From 1839 to 1845 the survey of the north-western coasts was continued with the Beagle, first under the command of Captain Wickham, and subsequently of Lieutenant Stokes. Soon after arriving from England, in the close of 1837, the coast was examined from Roebuck Bay to King's Sound, during which cruise the Fitzroy River was discovered and navigated for 90 miles from its entrance.

Whilst examining Clarence Strait they made the important discovery of the Adelaide River, which was subsequently described by Mr. J. M'Douall Stuart as one of the best possible situations for a new settlement. Port Darwin was also discovered during this voyage.
