Surplus surface sediment was analyzed for metals, percent carbon and nitrogen, d13C, and d15N as part of a complementary U.S. Geological Survey Coastal and Marine Geology Program Sea-level and Storm Impacts on Estuarine Environments and Shorelines project study. The geochemical subsample analyzed for metals and stable isotopes at each site may be used for comparison with past data sets, to create a modern baseline of the natural distribution of the area, to understand seasonal variability as it relates to the health of the local environment, and to assess marsh-to-bay interactions. The use of metals, stable carbon, and stable nitrogen isotopes allows for a more cohesive snapshot of factors influencing the environment and could aid in tracking environmental change. This report serves as an archive for chemical data derived from the surface sediment. Data are available for a seasonal comparison between the March–April 2014 and October 2014 sampling trips. Downloadable data are available as Microsoft Excel spreadsheets. Additional files include formal Federal Geographic Data Committee metadata (data downloads). Purpose: The 14CTB_Raw_Fall_CN_G_Data.zip file includes all fumigated and unfumigated bulk and stable carbon and nitrogen isotope values from lagoonal surface sediments collected in Chincoteague Bay in October 2014 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center. Supplemental_Information: This publication contains data for two field activities conducted in 2014: Spring March 26–April 4, 2014 (14CTB01); and fall October 21–30, 2014 (14CTB02).

These data were not independently verified for accuracy. Replicate analyses of all parameters are presented for quality assurance. Logical_Consistency_Report: The data includes sample ID, latitude, longitude, packing material, sample weight, d15N, d13C, percent nitrogen, percent carbon, carbon nitrogen ratio and comments from the lab about the sample. Completeness_Report: This is a complete, processed carbon and nitrogen data file for the fall for a Chincoteague Bay seasonal comparison archive. Lineage: Process_Step: Process_Description: At each sample location, the top 1 cm of the recovered, undisturbed surface material from the Ponar grab was subsampled for sediment characterization, placed in individual storage bags, and stored on ice. The surface samples were transported to the USGS SPCMSC.

Dried and homogenized sediment was placed in 8 x 5 millimeter (mm) silver capsules, wet with 50 microliters (µL) of deionized water, and fumigated in a desiccator with 100 mL of concentrated hydrochloric acid for 6 hours to remove inorganic carbon (Harris and others, 2001). Samples were then dried at 60 °C overnight, and double encapsulated in tin for combustion purposes. Unfumigated sediment samples were also submitted for percent carbon, percent nitrogen, carbon-nitrogen ratio, d13C, and d15N by way of dried and homogenized sediments submitted in tin capsules. All samples were analyzed using a Costech ESC 4010 Elemental Combustion System interfaced with a Thermo Finnigan DELTAplus Advantage isotope ratio mass spectrometer. Values are relative to international standards: the VPDB (Vienna Pee Dee Belemnite) for carbon, and air for nitrogen. The standard deviation of the provided values is estimated at ±0.4 per mille.
