Abstract

The Bounty Channel system is located within the Bounty Trough, a Cretaceous rift on the eastern edge of the New Zealand microcontinent. Today, the system is fed with sediment from the eastern South Island shelf, through the Otago Fan complex. The main Bounty Channel is about 800 km long and forms a sediment transport link between the continental margin and the distal Bounty Fan, located at the mouth of the Bounty Trough and onlapping onto abyssal oceanic crust. The Bounty Channel system has existed in its present setting since the inception of the Alpine Fault plate boundary in the mid-Cenozoic, while ancestral marine channel systems occur back to the Paleocene.
