The Quality Status Report 2010 – the QSR 2010 – is a milestone for evaluating the quality status of the North-East Atlantic and for taking forward OSPAR’s vision of a clean, healthy and biologically diverse sea. It follows up on the previous quality status report – the QSR 2000 – as well as earlier QSRs specific to the North Sea. The QSR 2010 reflects the collective effort made by Contracting Parties over the period 1998 to 2008 to manage, monitor and assess the many pressures on the diverse ecosystems of the North-East Atlantic and the impacts that they bring.
