‘Ghost Strata’ refers to the missing elements from within the rock strata that despite their absence offer hints of what was once there. Ben Rivers' film is divided into the months of the year in which the footage was captured and features found sound and text that create a meditation on time, memory, leftovers and extinction.

This screening will be preceded by two short films from filmmaker Mark Jenkin (Bait, Enys Men) - Dear Marianne, a travelogue about a Cornishman visiting the Irish coast, and The Road to Zennor, a doc focused on the long shadows and peaceful hum of a late Cornish autumn.

Screening as part of NI Science Festival. Established in 2014, NI Science Festival has grown to become the largest celebration of its kind on the island of Ireland and in its relatively short lifespan became one of the leading Science Festivals in the whole of Europe.
