The concept of gathering coastal zone and subaqueous soil survey data is not revolutionary but rather evolutionary. Initially, soil survey publications along the immediate coast overlooked many coastal soil areas and focused on "agricultural lands." Sparse soil survey work done through the National Cooperative Soil Survey (NCSS) and continuous ongoing research by Universities since the 1990's has developed advanced mapping and classification protocols in coastal zone areas. Recent work has provided new updates to soil survey information along the coast, but still not to the extent or volume of information that is associated with subaerial soil surveys.
Coastal Zone Soil Surveys (CZSS) are soil inventory maps of nearshore or subaqueous soils (permanently submerged), along with adjacent subaerial / terrestrial soils which include tidal marshes, barrier islands / beaches, and some near lagoon mainland upland (non-hydric) areas. The current need for timely and reliable CZSS data such as spatial mapping, tabular data, blue carbon stocks and interpretations is widely recognized as critical for mitigating hazards, creating resources inventories, guiding restoration efforts, and tracking environmental changes. A major limitation to science-based management of shallow water habitats and near shore areas has been a lack of definitive information on the properties and spatial distribution of subaqueous and tidal marsh soils as well as more detailed soil data on adjacent terrestrial areas.
This presentation will highlight the how and why of CZSS and blue carbon mapping along with proposals for mitigating sea-level rise and saltwater intrusion in agricultural areas.
