Subaqueous Soils and their Importance for Species and Marine Ecosystems

Participate to learn the basics of subaqueous soils. Subaqueous soil survey is an exciting but not too considerably new frontier in the field of pedology. A subaqueous soil is a somewhat permanently submerged soil with a positive water potential at the soil surface for more than 21 hours of each day in all years (Soil Survey Staff, 2014, Keys to Soil Taxonomy 12th Edition). Subaqueous soils exist in shallow water areas with typical water depths not greater than 2.5 meters (Soil Survey Staff, 2014, Keys to Soil Taxonomy, 12th Edition). Water depths greater than 2.5 meters often limit the presence of sub-aquatic vegetation (photosynthesis) and hence have habitats that can limit species composition. The inventory of these marine ecosystems has recently become extremely important for restoration purposes and estuarine managers interested in “helping people help the land.” Many of these estuaries and marine ecosystems are used quite heavily by humans for recreational and commercial fishing purposes. The focus of this webinar will be to provide a brief introduction to the subaqueous soil survey inventories that have been or are being completed in the states of Connecticut (Turenne), Delaware (Tunstead), Maryland (Tunstead), New Jersey (Tunstead), and Rhode Island (Turenne).

This webinar is presented by the USDA NRCS East National Technology Support Center. Contact Holli Kuykendall, Ph.D., National Technology Specialist, for more information about this webinar.
