Marbh Crhios (Dead Zone) is a multimedia artwork, part of the Lovely Weather Donegal Residencies Project, that reflects upon climate change in the context of a local community in Killybegs in County Donegal, Ireland. The work was based on scientific data about contested marine ‘dead zones’ that the authors represented with algorithmically generated music, sonifications and visualizations in a live performance in Mooney's Boatyard in Killybegs, involving three local ensembles.
