PhD project title:
Phenology of life cycles in benthic invertebrates of the Arctic seasonal ice zone
PhD project description:
Waters advected into the Arctic from sub-Arctic seas carry nutrients and living organisms which can have important repercussions for the benthic communities of the Arctic. Many marine benthic invertebrates release planktonic larvae which can drift with water currents. Because of their long residence time in the water column, some planktonic larvae have the potential to disperse over long distances before settling to the seafloor. This implies that sub-Arctic species can potentially reach the Arctic during their larval stages, though not all find suitable conditions to settle and live to adulthood there, at least not yet. In light of the ongoing ‘borealization’ of biota and food webs and ‘atlantification’ of hydrographic conditions in the Arctic inflow areas, my research aims to determine whether sub-Arctic species are currently entering the Arctic at the larval stage and surviving to the juvenile stage. I am using molecular methods to identify the larvae and juveniles which are difficult to identify morphologically and to characterize their diet.

PhD project title:
Autonomous Surface Vehicles (ASVs) equipped with broadband echosounders as survey platforms for an undisturbed epipelagic layer in the Arctic.
PhD project description:
I am exploring ways to increase our understanding of the epipelagic ecosystem by complementing traditional survey methods with ASVs equipped with broadband echosounders.

PhD project title:
What sinks? Patterns and species composition of downward carbon export in a changing Arctic seasonal ice zone
Project description:
As the Arctic seasonal ice zone is experiencing rapid changes in thickness, drift and cover duration, subsequent changes are expected in the coupling between the ice and the pelagic realms. My PhD project will aim to track changes occurring on the species level in ice algae, phytoplankton and zooplankton and their relative contributions to vertical carbon export from the sea ice and under ice waters and out of the euphotic zone. Together with the other members of the Arctic SIZE project, we aim to get a comprehensive understanding of seasonal ice covered ecosystems in the northern Barents Sea and Svalbard region.
