Title: LIFECO: LInking hydrographic Frontal activity to ECOsystem dynamics in the North Sea and Skagerrak: Importance to Fish Stock recruitment
Description:
Abstract:
LIFECO takes a holistic approach to the understanding of a key element of the North Sea ecosystem: resolving the importance of frontal regions, a key organising processing the marine environment, for recruitment success of important North Sea fish stocks. The influence of intra- and inter-annual climatic forcing on bottom up processes will be resolved, by developing and implementing a nested small-scale physical/biological model incorporating organism behaviour and nutrient fluxes to simulate phytoplankton and zooplankton production and aggregation relative to frontal processes. This work will allow the horizontal and vertical distribution of potential prey items for larval and juvenile fish to be simulated, as well as the inter- and intra-annual variability of these items relative to frontal processes. Simulated fields developed by the model will then be validated with state-of-the-art field and remote sensing techniques. The second key mechanism influencing recruitment success of fish stocks in the North Sea are 'top down' or predation processes. Aggregations of planktivorous and piscivorous fish species in frontal environments are common occurrences in the marine environment. A key objective in this programme is to resolve the impact of predation on the abundance of zooplankton as well as larval and early juvenile fish by planktivorous and piscivorous predators in frontal regions relative to stratified non-frontal regimes. Estimates of consumption rates and predatory impact will be obtained on basis of a multi-disciplinary field programme covering different hydrographic regimes via the analysis of stomach contents and the utilization of food web biomarkers. Estimates of mortality rates will then be developed based on the observed distributions and abundance of different species relative to water column characteristics during cruise programmes. The ecosystem approach required to address the primary goals of the programme necessitates the utilization and integration of a multi-disciplinary research strategy. Hence, the programme has been divided into 9 workpackages: 1) Advancement of hydrodynamic models: Resolution of frontal variability and key forcing processes. 2) Coupled Bio-modelling: Simulation of lower trophic level dynamics 3) Remote Sensing of Frontal Regimes 4) Distribution and abundance of plankton and fish relative frontal processes. 5) Effects of frontal processes in the plankton: resource controls and trophic interactions 6) Predatory interaction between fish species and top-down control of zooplankton relative to frontal processes. 7) Database assembly 8) GIS and Spatial Data Analysis 9) Synthesis, scenario and hypothesis testing
