Hello Bridgeview EII,
We sent all your cups down to 6000 m (6 km or 3.7 miles) when were crossing the Kermadec Trench just to the east of New Zealand. The trench itself is much deeper. At at 32.5S, the deepest place we found was 9226 m. Unfortunately, we couldn't send our instruments down that far. We had to stop at 6000 m.
