Summary

Salt marshes are grassy wetlands that form along sheltered coastlines. These areas provide crucial habitats for many species of birds and other animals, in addition to recreational activities and economic opportunities. Marshes also protect the coast from storms and filter runoff from the landscape, ensuring cleaner and healthier coastal waters. As climate change causes sea levels to rise salt marshes are at risk of being drowned out if they are unable to grow quickly enough to stay above the rising tides. In order to build elevation and endure sea level rise, marshes trap sediment from tidal waters, which accumulates over time to build a platform that marsh grass can grow on. Along exposed coasts, humans have built seawalls and [...]

descriptionA document to support decisions regarding coastal armoring and saltmarsh restoration will be produced and distributed through NOAA’s Digital Coast suite of tools. The Coastal Sediment Fact Sheet will provide an overview summary of the main findings regarding the impacts of coastal armoring on suspended sediment supply to marshes.
repositoryThis fact sheet will be distributed through NOAA’s Digital Coast tools listings, here: https://coast.noaa.gov/digitalcoast/tools Pending discussions with our advisory committee, we may distribute this tool via other means as well.

descriptionTo assess changing tidal marsh sedimentation in Jamaica Bay, NY, we will rely on publicly available data from the Blue Carbon Atlas, as well as sediment core data shared with the authors by Cathleen Wigand of the EPA for the PIs’ ongoing blue carbon mapping project.

qualityChecksAll data in the Blue Carbon Atlas have been subjected to Smithsonian’s QA/QC procedures.

exclusiveUseProject data and associated products will be made available publicly at the end of the project.
descriptionNew sediment cores associated with this project will be collected during year 1 during one week of field work, with associated lab work also to be completed during year 1. Data from these sediment cores will include down-core elemental abundances, organic content, bulk density, and radionuclides to constrain age. All of these measurements will be made in the PIs’ lab at UMass Amherst. All data will be made public upon completion of the project funding in non-proprietary text (csv) format.
repositoryData will be stored as a new collection in ScienceBase. Soil carbon data will also be uploaded to the Coastal Carbon Atlas: https://ccrcn.shinyapps.io/CoastalCarbonAtlas/
qualityChecksData will be entered into spreadsheets with pre-labeled columns and formulae. Conditional spreadsheet formatting will identify keystroke errors in entering the data that result in erroneous values.
protocolsStandard protocols unfortunately do not exist for the collection of tidal marsh soil characteristics. We will use protocols based on an ongoing project in our lab assessing carbon content of salt marsh soils. These protocols are as follows:1. Split and describe core; 2. Use a 25 mm internal diameter by 27 mm deep hole saw to extract a fixed volume sample for bulk density analysis; 3. Dry the sediment and weigh it to determine the dry bulk density; 4. Combust the sediment for 4 hr at 550 degrees C and record the change in sample mass to determine soil organic matter fraction.
formatData from sediment cores will be recorded and maintained in cloud-based spreadsheets to ensure real time backup of all measurements. Data will be packaged for archive and distribution in plain text CSV format.
restrictionsNone
backupAndStorageAll data will be entered into cloud-based spreadsheets and data storage platforms to assure continuous backup and assure version control.
dataManagementResourcesPI Yellen will oversee data management procedures throughout the project. Our team will rely on University-provided cloud storage and collaboration solutions (OneDrive) to store and manage data. In year three, one half moth of Dr. Yellen’s time will be used to coordinate with graduate student Wenxiu Teng and co-investigators to write metadata and organize data for archiving at USGS’s ScienceBase data repository. We estimate that these activities represent 15% of Dr. Yellen’s time on the project throughout the three years, and 25 % of Mr. Teng’s time in Year 3. In total, the total expected expenditure for data management and archiving is approximately $20,000, or 5% of the total project budget.
volumeEstimate100 MB
dataProcessingSoil organic matter fraction will be calculated as the change in sample mass after burning divided by the total dry sample mass. Dry bulk density will be determined by dry sample mass divided by the volume of our fixed volume hole saw sampler.
