BRIEF DESCRIPTION OF DATA FILE: Rhodamine dye concentration transects (distances in meters from Parker River Dam) measured at high tide. Tidal cycle 1 is first high tide after addition of the dye.

KEYWORDS: advection, dispersion, exchange, dye, transect

SITE TYPE: Estuary

RESEARCH LOCATION: Parker River Estuary

EXPERIMENTAL DESIGN AND METHODS:

Rhodamine dye was added to the Parker River Plum Island Sound Estuary on three dates: 8/4/93, 4/10/95, and 6/25/96. 1.6, 7.7, and 7.7 l of dye was added, respectively, to the estuary about 1.7 km from the dam during high tide. The dye was allowed to mix for one tidal cycle before measurement. All transects were conducted during high tide unless otherwise noted using a flourometer mounted on a boat.

NOTES AND COMMENTS:

VARIABLE DESCRIPTION:

ADD DATE = date dye was added (dd-mmm-yyyy)

TIDE = tidal cycle from addition [addition is tidal cycle 0; each numeral is one high tide cycle; decimals denote sampling not on high tide (i.e., 5.5 is on the low tide after the fifth high tide from addition)]

DIST = distance from Parker Dam (m)

DYE = dye concentration (ppb by volume)
