Survey teams map a defined search area with complementary instruments—usually side-scan sonar, multibeam sonar and magnetometers, with sub-bottom profiling when burial is possible. Divers or remotely operated vehicles (ROVs) inspect promising anomalies. Once a target is confirmed, its position, condition, debris field and relationship to the surrounding seabed are documented in place with measurements, photographs, video and mapped observations. Overlapping images can then be processed into a photomosaic or 3D model.
This is not a single-instrument treasure hunt. A sonar mark or magnetic reading is only a candidate until it has been interpreted, positioned and inspected. In many cases the debris field is as informative as an intact fuselage.

What an underwater aircraft-wreck search is trying to establish
A search normally has two linked objectives: locate a physical anomaly in a defined area and determine whether that anomaly represents aircraft material. The result may be an intact airframe, a crashed aircraft broken into a spread of parts, or isolated debris. “Wreck” should therefore be used carefully; the evidence may support only a debris field until visual inspection and analysis are complete.
Historical research can narrow the area, but sensors supply the seabed evidence. Navigation data ties every reading to a position, allowing a team to compare anomalies with the reported flight path, depth, terrain and other records. The position, shape and distribution of objects can reveal more than a single recognizable component.

1. Define the objective, area and operating plan
Set a specific survey question
Before equipment is selected, the team decides what it needs to learn. A broad reconnaissance survey may seek any man-made object in a large area. A follow-up project may map one suspected crash site, locate buried components or document a known aircraft without disturbing it. Coverage, resolution, sensor choice and the amount of visual inspection all depend on that objective.
Match the design to the environment
Depth, seabed type, water conditions, relief, expected target size and the possibility of burial affect the design. The U.S. Navy’s fieldwork guidance describes choosing among side-scan sonar, magnetometry or gradiometry, multibeam sonar, sub-bottom profiling, autonomous underwater vehicles (AUVs) and ROVs, or combining several resources. NOAA mapping guidance likewise emphasizes system configuration, calibration, coverage, positioning, target detection, quality control, uncertainty and processing.
Resolve permissions before fieldwork
Archaeological guidance from UNESCO’s Annex to the 2001 Convention addresses project design, qualifications, documentation, conservation and site management. The permissions, ownership rules and protection requirements for a particular aircraft wreck depend on its jurisdiction and circumstances. A general method for locating a wreck is not permission to excavate, recover or move it.

2. Search the seabed with complementary sensors
No sensor performs every job. The instruments below answer different questions and produce different kinds of evidence.
| Instrument | Primary information | Strengths | Important limits |
|---|---|---|---|
| Side-scan sonar | Acoustic imagery of seabed texture, objects and shadows | Efficiently images broad areas; relief and acoustic shadows can make objects stand out | Does not measure depth or provide bathymetry; a mark is not an identification |
| Multibeam sonar | Bathymetry and seabed shape | Maps terrain, depth and site-specific features that complement sonar imagery | Its value depends on positioning, calibration, coverage and processing quality |
| Magnetometer or gradiometer | Variations in Earth’s magnetic field | Can indicate ferrous aircraft material whether exposed or buried | Geological magnetic variation and other sources can create anomalies; interpretation and follow-up are required |
| Sub-bottom profiler | Features beneath the seabed | Investigates potentially buried wreckage or debris | Not a substitute for surface imagery or visual confirmation |
| AUV or ROV | Vehicle-based sensing and inspection | ROVs can investigate deep or hazardous sites; vehicles can carry sensors close to the target | Operations, navigation and observations must still be documented and quality-controlled |
Side-scan sonar: broad acoustic imagery
Side-scan sonar sends acoustic pulses across the seabed and records returning echoes. Differences in return strength create an image in which objects, seabed texture and acoustic shadows may be visible. A shadow can indicate relief above the bottom, but the image is not a depth survey. NOAA explains that side-scan sonar is commonly paired with single-beam or multibeam sonar when depth information is needed.

NOAA’s overview gives example frequency bands rather than universal specifications: lower-frequency systems around 50–100 kHz can cover broader areas at lower resolution, while higher-frequency systems around 500 kHz–1 MHz cover narrower swaths with more detail. The appropriate setting depends on the system, altitude, target and survey objective.
Multibeam sonar: depth and seabed form
Multibeam sonar collects bathymetric information across a swath. A resulting terrain model can show slopes, channels, scour and other seabed shapes that help interpret a side-scan image and plan an inspection. It also supplies a depth framework for measurements made during later ROV or diver work.
Magnetometry: finding ferrous material
A magnetometer measures changes in the surrounding magnetic field. Ferrous aircraft components can produce an anomaly even when they are partly or wholly buried, which makes magnetometry complementary to sonar. NOAA’s explainer describes a general sampling example of about one reading per second (1 Hz), published by NOAA Ocean Exploration in 2020 and updated in 2021; the rate can be changed and is not a universal setting for every instrument or survey.
Magnetic data can also reflect geological sources or other metal on the seabed. Teams therefore map anomalies with their positions, compare them with sonar and terrain data, and inspect selected targets rather than treating every peak as an aircraft.
Sub-bottom profiling: looking below the surface
When aircraft parts may have settled into sediment, sub-bottom profiling provides a distinct line of evidence by investigating layers beneath the seabed. It is used alongside, not instead of, surface-imaging and magnetic methods. The resulting interpretation should identify uncertainty and distinguish a possible buried object from natural sediment structures.

3. Position, process and interpret the survey data
A sensor reading has limited value without a reliable position. Navigation records connect each sonar ping or magnetic sample to a map location, while calibration and quality-control checks help reveal gaps, noise and uncertainty. Teams process the data into mosaics, bathymetric surfaces or anomaly maps, then rank targets for inspection.
Interpretation considers the shape, dimensions, acoustic shadow, magnetic response, depth and local geology together. An isolated, neatly shaped return may deserve inspection, but it does not establish aircraft identity. A cluster of anomalies that aligns with a debris trail can be more informative than one large mark. The surrounding area should be surveyed far enough to characterize that relationship.
4. Investigate candidate anomalies safely
Use divers when conditions permit
Divers can inspect accessible targets, photograph components and take measurements. Their observations should be tied to mapped positions and recorded with enough detail for another researcher to understand what was seen, where it was found and how it relates to nearby debris.
Use an ROV for depth or hazards
ROVs are useful at deep-water, confined or otherwise hazardous sites because the vehicle can carry cameras, lights and instruments without placing a diver in the same environment. Navy guidance describes using ROVs to investigate anomalies and recording observations for each target. For an aircraft, initial ROV assessment can include positions at the wing extremities, along with the fuselage, engines, landing gear and other diagnostic parts where visible.
Separate confirmation from identification
Visual inspection confirms that an anomaly is material on the seabed; establishing the aircraft’s identity may require markings, configuration, historical records and the pattern of the debris field. A high-resolution sonar image alone should not be presented as proof of identity.

NOAA’s Ocean Fact page illustrates the discovery role of sonar with a high-resolution side-scan image of a Second World War B-25 found in Papua New Guinea in 2017. The example demonstrates how sonar can reveal a target; it does not establish that sonar alone confirmed the aircraft.

Record the site, not just a recognizable object
In-situ documentation preserves the spatial context that recovery can destroy. NOAA states that “Maritime archaeologists now prefer to document underwater sites in situ, or in place, right where they are found on the seabed.” A complete record can include:
- Mapped position fixes and depth for the site and significant components.
- Photographs and video showing condition, orientation and relationships among parts.
- Measurements, sketches and written observations tied to locations.
- The limits and density of the debris field, including surrounding seabed features.
- Environmental and operational notes needed to interpret image quality and uncertainty.
The Navy guidance calls for clear, accurate records of field operations and observations and recommends investigating surrounding areas to characterize the debris field and immediate environment. Recording only the cockpit or one engine leaves out evidence about how the aircraft came to rest.
Build a photomosaic or 3D model
Photogrammetry uses overlapping photographs to reconstruct a photomosaic or three-dimensional model. It can document a site quickly and help cover areas that are difficult to reach repeatedly. Useful acquisition practices include adequate image overlap, consistent lighting where possible, scale bars and position fixes. Exact camera spacing, overlap and lighting are project decisions: visibility, depth, camera system, relief and the purpose of the model all change the appropriate settings.

The model should retain its scale information and explain how photographs were positioned and processed. A visually impressive 3D reconstruction without control points, scale or uncertainty is difficult to measure or compare with later surveys.
6. Preserve the archaeological record
Documentation is part of conservation. UNESCO’s Annex to the 2001 Convention places project design, qualifications, excavation documentation, conservation and site management within the same framework. In practical terms, teams should plan who is qualified to operate each system, how records will be stored, how the site will be revisited and what intervention—if any—is justified.
Leaving a wreck in place can preserve the arrangement of parts, sediment relationships and associated objects. If intervention is proposed, it should be separately authorized, documented and supported by conservation planning. A location map, raw survey data, processed products, field notes and photographs together form a more durable record than any single image.
A practical end-to-end workflow
- Define the question and boundary. State whether the aim is reconnaissance, confirmation, mapping of a known site or investigation of buried material.
- Compile historical and geographic information. Use it to set a search area, while treating reported positions as uncertain until tested.
- Select complementary sensors. Pair side-scan imagery with multibeam depth data when terrain matters, magnetometry when ferrous material or burial is possible, and sub-bottom profiling for subsurface targets.
- Plan navigation, calibration and coverage. Establish how readings will be positioned, checked and processed before collection begins.
- Map and rank anomalies. Compare acoustic, bathymetric and magnetic evidence and record uncertainty rather than assigning automatic identities.
- Inspect priority targets. Use divers where safe and suitable; use an ROV for deep or hazardous locations.
- Expand around confirmed material. Map the debris field and immediate environment, including component positions and seabed context.
- Create the permanent record. Combine coordinates, measurements, notes, photographs, video and, where appropriate, a scaled photomosaic or 3D model.
Common mistakes and how to avoid them
- Calling a sonar mark a wreck. Treat it as a candidate anomaly until inspected and assessed.
- Using side-scan sonar as a depth instrument. Add multibeam or another bathymetric method when elevation and seabed shape are required.
- Assuming a magnetic peak is aircraft material. Check geological variation and compare the anomaly with sonar, terrain and visual evidence.
- Searching only where an intact fuselage is expected. Survey beyond the first object to find scattered components and define the debris field.
- Collecting photographs without scale or position. Add scale bars, control or position fixes and notes about lighting and visibility.
- Applying fixed acquisition settings everywhere. Adapt frequency, altitude, overlap and lighting to the target, depth, relief and equipment.
- Confusing documentation with recovery permission. Confirm the wreck’s jurisdiction and required permissions before disturbing the site.
What the published methods do not establish
There is no general discovery-rate, cost or time-to-discovery statistic that can be applied to underwater aircraft searches. Outcomes vary with search-area size, depth, seabed conditions, target state, sensor configuration, weather and access. Specialist systems such as side-scan sonar, multibeam, magnetometers, sub-bottom profilers, AUVs and ROVs are professional survey equipment; consumer metal detectors, recreational sonar and ordinary cameras are not honest substitutes for an archaeological survey.
