An iceberg scour is a long groove or depression left when a grounded iceberg keel moves across the seabed. To distinguish one from another seafloor disturbance, assess its shape, margins, endpoints, spatial pattern and relationship to nearby landforms together. No single groove shape or size proves iceberg origin.
What an iceberg scour looks like
Iceberg scours—also called iceberg ploughmarks—are elongated incisions made as an iceberg keel grounds and travels over seabed sediment. On a bathymetric map, a track may appear straight, curved or slightly sinuous. It may cross other tracks, leaving a pattern that can help establish which feature formed later.

Examine the groove and its surroundings rather than treating the trough as a stand-alone clue. A flat-bottomed incision can be consistent with a scour; finer ridges and grooves may be preserved in fresher examples. Preservation changes over time and as the seabed is reworked.

Clues that strengthen an iceberg-scour interpretation
- Lateral berms or push-up ridges: Raised sediment beside the trough supports an interpretation of keel ploughing.
- A terminal grounding pit: A pit at the end of a groove can indicate where a keel grounded or stopped. Its presence strengthens the interpretation, but it is not required.
- Paired parallel tracks: Some scours occur as pairs, plausibly made by a double-keeled iceberg. This is occasional evidence, not a defining feature.
- Relatively isolated distribution: Scours may be distributed irregularly and often do not connect to regional features such as canyons or gullies. Compare the candidate with the larger landform pattern.
- Cross-cutting tracks: Where one groove cuts across another, the crossing can indicate relative order. A smoother, more degraded appearance may also be consistent with greater age, but does not establish an absolute date.
A 2012 study of Rockall Bank described the combination of grounding pits, irregular distribution, lateral berms, push-up ridges, occasional paired tracks and a lack of connection to canyons or gullies as evidence for iceberg scouring. These are clues to weigh together, not a universal set of uniquely diagnostic tests for every seabed.

How to compare a groove with other disturbances
Start with the candidate’s continuity and planform, then check whether its margins and endpoints fit the interpretation. An isolated, curving groove with adjacent ridges, a terminal pit or a parallel track is more consistent with iceberg-keel interaction than a groove that follows or connects to a larger canyon or gully. A clear relationship to regional drainage should prompt other explanations.
Other glacial landforms can occur in the same area. Mega-scale glacial lineations and grounding-zone wedges are distinct landform classes; assess them by their own geometry and setting rather than labeling every glacial-looking feature a scour. Tidal ridges and sediment deformation can also complicate interpretation, so consider local stratigraphy and neighboring landforms.

The literature summarized here does not provide a complete checklist for every natural or human-made seabed disturbance. Where several explanations remain plausible, compare planform, continuity, ridges and pits, regional connections, cross-cutting relationships, substrate and shallow stratigraphy, and the quality of the survey. Treat the result as a geomorphic interpretation supported by converging clues—not as certainty from one feature.

Use survey data that can resolve the feature
Multibeam bathymetry
Multibeam echo sounders map seabed depth across a swath, giving a broader view of relief than a single depth trace along a ship’s track. Inspect both shaded relief and the underlying bathymetric grid at a resolution suited to the feature. Higher-resolution mapping may reveal subtle landforms, but swath-edge artifacts can also become more apparent.

Side-scan sonar and sub-bottom profiles
Side-scan sonar adds an acoustic view of seabed texture and relief that complements bathymetry. A sub-bottom profiler can help show how a feature is expressed beneath the surface and distinguish surface morphology from shallow subsurface structure.
Combine datasets and check data quality
Some AUV surveys have combined multibeam echo sounding, side-scan sonar, sub-bottom profiling and high-resolution synthetic aperture sonar. One Antarctic Peninsula study reported imaging some glacial landforms at horizontal resolutions of a few tens of centimetres; that capability applies to its survey system and should not be assumed for other datasets.

Visibility depends on more than instrument type. Resolution, grid choice, sound-velocity correction, survey coverage, sediment type and preservation all affect whether subtle relief can be recognized. If a feature is missing from a coarse or incomplete survey, it may simply be unresolved.
Why size is not a diagnostic cutoff
Reported dimensions differ by site and study, so use them as examples rather than universal thresholds.
| Reported measurement | Study context | How to interpret it |
|---|---|---|
| Average depth of 1–2 m and width of about 30–40 m | Continental Shelf Research authors, 1991; Labrador continental shelf | Regional averages, not limits for all scours. |
| Typical width from tens of metres to 100 m and depth of 1–10 m | Geomorphology authors, 2012; Rockall Bank | The article also describes much larger or deeper local examples. |
| Keel depth up to 500 m and incisions up to 15 m deep | Geomorphology authors, 2012; isolated Rockall Bank marks, inferred under the study’s stated full-glacial sea-level assumption | A regional interpretation, not a general size range for iceberg scours. |
A 2021 study in the northeastern Baltic Sea, west of Estonia, interpreted two scour populations and proposed a likely formation interval of 13,800–12,300 years BP for that study area. Those dates are a regional interpretation, not a general age for iceberg scours.
What the tracks can—and cannot—say about age
Cross-cutting relationships can show which of two intersecting scours likely formed later. Differences in surface smoothness or degradation can support a relative-age comparison, but visual appearance alone does not provide an absolute date. Scour populations may reflect different iceberg sources, water depths, substrate conditions or glacial episodes; broader reconstructions based on those patterns remain interpretations that require additional evidence.
