Present-day Canada and the Arctic territories of
Greenland are separated by a vast expanse of sea which is ice-bound
for the greater part of each year. So what could possibly have
enticed navigators to a place so hostile from the 16th century
onwards?
The answer? A passage through the Pacific Ocean and the west
coast of North America, which would open up trade routes that ship
owners could but dream of. William Baffin began exploring the
region in 1616 and gave his name to the enormous bay that stretches
from the Labrador Sea in the east to the islands of Devon and
Ellesmere in the west.
Two centuries later, in 1818, Captain John Ross was awarded the
command of a new expedition to explore the bay and attempt to
discover this famous Northwest Passage. He left London on 25 April
1818 with two ships; the Isabella, which he commanded, and the
Alexander, which was entrusted to young lieutenant William Edward
Parry.
After four months spent following in the wake of William Baffin,
the expedition reached longitude 81° west on 31 August 1818. There,
Captain Ross was misled by a mirage, which appeared to be a remote
mountain range to the west. He named it the Crocker Mountains and
assumed it to be a natural barrier to any northwest passage. The
next day, despite the protests of several of his officers, he
decided to return to London. Parry fulminated: "Attempts were
relinquished just at a time when there was the greatest chance of
succeeding!"
It goes without saying that Ross carried marine chronometers on
board. Despite the gales and extreme conditions, two of these, made
by Arnold, worked perfectly: Arnold's chronometer No. 369 advanced
by just five seconds and five-tenths of a second each day, and, as
Captain Ross noted in his logbook:
"Arnold's No. 25, when compared with Earnshaw's two
chronometers, and the means of the rest, and also with the result
of lunar observations, was found to have preserved a steady rate of
4'' per day."
In 1819, Parry was entrusted with the responsibility of leading
a second expedition to Baffin Bay. He returned with two ships, the
HMS Griper and HMS Hecla. After over a year's exploration, he
reached longitude 111°46' west, then the farthest western point
reached by man, in June 1820. This lay to the west of Melville
Island, proving that John Ross had been mistaken. It also
established that the western horizon was comprised of a string of
islands and that the famous Northwest Passage certainly existed. He
was promoted to the rank of commander upon his return.
Both the Griper and the Hecla were equipped with marine
chronometers made by Arnold, six in all, two of which featured an
eight-day reserve indicator complication, and a pocket chronometer,
No. 2109. This last found favour with Parry. Here is what he
recorded in his logbook on 2 June 1820:
"These and the rest of our observations for latitude and
longitude, obtained during this journey, were made with a sextant
and artificial horizon, and the longitudes are by the chronometer,
No. 2109 of Arnold, which I carried in my pocket."
Commander Parry was an indefatigable explorer. He attempted to
cross the Northwest Passage twice more, in 1821 and 1824, and
reached latitude 82°45' north for the first time in 1827, during an
expedition to the North Pole. This record stood for almost five
decades. It would be 1906 before Norwegian explorer Roald Amundsen
completed the traverse from one ocean to the other, and the North
Pole was not reached until 1908 by Frederick Albert Cook and in
1909 by Captain Robert Peary.
