John Balleny

John Balleny was the English captain of the sealing schooner , who led an exploration cruise for the English whaling firm Samuel Enderby & Sons to the Antarctic in 1838–1839. During the expedition of 1838–1839, Balleny, sailing in company with Thomas Freeman and , sailed into the Southern Ocean along a corridor of longitude centering on the line of 175°E., south of New Zealand.

Biography Balleny was born approximately 1770, and by 1798 was living in St George in the East, then the shipping quarter of London, and was part owner of a 569 ton ship, Blenheim. He was recorded as ship's master for a few trading ships up until 1824, including the trading ship Lord Cathcart and the 269-ton brig Peace. In 1824, he owned part of a whaling barque, Caledonia, but was not longer registered as the master of any ship for the following year, possibly indicating his retirement.

Voyage of Eliza Scott Samuel Enderby & Sons had sent two unsuccessful expeditions towards Antarctica in the early 1830s, and had decided to send a third - the 156–ton (bm), schooner and the 54-ton cutter . Although the ships set off from London on 12 July 1838 with Thomas Freeman in command of Eliza Scott, by the time they had reached Deal, Kent two days later, Balleny was in command and Freeman was master of Sabrina,

The Balleny squadron logged a partial break in the pack ice surrounding the southern continent, discovered the Balleny Islands in 1839, and caught a brief sight of Antarctica itself at . This patch of icy land is today called the Sabrina Coast.

Eliza Scott arrived back in England on 19 September 1839. The voyage was not profitable as the 178 seal skins that Balleny returned with did not cover the cost of the expedition.

She left on another whaling voyage on 8 July 1840. She then sailed between London and Saint Helena.
