Estimation of biomass production in lower trophic ocean levels

As part of continuing efforts to improve management of resources and sustainable fisheries, the EU has supported research into improving understanding of marine resource systems, notably through the ACP-EU Fisheries Research Initiative. Whilst significant progress has been made in modelling the biomass and abundance at higher trophic levels, less attention has thus far been given to the lower trophic levels and primary producers in the ocean.

The Commission is therefore seeking an organisation to undertake a study to estimate primary production in the ocean on a global scale, including the possibility of refining the estimate at selected regional levels. The methodology will be expected to make extensive use of the latest generation of remote-sensing satellite data and existing databases of bio-optical data. The highest priority is the global aspect, and the integration of global estimates into ecosystems will be one of the methods through which the applicability of the global primary production will be assesses.

The study contract, to be completed by 31 December 2000, will include:

- The development of concepts and methodology for estimation of primary production on a global scale;
- A protocol for extrapolation of local algorithms to large-scale application in areas of scarce in situ data;
- Proper validation of the end products;
- The production of primary production estimates for specific regions and their dissemination;
- The capacity of injecting primary production estimates into FishBase and ecosystem models such as EcoPath and EcoSim.
