On 6 January 1843 Captain James Clark Ross discovered a broad embayment east of the sound, which he named Sidney Herbert Bay after the Hon.

The broad northeast part of the sound was named Admiralty Inlet by the British expedition under James Clark Ross, who discovered it on 6 January 1843.

The UK-APC name arose from the excellent sledging conditions experienced during the Falkland Islands Dependencies Survey (FIDS) resurveying of the area of 1952, which gave to the work a picnic-like atmosphere.

Discovered by a British expedition under James Clark Ross, 1839-43, who named it for Admiral George Cockburn, Royal Navy, then Senior Naval Lord of the Admiralty.
