George Francis Lyon was an English naval officer and explorer of Africa and the Arctic. While not having a particularly distinguished career, he is remembered for the entertaining journals he kept and for the pencil drawings he completed in the Arctic; this information was useful to later expeditions.

HMS Hecla was a Royal Navy Hecla-class bomb vessel launched in 1815. Like many other bomb vessels, she was named for a volcano, in this case Hekla in southern Iceland. She served at the Bombardment of Algiers in 1816. Subsequently, she took part in three expeditions to the Arctic. She then served as a survey vessel on the coast of West Africa until she was sold in 1831. She became a merchantman and in 1834 a Greenland whaler. She was wrecked in 1840.
