The user should be aware that meteorological events such as hurricanes may alter these depths or may have already have already altered the actual depths from those represented on the source NOAA charts. Furthermore, geomorphological processes due to sediment load are causing landward migration of isocontours at a rate of about 25 meters per year in the Mississippi River Delta Plain area (east and west of where the Mississippi empties out into the Gulf). Because these data are based on historical NOAA charts, the effects of this migration have not been captured.
