Dynamics of marine ecosystems under past, present and future climate

Future climate variability and change will impact the entire range of physical & biogeochemical variables and processes in the ocean.

These changes are expected to influence the marine ecosystems through productivity changes, displacement of species and changes in trophic structure and species diversity. The Hjort Centre explores how past interannual to multidecadal climate variability has impacted productivity and distribution of plankton and fish, and identifies key physical forcings for ecosystem productivity. Ecosystems response to future climate is studied and predicted by developing and applying mechanistic, evolutionary and life-cycle models coupled to physical-biogeochemical models. How ecosystem based management should adapt to future climate is another focus area.

FRAM Flaggskipet Havforsuring og økosystemeffekter i nordlige farvann.
WP3: Coupled climate-ecosystem-acidification modeling from organism to basin
Project leader: Philip Wallhead (NIVA), Morten Skogen (IMR)
Funding source: KLD
Period: 2015-2017
The purpose of this initiative is to produce an improved understanding of future Arctic OA, ecosystem responses and feedbacks under a changing climate, and to facilitate predictions of local and regional effects of OA on invertebrates and ultimately fish.

BIGCHANGE: Biogeochemical change and detection
Project leader: Are Olsen (UiB), Jerry Tjiputra (Uni Research)
Funding source: Bjerknes, SKD
Period: 2015-2018
Description: To improve our ability to detect future climate change and impacts as they start to unfold by: (1) furthering understanding of processes operating in the Atlantic and Arctic regions under various climate forcings and their respective carbon cycle imprint and (2) identifying regional biogeochemical hotspots and periods of emergence by using rigorously optimized and observationally-calibrated model projections.
