Elkhorn Slough (ELK) NERR Water Quality Metadata January - December 2001 Last updated February 4, 2003Entry ID: CDMO_elkwq01-12.01m
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 Measurements are taken every 30 minutes over a three to four week period at four sites in Elkhorn Slough. One site, South Marsh (SM), is in a relatively unimpacted side channel of the slough and the second, Azevedo Pond (AP), is in a pond that receives fertilizer and pesticide runoff from an adjoining strawberry field. The third site, North Marsh (NM), was added in April 1999 ... and is located in an area where there is both agricultural and non-agricultural runoff. The fourth site, Vierra Mouth, is located at the mouth of the slough and is used to identify oceanic influence. This site was added March 14, 2001 at 1300. The purpose of this research is to identify the base parameters for Elkhorn Slough by using South Marsh as the control site and the other three sites are impacted sites and monitored for possible future problems.
Associated researchers and projects Elkhorn Slough National Estuarine Research Reserve and the Elkhorn Slough Foundation have had an ongoing program to monitor estuarine water quality in the central Monterey Bay region since 1988. Currently, 24 stations are monitored monthly for temperature, salinity, dissolved oxygen, pH, turbidity, nitrate, ammonium and dissolved inorganic phosphate concentrations. Two of these stations on the Reserve are about 400 m from the SM site. Data collection began at these two stations in September 1989. A monthly monitoring station is also located at Azevedo Pond within 10 m of the YSI deployment. Monthly data from the Azevedo Pond are available from March 1992. The University of California Santa Cruz Agroecology Program has an ongoing project to examine the effects of agricultural production on an adjacent wetland. Matthew Werner, Marc Los Huertos, Felecia Rein, Sean Swezey, Mark Silberstein, Andrew De Vogelaere, Ron Tjeerdema have been the principal investigators.

Flores, Karen & Miller, Susan, undergraduates, CSUMB, monitor distribution and abundance of native and invasive crabs. Gaddam, Rani, benthic monitoring intern, ESNERR, develop and test benthic monitoring protocols for native and invasive crabs. Hagen, Joy, graduate student, UCSC, determine herbivory levels on mustards. Heiman, Kimberley, graduate student, MLML, investigate community effects of invasive invertebrate habitat structure. Kerr, Lisa, graduate student, MLML, seasonal patterns of reproductive endocrinology of leopard sharks. Kvitky, Alona; Karas, Brian, distinguish gender differences in round ray diet and dentition. Potts, Don; Siciliano, Daria; Jupiter, Stacy, professor & graduate students, UCSC, remote-sensing of vegetation and habitats with hyperspectral aerial imagery. Reis, Dawn Kathleen, researcher, demography of red-legged frog populations. Van Sommeran, Sean; Jakl, William, Van Sommeran, Sean; Jakl, William, monitor species diversity, abundance, and sex of elasmobranches. Villa, Elizabeth, undergraduate, CSUMB. determine reproductive phenology of chickadees. Zimmerman, Richard; Palacios, Sherry, researcher and graduate student, MLML, Zostera distribution and abundance and relation to CO2. Other remarks/notes Any time a reference is made to turbidity data being negative and/or zero, it was recorded as a negative in the raw data file and a zero in the edited data file due to the formatting of Excel. The technician edited none of these data points by hand nor did he/she delete any of them.
SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character Elkhorn Slough is located on the West Coast of the United States in Central California. It connects with the Pacific Ocean in central Monterey Bay near Moss Landing, California. The Slough drains 182 km2 and has most of the fresh water input from small creeks during the winter months. The watershed consists of a mixture of grazed, farmed, developed lands, and oak woodland and chaparral. There are four NERR sampling sites. The tidal range is approximately 6.5 ft., and salinity ranges between 29 and 34 part per thousand. VM (Vierra Mouth, Latitude = 36o48'39.96"; Longitude = 121o46'44.4") is approximately 4 meters at the entrance to slough, mostly muddy bottom with some clam and eel grass beds, and receives oceanic flushing as well as some inputs from Salinas River and Moro Cojo runoff. The YSI is located off the old concrete outflow of the now Duke Power outflow site. This site was added March 14, 2001 at 1300 SM (South Marsh, Latitude = 36o 49'04.72"; Longitude = 121o 44'21.95") is approximately 2.5 m deep, has a muddy bottom, is in a side channel of the slough and is relatively unimpacted by anthropogenic influences. The YSI is located on the side of a bank in one of the secondary slough channels. AP (Azevedo Pond, Latitude = 36o 50'44.41"; Longitude = 121o 45'13.50") is approximately 1 m deep, has a muddy bottom, and is in a pond that receives fertilizer and pesticide runoff from a strawberry field in year-round production. The YSI is located about 10m from a culvert connecting the pond to the slough. NM (North Marsh, Latitude = 36o 50'04.68", Longitude = 121o 44'18.19") is approximately 1 m deep, has a muddy bottom, is located in between South Marsh and Azevedo Pond. This site is impacted by both agricultural and urban runoff.
