Regional learning map. GEBCO says this grid must not be used for navigation or safety at sea. It does not establish beach depth, currents, access, a marina entrance or a home boundary.

Coast referenceDepth contours

Shallower3,000 m

Cell colours preserve the model values. Contour lines interpolate between grid centres. The coast reference and model cells have different resolutions.

Follow the section.

114 sea cells along 77.4 km of the grid. Deepest model value in this section: 2,636 m.

The profile retains source values and leaves land gaps empty. Its display makes depth changes visible; horizontal and vertical scales differ. No swimming depth, tide level or safe route is inferred.

WHAT SUPPORTS THE GRID?

Source type is useful.
It is not an accuracy score.

The companion source grid gives a category for each cell. It does not supply a local error range, survey date, present water depth or guarantee of a safe passage.

The counts include the whole rectangular window, including land. They are cell counts, not a measured percentage of the ocean or a city-completion figure.

Original 3D regional seabed overview from GEBCO source samples, with vertical height stretched six times — 3D overview uses every third source cell, with the final row and column retained. Triangles interpolate between those samples; blocks containing land are omitted. Height is stretched 6× to make the offshore shape easier to see. Coast reference is drawn at zero model height. This is a regional model, not a current seabed survey.

Data, dates and map method

GEBCO 2026 is a compiled global model. Its release date is not the observation date of every value. This window was extracted from the original elevation and Type Identifier grids at the same 168 rows and 168 columns. All original signed heights, source codes and centre coordinates are retained in the data download.

GEBCO identifies its geographic grid as EPSG:4326 and assumes WGS84. Heights refer to the source’s sea-level reference; some shallow-water source data may use another vertical reference. A 15 arc-second grid interval is about 400–460 metres here. It is sample spacing, not a promise of accuracy.

The map places cells at their published centres, with west/east display scale adjusted at 31.35° N. Distances in sections use great-circle calculations between consecutive source centres. Contours are calculated from the grid; they are not independent soundings. OpenStreetMap shoreline is a separate orientation reference. Differences between its line and coarse cells do not prove shoreline change.
