Dried, ground sub- samples were used to determine percent organic matter
using the loss- on-ignition method, where soils were burned at 550\u00b0C in a
muffle furnace for a total of 3 h, then soils were digested with 50 mL of 1 N
HCl at 100 \u00b0C for 30 min, and filtered through Whatman #41 filter paper
for total P analysis (Andersen, 1976). Total P content was then determined
colorimetrically via an AQ2 Automated Discrete Analyzer (Seal Analytical,
Mequon, WI) in accordance with EPA method 365.1 Rev. 2.

Organic Matter Content:

using the loss- on-ignition method, where soils were burned at 550\u00b0C in a
muffle furnace for a total of 3 h.

Extractable Dissolved Organic Carbon:
1 g dry weight of field-moist soil were weighed into 40 mL centrifuge tubes
and extracted with 25 mL of 0.5 M K2SO4, placed in an orbital shaker for 1 h
at 25 \u00b0C and 150 rpm then immediately centrifuged for 10 min at 10
\u00b0C and 5000 rpm. The supernatant was vacuum filtered through Supor 0.45
\u03bcM filters, acidified with double distilled H2SO4 for preservation, and
stored at 4 \u00b0C until analysis. Dissolved organic carbon (DOC) was
determined by use of a Shimadzu TOC-L Analyzer (Kyoto, Japan).

Extractable Nitrate:
2.5 g of wet soil (both from the field and from the bottle incubation) into
40 mL centrifuge tubes and adding 25 mL of 2 M KCl. Samples were then shaken
continuously on an orbital shaker for 1 h at 25 \u00b0C and 150 rpm, then
centrifuged for 10 min at 10 \u00b0C and 5000 rpm. Following the centrifuge,
samples were immediately filtered through Supor 0.45 \u03bcM filters and
acidified with double distilled H2SO4 to a pH of < 2 for preservation.

2.5 g of wet soil (both from the field and from the bottle incubation) into
40 mL centrifuge tubes and adding 25 mL of 2 M KCl. Samples were then shaken
continuously on an orbital shaker for 1 h at 25 \u00b0C and 150 rpm, then
centrifuged for 10 min at 10 \u00b0C and 5000 rpm. Following the centrifuge,
samples were immediately filtered through Supor 0.45 \u03bcM filters and
acidified with double distilled H2SO4 to a pH of < 2 for preservation.
Extractable nutrients samples were then analyzed using an AQ2 Automated
Discrete Analyzer (Seal Analytical, Mequon, WI, EPA methods 231-A Rev.0, 210-A
Rev.1, and 204-A Rev.0).

Microbial Biomass Carbon:
Microbial biomass C (MBC) was determined on soils both immediately after the
field sampling and soils from the bottles after the incubation period
following the method outlined in Vance et al. (1987). Duplicates of
approximately 1 g dry weight of field-moist soil were weighed into 40 mL
centrifuge tubes and assigned to either a fumigate or non-fumigate treatment.
The fumigated samples were exposed to gaseous chloroform for 24 h in a glass
desiccator. After 24 h, the sam- ples were extracted with 25 mL of 0.5 M
K2SO4, placed in an orbital shaker for 1 h at 25 \u00b0C and 150 rpm. After
incubation, samples were immediately centrifuged for 10 min at 10 \u00b0C and
5000 rpm. The supernatant was vacuum filtered through Supor 0.45 \u03bcM
filters, acidified with double distilled H2SO4 for preservation, and stored at
4 \u00b0C until analysis. Non-fumigate samples were processed in the same
manner, excluding the chloroform fumigation. Dissolved organic carbon (DOC)
was determined by use of a Shimadzu TOC-L Analyzer (Kyoto, Japan). Microbial
biomass C was calculated as the difference between the fumigated samples and
the non-fumigated samples.

enzyme activity.

Rate of carbon dioxide production (potential):
Duplicate subsamples (approximately 7 g) from each depth segment of each
core were weighed into 100 mL glass serum bottles, capped with a rubber septa
and aluminum crimp and evacuated to \u221275 mm Hg. Replicate bottles were
randomly assigned to one of two treatments: anaerobic (purged with 99% O2-free
N2 gas for 3 min), or aerobic (purged with Breathing Grade air containing 21%
O2 for 3 min). Anaerobic bottles were injected with 14 mL of filtered,
N2-purged site water, while aerobic bottles were injected with 14 mL of
filtered, breathing air-purged site water. Bottles were then placed on an
orbital shaker at 150 rpm and 25 \u00b0C. Headspace samples were taken at 1,
2, 4, 7, 10, and 14 day time points, and injected into a GC-2014 gas
chromatograph (Shimadzu Instrument, Kyoto, Japan) equipped with a flame
ionization detector. Respiration rates were calculated as the change in CO2
production over time. After each gas sample was extracted from the bottles'
headspace, the bottle was purged with either 99% O2- free N2 gas or Breathing
Grade air for 3 min, depending on treatment.

Rate of nitrate mineralization (potential):
Following the 14 day incubation, bottles were uncapped, and the remaining
soil sample was placed in a 20 mL HDPE scintillation vials

Rate of ammonium mineralization (potential):
for analysis of extractable ammonium (NH4+), nitrate (NO3\u2212), and
soluble reactive phosphorus (SRP), microbial biomass C, and enzyme analysis.

attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:
Coastal Louisiana is currently experiencing net sea level rise at rates higher than most of the world's coastlines and within the global range predicted to occur in the next 65 - 85 years, making Louisiana an ideal site to study potential future impacts of rising sea level on coastal systems. This project will use field collection and controlled tank experiments to study the changing organic carbon cycle resulting from erosion of marsh soils along with its impact on associated biogeochemical processes. The hypothesis tested in this study is that the majority of eroded soil organic carbon is converted to carbon dioxide (CO2) and released to the atmosphere, representing an addition to the anthropogenic input of CO2. This process has not been quantified and could be an important missing component in predictive models of atmospheric CO2 changes. While this process may be of only regional importance today in comparison to other sources of CO2, this study of the Louisiana coast will greatly enhance our full understanding of the potential impacts on the global carbon cycle that may result from coastal erosion as global sea level continues to rise.
The project will train graduate and undergraduate students in interdisciplinary research involving marine and wetland biogeochemistry, microbiology, and ecological modeling. It will also fund development of an interactive, educational display on the loss of coastal wetlands for the Louisiana Sea Grant's annual Ocean Commotion educational event attended by area middle and high school students, teachers, and parents. Results from this study may also inform community planners both regionally and worldwide as they prepare for sea level rise in coastal communities.
Eustatic sea level rise and regional subsidence have created a much greater rate of coastline loss in Louisiana than is being experienced in most of the world's coastal regions, reaching global rates that are predicted to occur worldwide in 65 - 85 years. This provides a unique potential to extrapolate data from Louisiana's changing coastal carbon cycle to both regional and global models of the future impact of sea level rise and coastal erosion. By quantifying and modeling the importance of CO2 emissions resulting directly from mineralized soil organic matter from eroding coastlines, a missing element can be added to climate change models. The PIs here plan to investigate the fate of the coastal wetland carbon pool as it erodes using field sampling, laboratory analysis, mesocosm manipulations, and the creation of a coupled physical-biogeochemical model for the basin being studied. Beyond quantifying increased CO2 emission, the PIs will also address the potential for increased eutrophication due to input of nutrients from eroded soils, as well as the potential for future contribution to existing hypoxic zones in the northern Gulf of Mexico that result from excessive nutrient input from the Mississippi River watershed.
