An account of artistic research addressing the extra visual and extra geographic circumstances of the submaritime conducted at the National Oceanographic Centre, Southampton, 2007 – 10. During 2008–10, I was the Artist in Residence of the Leverhulme Trust, at the National Oceanography Centre, (NOCS), Southampton, working with sonar geophysicist Dr Tim Le Bas, exploring methods of seabed mapping and undersea survey. During this period I documented aspects of oceanographic study, learnt processes used by my scientific colleagues, conducted performative interventions and made works in direct response to the context of (NOCS). The work produced was shown at an exhibition at University of Wales Institute, Cardiff in 2009 and will be developed into a larger exhibition at the John Hansard Gallery, Southampton in 2012. This article constitutes both a re-presentation of my primary research and a reflection on the methods I adopted to address the issues raised by my inquiries. Works produced are both referred to directly and represented via supplementary documentation.
