What is a primary limitation of using point-by-point sounding?

Using point-by-point sounding primarily involves taking individual depth measurements at specific locations, which can lead to inaccuracies in representing the overall topography of the seafloor. This method provides detailed data for discrete points but fails to offer a continuous view of the underwater landscape. Consequently, certain features or variations between the measurement points can be missed, resulting in a fragmented and potentially misleading understanding of the seafloor's complexity.

The nature of point-by-point sounding means that any variations in the seafloor between readings might not be accurately captured, making it difficult to depict broader geospatial features such as ridges, valleys, or hazards effectively. This limitation highlights the importance of complementary survey techniques that can provide a more comprehensive view of underwater terrain.
