Definition:

A line connecting points of equal water depth which is sometimes significantly displaced outside of soundings, symbols and other chart detail for clarity as well as generalization. Depth contours, the refore, often represent an approximate location of the line of equal depth as related to the surveyed line delineated on the source. Also referred to as depth curve.
