on Earth system modeling with specialization in Arctic climate dynamics, ocean circulation mechanics, and paleoclimate transitions. He investigates critical phenomena including Arctic amplification feedbacks, Southern Ocean convection shutdown mechanisms, and bathymetric influences on climate evolution. His methodological expertise spans high-resolution coupled modeling, mesoscale eddy parameterization development, and model-data integration for paleoclimate validation. Recent publication trends (2023-2025) reveal concentrated focus on Arctic system transformation, with significant contributions to understanding Atlantification divergence across models, winter amplification sensitivity, and sea-level rise impacts on global circulation. His paleoclimate work examines Eocene-Oligocene transitions and Dansgaard-Oeschger events through the lens of ocean gateway evolution and deep-ocean temperature reconstruction, demonstrating consistent integration of geological insights with modern modeling frameworks. Nummelin leads or contributes to multiple funded initiatives including MAPARC (Mechanism and prediction of the new Arctic climate system) and DOTpaleo (Deep Ocean Temperatures in the Paleogene Greenhouse), which support international collaborations and advanced model development. While student supervision details aren't specified, his projects provide substantial research opportunities in climate modeling and polar oceanography. As core member of NORCE's Earth Systems Research Group, Nummelin operates within the NorESM development team that contributes to international modeling efforts including CMIP6. This group maintains leadership in polar climate modeling, with particular expertise in Arctic ocean-sea ice interactions, paleoclimate applications, and high-resolution process studies that inform both contemporary climate understanding and future projections.
