‘The ANZAC Dive’: Australian, New Zealander Dive To Challenger Deep

Australian Tim Macdonald and New Zealander Capture McCallum this week teach a depth legend for both international locations as they was the deepest diving Australian and Kiwi ever.

The pair accomplished a preliminary depth of 10,925 meters (35,843 toes) at the backside of the Challenger Deep in the Mariana Trench southwest of Guam.

The 12-hour dive became once accomplished on this planet’s simplest submersible licensed for operations at any depth in any ocean — the DSV “Limiting Relate,” owned by Caladan Oceanic.

In step with McCallum:

“We did spare a plot for Sir Ed [Hillary] as we descended thru 8,850 meters [29, 035 feet, the equivalent height of Everest] and soundless had any other couple of kilometers to switch. It’s a extraordinarily lengthy capability down and testomony to the unattainable engineering that has gone into this automobile and to the team that relieve it.”

The dive’s well-known motive became once to study acoustic navigation equipment that might be old as an relieve to deep ocean be taught. When working at indecent depths, researchers have to depend on acoustic telemetry to navigate to clutch precisely the place samples were soundless.

MacDonald said:

“It became once a busy dive however we took the time to teach a gradual-hearted world legend; the world’s deepest ever vegemite sandwich, and Anzac biscuits; which is something simplest Australasian’s basically designate.”

The pair conducted a series of technical acoustic monitoring exercises, ran a 2000-meter (6562 foot)-lengthy high-definition digicam transect and picked up geological samples. For the length of the dive, the submersible interacted with three independent “landers” that had been positioned on the seafloor sooner than the dive and old its manipulator to catch geological samples.
