BRIEF DESCRIPTION OF DATA FILE: Surface elevation table (SET) raw data from 4 sites along the Rowley River.

KEYWORDS: Surface elevation table, SET, Sedimentation, Accretion, Marker Horizons,

SITE TYPE: Marsh

RESEARCH LOCATION: Latitude and Longitude reported as decimal degrees in the NAD 83 Datum. Elevation is reported as NAVD 88, orthometric height (meters), and is currently an unprocessed measurement of the SET insert pipe. For more information please contact Corey Lawrence (clawrence@mbl.edu). Locations for Levine’s SET 2-3 are not available at this time.

EXPERIMENTAL DESIGN AND METHODS: SET sites are measured each spring and fall using a custom built surface elevation table. Measurement are made are of the height of brass pins above the table. Relative changes in the surface elevation of the marsh can be calculated from the change of pin height overtime.

Each SET has 6 positions relative to the location of the marker horizon (A-F). At each position there are 9 pins dropped to the marsh surface. The bearing of each position in relation to magnetic north is also recorded. For more information on SET and Marker Horizons see: http://www.pwrc.usgs.gov/resshow/cahoon/

NOTES AND COMMENTS: This data is in a raw unprocessed format. Please note that the “SET position” in the data is a reference to the orientation of the SET table at each site. Position “A” refers to the orientation of the SET facing directly at the Marker Horizon plot, subsequent lettering continues in the clockwise direction.
