'Pacific Ocean Floor'
An extraordinary portrait of the Pacific, revealing a submarine architecture of trenches, ridges, seamounts and abyssal plains. Marie Tharp and Bruce Heezen’s cartography transformed understanding of the ocean floor during the 1950s. By tracing mid-ocean ridges and their central rift valleys, their work supplied crucial visual evidence for seafloor spreading, continental drift and the emerging theory of plate tectonics. National Geographic issued this map in 1969: it is a later popular synthesis, not one of the original groundbreaking charts. Its appeal lies in Heinrich Berann’s artistry. Through luminous colour and sculptural shaded relief, he turns bathymetric data into a convincing landscape, from the East Pacific Rise to the Mariana and Peru–Chile trenches. A conventional annotated map of the Pacific Ocean is printed on the reverse.
