Alone, months of sailing separating them from home, in the polar winter where the sun never rises, the two ships of Captain William Parry's expedition lay encased in ice from November 1819 to March 1820. In order to fully chart the North-West Passage between the Atlantic and the Pacific, it was necessary to overwinter in the Arctic, something that no other British expedition had done before. To boost morale in these uncomfortable circumstances, Captain Edward Sabine (1788 1883), a senior scientist carrying out measurements of natural phenomena, founded and edited a weekly magazine, which ran...

The explorer, soldier and geophysicist Sir Edward Sabine (1788 1883) served as astronomer on John Ross's 1818 expedition in search of the North-West Passage. His return to the Arctic, under William Parry in 1819 20, compounded a keen interest in geomagnetism and his publications earned him the Copley Medal of the Royal Society (whose presidency he would later hold). His experience and expertise made him a natural editor, therefore, of this Arctic narrative, translated into English from German by his wife, Elizabeth Juliana Leeves (1807 79), and published in 1840. It is the account by...

As early as the seventeenth century, scientists realised that a pendulum swings more slowly at the equator than it would at the North Pole. Newton predicted that gravity increased with latitude, and that the Earth could not be perfectly spherical. Although various experiments were undertaken to determine the exact degree of this ellipticity, none proved successful until physicist Edward Sabine (1788 1883) embarked on a series of expeditions across the world. Based on pendulum measurements from a wide range of latitudes, from Jamaica to Spitsbergen, his results were very different to...
