Description:

Abstract:

The influence of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable in both space and time and depends on a number of climatic, geologic, and physical variables. The impacts storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added during storms or other events helps to abate pressure from sea-level rise. However, if the volume of sediment is large and the resulting deposits thick, the organic substrate may compact causing submergence and a loss in elevation. Similarly, thick deposits of coarse inorganic sediment may also alter the hydrology of the site and impede vegetative processes. Alternative impacts associated with storms include shoreline erosion at the marsh edge as well as potential emergence. Predicting the outcome of these various responses and potential long-term implications can be obtained from a systematic assessment of both historical and recent event deposits. The objectives of this study are to 1) characterize the surficial sediment of the relict to recent washover fans and back-barrier marshes, and 2) characterize the sediment of 6 marsh cores from the back-barrier marshes and a single marsh island core near the mainland. These geologic data will be integrated with other remote sensing data collected along Assateague Island, Maryland / Virginia and assimilated into an assessment of coastal wetland response to storms.

Purpose:

The file includes all bulk lithologic analysis results from marsh and sandy overwash surface sediments collected on Assateague Island and the mainland of Maryland and Virginia in March/April and October 2014 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center.

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, date collected, 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 Assateague Island surficial sediment seasonal comparison archive.

Lineage:

Process_Step:

Process_Description:

In the field, the top 1-centimeter of undisturbed surface material was subsampled for sediment characterization, placed in individual storage bags, and stored on ice. The surface samples were transported to the USGS SPCMSC.

Process_Step:

Process_Description:

In the laboratory, samples were homogenized in the sample bag and a subsample of each 1-cm interval was processed for basic sediment characteristics (dry bulk density and porosity). Water content, porosity and dry bulk density were determined using water mass lost during drying. Approximately 20 – 30 milliliters (mL) of each wet subsample was packed into a graduated syringe with 0.5 mL resolution. The wet sediment was then extracted into a pre-weighed aluminum tray and the weight of the wet sediment was recorded. The wet sediment and tray were placed in a drying oven for approximately 48 hours at 60°C. Water content (θ ) was determined as the mass of water (mass lost when dried) relative to the initial wet sediment mass. Porosity was estimated from the report equation in the document. Salt-mass contributions were removed from the porosity values under the assumption that pore water salinity was equivalent to average salinity of 25. Dry bulk density was calculated from the report equation in the document.

Process_Step:

Process_Description:

Organic matter (OM) content was determined using a similar mass loss technique, commonly referred to as loss on ignition (LOI). The dry sediment from the processing described above was homogenized using a porcelain mortar and pestle. Approximately 1 – 5 grams (g) of dry sediment was placed into a pre-weighed porcelain crucible. The mass of the dried sediment was recorded with an analytical balance to a precision of 0.01 g. The samples were then placed into a laboratory muffle furnace with stabilizing temperature control. The furnace was ramped to 110°C over a 30 minute interval and then held at 110°C for 2 hours. Samples were removed and weighed to determine excess moisture loss. Samples were then placed back in the furnace. The furnace was then ramped to 550°C over a 30 minute interval and then held at 550°C for 6 hours. The furnace temperature was then lowered to 60°C and held at this temperature until the sediments could be reweighed. The latter step prevents the absorption of moisture, which can affect the measurement. Samples were reweighed using the same balance and to a precision of 0.01 g. The mass lost during the 6 hour baking period relative to the initial dry mass is used as a metric of OM content (modified from Dean, 1974). Data are reported as a ratio of mass (milligrams, mg) of organic matter to mass (g) of dry sediment (post-110 oC drying).
