Measurement of the volume of water during lateral exchange measurements in tidal creek systems draining predominantly low-elevation marsh dominated by Sparinta alterniflora (LM1 and LM2) and high-elevation marsh dominated by S. patens (West, Nelson, HM1). Creeks are located in Rowley, MA, PIE LTER.
EXPERIMENTAL DESIGN AND METHODS:
Tidal creeks are occupied for approximately 8-10 hours from the start of flood tide to the following low tide, with water discharge volume measurements made four times every approximately 15 minutes using a towable acoustic doppler current profiler (Teledyne Streampro ADCP) (this dataset), nutrients, suspended solids, and dissolved inorganic carbon (EST-RO-TC-LateralExchange-NUT.xls.xls), and measurement of water-column conductivity, salinity, and dissolved oxygen (EST-RO-TC-LateralExchange-SONDE.xls). A pulley system was placed across the tidal creek to tow the adcp across the creek during measurements. Positive values indicate flood tide discharge, and negative values indicate ebb tide discharge.
