Resource or Project Abstract

*** Small-scale Study Report - see note under Supplemnentary Information ***

The primary aims of the EU Water Framework Directive 2000/60/EC (WFD) are to improve, maintain and restore good water quality for all water bodies by 2015 (Anon, 2005). Of critical importance to realising these aims is an understanding of aquatic ecological pressure-response relationships. Understanding ecological pressure-response relationships in freshwater ecosystems requires the analyses of long-term monitoring data, which is often absent or only covers relatively short timescales. Mathematical modelling provides a powerful means of examining long-term ecological pressureresponse relationships. Palaeolimnology, involving sediment-based proxies of environmental conditions, can also help elucidate long-term ecological pressures-response relationships and could potentially be used to validate modelled aquatic ecosystem pressures and responses.
Through a novel approach that integrates modelling and palaeolimnological techniques, an aquatic ecological response model (DYRESM-CAEDYM) was validated for Lough Mask, Co. Mayo. Hindcast daily simulations of in-lake responses (including nutrients, chlorophyll and phytoplankton) were produced and compared with sediment-based reconstructions of in-lake TP concentrations. Both the hindcast and sediment datasets compared well, highlighting the potential for sediment-based DI-TP to be used validation of hindcast in-lake TP concentrations. Furthermore, results indicate that sediment-based proxy data can also help explain model limitations, for example, mechanisms not incorporated in models.
Results from this small study demonstrated how a combined dynamic aquatic ecosystem modelling and palaeolimnological approach can provide valuable insight into aquatic pressures-responses relationships. This research also indicates that the effectiveness of the combined palaeolimnological and dynamic modelling approach is strongly dependent on the resolution of sediment-based data and, in general, relatively high and undisturbed rates of sedimentation are of key importance to the application of this approach. However, this study shows that even in the case of relatively low resolution palaeolimnological data the combined palaeolimnological and modelling approach can provide a useful means of verifying output from and exploring the limitations of aquatic ecological response models.
