Richard W Humphreys served as captain of Isabella on the British Whaling and Relief Expeditions, sailing with William Lee to Lancaster Sound and Prince Regent Inlet in search of traces of John Ross's missing Northwest Passage expedition. In August 1833, Humphreys picked up Ross and his crew in Lancaster Sound. Humphreys was appointed master of HMS Cove on the British Relief Expedition (leader James Clark Ross) in 1836, sponsored by the Admiralty and private subscription to rescue the crews of eleven whaling vessels that had been beset and forced to winter in Davis Strait in 1835.
