BRIEF DESCRIPTION OF DATA FILE: Rhodamine dye and ammonium-nitrate addition at the mouth of the right branch at Sweeney Creek on 12 June 2003.  Samples collected for dye and nitrate concentrations.

KEYWORDS: nitrate, dye addition, rhodamine,

EXPERIMENTAL DESIGN AND METHODS:  Pulse addition of dye-nutrient solution added during the first hour of incoming flood tide.  Samples collected at 2 locations in the main channel of the R branch during the incoming tide.  Additional samples collected at high tide from ditches on the S side (J-ditches) and N-side (B-ditches) of the R branch.  Water samples from the ebbing tide collected at the confluence using an ISCO autosampler.  Nutrient samples filtered in situ and then frozen until time of analysis.  All dye samples run on Turner Flourometer for Rhodamine WT concentration.  Nitrate analysis conducted at the MBL using a Lachat Autoanalyzer according to standard lab procedures (see methods).
