Surveys of Living Shoreline at Sherman Creek, 2019-2023

Results of continuous-flow core incubations to determine nitrogen-removal services before and after the creation of a living shoreline at Sherman Creek Park (New York, NY, USA). Data include surveys pre-restoration (2019), post-restoration (2020), and post installation of enhanced goose-exclusion fencing (2023). The restored marsh is compared to existing (remnant) marsh, rip rap, and mudflat habitats at the same location. Variables measured include dissolved gases (N2, O2), dissolved nutrients (NO3- + NO2-, NO2-, NH3, and PO43-), sediment characteristics (bulk density, moisture content, organic content, porosity, percent carbon, percent nitrogen, and C:N ratio), and vegetation characteristics (above- and belowground biomass, stem height, stem density, stem diameter, leaf width, aboveground C and N, belowground C and N).
For more information on survey methods and flux calculations, download and view metadata html file. Complete flux calculations performed in the R programming language, from instrument output to final fluxes, are detailed. The files in the "data_final" folder are processed and ready for use. (As noted in the metadata, 48 h gas fluxes from 2023 should be interpreted with caution because flow rates became variable prior to 48 h sample collection.) Raw data used in calculations are available in the "raw_data_20XX" folders for each of the three sampling years.
