Delaware (DEL) National Estuarine Research Reserve Metadata Version 4.0 (January-December 2003) Latest Revision: June 22, 2004

Entry ID: CDMO_delwq01-12.03m

Summary

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 principal objective of this study is to record long-term water quality data for Delaware Bay in order to observe any physical changes or trends in water quality over time. The four sites chosen for monitoring will assist in understanding the impacts of both urban and agricultural impacts on the respective watersheds. Scotton Landing, Lebanon Landing, and Division Street are ... located within the St. Jones River watershed, while the Blackbird Landing component is located in the Blackbird Creek watershed. The St. Jones River is impacted by urbanization upstream and extensive agricultural activity throughout the basin. The Blackbird Creek is one of the least impacted riverine systems in Delaware, although current development pressures that exist are increasing. Measurements are taken every 30 minutes over two week collecting periods at the Scotton Landing (SL), Blackbird Landing (BL), Lebanon Landing (LL), and Division Street (DS) sites.

Associated researchers and projects An extensive stormwater sampling and hydrodynamic modeling project is underway in the upper reaches of the St. Jones River Basin. This project includes flow weighted stormwater sampling to quantify pollutant loads from each of the major land uses found in the Basin. An additional stormwater sampling program is underway to analyze the impact of agricultural BMP's at sites in the Blackbird Creek Watershed, St. Jones River Watershed. A joint effort underway through NOAA's Center for Coastal Ecosystem Health and the DNERR characterization studies will initiate detailed monthly water quality sampling at three sites in each river over a two year period and will quantify the phytoplankton community with collections from the same sites. This project was scheduled to be initiated in February 1995.(See Section I.1. for research contacts.) II. Physical Structure Descriptors Other remarks/notes a) D.O probe warm up times were discussed at the 2002 NERR Technician Training Session. It was agreed that the entire system would employ a 60 second warm up time for the DO sensor. Sonde start times are set 1 minute prior to the desired reading time to compensate for the 60 second warm up period. Warm up times were changed as follows: Scotton Landing (deployment on February 21, 2002), Lebanon Landing (deployment on February 01, 2002), Division Street (deployment on January 31, 2002), Blackbird Landing (deployment on February 06, 2002). Autosleep functions were also checked on these dates and turned on wherever necessary. b) A new model 6136 turbidity probe was introduced in 2002 by YSI. This new probe replaced the old 6026 model. The dates of change for each site were as follows: Scotton Landing (deployment on March 12, 2002), Lebanon Landing (deployment on March 12, 2002), Division Street (deployment on April 03, 2002), Blackbird Landing (deployment on March 06, 2002). Model 6026 probes acted as stand ins due to 6136 calibration difficulties/probe failure at the following sites at these date time ranges: c) Calibration procedures changed with the introduction of the new turbidity probe model. The turbidity probe are now 3 inches from calibration fluid cup bottom. The calibration fluid cup always sits directly on a black surface (prior procedure used cup suspended over black surface). d) YSI introduced a new sonde guard with the new turbidity probes. The new guard measures 8 ?" and replaced the old 6 ?" guard. Please note the 2" difference between the new and old guards in regards to depth data when comparing current data with data prior to dates in Section 14, part b). Guard change dates are synonymous with turbidity probe model change dates listed in section 14, part b) of this document. e) Hurricane Isabel hit Delaware during the period of September 18-19, 2003. f) The DNERR commenced testing of the flat sensor pH probe at the Scotton Landing site on October 2, 2003. The purpose of this probe alteration is to test the effectiveness of the flat sensor probe when used in conjunction with a series 6600 non-EDS data sonde. g) On November 25, 2003 the DNERR began using YSI 6073G brand turbidity standard for turbidity probe calibration and abandoned the previously used APS Analytical Standards brand.

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character The Delaware National Estuarine Research Reserve is comprised of two component sites, the St. Jones River and Blackbird Creek components. Both components are located along the Delaware Bay Coast. The St. Jones River Component is located in central Kent County Delaware, east of the state capital city, Dover. The Blackbird Creek component is located in the unincorporated area of Southern New Castle County. There are four sampling sites, three located in the St. Jones component and one in the Blackbird Creek component. 1) Scotton Landing ? is located in the Lower St. Jones River at the Scotton Landing Public Fishing Pier, slightly upstream of Delaware Route 113. The river is 22.3 km long (mainstream linear dimension), has an average depth of 4m MHW and the width is 50 m. At the sampling site, the depth is 3.2 m MHW and the width is 40 m. The sediment is clayey silt with no bottom vegetation. The watershed-draining site is 19778 ha. The site is influenced by freshwater runoff from the relatively urbanized area upstream. Pollutants in the area include PCB's, PAH's, and pesticides. Salinity ranges from 1- 30 ppt. Tidal Range: Spring Mean (m) ? 1.26 Neap Mean (m) ? 1.13 Position: Latitude 39 degree 05' 05.9160" N Longitude 75 degree 27' 38.1049" W 2) Blackbird Landing - is located in the upper Blackbird Creek at Blackbird Landing Road. The creek is 25.8 km long (mainstream linear dimension), has an average depth of 3 m MHW, and an average width of 90 m. At the sampling site, the depth is 1.8 m MHW and width is 110 m. The sediment is silty clay with no bottom vegetation. The watershed draining site is 4694 ha. The site is influenced by freshwater runoff from unimpacted forested areas intermixed with agricultural land uses and a small amount of low-density development. There is very little pollutant presence in the area. Salinity ranges from 0-9 ppt. Tidal Range: Spring Mean (m) ? 1.12 Neap Mean (m) ? 1.13 Position: Latitude 39 degree 23' 19.5196" N Longitude 75 degree 38' 09.5882" W 3) Lebanon Landing- is located in the mid portion of the St. Jones River at the Lebanon Landing Public Fishing Pier, farther upstream from the Scotton Landing monitoring site. The St. Jones River is 22.3 km long (mainstream linear dimension), has an average depth of 4m MHW and the width is 50 m. At the sampling site, the depth is 3.0 m MHW and the width is 28 m. The sediment is clayey silt with no bottom vegetation. The watershed-draining site is 19778 ha. The site is influenced by freshwater runoff from the relatively urbanized area upstream. Pollutants in the area include PCB's, PAH's, and pesticides. Salinity ranges from 0 to 28 ppt. Tidal Range: Spring Mean (m) ? 0.855 Neap Mean (m) ? 0.671 Position: Latitude 39 degree 06' 51.8" N Longitude 75 degree 29' 57.1" W 4) Division Street- is located in the upper portion of the St. Jones River near the USGS station on Division Street. The site is influenced by runoff from the urbanized surroundings. The St. Jones River is 22.3 km long (mainstream linear dimension), has an average depth of 4m MHW and the width is 50 m. At the sampling site, the depth is 0.6m MHW and the width is 26 m. The sediment is clayey silt with no bottom vegetation. The site is fresh water and is influenced by urban freshwater runoff. The watershed draining site is 4694 ha. Pollutants in the area include PCB's, PAH's, and pesticides. Salinity Range: Fresh water (0.1 ppt.) Tidal Range: Not Applicable, freshwater Position: Latitude 39 degree 09' 49.4" N Longitude 75 degree 31' 08.7" W
