The Erebus and Terror in the Antarctic

James Clark Ross · 1839 CE – 1843 CE · Earth

Find the South Magnetic Pole and build a worldwide record of magnetic observations.

Historical context

A worldwide campaign of magnetic observation, the “magnetic crusade”, sent British, French and American ships south in the same seasons to find the southern magnetic pole. Ross had the only two ships strengthened for ice, and used them to do what his rivals thought impossible: sail straight into the pack.

The voyage, step by step

1. Erebus and Terror sail

   September 1839

   In September 1839 two bomb vessels, rebuilt for ice, leave the Thames for four years in the Southern Ocean.

2. Sixty-eight days at Kerguelen

   May 1840

   From May 1840 the ships lie at Christmas Harbour taking hourly magnetic readings through almost continuous gales.

3. Franklin’s welcome

   August 1840

   At Hobart in August 1840 the governor, Ross’s old Arctic commander John Franklin, builds him an observatory in a fortnight.

4. Into the pack

   5 January 1841

   On 5 January 1841 Ross drives his ships straight into the ice, and four days later comes out into an open sea.

5. Victoria Land

   11 January 1841

   On 11 January a range of snow mountains rises to the west; boats land on an offshore island to claim the coast.

6. A volcano in the ice

   28 January 1841

   On 28 January the ships find a smoking mountain 3,800 metres high at 77° south, and name it for the Erebus.

7. The Great Ice Barrier

   1841 CE

   East of the volcano the ships meet a vertical cliff of ice 50 metres high and follow it 450 kilometres without finding an opening.

8. Collision among the bergs

   13 March 1842

   In a gale on 13 March 1842 the two ships collide in a field of icebergs and lock together, rigging in rigging.

Outcome

Broke through the pack into a new sea, discovered Victoria Land, Mount Erebus and the Great Ice Barrier.

James Clark Ross

British polar navigator who reached the North Magnetic Pole and then broke into the Ross Sea, sighting Mount Erebus and the Great Ice Barrier.
