Modeling particle size distribution for subaqueous soil survey applications Open
Coastal environments face a growing number of challenges as a result of a changing climate (e.g., sea level rise, flooding, and erosion). In response, intertidal and subaqueous soils (SAS) are being mapped to provide a soil resource invent…

Greenhouse Gas Flux in Coastal Salt Marshes: Field Measurements along Estuarine Gradients in Northeastern USA Open
Tidal Marshes are wetland ecosystems at the marine-terrestrial interface which serve as strong sinks for atmospheric carbon dioxide and large reservoirs of soil organic carbon (SOC). However, tidal marsh soils also produce and emit the pot…

Birnessite films are sensitive indicators of microbial manganese reduction in soil Open
Manganese (Mn) and Fe indicator of reduction in soils (IRIS) devices are low‐cost, convenient tools for identifying reducing conditions in soils. Because Mn is reduced at similar redox potentials as nitrate, there is considerable interest …

Carbon sequestration in back‐barrier tidal marsh soils Open
Tidal marshes are broad flat wetlands that have some of the highest carbon stocks of any ecosystem. Although the amount of carbon stored in these soils is undeniable, there are a number of uncertainties regarding carbon sequestration rates…

Manganese‐coated IRIS to document reducing soil conditions Open
Iron‐coated indicatorof reduction in soils (IRIS) devices have been used for nearly two decades to help assess and document reducing conditions in soils, and official guidance has been approved for interpreting these data. Interest in mang…

Abiotic soil properties affecting interpretation of IRIS sensors in tidal and freshwater soils Open
Indicator of Reduction in Soils (IRIS) films are visual sensors used to document weakly or moderately reducing conditions in soils based on the reduction and removal of brown manganese (Mn) oxide or orange iron (Fe) oxide paints, respectiv…

Changing the hierarchical placement of soil moisture regimes in Soil Taxonomy Open
Soil moisture and temperature are incorporated into Soil Taxonomy through the broad classes of moisture and temperature regimes. Although both are important variables in soil formation and land use, soil temperature regime (STR) is typical…

Impacts of Oyster Aquaculture on Subaqueous Soils and Infauna Open
Oyster aquaculture maintains water quality via filter‐feeding processes; however, few studies have investigated the impacts of resulting biodeposits on the underlying soils. In this study, we investigated the impacts of oyster aquaculture …

Pollen Preservation in Alluvial Soils: Implications for Paleoecology and Land Use Studies Open
Core Ideas Floodplain soils preserve pollen that can reconstruct past climate and land uses. Pre‐evaluation of soil properties will save future researchers time and money. Alluvial pollen preservation data expand where paleoecology studies…
View article: Connectivity and Nitrate Uptake Potential of Intermittent Streams in the Northeast USA
Connectivity and Nitrate Uptake Potential of Intermittent Streams in the Northeast USA Open
Non-perennial streams dominate the extent of stream networks worldwide. Intermittent streams can provide ecosystem services to the entire network—including nitrate uptake to alleviate eutrophication of coastal waters—and are threatened by …

Assessing Dynamic Soil Properties in Southern New England Forests within an Ecological Site Framework Open
Core Ideas Coniferous and deciduous forests are two common states within a glaciofluvial upland ecological site. Upland soils with contrasting particle size showed similar ecological potential. Poorly drained and very poorly drained ripari…

Mapping Freshwater Subaqueous Soil Resources: Examples from Southern New England Open
Core Ideas Soil series were developed for Humaquepts, Frasiwassists, and Psammentic and Aeric Frasiwassents. GPR technology provided accurate analysis of water depth, substrate type, and organic thickness. We identified five soil‐landscape…
View article: Impacts of fundamental changes to Soil Taxonomy
Impacts of fundamental changes to Soil Taxonomy Open
Soil Taxonomy is one of the dominant soil classification systems in the world, but has undergone revisions on a regular basis since 1983. It is larger and some parts have become difficult to apply without considerable experience. Some pedo…

Soil taxonomy proposals for acid sulfate soils and subaqueous soils raised by the 8th International Acid Sulfate Soils Conference Open
The 8th International Acid Sulfate Soils Conference presented examples and discussions for classification of ‘acid sulfate soils’ and related issues for ‘subaqueous soils’. When these soils are disturbed or exposed, the sulfides (predomina…

Soil Color and US Northeast Aquods Open
Core Ideas Identifying hydric soils and depth to seasonal high water table is difficult in Spodosols. The specific criteria for classifying wet Spodosols need to change. Extractable Fe does not appear to contribute to the red color of wet …
