Oceanography & climate: Monitoring of physical oceanographic parameters for the assessment of climatic influences on fish stocks in the North Sea Atlantic and North Atlantic
Project
Project code: vTI-SF-08-15
Contract period: 01.01.2001
- 31.12.2020
Purpose of research: Applied research
As a result of global climatic changes, distribution areas and population dynamics of North Atlantic fish stocks are changing. This has impacts on the utilisation of these stocks by the fishing industry. Long-term time series of oceanographic parameters around Greenland reveal significant correlations with changes in fish stocks. In the North Sea, the climatic signal is weaker and so far only detectable in southern regions of the North Sea. Correlation of climatic parameters and distribution pattern of fish species are discussed. The institute performs oceanographic measurements on all fishery biological research cruises. The validated data sets are delivered to national oceanographic data centres (DOD/MUDAB) and international databases (ICES, WDC). Modelling interactions between climatic data sets (ocean, atmosphere) and biological observations and fish stock changes enables the establishment of criteria for climatic induced biological variation.
Coupling of hydrographic measurements and model data to investigate the influence of variable hydrographic conditions on population dynamics of fish stocks in the North Sea and North Atlantic To identify and quantify important processes in the complex system 'Climate-Ocean-Fish', determine temporal and spatial scale of the interactions between marine organisms and their environment. New insights into the influence of the North Sea hydrography (temperature and salinity) on stock biomass and recruitment of commercially important fishes Case study about the influence of the temperature and ocean currents on spatial distribution of redfish in the North Atlantic New findings about daily vertical migration of Antarctic planktonic organisms Working group documents in ICES and NAFO working groups.
