The sampling efforts were part of a larger U.S. Geological Survey study to assess the effects of storm events on sediment distribution. The objective of this study was to characterize the sediments of Chincoteague Bay in order to create baseline conditions to incorporate with hydrodynamic and sediment transport models in order to evaluate pre- and post-storm (Hurricane Sandy) change. This report serves as an archive for sedimentological data derived from the surface sediment. Data are available for a seasonal comparison between March/April 2014 and October 2014. Downloadable data are available as Excel spreadsheets (sediment samples) and as JPEG files (maps). Additional files include: detailed results of sediment grain size analyses, and formal Federal Geographic Data Committee metadata (data downloads). Purpose: The 14CTB_Spring and Fall_Shear Stress.xlsx.zip file includes all bulk lithologic analysis results from lagoonal surface sediments collected in Chincoteague Bay in March/April and 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).

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The physical parameters reported in the tables were analyzed at the USGS SPCMSC sedimentology lab. These lithologic data have not been independently verified for accuracy. Replicate analyses of loss on ignition are reported for quality assurance. Logical_Consistency_Report: The data includes sample ID, water content, dry bulk density, porosity, and loss on ignition. Completeness_Report: This is a complete, processed physical parameters data file for the spring and fall 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.

The sediment parameters subsample from each sample location was processed for basic sediment characteristics: dry bulk density and porosity. Water content, porosity, and dry bulk density were calculated by determining water mass lost during drying. Known volumes of each wet subsample, usually 20 – 30 mL, were packed into a graduated syringe with 0.5 cm-3 resolution. The wet sediment was then extracted into a pre-weighed aluminum tray and the wet sediment's weight was recorded. The wet sediment and tray were placed in a drying oven for 48 hours at 60 °C. Water content was determined as the mass of water (lost when dried) relative to the initial wet sediment mass. Porosity was estimated from the report equation in the document (http://pubs.usgs.gov/of/2015/1219/ofr2015-1219_methods.html). Salt-mass contributions were removed based on the salinity measured at the time of sample collection. If salinity was not measured in the field, pore water salinity was estimated to be 25. Dry bulk density was calculated from the report equation in the document (http://pubs.usgs.gov/of/2015/1219/ofr2015-1219_methods.html).

The dry sediment from the previous process was homogenized with a porcelain mortar and pestle. Approximately 5 grams of the dry sediment was placed into a pre-weighed porcelain crucible. The mass of the dried sediment was recorded with a precision of 0.01 g on an analytical balance. The sample was then placed inside a laboratory muffle furnace with stabilizing temperature control. The furnace was heated to 110 °C for a minimum of 6 hours to remove hygroscopic water absorbed onto the sediment particles. The furnace temperature was then lowered to 60 °C, at which point the sediments could be reweighed. The dried sediment was returned to the muffle furnace. The furnace was heated to 550 °C over 30 minutes and kept at 550 °C for 6 hours. The furnace temperature was then lowered to 60 °C, at which point the sediments could be reweighed. The mass lost during the 6 hour baking period relative to the 110 °C-dried mass is used as a metric of organic matter content.
