- Abstract:
-
The U.S. Geological Survey has a long history of responding to and
documenting the impacts of storms along the Nation’s coasts and
incorporating these data into storm impact and coastal change
vulnerability assessments. Although physical changes caused by tropical
and extratropical storms to the sandy beaches and dunes fronting barrier
islands are generally well documented, the interaction between sandy
shoreline erosion and overwash with the back-barrier wetland and
estuarine environments is poorly constrained. The goal of the Barrier
Island and Estuarine Wetland Physical Change Assessment project is to
integrate a wetland-change assessment with existing coastal-change
assessments for the adjacent sandy dunes and beaches, initially focusing
on Assateague Island along the Maryland and Virginia coastline.
Assateague Island was impacted by waves and storm surge associated with
the passage of Hurricane Sandy in October 2012, causing erosion and
overwash along the ocean-facing sandy shoreline as well as erosion and
overwash deposition in the back-barrier and estuarine bay environments.
Data Series 999 associated with this metadata record describes sediment
data collected using sand augers in active overwash zones on Assateague
Island in Maryland. Samples were collected by the U.S. Geological Survey
(USGS) during two surveys in March/April and October 2014 (USGS Field
Activity Numbers [FAN] 2014-301-FA and 2014-322-FA, respectively). The
physical characteristics (for example, sediment texture or bedding
structure) of and spatial differences among these deposits will provide
information about overwash processes and sediment transport from the
sandy barrier-island reaches to the back-barrier environments. Metrics
derived from these data, such as mean grain size or deposit thicknesses,
can be used to ground-truth remote sensing and geophysical data and can
also be incorporated into sediment transport models. Data products,
including sample location tables, descriptive core logs, core
photographs and x-radiographs, the results of sediment grain-size
analyses, and Geographic Information System (GIS) data files with
accompanying formal Federal Geographic Data Committee (FGDC) metadata
can be downloaded from https://pubs.usgs.gov/ds/0999/ds999_data.html.
- Purpose:
-
This zip archive includes the geographic locations, site elevations,
site descriptions, and core and trench metrics in Microsoft Excel, Esri
file geodatabase, and Kehyhole Markup Language (KML) format for sand
auger sites collected from Assateague Island, Maryland in March/April
and October 2014 (USGS FAN 2014-301-FA and 2014-322-FA).
- Supplemental_Information:
-
USGS scientists collected sediment samples from Assateague Island and
Chincoteague Bay during two surveys—one in the spring, March 26 to April
4, 2014, and one in the fall, October 21–30, 2014 (USGS FAN 2014-301-FA
and 2014-322-FA, respectively). Samples were collected from a variety
of depositional environments, including mainland wetlands, back-barrier
wetlands, and sparsely vegetated to unvegetated washover deposits. Site
locations were identified as 14CTB-XXX# where XXX is a consecutive
number from 01 to 500 (01–200 for spring; 300–500 for fall) and #
represents the type of sample collected. Data Series 999 describes
sediment data from sand augers (sample type W) collected from active
overwash zones on Assateague Island.
Sand extents derived from pre- and post-storm aerial imagery were
analyzed to identify areas of Assateague Island that were overwashed
during Hurricane Sandy. Coring sites targeted three active overwash
zones (transects 1, 3, and 4) and one control transect (transect 2).
During the spring survey, a total of 19 cores were collected from 17
sites, including 8 cores from 7 back-barrier marsh sites. During the
fall survey, all of the spring sand auger sites were re-cored, and
additional cores were collected from overwash deposits at transects 1
and 4 located approximately 1 kilometer (km) north of the Verrazano
Bridge Causeway on Sinepuxent Bay and at the Fox Hills Level north of
Green Run Bay, respectively. The expanded sampling strategy targeted
sites that had overwashed historically (since 1989) in addition to those
sites that were overwashed during Hurricane Sandy. In October, a total
of 81 core sections were collected from 69 sites.
All sample locations were recorded at the time of collection with a
Garmin GPSMAP 76S handheld Global Positioning System (GPS) receiver.
Position and elevation data were also recorded with an Ashtech
Differential Global Positioning System (DGPS) receiver and geodetic
antenna, which provided more accurate horizontal and vertical control
than handheld GPS systems. A stop-and-go rapid-static survey technique
was used, with a static occupation duration of 5 minutes at each sample
site. DGPS data were recorded concurrently throughout the survey at
multiple National Park Service (NPS) benchmarks using a similar
instrument combination.
Cores were collected using an AMS sand/loose sediment soil probe, which
can accommodate a 2.54-centimeter(cm) (1-inch) diameter by approximately
60-cm (2-feet) plastic sleeve. In addition to cores collected from the
ground surface, during the October survey a second core was collected at
some sites from a trench dug to just above the groundwater table. The
purpose of collecting a second, deeper, core was to try to penetrate
organic-rich deposits representing the pre-overwash surface below the
washover sediments. Cores from sites where a second core was collected
were identified as 14CTB-XXXW-1 (surface core) and 14CTB-XXXW-2. After
extraction, each core was capped, sealed, and labeled with transect
location, core number, and orientation. The cores were transported to
the USGS St. Petersburg Coastal and Marine Science Center (SPCMSC) for
processing and analysis. During the October survey, shallow trenches
were also dug at each of the transect 1 and 4 washover sites for the
purpose of supplementing washover thickness and sedimentologic data from
the sand augers with additional sediment samples from targeted strata.
Trench depths, however, were limited by a shallow water table, and in
most cases the trenches back filled or collapsed before the pre-overwash
surface could be identified. The site information, along with core and
trench descriptions, is available from https://pubs.usgs.gov/ds/0999/ds999_data.html.

The positional accuracy of the sample locations is determined by the
accuracy of the raw position data recorded by the GPS antenna during
data collection. DGPS coordinates were obtained using post-processing
software packages (National Geodetic Survey On-Line Positioning User
Service, OPUS, and Novatel Waypoint Product Group GrafNav).
- Logical_Consistency_Report:

Position and elevation data at each sample site were recorded with an
Ashtech DGPS receiver and geodetic antenna. DGPS data were recorded
concurrently throughout the survey at multiple NPS benchmarks using a
similar instrument combination. The final sample locations, including
elevation, are the post-processed DGPS coordinates based on processing
to the nearest base station; baseline distances for all sand auger sites
were less than about 6 km.

All static GPS base station sessions were processed through the On-Line
Positioning User Service (OPUS) maintained by the National Geodetic
Survey (NGS). The OPUS base-station solutions were entered into a
spreadsheet to compute a final, time-weighted positional coordinate
(latitude, longitude, and ellipsoid height) for each base station.
Base-station positional error was calculated as the absolute value of
the final position minus the session position value. The maximum
horizontal error of the base station coordinates used for
post-processing the sample locations was 0.00005 seconds latitude and
0.00015 seconds longitude.

final, time-weighted positional coordinate (latitude, longitude, and
ellipsoid height) for each base station. Base-station positional error
for each GPS session was calculated as the absolute value of the final
position minus the session position value. For this survey, the maximum
standard deviation of the base station ellipsoid height was 0.009 m and
the maximum vertical error for the base station was +/- 0.016 m. The
time-weighted average positions were compared with the NPS network
control numbers for each base station; the time-weighted elevations for
each base station occupation were within 2 standard deviations of the
NPS control elevations. The NPS control coordinates were used for
subsequent post processing.

GPS base stations were erected on multiple NPS benchmarks located on the
back-barrier side of Assateague Island. An Ashtech Z-Xtreme DGPS
receiver recorded the 12-channel full-carrier-phase positioning signals
(L1/L2) from satellites via a Thales choke-ring antenna at the base
station. A similar instrument combination (Ashtech Z-Xtreme receiver and
Ashtech geodetic antenna) was used for the rover GPS. The base receiver
and the rover receiver record their positions concurrently at 1- to
5-second (s) recording intervals throughout the survey. A stop-and-go
rapid-static survey technique was used, with a static occupation
duration of 5 minutes at each sample site.

At the SPCMSC sediment laboratory, the cores were split lengthwise,
x-rayed, photographed, described macroscopically using standard
sediment-logging methods, and subsampled at 1.5- to 2-cm intervals for
grain-size analysis. Sample frequencies varied between cores depending
on observed sedimentologic changes. Some cores were sampled at high
frequencies to characterize the washover deposits, whereas in other
cores the sampling strategy was more targeted.
