Assessment Of Soil Protein And Refractory Soil Organic Matter Across Two Chronosequences Of Newly Developing Marshes In Coastal Louisiana, Usa, Stuart Alexander Mcclellan

LSU Doctoral Dissertations

The impacts of sea-level rise and hydrologic manipulation are threatening the stability of coastal marshes throughout the world, thereby increasing the potential for re-mineralization of soil organic matter (SOM) in these systems. Such threats have prompted marsh restoration efforts, particularly in coastal Louisiana, yet it is unclear how the slowly decomposing (refractory) and quickly decomposing (labile) fractions of SOM may be differentially affected by different approaches to marsh restoration. Additionally, otherwise labile compounds may accumulate in the soil via a range of protective mechanisms, including rapid burial and association with organic compounds that are thought to enhance soil aggregation, such …

Top 30 Cm Soil C Org Stocks, Isotopic C Org Signature (13dc) And Fine Sediment Content (Silt And Clay %) Estimated In Soil Cores Sampled In Seagrass Meadows Around Australia [Dataset], Ines Mazarrasa, Paul Lavery, Carlos M. Duarte, Anna Lafratta, Catherine E. Lovelock, Peter I. Macreadie, Jimena Samper-Villarreal, Cristian Salinas, Christian Sanders, Stacey Trevathan-Tackett, Mary Young, Andy Steven, Oscar Serrano

Research Datasets

This database contains data on top 30 cm soil biogeochemical properties from soil cores (minimum length of 30 cm) sampled in seagrass (n=201 cores) and adjacent unvegetated patches (n=39) around Australia.

Average biogeochemical properties per core along with information about type of environment, biotic characteristics and environmental conditions.

In particular, the variables included in sheet 1 are:

- Core ID (column A): core code

- Location (column B): name of the region of the sampling site.

- Latitude / Longitude (columns C, D): latitude and longitude

- Bioregion (column E): classified the sampling sites according to …
