Hudson River (HUD) NERR Water Quality Metadata (April - Dec. 2003) Latest Update: April 12, 2004Entry ID: CDMO_hudwq04-12.03m
Abstract: Water quality monitoring is conducted at 26 National Estuarine Research Reserves (NERR) at four locations within or adjacent to the reserve. The following parameters are collected at least every 30 minutes: water temperature, specific conductivity, salinity, percent saturation, dissolved oxygen concentration, water depth, pH and turbidity. All water quality data loggers will be deployed from a known depth from the bottom at each site.
Purpose: Research objectives The objective of this study is to monitor surface water quality at the Tivoli Bays component of the Hudson River National Estuarine Research Reserve (NERR). Two tidal freshwater wetlands, Tivoli North Bay and Tivoli South Bay, and their primary upland tributaries, Stony Creek and Saw Kill Creek respectively, are monitored using four dataloggers (YSI 6600 sondes). In Tivoli ... North Bay and Tivoli South Bay the dataloggers monitor the ebbing and flooding Hudson River water. In Stony Creek and Saw Kill Creek, the dataloggers are deployed above the area of tidal influence and monitor the quality of water entering the Tivoli Bays via stream flow. Thus, the relative importance of stream flow and tidal exchange and the potential impacts of intertidal areas on the water quality of the Tivoli Bays can be determined. Monitoring the water quality of the tributaries is important because it has previously been determined that urban and residential land use practices are markedly influencing the water chemistry of the tributaries, especially Saw Kill Creek. Since residential coverage continues to increase, we hope that the intensive monitoring of the surface waters in these watersheds will identify trends associated with this rapid development. Examining the influence of tidal exchange allows identification of long-term trends in the water quality of the Hudson River Estuary at this location and the potential inputs to the Estuary from the Tivoli Bays. Finally, the influence of intertidal areas on water quality within the Tivoli Bays is interesting because of the potential impacts of both floating and emergent invasive plant species present in this system.
Associated researchers and projects As part of the Hudson River NERR water quality monitoring project, physical and chemical constituents of the tributary waters discharging into HUDNERR marshes and marsh waters are measured monthly during ebb tides. Measurements include dissolved oxygen, seston, alkalinity, pH, temperature, salinity, conductivity and concentrations of ammonium, nitrate, phosphate, sulfate and chloride. Associated researchers working at the Tivoli Bays component site include scientists from the Institute of Ecosystem Studies in Millbrook, NY, Yale School of Forestry and Environmental Studies in New Haven, CT, and Rensselaer Polytechnic Institute in Troy, NY. Other remarks/notes A reference to negative and/or zero depth or depth readings flagged as outliers indicates that depth was recorded as a negative value in the raw data file and as zero in the edited data file due to the formatting of Excel. The technician edited none of these data points by hand nor did the technician delete any of them. If the post-deployment dissolved oxygen readings were out of the specification range (98%-102%), the data were carefully examined for obvious shifts in dissolved oxygen readings during deployment and readings at the end of deployment were checked against readings from the newly calibrated replacement sonde. If there were no obvious discontinuities and the probe was functioning adequately, data are not considered suspect and the post-deployment readings were not mentioned in the Data anomalies section (Section 11) of the metadata.
SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character The Hudson River National Estuarine Research Reserve (HUDNERR) is a multi- component site totaling approximately 5,000 acres. Each component of the reserve is referenced by River Mile (RM) of the Hudson River in New York State proceeding north from the southern tip of Manhattan (RM 0). The reserve includes the following four component sites: Piermont Marsh, Rockland County (RM 24)(41o02'30"N 73o54'15"W), Iona Island, Rockland County (RM 45)(41o18'15"N 73o58'45"W), Tivoli Bays, Dutchess County (RM 98)(42o02'15"N 73o55'10"W), and Stockport Flats, Columbia County (RM 124)(42o02'30"N 73o46'00"W). The four component sites include open water, tidal wetland, and adjacent upland buffer habitats and are representative of the diverse plant and animal communities that occupy the salinity gradient within the Hudson River Estuary. Development within the watersheds of the four component sites ranges from predominantly urban/suburban to forested/agricultural. The highlighted component for this study is the Tivoli Bays in Annandale, NY. This component includes four monitored sites: Tivoli South Bay, Tivoli North Bay, Saw Kill Creek and Stony Creek. All four monitored sites are freshwater (0.0 ppt salinity). Tivoli South Bay (latitude 42° 01' 37.336" N, longitude 73° 55' 33.445" W) is a tidal freshwater wetland with intertidal mudflats exposed at low tide. During the growing season (June ? September), the subtidal area of Tivoli South Bay is dominated by the invasive floating macrophyte Trapa natans. Tivoli South Bay has a tidal range of 1.19 meters and a soft, silt/clay bottom type. The depth at the sampling location ranges from 0.5 to 2.5 meters. The non-tidal freshwater input to Tivoli South Bay includes that of a large upland tributary and a few small perennial streams. Tivoli North Bay (latitude 42° 02' 11.56464" N, longitude 73° 55' 31.16645" W) is a freshwater tidal marsh with emergent marsh vegetation dominated by the cattail Typha angustifolia. Tivoli North Bay has a tidal range of 1.19 meters, a soft, silt/clay bottom type, and a depth range from 0.5 to 3.0 meters at the sampling location. The non-tidal freshwater input to Tivoli North Bay includes that of a large upland tributary and a few small perennial streams. Saw Kill Creek (latitude 42° 01' 01.543" N, longitude 73° 54' 53.589" W) is the main tributary flowing into Tivoli South Bay. The Saw Kill Creek watershed is 26.6 square miles and land use within the watershed includes forested (51.1%), agricultural (25.8%), and urban (16.5%) areas. Saw Kill Creek is non-tidal and freshwater input to this tributary consists of smaller creeks in the watershed. At the sampling location Saw Kill Creek has a depth range of 0.5 to 2.0 meters, a discharge range of 2x10-5 to 1.2 m3/sec, and a rocky bottom type. Stony Creek (latitude 42° 02' 45.556" N, longitude 73° 54' 40.237" W) is the main tributary flowing into Tivoli North Bay. The Stony Creek watershed is approximately 23 square miles and is dominated by agricultural land use. Like Saw Kill Creek, Stony Creek is non-tidal and freshwater input is via smaller creeks in the watershed. Characteristics of Stony Creek at the sampling location include a solid rock bottom and a depth range of 0.5 to 1.5 meters. Stony Creek discharge is currently being determined. The entire Hudson River system south of the Troy Dam is affected by polychlorinated biphenyls (PCBs), and Tivoli North and South Bays have low sedimentary concentrations of PCBs. Nutrient inputs to the Tivoli Bays via the non-tidal tributaries are the main concern in terms of pollutants. High concentrations of nitrate and phosphate have previously been documented in both Saw Kill Creek and Stony Creek. Saw Kill Creek appears to be strongly influenced by residential land use practices. This highlights the importance of continued monitoring and identification of non-point sources of pollution at these sites.
