Morrell's four voyages finally ended on 1831, with his return to New York. He then wrote his "Narrative of Four Voyages", which was published the following year. He attempted to resume his seafaring career, seeking employment with the London-based shipping firm of Enderby Brothers, but his reputation had preceded him and he was rejected. Charles Enderby stated publicly that "he had heard so much of him that he did not think fit to enter into any engagement with him." Morrell also sought to join Dumont D'Urville's expedition to the Weddell Sea in 1837, but his services were again declined. He reportedly died in 1839, and is commemorated by Morrell Island, 59°27'S, 27°19'W, an alternative name for Thule Island in the Southern Thule sub-group of the South Sandwich Islands. Robert Johnson, who coined the name New South Greenland, disappeared with his ship in 1826, while investigating the Antarctic waters in the vicinity of what would later be known as the Ross Sea.
