Arbeidsområde
I am currently working on a 3-years Postdoctoral research fellow project (2019-2022) where the aim is to i) develop an individual based model (IBM) for Calanus glacialis within the NORWECOM.E2E model system, and ii) investigate the impact of expected future ocean climate conditions on lower trophic levels in the Barents Sea.
Copepods of the genus Calanus are predominantly herbivores and dominate the zooplankton biomass in high latitude ecosystems where they form a key link between primary production and higher trophic levels. With an individual lipid content of up to 50–70 % of the body mass, these species constitute key food sources for planktivorous fish, seabirds and mammals in the Barents Sea. Climatic conditions in the Barents Sea are changing dramatically, and the sea is getting warmer. Recent studies from the Nansen Legacy project predict a complete loss of sea-ice within the year 2050. Plankton dynamics are tightly linked to ocean climate conditions, and changes at the base of the food web may propagate through the ecosystem with consequences at multiple scales. With the development of a C. glacialis IBM module, the NORWECOM.E2E model system will encapture the two major herbivorous zooplankton species within this ecosystem, thus enhance our ability to predict future zooplankton dynamics in a warmer Barents Sea.
The postdoc-position is part of the Nansen Legacy project (www.arvenetternansen.no) financed by the Norwegian Research Council.
