Project Description and Goals
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.
Project Methods
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.
