The ships anchored in Recherche Bay on 22 January, and the expedition spent a period of five weeks in that area, watering the ships, refreshing the crews, and carrying out explorations into both natural history and geography. Beautemps-Beaupré, in company with other officers, surveyed the northern extensions to Storm Bay – the western extension was found to be a mouth of a river which received the name Rivière du Nord – it was renamed the Derwent River a few months later by the next visitor to this area, Captain John Hayes in "Duke of Clarence" and "Duchess".
