Bounty Trough, Submarine trough in South Pacific Ocean, New Zealand
The Bounty Trough extends 800 kilometers eastward from South Island's coast, reaching depths between 2000 and 3000 meters below sea level.
Scientists discovered nine underwater canyons within the trough during a mapping expedition by the research vessel RV Tangaroa in July 2012.
The trough received its name from the nearby Bounty Islands, which were named after the HMS Bounty vessel in the 18th century.
Research expeditions in the Bounty Trough employ specialized deep-sea equipment to study marine ecosystems at depths approaching 5000 meters.
The trough contains distinctive pock marks measuring 20 meters deep and 200 meters wide, potentially indicating methane seepage along its margins.
