Marie Tharp and Bruce Heezen’s pioneering research had shown that the ocean basins were not featureless depths but structured terrain, crossed by ridges, trenches and fracture zones—evidence that helped overturn fixed-continent geology and establish plate tectonics. This 1971 National Geographic supplement is a later popular presentation rather than one of their groundbreaking 1950s maps. Its distinction lies in Heinrich Berann’s painterly interpretation: illuminated slopes, sculptural ridges and deep-shadowed basins give scientific bathymetry the immediacy of an aerial view. The Arctic basin appears encircled by North America, Greenland, Europe and Asia, its submarine geography made unexpectedly dramatic and legible. An annotated conventional map of the Arctic Ocean is printed on the reverse.\u003c\/em\u003e\u003c\/p\u003e","brand":"Antiquemapsandprints.com","offers":[{"title":"Default Title","offer_id":53896240562523,"sku":"P-6-112330","price":45.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/9583\/1643\/files\/P-6-112330a.jpg?v=1787843769","url":"https:\/\/www.antiquemapsandprints.com\/products\/arctic-ocean-floor-tharp-heezen-berann-bathymetric-physiographic-map-1971-p-6-112330","provider":"Antiquemapsandprints.com","version":"1.0","type":"link"}
