This section contains methods for the general project. The basic monitoring program will be conducted in Old Plantation Creek, Cherrystone Creek, Sand Shoal Channel, Phillips Creek and Machipongo River. Three or four sampling stations will be established at the selected creeks with samples collected every four weeks during the cold part of the year and every two weeks during June to August. Upstream and downstream stations will be sampled to determine spatial variability in paramaters within each creek or site. During each sampling period, water samples will be collected in clean containers and then iced down to minimize microbial activity. After collecting ancillary water quality parameters, such as temperature, salinity, pH, dissolved oxygen, transparency, depth and tidal stage, samples will be brought to the LTER laboratory in Oyster, Virginia and analyzed for the following dissolved nutrients: ammonium, nitrate, nitrite and phosphate. Subsamples will be collected and analyzed for BOD, total suspended solids and chlorophyll content. 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. This section contains a progress report on the general project.

Baseline information on water quality will be collected through a monitoring program that will intensively study water quality in siz creeks in the county. The program is designed to provide accurate water quality information with the precision that is required to resolve spatial and temporal variability in water quality parameters. 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.
