CENSOR: Climate variability and El Nino Southern Oscillation: Implications for natural coastal resources and management
To achieve this goal, CENSOR pursues a multidisciplinary approach, including research on coastal benthic communities, pelagic-benthic processes, continental riverine input to the coastal system and ecophysiological constraints and aquacultural demands.
The particular objectives of the CENSOR work package at GFZ Potsdam are:
- Quantification of the continental hydrological cycle for the Pacific river basins of Peru and Northern Chile
- Set up of a large-scale hydrological water balance model for the entire study area, based on WASA (Model of Water Availability for Semi-Arid Environments) (Güntner & Bronstert, 2004)
- Estimation of freshwater transport from the continental area to the coastal marine ecosystem
- Analysis of the variability of the hydrological behaviour as a function of ENSO
- Figure: Correlation and regression of the NINO3.4 index with the total water storage of the region of Ecuador, Peru and Northern Chile from an ensemble mean of 4 simulations with WGHM (period 1961–1994, with a time lag of 0, 2, 4, 6, 8 and 10 months (positive lag means NINO3.4 leads the water storage). Shaded information represent correlation (contour intervall: 0.1), contour lines represent regression (contour intervall: 5 mm water equivalent) (from Stuck et al. 2006).
