Goggle Earth Goes underwater
This week amid a flurry of media coverage Goggle Earth issues an update, which allows viewers to navigate the deep-sea bed.
My own attempts - clumsy no doubt - to use this facility afford the exhilarating experience - and it is strangely physical - of crashing down towards and through the sea’s surface into an environment which is strangely reminiscent of some of the undersea scapes I have been producing using the Erdas modelling software
What is strikes me most forcibly is level of visibility it assumes. In parallel I am editing some video footage shot at a depth of between 2,500 to 3,000 metres which makes evident the difficulty of seeing anything beyond that which might be illuminated by the beam of a Remotely Operated Vehicle (ROV) (an area of approx 9-16 sq metres). No horizon is visible confounding immediately one of the primary pictorial conventions of landscape. The other surprise perhaps is the constant stream of snow like debris that falls through the water to rest on the bottom and which as soon as it is touched swirls up dramatically, obscuring the view. For me this powerfully evokes the depth involved while for the scientists I am working with it is a source of extreme frustration .
I remember when I was producing work in response to the site of a wrecked boat at Prawle Point in Devon, putting the camera (see Above and Below this page) in waterproof a housing and allowing the tide to animate the camera as a means to embed within the work a trace of the circumstances in which it was made. By the same token this dark, awkward, footage excites me because of the echo it offers of the physical the space of the deep sea bed and the resitance it offers to the attemtp of the camera to reveal it.
Sitting in the video archive at National Oceanography Centre watching this footage I am awed by the hours and hours of tape held there, all of which must be painstakingly logged. I read the entries which record sightings of a purple anemone, small sponge, vase bug etc In this world, which is so vast and lacking in familiar landmarks a mussel shell serves as an provides an important point of orientation
Returning to Goggle Underwater I find myself thinking about the virtual world it conjures and the ways in which this in turn shapes our perception of the actual world. I can’t help feeling that despite the wealth of data on which it draws, Goggle Underwater represents a making of the world in our image, which is as much scenic as it is scientific.
