Challenger Deep ANZAC Expedition
A series of dives to Challenger Deep including, hopefully, the first Australian and first New Zealander


EXPEDITION: COMPLETE
FEBRUARY – MARCH 2021
The Limiting Factor returns to the Challenger Deep with a series of dives. Two Americans were firs to descend, followed by the first Australian and New Zealander. We are referring to the latter dive as the first “ANZAC Dive” to the bottom of the ocean.
All the dives were focused on continuing to map the Challenger Deep and to recover larger rock samples which has proven very challenging, historically.
We also took the first citizen of the Federated States of Micronesia, whose territory encompasses the Challenger Deep.
