Cod-haddock individual-based modelThe mechanistic feeding component uses biological and physical properties of predator, prey, and environment for calculations
• Day 1 – Plenary talks: politicians, scientists, end-users
• Day 2 – Working Groups – Intermixing of pre-selected task-oriented groups
Sensor and platform development Data integration and modeling. End user interface
• Day 3 – Working Groups – Develop end-to-end prototypes by task-oriented groups

BASIN: Basin-scale Analysis, Synthesis, and Integration - Resolving the impact of climatic processes on ecosystems of the North Atlantic basin and shelf seas.
Goal: To understand and predict the impact of climate change on key species of plankton and fish, and associated ecosystem and biogeochemical dynamics in the North Atlantic Subpolar Gyre System and surrounding shelves, in order to improve ocean management and conservation.
