The continental shelf break typically occurs at depths around 200 meters before descending sharply into the continental slope.
The continental shelf break marks the transition from shallow shelf waters to steep continental slope. Oceanographic features at this boundary enhance prey availability and concentrate marine life. Line-transect and acoustic surveys frequently record Cuvier’s beaked whale presence along these margins. The shelf break provides access to deep foraging grounds without requiring travel far offshore. Detection probability increases because whales must surface periodically above steep bathymetry. Survey data compiled by NOAA and international research groups confirm repeated association with this transition zone. Habitat modeling incorporates bathymetric gradients as predictive variables. Depth proximity shapes visibility. Edge habitats anchor distribution.

Improved detection informs abundance estimation and risk assessment. Environmental impact reviews for coastal infrastructure projects must consider slope-adjacent habitats. Fisheries and naval activity often intersect with these biologically productive areas. Spatial planning depends on understanding habitat concentration. The shelf break becomes both ecological and regulatory boundary. Mapping improves oversight. Geography informs policy.
For observers at sea, a subtle shift in depth contour can mark dramatic change in biodiversity. The irony is cartographic: lines on nautical charts correspond to living corridors for extreme divers. Cuvier’s beaked whales surface briefly along edges invisible from shore. Boundaries beneath the surface define presence. Depth transitions create opportunity. Habitat lies along margins.
