Ocean floor features map. The northwest passage and northern sea route are two important seasonal waterways that connect the atlantic and pacific oceans. The map serves as a tool for. With careful processing small differences in sea surface heights and gravity can reveal detailed maps of the seafloor. This is expensive and time consuming so sonar maps are mostly only made of.

Northwest passage northern sea route. Very little of the ocean floor has been mapped directly. Contour maps for land are called topographic maps. Contour lines connect points on the map with the same elevation to help show changes in elevation.

Even the most detailed maps of the sea floor cannot answer the tantalizing question of what does the sea floor really look like. Shape and distribution of underwater features.
