Fate of Coastal Wetland Carbon Under Increasing Sea Level Rise: Using the Subsiding Louisiana Coast as a Proxy for Future World-Wide Sea Level Projections https://osprey.bco-dmo.org/project/670520 Fate of Coastal Wetland Carbon Under Increasing Sea Level Rise: Using the Subsiding Louisiana Coast as a Proxy for Future World-Wide Sea Level Projections <p><em>Description from NSF award abstract:</em><br /> 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.</p> <p>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.</p> <p>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.</p> Submerged Wetland Carbon largerWorkCitation project eng; USA oceans -89.8998 -89.8998 29.443547 29.443547 2018-06-01 2018-06-30 Coastal Lousiana 0 BCO-DMO catalogue of parameters from Nutrient properties of coastal wetland soil cores collected in June 2018 from Barataria Bay, Louisiana Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/840534.rdf Name: Location Units: unitless Description: <p>Site location (29°26_36.77__ N, 89°53_59.28__ W)</p> http://lod.bco-dmo.org/id/dataset-parameter/840535.rdf Name: Distance Units: meters (m) Description: <p>Distance from marsh edge</p> http://lod.bco-dmo.org/id/dataset-parameter/840536.rdf Name: Replicate Units: unitless Description: <p>Denotation of whether core was the 1st (A), 2nd (B), or 3rd (C) core pulled from the site as field replicate.</p> http://lod.bco-dmo.org/id/dataset-parameter/840537.rdf Name: Depth Units: centimeters (cm) Description: <p>Soil depth below the surface.</p> http://lod.bco-dmo.org/id/dataset-parameter/840538.rdf Name: Extractable_Nitrate Units: miligrams per kilometer (mg kg-1) Description: <p>Concentration of extractable nitrate within a soil sample.</p> http://lod.bco-dmo.org/id/dataset-parameter/840539.rdf Name: Extractable_SRP Units: miligrams per kilometer (mg kg-1) Description: <p>Concentration of extractable soluble reactive phosphorous within a soil sample.</p> http://lod.bco-dmo.org/id/dataset-parameter/840540.rdf Name: Extractable_Ammonium Units: miligrams per kilometer (mg kg-1) Description: <p>Concentration of extractable ammonium within a soil sample.</p> http://lod.bco-dmo.org/id/dataset-parameter/840541.rdf Name: Latitude Units: decimal degrees Description: <p>Latitude</p> http://lod.bco-dmo.org/id/dataset-parameter/840542.rdf Name: Longitude Units: decimal degress Description: <p>Longitude (west is negative)</p> http://lod.bco-dmo.org/id/dataset-parameter/851549.rdf Name: Date_collected Units: unitless Description: <p>Date of sample collection</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 9273 https://darchive.mblwhoilibrary.org/bitstream/1912/27153/1/dataset-840293_nutrients__v1.tsv download https://doi.org/10.26008/1912/bco-dmo.840293.1 download onLine dataset &lt;p&gt;Nine coastal wetland soil cores were collected in June 2018 from Barataria Bay, Louisiana, a shallow open water basin located west of the Mississippi River Delta.&amp;nbsp;&amp;nbsp;Soil cores were collected along three transects, roughly 1 meter apart, that consisted of three points:&amp;nbsp; the coastal fringe (0 m inland), 1 meter inland, and 2 meters inland.

The Shapiro-Wilk test was used to verify assumptions of normality, and a logarithmic transformation was performed on all datasets. &amp;nbsp;Levene’s test was used to determine homogeneity of variance. A linear mixed-effect model (package ‘lmer’) was used to test the following predictor variables: depth, distance inland, and the interaction of depth and distance inland on the samples collected from the marsh. Transect was included as a random effect. Distance inland was found to be a non-significant predictor variable for all parameters except for extractable NH4+. As such, distance inland and the interaction of depth and distance was removed as a predictor variable from models except extractable NH4+. Isotopic determinations and quantitative PCR analysis was performed exclusively on the three replicate cores taken 1 m inland, and thus depth was the only predictor variable tested for those parameters. Following determination of significance within one of the predictor variables, the package ‘lsmeans’ was used for post-hoc pairwise comparisons using the Tukey method.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;BCO-DMO processing:&lt;/strong&gt;&lt;br /&gt; -&amp;nbsp;Added a conventional header with dataset name, PI names, version date&lt;br /&gt; -&amp;nbsp;Adjusted parameter names to comply with database requirements.&amp;nbsp;&lt;br /&gt; -&amp;nbsp;Units removed and added to Parameter Description metadata section.&lt;br /&gt; - Added Latitude and Longitude columns, converted DMS to DD&lt;br /&gt; - Added column for Date of sample collection&lt;br /&gt; - Missing data entries replaced with 'nd'&lt;/p&gt; Specified by the Principal Investigator(s) asNeeded 7.x-1.1 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact PI Supplied Instrument Name: Instrument Name: Centrifuge Instrument Short Name: Instrument Description: A machine with a rapidly rotating container that applies centrifugal force to its contents, typically to separate fluids of different densities (e.g., cream from milk) or liquids from solids.
