Theme session L within ICES 2010 ASC: Spatially explicit models for plankton and fish: processes, model integration and forecasts

EUR-OCEANS endorsement

Message from the conveners of the theme session

The next Annual Science Conference of the International Council for the Exploration of the Sea will take place in Nantes, France, 20-24 September 2010. We would like to bring your attention to theme session L: “Spatially explicit models for plankton and fish: processes, model integration and forecasts”. We welcome papers on topics related to model advancements, forecasting, impacts of environmental drivers, case studies and applications. Please find the theme session description below.

The 2010 Call for Papers and Abstract submission system is now open at The deadline for the submission of abstracts is 15 April 2010. We propose to work with you and the editor of the ICES Journal of Marine Science to publish within the year a suite of peer-reviewed papers coming from conference session L.

Please join us for what we expect to be an engaging session on novel and challenging models. Also, please feel free to circulate this message to other colleagues who might be interested.

We look forward to seeing you in Nantes.

Best regards,

Pierre Petitgas, Thomas Neumann, Bernard Megrey, Myron Peck

Description of Session L - Spatially-explicit models for plankton and fish: processes, model integration and forecasts

Conveners: Pierre Petitgas (France), Thomas Neumann (Germany), Bernard Megrey (USA), and Myron A. Peck (Germany)

Coupled models of the ocean circulation and plankton continue to improve their representation of the spatial and temporal variability of the marine environment. These models provide a solid basis for describing the current state of the ocean and projecting future states. To project changes in fish distribution and productivity under global change, models of different fish life cycle stages are also being developed. Models of lower and upper trophic levels can now be integrated. This theme session targets presentations that attempt to meet current challenges faced in constructing Spatially-explicit plankton, fish and coupled plankton-fish models. Challenges faced in modelling plankton include the need to improve the representation of processes acting at very small scales, representing how the diversity of the plankton provides flexibility of the response to external forcing, including benthic-pelagic coupling, and using data assimilation to improve short-term predictability. Current challenges in spatially-explicit models for fish include the development of process models of fish movement, linking fish bioenergetics to prey fields, and integrating the full life cycle (inclusion of life cycle closure) to better estimate population-level responses o various drivers. Finally, ongoing challenges in linking spatially-explicit lower and upper trophic level models include the need for predator-prey feedback loops and the tradeoffs between the needs for biological realism and model simplicity.

In this session, presentations are welcome that focus on:

  • methodological advancements: model parameterisation, simulation platforms, novel life cycle modelling, trophic coupling strategies
  • operational forecasting: algal bloom dynamics, larval fish drift and survival
  • applied simulations examining the impacts of various environmental drivers (e.g., nutrient load and/or climate change scenarios)
  • mature applications of linked models projecting spatially-explicit trophodynamic climate impacts
