Porcupine Bank Canyon

The Porcupine Bank Canyon (PBC), in Irish waters 370 km SW of Mizzen Head, is disconnected from terrigenous influences being isolated  from rivers and across shelf sediment/ water mass influences. Unlike all other European submarine canyons, the PBC and its smaller neighbours, represent a natural laboratory for studying oceanographic changes unimpaired by changes in terrestrial (human dominated) environment.

Significant deep-sea exploration and surveying has established baseline data revealing a major carbonate-dominated upper canyon system (RTÉ 9 O’clock News, 16th July 2015) hosting extensive heterogeneous cold-water habitat cover.
