Figure 3: Surface-elevation table rod depth compared to the depth of the Pleistocene-Holocene contact in coastal Louisiana.
From: Vulnerability of Louisiana’s coastal wetlands to present-day rates of relative sea-level rise
Depths are with respect to North American Vertical Datum of 1988. Because the surface elevation at the 274 sites used in this study ranges from −0.2 to 0.6 m, the map43 can be interpreted as a Holocene isopach map. Scale bar, 50 km.
