Researchers on Nikumaroro have five days to say whether a lagoon shape is Earhart's plane or a tree
Purdue and Archaeological Legacy Institute researchers reached Nikumaroro on Monday for a five-day inspection of the Taraia Object. Seen in 2020 satellite imagery at a lagoon edge, it is read by some as Earhart's plane and by others as a collapsed tree.

Key figures: Purdue says this is the first authorised trip to Nikumaroro in 7 years; the Taraia Object is believed to lie 10 feet from shore in as little as five feet of water; expedition leader Rick Pettigrew says Earhart and Noonan disappeared more than 89 years ago.

| First authorised trip to the island in, per Purdue | 7 years | 5 | |
| Taraia Object's believed distance from shore | 10 feet | in as little as five feet of water | 9 |
| Since Earhart and Noonan disappeared, more than | 89 years | expedition leader Rick Pettigrew said | 6 |
What happened
- On Tuesday the crew plans to take the ship through a narrow gap the British blasted in the atoll's reef in 1963, to prepare for landing.
- On Wednesday the work shifts to the Taraia Peninsula, where researchers will search for evidence, including magnetic metals.
- Researchers say weather and ocean conditions will continue to be a factor, and El Niño could limit daily access to shore.
- Coconut crabs hunt at night, so the crew will sleep aboard the ship for their own safety.
Why it matters
- cost Access is scarce: Purdue calls this the first authorised trip to the island in seven years, so a day lost to weather is unlikely to be recovered on a quick return.
- constraint Dredging comes last in the schedule, so delays push against the one step that examines the object itself.
- exposure Because the crew sleeps aboard, every shore session depends on passing the reef channels, and channel safety sets the pace of the work.
The two searches ask different questions. The peninsula sweep for evidence, including magnetic metals, covers ground [8]. The dredging goes to the object itself, which is believed to sit 10 feet from shore in as little as five feet of water, depending on the tides [9]. We think the dredging is the step that can discriminate. A collapsed tree and an airframe should look different once sediment is moved aside, and shallow water puts the object within reach of dredging equipment. A clean metal sweep ashore would leave the object itself uninspected.
Expedition leader Rick Pettigrew said in a blog post on Monday: "It is incredibly rewarding to be this close to completing our inspection of the Taraia Object and potentially solving, at long last, the outstanding mystery of the disappearance of Amelia Earhart and Fred Noonan more than 89 years ago" [6]. His sentence hedges the payoff with the word "potentially".
Earhart flew an Electra twin-engine plane, and it vanished in 1937 as she and Noonan tried to reach Howland Island, near Nikumaroro, to refuel [12]. An aircraft-shaped metal object in a lagoon would still have to be tied to that aircraft. The BBC's account does not describe how the team plans to do that.
The weather risk is local. The BBC describes the El Nino now under way as the strongest ever recorded [3]. Michael Krivor, a marine archaeologist on the trip, said he is concerned about a weather pattern traveling from east to west that could interfere with "safe transit in and out of the blasted channels" [11].
Several theories hold that Earhart survived a crash on the island and was overcome by giant crabs that carried away her bones [13]. In 2018 the International Group of Historical Aircraft Recovery used pig carcasses to show that the crabs could haul bodies into their burrows and pick the bones clean in under two weeks [14]. A plane-or-tree answer from Taraia would not settle whether Earhart's remains were ever on the island.
What to watch
- What the dredging shows once sediment is moved: wood, or a metal structure with aircraft features.
- Whether El Niño weather cuts shore access enough to squeeze the final dredging step.
- Any published method for matching a metal find to Earhart's Electra.

Coconut crabs emerge at night to hunt small mammals and seabirds, and will force the search crew to spend nights on their ship for their own safety.

This is the first authorised trip to Nikumaroro Island in seven years, and the first visit to the Taraia Peninsula in more than 15, according to Purdue.

On Tuesday the crew plans to navigate through a narrow gap "blasted" in the atoll's reef by the British in 1963 to prepare for landing.

Lastly, the researchers will use dredging equipment to move sediment for a visual inspection of the mystery object, which is believed to be located only 10 feet from the shore in as little as five feet of water, depending on the tides.

Earhart flew an Electra twin-engine plane; the plane vanished without a trace in 1937 as she and Noonan tried to reach uninhabited Howland Island, near Nikumaroro, to refuel.

Several theories suggest Earhart survived a crash on the island before being overcome by giant meat-eating crabs that carried away her bones.

In 2018, the International Group of Historical Aircraft Recovery used pig carcasses to demonstrate how the crabs were able to drag bodies to their burrows and strip the bones of flesh in less than two weeks.

In the published schedule, the dredging and visual inspection of the object itself comes after the Tuesday channel transit and the Wednesday peninsula search.

The Taraia Object was first spotted sitting on the edge of a lagoon off Nikumaroro in satellite imagery in 2020.

Some believe the Taraia Object to be the wreckage of Earhart's plane, but others have expressed scepticism that it is an aircraft at all, with one theory suggesting it is a collapsed tree.
