RU3: Ice sheets and the oceans
Most water from melting ice sheets will eventually end up in the sea, but it is unclear how this will affect the oceans and the many life forms that inhabit them.
To answer this question, we are conducting research in coastal areas, on icebergs and in the seas across Svalbard, Greenland and Antarctica, using drones, ice drills, ships, and submarines to gather data. We are assessing and modelling the impacts of nutrients, methane and carbon borne by glacial meltwaters on ocean carbon stores and ecosystems.
Our aim is to drive major breakthroughs in the understanding of ice sheet impacts on ocean carbon cycles and ecosystems.

Dr Philipp Assmy
RU3 Research Lead
Philipp Assmy is a researcher at the Norwegian Polar Institute, specializing in phytoplankton ecology, sea ice biology, and ocean biochemistry. His work primarily focuses on understanding the complex interactions between ice and ocean systems and their impact on marine ecosystems, particularly in the rapidly changing Arctic and Antarctic regions. With the Arctic warming significantly faster than the global average, Philipp's research is crucial in deciphering the implications of these changes on marine life and the biological carbon pump, a vital process for sequestering atmospheric carbon dioxide. Philipp's approach is observational, involving extensive fieldwork to collect samples and data for analysis. He collaborates closely with experimentalists and modelers, leveraging a broad network of researchers to enhance the scope and impact of his studies. His research spans both poles, with a strong emphasis on the Arctic, including areas like Svalbard and the central Arctic Ocean. He also maintains active collaborations in Antarctic research, building on his earlier work in the Southern Ocean. Philipp is particularly excited about advancements in genomics, big data and remote sensing, which offer new insights into plankton processes and help extrapolate findings from limited samples. These technologies are instrumental in understanding the role of diatoms in polar regions, which are key drivers of the biological carbon pump. Despite the challenges of limited in-house analytical facilities, Philipp's work is supported through strategic collaborations and partnerships. At the Norwegian Polar Institute, Philipp enjoys a collegial and diverse work environment that fosters collaboration across various scientific disciplines. Outside of his scientific pursuits, he finds relaxation and inspiration by spending time in nature, particularly enjoying fishing trips on his boat in the fjords.

Fanny Cusset is a dedicated scientist, specialized in marine ecology and ecotoxicology. Currently a postdoctoral researcher at the Norwegian Polar Institute (NPI), she is involved in the iC3-affiliated project “METALLICA”, which investigates the release of metals from glaciers and their impact on marine ecosystems in Arctic fjords. Focusing on Svalbard, her research examines how toxic metals bioaccumulate in marine biota, from primary producers to top predators, as well as the drivers of metal contamination in a changing Arctic. Understanding the ecological consequences of glacial melt on Arctic ecosystems and resources is crucial for informing conservation strategies today and in the future. Fanny's academic journey began in Marseille, France, where she pursued a Bachelor's degree in biological oceanography. She expanded her expertise in Canada at Laval University, engaging in Arctic research that explored the relationships between sea ice and marine life, using stable isotopes and lipids as ecological tracers. Her master's and PhD work further delved into marine ecology and ecotoxicology, with a focus on mercury contamination in remote oceans and how seabirds can act as bioindicators of global marine ecosystems. Beyond her scientific pursuits, Fanny has taught at various institutions and participated in Arctic Ocean cruises, gaining diverse experiences in polar research. Her passion for marine science was sparked by an early fascination with whales, which continues to inspire her work today.

Freya Sykes is a marine geoscientist working at the department of Geoscience at UiT the Arctic University of Norway. Affiliated member of iC3, she delves into the impacts of climate change on the Nordic seas. Her research primarily focuses on understanding the influence of global warming on North Atlantic water masses and currents at subpolar to polar latitudes. She utilises the microscopic plankton, foraminifera by whose calcium carbonate shells record sea water properties at the time they were living. Analysing these shells can provide insight into historical climate change. This crucial work aids in predicting future climate scenarios, particularly how they might influence oceanic currents and, by extension, global climate patterns. Freya's passion for her field extends beyond the lab. She frequently participates in research cruises, gathering data firsthand and experiencing the dynamics of marine environments. This hands-on approach not only enriches her research but also fuels her love for the ocean. Outside of her professional life, Freya is a keen sailor and knitter, a practical combination for polar adventures.
