Staff profile

Susa Niiranen’s research focuses on change in marine ecosystems that is driven by multiple environmental and anthropogenic stressors

Profile summary

  • Marine ecosystems
  • Food web dynamics
  • Ecological modelling
  • Multiple drivers
  • Environmental change
  • Baltic Sea
  • Arctic marine systems

The main focus of Niiranen’s research is on marine food web dynamics and how they respond to changes in multiple environmental and anthropogenic stressors. She uses modelling as her research tool and is currently working with a size-structured food web modelling approach in a Baltic Sea Bonus project BlueWebs. Her recent research also includes study of cross-scale dynamics in Arctic marine systems. Niiranen is a co-lead of the Marine Theme at the Stockholm Resilience Centre.

Niiranen has a PhD in marine ecology from the Department of Ecology, Environment and Plant Sciences (DEEP) at the Stockholm University. For her PhD research she studied how multiple interacting drivers affect the dynamics of Baltic Sea food web. She holds an MSc in hydrobiology from the University of Helsinki and worked at the former Finnish Institute of Marine Research and the Baltic Nest Institute before her becoming a post-doctoral researcher at the SRC. While at SRC, she has worked in projects GreenMAR, INSPIRE, and BlueWebs.

Niiranen participates actively in the work of the International Council of the Exploration of the Seas (ICES) expert groups such as the Working Group on the integrated assessment of the Baltic Sea (WGIAB) and Working Group on Comparative Analysis between European Atlantic and Mediterranean marine ecosystems (COMEDA).

Global ensemble projections reveal trophic amplification of ocean biomass declines with climate change

Lotze, H.K., Tittensor, D.P., Bryndum-Buchholz, A., Eddy, T.D. et. al.

2019 - Journal / article

While the physical dimensions of climate change are now routinely assessed through multimodel intercomparisons, projected impacts on the global ocean ecosystem generally rely on individual models with a specific set of assumptions. To address these single-model limitations, we present standardized ensemble projections from six global marine ecosystem models forced with two Earth system models and four emission scenarios with a...

A participatory scenario method to explore the future of marine social‐ecological systems

Planque B., Mullon C., Arneberg P., et.al.

2019 - Journal / article

Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective is to allow different ac...

Ecological and functional consequences of coastal ocean acidification: Perspectives from the Baltic-Skagerrak System

Havenhand, J.N., Filipsson, H.L., Niiranen, S. et al.

2019 - Journal / article

Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, organisms and ecosystems. Substantial recent advances reveal a pattern of stronger responses (positive or negative) o...
