BRIEF DESCRIPTION OF DATA FILE: Eight SF6 concentration transects along the Parker River Plum Island Sound Estuary after the addition of SF6 to the estuary, and wind speed over the course of the study.

KEYWORDS: advection, dispersion, exchange, transect, wind, SF6, gas

SITE TYPE: Estuary

RESEARCH LOCATION: Parker River Estuary

EXPERIMENTAL DESIGN AND METHODS:

In July, 1996, at a slack high tide, we injected ~0.004 moles of SF6 into the upper Parker River estuary. We added rhodamine dye at the same time in order to locate the tracer plume with an in situ fluorometer. The tracer was allowed to mix for one tidal cycle and we then sampled SF6 concentration in the water at each of seven successive high tides, and once again four days later. Surface water samples were drawn into 100 ml glass syringes, transported submerged in river water to a field laboratory, and analyzed within 6 hours using gas chromatography with electron capture detection. Wind speed was meaured using a continuously recording anomometer installed on the high marsh adjacent to the tracer addition site.
