Deep Repository is an attempt to design a solution for a final resting place for digital media. An archive for the post-apocalyptic. The concrete module may contain master formats (eg dv tapes, hard drives) securely insulated and encased, whilst associated documents other formats are stored on a read only SD card, accessible via the waterproof usb adaptor. The work was developed as part of a residency at Florence Mine, Egremont. The title is a reference to a proposed method of storing nuclear waste at nearby Sellafield in Cumbria.
