Project Description and Goals

RESEARCH QUESTIONS AND HYPOTHESES

The project is designed to determine spatial and temporal variability in water quality parameters, particularly the distribution of dissolved nutrients, suspended material and algal biomass in the tidal creeks of Northampton County.

Project Methods

Field protocols and analytical procedures are described in the attached technical handbook.

Primary water quality parameters will be measured continously in selected sites on the bayside (Nassawadox Creek / Cherrystone Creek) and the seaside (Phillips Creek / Red Bank Creek) with HYDROLAB H20 water quality transmitters. The variability in turbidity will be determined using submersible PAR sensors designed to estimate light extinction coefficients.
