2005 Near shore Profile of the North End of Assateague Island National Seashore

Description:

Abstract:

In association with the North End Restoration project, the USACE collected topographic profiles on the northernmost 13 km of Assateague Island. A sled survey collected elevations from the upper beach to the depth of closure along transects spaced at 0.25 km intervals. Prior permission must be granted from Gregory Bass of the US Army Corps of Engineers, Baltimore District, before this data is distributed.

Purpose:

Beach and near shore profiles are collected to monitor bathymetric and volumetric changes relating to the North End Restoration project, including dredging sand from the ebb tidal delta.

Supplemental_Information:

There is also a near shore profile available of the North End of Assateague Island National Seashore for 2003 and 2004.

Survey sleds may compress a soft seafloor (0.5 cm)or dig into the bottom while under tow. This will produce a bias in the data rather than a random error, and will tend to cancel in a volume change calculation. (See USACE CETN- II-31 (1993).)

Process_Step:

Process_Description:

In association with the North End Restoration project, the USACE collected topographic profiles on the northernmost 13 km of Assateague Island. A sled survey collected elevations from the upper beach to the depth of closure along transects spaced at 0.25 km intervals. A survey sled consists of a survey rod supported on a sled that rides along the sea bottom while being towed. The runners on the sled are normally 10 to 20 feet long, and each bottom elevation reading is an average of the elevation of the end points of the runners.

Elevations in the USACE profiles dataset were referenced to UTM 18 North, NGVD29, meters.

CorpsCon6 was used to convert these points into UTM 18 North, NAVD88, meters. These tables were then concatenated into one table containing all profiles for the year, imported into ArcMap using the 'Add XY Data' Tool, and then exported as shapefile.
