Expedition Nears Nikumaroro to Test Possible Earhart Wreck Site
Researchers from the U.S.-based Archaeological Legacy Institute and Purdue University are sailing to Nikumaroro Island to inspect a lagoon-edge anomaly as possible wreckage of Amelia Earhart's aircraft, with arrival expected by Monday.
The team, led by Archaeological Legacy Institute head Richard Pettigrew, departed the capital of Kiribati on Wednesday aboard the Marin Mainiku, a Kiribati National Shipping Line vessel, for the 830-mile transit to the atoll BBC. Purdue described the transit as a six-day sea voyage Purdue. All 17 expedition members were scheduled to assemble together for the first time at Tarawa, Kiribati, on Oct. 6, with sea departure planned for Oct. 7. An Oct. 9 update placed the crew at sea with about 72 hours remaining. The vessel was tentatively expected to reach Nikumaroro around midday Monday, Oct. 12, local time.
The immediate objective is the Taraia Object, on the edge of a lagoon off Nikumaroro. The feature was first spotted in satellite imagery in 2020. Purdue said it has since been confirmed as visible in aerial photography dating back to 1938. The missing aircraft was a Lockheed Electra 10-E. If researchers confirm the object as Earhart's aircraft, the team plans to return for a full-scale archaeological excavation the following year.
Access shapes the work. Nikumaroro is part of Kiribati, a multi-island country, and is a remote South Pacific atoll — a ring of coral around a shallow lagoon — halfway between Australia and Hawaii. To reach the interior lagoon, the team must navigate a narrow gap in the atoll reef created by the British in 1963. The island was last inhabited in 1963.
The 1937 flight remains the reference point for any Nikumaroro hypothesis. Earhart vanished in 1937 while attempting to circumnavigate the globe. She arrived in Lae, Papua New Guinea, on 2 July 1937 in her Electra twin-engine plane. Earhart and navigator Fred Noonan planned to travel from Lae toward Hawaii and then back to California. The plane vanished while trying to reach Howland Island to refuel. Howland is a remote, uninhabited coral island near Nikumaroro.
Earlier results explain the caution around the new target. Ric Gillespie, who specialises in recovering historic aircraft wrecks, told Reuters the Taraia Object looked like a tree fallen from the atoll into the water. A 2024 sonar claim — sonar maps the seafloor with sound waves — of Earhart's plane lying about 4,877m (16,000ft) below the surface near Howland Island was later confirmed to be a rock formation. A 2019 expedition by the marine archaeologist who discovered the Titanic wreck to investigate possible landing gear near Nikumaroro failed to find anything. The current search was originally announced in July 2025, 88 years to the day after Earhart and Noonan disappeared.
The broader context here is why a single lagoon image can still prompt a university-backed voyage after so many false leads. Nikumaroro offers a narrow, checkable test. A fixed object with a photographic record extending to 1938 can be approached, measured, and either ruled in or ruled out in a way that deep-ocean sonar contacts often cannot.
In my view, that verifiability is also the risk. Shallow lagoon environments rework debris, coral and fallen vegetation. Visual similarity from orbit does not resolve material, structure or provenance.
Looking at what this means for the next phase, the expedition design acknowledges that limit. This voyage is inspection, not recovery. Confirmation would trigger a separate, full-scale archaeological excavation next year, with all the permitting, conservation and jurisdictional questions that work inside Kiribati waters would entail. A negative finding would still narrow the field by closing one of the few targets with a decades-long image trail.
