Two graphic maps contrast disturbed and undisturbed Holocene sediment

A Map of disturbed or “reworked” Holocene sediment thickness illustrates the influence of shoreface-attached sand ridges and landward thickening shoreface on overall thickness patterns. The noticeable northwest-to-southeast trend reflects shoreface-attached sand ridge thickness. The sediment contained in the nearshore-bar system is partially reflected along the landward edge of this map. B The T1 isopach map illustrates the thickness of undisturbed Holocene sediment which thins west to east.
