Walk into the North Wall Arts Centre and you are immersed in blue light. This exhibition, pieced together by hand from multiple triangles of dyed and lacquered tissue paper, has been created for this gallery by Gabby O’Connor, an Australian who now lives in Wellington, New Zealand.

Gabby has fashioned a breathtaking room-scale iceberg form. It falls from the ceiling and represents the bulk of an iceberg, which is usually hidden underwater and out of sight. The installation depicts the icebergs that will eventually split from the Ross Ice Shelf, carrying the frozen remains of Captain Scott and his companions on the Polar expedition who died near the South Pole in 1912.

In creating this work, Gabby imagines the homecoming of the lost explorers encased in icebergs that could navigate their way back to the UK, moving northwards together.

Because the work has been designed to complement the space in which it hangs, the pieces dominate the gallery, such that the visitor enters a space richly suffused with blue light. While you can walk round the gallery, gazing up as you go, it is tempting to sit on the floor and look up to examine the blue forms suspended above you.

Gabby has not travelled to Antarctica yet, though obviously she plans to do so and see real icebergs for herself. Until that happens she is content to call on the many practical skills she has acquired over the years to capture the shrinking forms of icebergs as she imagines them. She hopes that her work will act as a stark reminder of the effects of global warming.

This is one of the most stunning exhibitions the North Wall gallery has staged. I strongly recommend a visit, perhaps several. I have certainly seen nothing like it.
