In recent years, pedological research has targeted soils that are permanently under water, subaqueous soils. These are aquatic soils and are outside the extent of terrestrial soil surveys. The water-ward extent of terrestrial soil surveys traditionally ends at the edge of water bodies or where terrestrial vegetation ends. This presents several questions. In our efforts to realize aquatic soil survey, are we ignoring frequently exposed aquatic areas by focusing on subaqueous soils? If the extent of terrestrial soils is the existence of the edge of a water body or the end of terrestrial vegetation, how do we statically delineate such a dynamic feature? We present a series of morphological descriptions of soils along catenas crossing the terrestrial/aquatic border to document the continuum of soil morphology. All soils along these continuums exhibit pedogenesis as indicated by their morphologies. We express our concern pictorially by displaying both fresh water and saline examples of soil areas that would be precluded from subaqueous and terrestrial soil surveys. Do these soil areas represent subaqueous soils or terrestrial soils?
