“…During this process, soil surveyors develop soil map units, conceptual groups of individual mapped polygons (i.e., delineations) that consist predominantly of one or a few soil taxa (Young et al, 1997). New soil taxa are developed if observed soils do not correspond well to existing soil taxa (Balduff, 2007;Stolt & Needelman, 2015;Wessel et al, 2018). Soil taxa covary with the factors and process of soil formation; therefore, soil map units represent portions of the landscape that can be delineated using geologic data, topographic data (and derivatives like topographic indexes), climate data, and the distribution of vegetation and other organisms; all of these data are considered in the context of how they change through time.…”

RhodeRiver, a subestuary on the western shore of Chesapeake Bay, contains a diverse array of subaqueous soils that range from submerged paleosols to fine-textured fluid soils and organic soils. A subaqueous soil survey was completed for the Rhode River subestuary by collecting bathymetric data, delineating landforms, and sampling and describing soils across the submerged landscape. Soil map units were developed by correlating soil properties and taxonomic classification with delineated landforms, resulting in the development of seven proposed soil series corresponding to new soil map units. Geologic maps and other supporting information about the dominant factors of soil formation in this landscape were used with the soil survey of Rhode River to develop a conceptual subaqueous soil-landscape model of soil genesis to explain the origin and distribution of soils in Rhode River. This is the first time that a subaqueous soil-landscape model has been developed for the flooded river valley geomorphic setting of Chesapeake Bay, and it will assist subaqueous soil surveys in other western shore Chesapeake Bay subestuaries and similar environmental settings where upland environments have been or are currently submerging.

“…The lack of comprehensive maps results in a paucity of data related to the extent of these soil materials. However, the benefits of mapping subaqueous and nearshore soil environments have been recognized, and more information about the distribution of acid sulfate soils is anticipated in the future (Wessel et al 2018).

Potential acid sulfate soils include materials with the capacity to generate acidity under certain environmental conditions. As such, these soils can pose challenges to ecological restoration projects occurring in wetlands and nearshore environments. To provide guidance for ecosystem restoration practitioners, the following technical note describes acid sulfate soil formation and distribution and then describes techniques for identifying and monitoring acid sulfate soil conditions prior to and following implementation of restoration activities. Finally, this technical note outlines a number of tools and recently published resources to help avoid unintended consequences of acid sulfate soil disturbance and achieve ecological restoration objectives.

“…Early subaqueous soil surveys studied subaqueous soil forming factors and described the relationships between those factors and soil characteristics (Balduff, 2007;Bradley & Stolt, 2003;Ellis, 2006;Osher & Flannagan, 2007). There are many applications of subaqueous soils information in coastal zone management, related to aquaculture (Still, 2016), submerged aquatic vegetation health (Balduff, 2007;Bradley & Stolt, 2006;Ellis, 2006); moorings (Surabian, 2007); identification of potential acid sulfate soils and other environmental hazards (Wessel & Rabenhorst, 2017;Wessel et al, 2018), management of dredge material (Cornwell et al, 2020;Staver et al, 2020); and carbon accounting (Millar et al, 2015). Initially, subaqueous soil surveys limited their scope to areas with a water depth of approximately 2.5 m or less based on the definition of soil in Keys to Soil Taxonomy (Soil Survey Staff, 2014).…”

Using a subaqueous soil-landscape conceptual model previously developed in an adjacent subestuary, a subaqueous soil survey was undertaken for the South River subestuary of Chesapeake Bay. Using available bathymetry, subaqueous landforms and soil map units were delineated prior to the initiation of any field work. To evaluate the predictive usefulness of the conceptual model, the study area was subsequently sampled at 52 points along specified transects. The soils were described and classified, and the observed soils were compared to the predicted soils from the model using a bootstrapping analysis approach. We concluded that the conceptual model did provide significant positive guidance to generate a useful soil map in South River, by successfully predicting the distribution of soil material types. It did not, however, address the distribution of hypersulfidic materials prevalent in South River soils. The additional information gained on the soils and pedogenic processes gained during this study were incorporated into the final soil survey for the subestuary, and they were also used to refine the soil-landscape conceptual model to improve its potential usefulness in future mapping of western shore subestuaries of Chesapeake Bay.
