PhD Fellow in Assessing the role of glaciogenic coastal sediments on marine C, N and P cycling, iC3 – Deadline 05 February 2024

The Department of Geosciences, Faculty of Science and Technology has a PhD position vacant on coastal glaciogenic sediment biogeochemistry. The position is affiliated to the newly funded Norwegian Centre of Excellence, iC3: Centre for ice, Cryosphere, Carbon and Climate.

The position is for a period of four years. The nominal length of the PhD programme is three years. The fourth year is distributed as 25 % each year and will consist of teaching and other duties for the department. This may include teaching (e.g. supervision and evaluation of student exercises) at various levels, as well as performance of other relevant duties. The objective of the position is to complete research training to the level of a doctoral degree. Admission to the PhD programme is a prerequisite for employment, and the programme period starts on commencement of the position.

The workplace is at UiT in Tromsø. You must be able to start in the position within a reasonable time after receiving the offer and latest 1st August, 2024. During the PhD the student will be expected to obtain 30 ECTs within the instruction component and 150 ECTs for the thesis component.

Centre of Excellence, iC3: Centre for ice, Cryosphere, Carbon and Climate 

The PhD fellow will be part of a cohort of iC3 fellows to start in 2024 and benefiting from iC3´s dedicated impact Theme (iT-2) Training the Next Generation which will train and mentor early career researchers under iC3´s broad remit. iC3 is funded for 10 years (2023-2033, pending successful mid-way evaluation) and aims to fill a major research gap in polar science by quantifying the future impact of ice sheet change on the Earth’s carbon cycle over policy-relevant timescales. It will achieve this by uniting complementary world-leading expertise at UiT The Arctic University of Norway, the Norwegian Polar Institute, NORCE and a network of collaborators in an unprecedented research endeavour spanning both the Arctic and the Antarctic. Its integrated, interdisciplinary hub of experts studying the cryosphere, oceans, atmosphere and geosphere will close order of magnitude uncertainty in polar carbon budgets, addressing the hypothesis that changing ice sheets (and aligned cryosphere) profoundly impact Earth’s carbon cycle, directly affecting human societies via feedbacks to our future climate and invaluable polar ecosystems.

Project details

Glaciers are highly efficient agents of physical and chemical erosion, exporting large quantities of sediment and solute to downstream environments each year. Glacial meltwaters in coastal settings are often characterized by turbid and buoyant sediment plumes that can sometimes reach 10s of kilometres offshore. The solute and sediment carried by these plumes is thought to act as direct or indirect (after biogeochemical processing) nutriment to marine organisms, but the impact appears to be dependent on the hydrodynamics of the fjord/coastal environment and the bioavailability of the particulate phase.

One component of the ice-to-ocean system that is still poorly understood is the role of benthic diagenesis in the cycling of glacier and marine derived elements in coastal environments. Recent work in Svalbard has found intense benthic cycling of glacier-sourced iron and manganese in these reactive sediments, and global synthesis of fjord data indicates that these environments are globally relevant carbon burial hotspots and aquatic critical zones. However, our understanding of linked (e.g. via coupled cycling or mineral association) but often limiting macronutrients phosphorus and nitrogen is still poor due to a paucity of data. For example, a large portion of the phosphorus carried by glacial meltwater is bound in the mineral apatite, which is not immediately available for biological uptake, but may become bioavailable after dissolution in coastal sediments. Additionally, we do not know if glaciogenic sediments in active glaciated environments such as Svalbard, Greenland and Antarctica are carbon sources or sinks, and how carbon in these sediments might couple with other elemental cycles (e.g. via iron mineral association or clay mineral protection).

This PhD project will aim to contextualize the importance of glaciogenic marine sediments for carbon, nitrogen and phosphorus cycling in polar regions. The candidate will work on glacial flour (glacially ground rock) and coastal sediment biogeochemistry, including selective chemical extractions to identify phase speciation, mineral binding, and lability of nutrient/carbon pools. Glacial flour and coastal sediment cores are available from Svalbard, Greenland, and Antarctica, but there will be opportunities to collect new cores as part of iC3 associated field campaigns. The candidate will characterize both pore waters extracted from cores as well as the particulate phase in core material and in glacial flour to gain a detailed insight into systems inputs, particle-solute coupling, and benthic fluxes of nutrients into the water column. The project will look to help answer the question: how will nutrient and carbon cycling in these climatically sensitive environments change with waning glacier cover?

The project objectives are as follows:

  • Determine the sources, sinks, mineral association and associated lability of C, N and P in fjord sediments
  • Investigate environmental controls on fjord benthic C, N and P cycling across an ice to shelf transect
  • Develop a spatial dataset of C, N and P concentrations and fluxes from sediments across Arctic and Antarctic field sites

Opportunities: the project offers a wide range of lab, field, and computer-based numerical modelling opportunities dependent on the candidate’s interests. Initial work will be carried out on existing cores taken from Svalbard, Greenland and Antarctica, but there is potential for Arctic fieldwork in Svalbard (Kongsfjorden), and/or west/south Greenland to retrieve new sediment cores for porewater and sediment analysis as part of iC3. The student will have access to cutting-edge instrumentation in Norway (via UiT) and the United States (via U Penn), including ICP-MS/MS, nutrient (e.g. SFA), and carbon analysers (dissolved, total, thermal characterisation, and optical characterisation), have opportunities to apply for experimental time at synchrotron facilities in Europe and North America (e.g. for C, N and P speciation via scanning x-ray microscopy, x-ray absorption near-edge structure spectroscopy and x-ray fluorescence elemental mapping at the nano scale), and a wide range of institutional and collaborator accessible instrumentation for sediment particle characterization (e.g. SEM, TEM, FIB and XPS) and high resolution organic matter compositional analysis (e.g. via FT-ICR MS). This project comes with the possibility of a secondment to University of Pennsylvania (Philadelphia, USA) for lab work and data analysis (via Dr Hawkings), and/or Universite Libre de Bruxelles (Brussels, Belgium) for training in diagenetic reaction-transport modelling (via Dr Arndt).

The position’s field of research

While the candidate is a member of the iC3 Centre of Excellence, they will be employed at the Department of Geosciences, at UiT´s Faculty of Science and Technology.
