Ulrike is a PhD student at UiT – The Arctic University of Norway since 2017, studying sea ice ecology in the seasonal ice zone. She is interested in the interaction of microorganisms with their environment and their importance for higher trophic levels, especially in the scenario of extended periods of no ice. She enjoys spending endless hours in the field and lab. Previously, she has studied gel particles within Arctic sea ice and their bacterial colonization. Her research has taken her north of Svalbard, the Fram Strait and Kongsfjorden.
Raphaelle is a PhD student at UiT – The Arctic University of Norway studying benthic ecology in the seasonal ice zone. She is interested in biodiversity and its relationship to environmental conditions in high-latitude ecosystems, especially in the context of widespread environmental changes. She loves spending time in and on the water, the colder the better! She has previously studied marine invertebrates in Canada and Alaska, often focusing on the larval stages. Raphaelle also enjoys sharing her passion for the oceans with audiences of all ages and backgrounds through outreach and education activities.
Christine is a PhD student in arctic and marine biology at UiT – The Arctic University of Norway. She has a B.Sc. from McGill University in Canada, where she worked in a behavioural ecology lab, and received a M.Sc. from UiT – The Arctic University of Norway where she studied vertical carbon export during bloom events under sea ice north of Svalbard. Christine’s research interests focus around pelagic-benthic coupling, and in understanding how vertical export of organic material varies around the seasonal sea ice zone, especially with regard to climate change. She hopes to gain further insight into the composition of sinking material and the associated grazing activity by key zooplankton species.
Tobias R. Vonnahme
Tobias R. Vonnahme is a PhD candidate at UiT – The Arctic University of Norway since 2017. His research interests are the structure, fluxes and controls in microbial food webs in sea ice ecosystems and deep-sea sediments. He focuses on biogeochemical cycles and microbial community structures and functions. He has a background in bioinformatics, modeling, and microbial ecology. He has been working on Svalbard fjords and glaciers and the central Arctic Ocean on sea ice and glacier ecosystems since 2014.
