Science / Tides and Currents / Progressive Wave: A wave that advances in distance along the sea surface or at some intermediate depth. Although the wave form itself travels significant distances, the water particles that make up the wave merely describe circular (in relatively deep water) or elliptical (in relatively shallow water) orbits. With high, steep, wind waves, a small overlap in the orbital motion becomes significant. This overlapping gives rise to a small net mass transport. See long shore current and rip current. Progressive waves can be internal, traveling along a sharp density discontinuity, such as the thermocline, or in a layer of gradually changing density (vertically).
