PhD project title:

Arctic ocean hydrography and circulation during the last interglacial period through the development and application of new proxy methods.

PhD project description:

I am currently working towards a PhD within the Arctic Ocean under warm climates (ARCLIM) group, headed by Mohamed Ezat. My research is focused on the use of foraminifera as a proxy for reconstructing surface and bottom water hydrography in (sub)polar regions. Foraminifera are a microscopic single-celled marine organism, ubiquitous across the world’s oceans and can be both planktonic, floating in near-surface water, or benthic. I am growing the species Globigerina bulloides in culture to investigate how the incorporation of chemical elements in its calcium carbonate shell changes under different environmental conditions (varying salinity, temperature, pH etc). The results of the culturing experiments will be applied, in combination with other foraminifera proxy data, to fossil shells from interglacial sediments and used to reconstruct sub(polar) ocean conditions during warmer than present time periods. The increased understanding of sub(polar) warming this brings can then be applied to models used for predicting future ocean conditions.

Start date: 21.11.2021
Planned submission date: Autumn 2025

PhD project title:

Modeling the concentrations and structure of plankton and particles in the Spitsbergen coastal waters under different scenarios of environmental changes.

PhD project description:

The main aim of my PhD project is to recognize the future functioning of the Arctic marine pelagial affected by intensified glacier and glacier-fed rivers runoffs in Isfjorden, Hornsund and Kongsfjorden. The Arctic coastal waters are biologically rich and essential both for marine life and  fisheries, however the impact of the fresh, highly turbid waters on primary and secondary production is still unknown. Because significant spatial differences along fjord axis, from glacier fronts to the outer parts, have been previously revealed with regard to suspension loads and sedimentation rates, phytoplankton and zooplankton, it is possible to infer about their interactions. Thus, in order to estimate how areas with different extents of freshwater runoff shape coastal marine communities, I will combine hydrography, optics and plankton ecology together with trophic interactions consideration. Such a broad interdisciplinary research will provide a data set for modelling estimations.

Start date: Oct 2019
Planned submission date: Oct 2023
