Mark Tansey's *Coastline Measure* is a monochromatic oil painting rendered in his signature single-hue palette, depicting figures engaged in the act of measuring a rugged coastline with surveying tools. The work plays with the philosophical paradox of quantifying an inherently irregular, infinite natural boundary, drawing on concepts such as the fractal nature of coastlines famously explored in mathematics. Tansey's meticulous, illustrative technique lends the scene an air of deadpan scientific authority while quietly undermining the certainty of empirical measurement.
