Sea change: a tidal journey around Britain - interactive

Since 2003 photographer Michael Marten has travelled around the British coast to photograph identical views at high and low tide, six or 18 hours apart. See how the seascapes in his photographs are dramatically transformed by clicking on the vertical slider in the middle of the image and moving it left or right.



An exhibition of Michael Marten's photographs from Sea Change is at gallery@oxo, Oxo Tower Wharf, London until 30 September
