Day 1
Session 1: Analytical methods for detecting changes in spatial distribution

Welcome, introductions
Overview of goals and objectives of WKSICCME-Spatial

William Cheung (Canada, Invited)
Projecting climate change effects on the distribution of global fish stocks

[pdf, 1 Mb]

Breakout group assignments
Session leaders: Franz Mueter (USA), William Cheung (Canada), Brian MacKenzie (DK)

  • What types of statistical methods and summary measures (e.g., spatial gams, simple means, bio-climatic windows, centroids, other) have been employed to quantify changes in distribution? What are the strengths and weaknesses of these methods?
  • What dynamic simulation methods have been applied to forecast changes in distribution? What are the strengths and weaknesses of these methods?
  • What mechanisms can explain observed shifts in distribution? How can these mechanisms be implemented in predictive models?
  • Can observed shifts be attributed to climate variability and / or climate change? Is it possible to disentangle the effect of fishing from the effects of climate variability and change?
  • What additional data, process studies, and theoretical developments would help to resolve the mechanisms and their functional form?
  • If you had the funds and international agreements what type of experiment would your group develop to assess projection skill, resolve mechanisms, and enhance our ability to evaluate attribution to climate variability and change?

Plenary discussion action plan, key data gaps and key recommendations

Session 2: Skill Assessment and model inter-comparison

Miranda Jones (UK, Invited)
Applying a multi-model approach to predicting species' distributions

Shin-ichi Ito (Japan, Invited)
How to model fish migration and distribution under future climate?
[pdf, 5.4 Mb]

Breakout group assignments
Session leaders: Miranda Jones (UK), Mark Payne (DK), Enrique Curchitser (USA)

  • Have skill assessments (statistical comparison of observed and predicted spatial distributions) been performed?  Identify regions and describe the methodology?
  • Climate impacts differ by life stage and the impacts are compounded over time.  Which life stages that should be used to assess predictive skill with respect to shifts in spatial distributions of the resource and fisheries?
  • Should we consider developing "best practices" guidelines for skill assessments?
  • Identify regions where more than one projection modeling approach has been conducted.  How different were the projections and why?
  • What are the pros and cons of adopting a multi model projection approach to dynamic population models?
  • What initiatives should ICES and PICES advance to facilitate progress on skill assessment and model inter-comparison?


Day 2
Plenary Discussion action plan, key data gaps, and key recommendations (10 minutes each)

Breakout group assignments
Session leaders: David Reid (Ireland), Emanuele Di Lorenzo (USA), TBD (USA)

  • What are the key sources of uncertainty in GCMs or ESMs?
  • Can your group agree on a single best practice for use of GCM or ESM outputs in projecting distributional shifts of marine species? If not, why not?
  • What are the key sources of uncertainty in dynamic population models? How are these errors addressed in studies of shifts in spatial distribution? 
  • How should key uncertainties be incorporated into projections?
  • What can ICES and PICES do to improve collaboration between marine ecosystem modelers and earth system modelers?

  • What are the relevant datasets available for use in documenting climate induced shifts in spatial distribution of fish, shellfish and their fisheries? Is this information available on-line either through a public or password protected site? What are the best data delivery systems?
  • To what extent are the relevant datasets compatible in time and space scales to the physical observations and model data sets that define climate change?
  • In transboundary stocks have methods been established to correct for differences in sampling methods?  What options are available to make these corrections?

  • What products can ICES and PICES deliver to decision makers and their constituencies?  If products are delivered, how will the quality and effectiveness of the products be assessed?
  • What form of information is needed for decision making? (e.g., decision tables, risk analyses, decision theoretic approach, verbal models, interdisciplinary explanations)
  • What range of management actions could be considered? How could information products be designed to help managers to make informed choices in the future?
