A university lecturer plans to live stream from a mountain ditch for 24 hours to highlight soil issues and raise climate change awareness.
Miranda Whall will be in a self-dug ditch about 600m (1,960ft) up in the Cambrian Mountains in Ceredigion from Saturday afternoon.
The Aberystwyth University academic dressed as a sheep for a previous project, and likes to “bring some humour” to grab attention.
She aims to “give a voice to the soil”.
Ms Whall will attempt to vocalise a live numerical data stream from sensors in the ground around her, which measure soil moisture and temperature.
