DC6 Klara Köhler MAY 24 - OCTOBER 24 

Month 13: In May 2024, I spent a lot of time preparing for the fieldwork, i.e. preparing and packing the scientific equipment and meeting with the team to plan our work in the field. I also participated in an AI workshop for academic research and writing at our department and joined the first planning meetings for fieldwork in 2025.

Month 14: In June 2024, I spent most days in the lab conducting nutrient analysis for samples for my first paper. The samples were incubated sediment-water samples from 2022, taken in Greenland, and I looked into the nutrient concentration dissolved in the water and bound to the sediment. I also completed the PhD course ‘Science Teaching’ at our campus in Aarhus.

Month 15: July 2024 was filled with our field work in Kangerlussuaq, Greenland, where I stayed for three weeks. I took basal debris (debris transported with the ice, melting at the margin of the glacier out of an almost black band on the glacier (see photo)), proglacial sediment, rock and water samples at the margin of the Russell Glacier close to Kangerlussuaq. Further, I had the chance to take additional water samples along the river and the Kangerlussuaq Fjord.

Month 16: In August 2024, we organised the transport of the frozen and cooled samples back to Denmark. I also started analysing the data from the lab session in June 2024, attended department meetings and took over the chair of our Equality and Diversity Committee for the next ~6 months.

Month 17: In September 2024, I wrote my progress report for our PhD school. In parallel, I started writing my first paper and started reviewing the written parts with the co-authors. For three days in September, I participated in the PhD course ‘Gender in Science’ at Malmö University, where I prepared a presentation and a written report in addition to the course days. At the end of September, I helped organise our PhD Bundle Meeting, a meeting for all PhD students in our department.

Month 18: In October 2026, I finalised the progress report for the PhD school. One week in October, our IceBio network meeting took place in Copenhagen, where we learnt about writing skills, outreach and advisory work. At the end of October, I attended the Nordic Branch Meeting, an annual conference of the Scandinavian branch of the International Glaciological Society (IGS).

DC7 MARCO AJMAR AUG 24 - OCTOBER 24 

Month 13: In  August, I tested dissolved silica, pH, turbidity, conductivity and dissolved oxygen sensors in Potsdam lake. This was followed by two weeks of  fieldwork in Iceland sampling two different glaciers and a glacier fed river (twice). In addition to that, the aforementioned sensors were deployed at three different locations along the river for 24 hours each time.

Month 14: In September, I processed and organised samples from my Iceland fieldwork. I extracted DOM and received training on ICP-OES analysis. I also prepared and sent samples to University of Leeds for ICP-MS analysis.

Month 15: October focused on analysis of DOC and sensor data. I prepared and analysed samples for oxygen isotopes and gave a presentation about my research project in a section meeting. Finally, I participated in the third IceBio meeting in Copenhagen.

DC5 ANIRBAN MAJUMDER JULY 24 - DECEMBER 24 

Month 13 (July 24): This month primarily focused on fieldwork in Kangerlussuaq, Greenland, which started on July 12 2024. Over a two-week period, I conducted sample collection from the Greenland Ice Sheet.

Month 14 (Aug 2024): The fieldwork was completed on August 11 2024, after which I began preparing my one-year transfer or mid-term report, marking the completion of the first year of my PhD.

Month 15 (Sept 2024): This month was primarily dedicated to preparing for my PhD transfer day. Also, I worked on my first paper and shared it with the co-authors for their feedback and comments.

Month 16 (Oct 2024): At the start of the month, on October 1st, I presented my one-year PhD transfer report. Following that I attended a network meeting of IceBio held in Copenhagen, Denmark. The program was structured into several components: 1) Scientific Writing Skills, 2) Communication with the Non-Academic World, and 3) Preparation of Science-Based Policy.

Month 17 (Nov 2024): This month was focused on lab work, during which I analyzed samples using mass spectrometry in collaboration with our partners and obtained crucial data for my PhD research. Additionally, I began preparing the documentation and logistics for the upcoming Svalbard 2025 fieldwork. I also received feedback on my first paper and worked on incorporating the suggested revisions. In the final week of the month, I initiated DNA extraction from various fieldwork samples.

Month 18 (Dec 2024): I continued DNA extraction in the lab while simultaneously preparing for the Svalbard fieldwork. Towards the end of the month, I received the Greenland 2024 fieldwork samples, which are scheduled for processing in the upcoming months.

DC8 SILJE WAALER AUGUST 24 - JANUARY 25 

Month 13 (Aug. 24): During August the last field campaign was finished in Kongsfjorden with the second fjord transect. Samples for methylmercury and total mercury were shipped to collaborators in Trondheim (NTNU). During this month I also supported the field work of Postdoc. Gabby Kleber (UNIS/UiT), in Van Mijenfjorden, Svalbard doing both marine and terrestrial sampling.

Month 14: In September the iC3 Field School pre-workshop and the following field campaign were conducted in the Lyngen Alps and Storfjorden. Here the goal was to gain knowledge on a broad variety of sampling techniques used in terrestrial and marine sampling. The aim was to capture the glacial signal in the ice to ocean continuum. The course ended with a written report on a chosen topic. I chose to focus on how deglaciation affects the export of silica to downstream systems and how that interferes with phytoplankton community composition. The experiences gained through this course will be useful when analysing the data collected in Kongsfjorden this summer.

Month 15: October was spent mainly on a mandatory philosophy and ethics course provided by UiT. Here various philosophical discussions were done in smaller interdisciplinary groups, which provided great insights into the perspectives but also all the biases all humans contain. Moreover, two presentations on philosophical topics and how our own research project relates to ethics were done. A final essay on a chosen philosophical question was conducted. In October the third ICEBIO gathering was happening in Copenhagen, Denmark, at Aarhus University at Emdrup. Here several presentations were done and the outline for the first paper was discussed among DCs and PIs. Moreover, the week contained several seminars on communication presented by a broad variety of organisations and institutions.

Month 16: In November the two reports associated with the iC3 Field School, and the Philosophy and Ethics course were finished. Moreover, two outreach presentations were conducted. One presentation was related to the Science Days in Tromsø (10min) and was targeting how climate impacts our health. I chose to talk about glacial flour in general and how some glacial flour can contain toxic trace metals that can potentially impact the health of humans and wildlife. The second presentation was related to Inspiration Days, which is a part of Arctic Frontiers’ Science for Schools program aiming to inspire school children to do science (45min). During this presentation I told the audience how I ended up in science, what I am studying and why I enjoy my life as a PhD student. Moreover, in November I managed to get a blogpost published in EGU’s CryoAdventures Blog on my first glacial field work at the Sulitjelma/Salajekna glaciers.

Month 17: During December lose ends before Christmas break was tied up with the finalization of my upcoming visits to NTNU, Trondheim and BAS, Cambridge. Moreover, a meeting with our collaborators of CIIMAR was conducted were the possibilities for metagenomic analyses of samples from Kongsfjorden were discussed. December was also spent on writing my first deliverable for ICEBIO in collaboration with Klara Kohler and Kara Sampsell on the topic of glaciers and glacial flours ability to fertilize downstream ecosystems. In this period, I also contributed to a policy brief of glacial flour and a paper for Frontiers - Young Minds.

Month 18: In January 2025 the visit to NTNU was done with the aim of analysing our total mercury and particulate mercury samples collected in Kongsfjorden 2024 in collaboration with Postdoc. Sarah Tingey, Postdoc. Fanny Cusset and Postdoc. Stephen Kohler. I also attended the Arctic Frontiers conference in this period. The last part of January was spent on getting ready for my visit to BAS in February.

DC8 ANNIKA MORISCHE AUGUST 24 - JANUARY 25 

Month 13 (Aug. 24): Debriefing of the fieldwork, including unpacking, organizing, and cataloguing the collected samples. A revision of the sample processing strategy was undertaken to optimize metabolome extraction workflows. This phase also involved preliminary quality control checks on the samples and refinement of experimental protocols to ensure robust data acquisition in the upcoming months.

Month 14: Initiation of mass spectrometry imaging (MSI) research with a focus on single-cell process imaging and its integration into the 13C-incubation experiments. A literature review was conducted to explore cutting-edge MS imaging techniques capable of resolving metabolic activity at the single-cell level. The aim was to evaluate how these technologies could be employed to reveal autotrophic metabolic processes and spatial metabolite distributions in ice algae.

Month 15: Participation in the ICEBIO network event, which included specialized training in science communication through the "Communication Toolkit and Policy Advice" workshop. This was followed by the preparation of a first conference poster presenting initial findings on the metabolic stress response of glacier microbiological communities.
