Summary
Abstract:
Research objectives Monthly Grab Monthly grab samples are collected to quantify the spatial and temporal variability of selected nutrients and plant pigments in the water column along a salinity gradient within the York River estuary system. Diel Sampling Program On a monthly basis, samples are collected at Taskinas Creek, a small tributary of the ... York River,
every two and one-half hours throughout a complete tidal cycle in order to quantify the
short-term temporal variability of selected nutrients and plant pigments in the water
column.

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character a) Goodwin Islands (Lat 37.21739; Long 76.3954) The Goodwin Islands component of the
CBNERRVA is located on the southern side of the mouth of the York River. The Goodwin Islands are
a 315 ha (777 acre) archipelago of salt-marsh islands surrounded by inter-tidal flats, extensive
submerged aquatic vegetation (SAV) beds (121 ha; 300 acres). Water circulation patterns around
the island are influenced by York River discharge and wind patterns of the Chesapeake Bay. Tides
at the Goodwin Islands are semi-diurnal and display an average range of 0.7 m (range: 0.4 - 1.1
m). Seasonal water quality conditions described here are from 1998 through 2003 (Spring:
March-May; Summer: June-August; Fall: September-November; Winter: December-February). Mean
seasonal water temperature ranged between 13.7-15.6 for spring, 25.7-27.2 for summer, 18.0-19.2
for fall, and 4.7-8.2 °C in winter. Mean seasonal salinity ranged between 13.9-23.0 for spring,
17.3-23.0 for summer, 20.4-24.0 for fall, and 18.4-23.3 ppt in winter. b) York River Bridge (Lat
37.24489; Long 76.50522) The Coleman Bridge station is located in the mid-channel approximately
9 km from the mouth of the York River estuary between Gloucester Point and Yorktown, Virginia.
The sampling station is located within the polyhaline region with a mean depth of 21 meters and
a tidal range of 0.75 meters. c) Catlett Islands (Lat 37.30000; Long 76.55000) The Catlett
Islands are located approximately 20 km from the mouth and on the North side of the York River
in Gloucester County, Virginia. Timberneck Creek flows into the York River on the eastern side
of the Catlett Islands and Cedarbush Creek enters the river on the western side. Poplar Creek
bisects the two large areas of the Catlett Islands. Catlett Islands encompass 280 ha (690acres)
and displays a ridge-and-swale geomorphology. The islands consist of multiple parallel ridges of
forested wetland hammocks, forested upland hammocks, emergent wetlands and tidal creeks
surrounded by shallow subtidal areas that once supported beds of submerged aquatic vegetation.
Water quality ranges listed here are based on weekly volunteer citizen water quality monitoring
has been ongoing since the incorporation of the site in 1990. Surface water temperatures range
from 5.4 °C to 27.4 °C. Salinity is indicative of mesohaline conditions, ranging from 14-18
ppt in the fall to 8.2-12 ppt in the spring. Dissolved oxygen concentration ranges from 4.2 to
14.0 mg/L. Tidal range is on the order of 0.75 meters. d) Claybank (Lat 37.34855; Long 76.61123)
The Claybank station is with a shallow (2m) littoral area approximated 300-400 meters
wide located within the mesohaline portion of the York River estuary approximately 26 km upriver
from the mouth of the estuary. The shoreline consists of a narrow fringe of salt marsh with some
areas armored with bulkhead or stone. Tidal range is on the order of 0.85 meters. This station
is located along the north shoreline of the estuary in an area that was vegetated with submersed
aquatic vegetation prior to 1972 but has remained unvegetated since that time. The sediment
consists of muddy sands. The sampling station is influenced by a secondary turbidity maximum
that moves back and forth in a region of about 20-40 km from the mouth of the York River
estuary. The site is exposed to strong winds from the northwest and re-suspension of sediment
during storm events can be high. Seasonal water quality conditions described here are from 2001
through 2003 (Spring: March-May; Summer: June-August; Fall: September-November; Winter:
December-February). Mean seasonal water temperature ranged between 14.0-16.2 for spring,
26.1-27.7 for summer, 17.5-19.4 for fall, and 4.9-8.0 °C in winter. Mean seasonal salinity
ranged between 15.7-20.3 for spring, 16.5-21.3 for summer, 13.2-21.6 for fall, and 14.3-20.0 ppt
in winter. e) Taskinas Creek (Lat 37.41497; Long 76.71441) Taskinas Creek Reserve encompasses
397 ha (980acres) and is located in York River State Park near the town of Croaker, in James
City County, Virginia. The small sub-estuary of the York River is located on the southern side
of the river, approximately 22 km upriver from VIMS and 37 km from the mouth of the York River.
The Taskinas Creek watershed is representative of an inner coastal plain rural watershed within
the southern Chesapeake Bay system. The watershed is dominated by forested and agricultural land
uses with an increasing residential land use component. The non-tidal portion of Taskinas Creek
contains feeder streams that drain oak-hickory forests, maple-gum-ash swamps and freshwater
marshes. Freshwater mixed wetlands are found in the upstream reaches of Taskinas Creek. Taskinas
Creek is roughly 2 meters deep and 20 meters wide towards the lower end of the creek. Mean tide
range is 0.85 m. Sub-tidal substrates are dominated by fine sediments. Seasonal water quality
conditions described here are from 1998 through 2003 (Spring: March-May; Summer: June-August;
Fall: September-November; Winter: December-February). Mean seasonal water temperature ranged
between 15.2-19.0 for spring, 26.8-28.2 for summer, 17.6-18.3 for fall, and 3.9-9.0 °C in
winter. Mean seasonal salinity ranged between 4.0-14.0 for spring, 7.0-18.2 for summer, 6.9-17.0
for fall, and 8.4-15.3 ppt in winter. Wildlife populations are known to influence
microbiological water quality in Taskinas Creek. f) Sweet Hall Marsh (Lat 37.57138; Long
76.88424) Sweet Hall Marsh is the most downriver extensive tidal freshwater marsh located in the
Pamunkey River, one of two major tributaries of the York River. The marsh is located
approximately 77 km upriver from the mouth of the York River estuary. This reserve area is 353
ha (871 acres) in area and includes 331 ha (818 acres) of emergent fresh-water marsh, 14 ha (35
acres) of permanently flooded broad-leaved forested wetlands and approximately 4 ha (9 acres) of
scrub-shrub. The marsh community is classified as freshwater mixed. Mean tidal range at Sweet
Hall Marsh is on the order of 0.9 m. Seasonal water quality conditions described here are from
2002 through 2003 (Spring: March-May; Summer: June-August; Fall: September-November; Winter:
December-February). Mean seasonal water temperature ranged between 14.7-16.7 for spring,
26.7-27.9 for summer, 19.1 (both years) for fall, and 4.7-6.3 °C in winter. Mean seasonal
salinity ranged between 0.1-3.4 for spring, 0.1-8.4 for summer, 0.4-8.4 for fall, and 0.3-3.2
ppt in winter.

in the NERRS System submit data that are censored at a lower detection rate limit, called the
Method Detection Limit or MDL. MDL's for specific parameters are listed in the
Laboratory Methods and Detection Limits Section (Section I, Part 12) of this document.
Concentrations that are less than this limit are denoted by a 9999 and comment coded
with a B in the variable code comment column. For example, the measured
concentration of NO23F was 0.0005 mg/l as N (MDL=0.0008), the reported value would be -9999 with
a B placed in the NO23F comment code column. Calculated parameters are
comment coded with a C and if any of the components used in the
calculation are below the MDL, the calculated variable is denoted by 9999 and also
comment coded with a B. If a calculated value is negative, the value is
reported as comment code N and a value of -9999. Suspect data is denoted
with a S in the variable code comment column. Nutrient and Plant Pigment
