Cross-section from the sand out to open water, split into 2 visibility zones: Post Break (0-200 ft from shore), Open Water (200+ ft from shore).
Shore
Post Break
0-200 ft from shore
Open Water
200+ ft from shore

Post Break: The range past where any waves are forming, where the water starts to have a significant increase in visibility. There might be some sediment here, but swell energy is diffused and the water is calmer.

Open Water: This zone is far out enough from the shore that the water is at its clearest. It’s deep enough that sediment is not disturbed by the wave energy at the surface. Haze can sit near the surface, so the water is usually clearer the deeper you go.

Field notes

About Corona del Mar State Beach

Corona del Mar State Beach is a half-mile sand cove on the south side of the Newport Harbor entrance in Orange County. The east jetty of the harbor closes off the north end of the cove, and sandstone bluffs frame the south. Locally the beach is called Big Corona, the larger counterpart to Little Corona del Mar Beach, which sits roughly 0.3 miles south and is reached by stairs at the end of Poppy Avenue. China Cove tucks in immediately to the west, with stairs descending from Way Lane. The Sherman Library and Gardens sits 0.5 miles inland on Pacific Coast Highway. The beach itself ends about 450 meters north of the Crystal Cove State Marine Conservation Area boundary, so the SMCA take rules do not reach this spot.
