Guana Tolomato Matanzas (GTM) National Estuarine Research Reserve Nutrient Metadata Report January - December 2004 Latest Update: August 29, 2005Entry ID: CDMO_gtmnut01-12.04m
Abstract: Nutrient monitoring is conducted at 26 National Estuarine Research Reserves (NERR) from four locations within or adjacent to the reserve on a monthly basis of the following parameters: orthophosphate, ammonium, nitrite, nitrate, and chlorophyll a. Note: Reserves may collect additional parameters which are available by searching the Yearly Files directory.
Purpose: Research objectives The System-wide Monitoring Program (SWMP) water quality initiative began within the GTMNERR in 2001. There are presently four permanent stations at which YSI 6600 EDS datasondes have been deployed for continuously monitoring a suite of selected abiotic parameters at 30 min intervals. The positions of these stations allow for comparisons between relatively pristine versus more ... urbanized drainage basins as well as higher versus lower salinity regions of the estuary (see “Station Descriptions” under “Site Location and Character”). Nutrient analyses are performed on water samples collected monthly at each of these sites. The objective of this effort is to quantify the spatial/temporal variability and trends, both seasonally and as a function of tidal forcing, of selected nutrient parameters within the Reserve and to explore how these are related to concurrently generated sonde and meteorological data. a) Monthly grab – The principal objective of the monthly grab sampling is to determine spatial and temporal differences in water quality in four ecologically distinct regions of the GTMNERR. b) Diel sampling program – The principal objective of the diel sampling is to determine the impact of tidal water exchange on water quality.
Associated researchers and projects Phytoplankton analyses - Aliquots of the monthly grab samples collected for nutrient analyses at the four principal GTMNERR datasonde stations were separately preserved for subsequent plankton analyses. Phytoplankton was examined using the Utermohl settling method (Utermohl 1958) and an inverted microscope. Representative digital images of dominant phytoplankton were recorded for each sampling site on a monthly basis and archived to permit subsequent evaluations of blooms for potentially harmful species. These data are archived at the GTMNERR. Complementary research - The GTMNERR nutrient monitoring program is part of a broader long-term effort by Dr. Phlips to define the structure and function of coastal marine ecosystems in Florida, including their watersheds. A central goal of this work is to provide the information needed to help assess the integrity and sustainability of Florida’s coastal marine resources. Within the lagoonal ecosystems of the east coast of Florida that include the GTMNERR, Dr. Phlips has several ongoing research projects that complement the monitoring program, including: (1) In 1997 a study of the plankton ecology of the Indian River Lagoon was initiated and continues through the current year. This project, funded by the St. Johns River Water Management District, includes the description of phytoplankton community structure and physical-chemical characteristics of the water column. In 1999 aspects of the study (primarily phytoplankton community structure) were extended to include parts of the intra-coastal waterway from Titusville to St. Augustine. (2) In another complementary study, Dr. Phlips is engaged in a long-term study of the impact of eutrophication on the ecology of the St. Johns River and estuary. The focus of this work, funded by the St. Johns River Water Management District, is water quality and the plankton community. The St. Johns study was initiated in 1993 and continues to this date. (3) In 2000, Dr. Phlips was awarded two four-year research grants from the USDA to investigate the impact of coastal eutrophication on the productivity and health of clam and oyster populations along the east and west coasts of Florida, including the area of the GTMNERR.

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character The GTMNERR (North section [NW and SE corners]: 30.1632Âº N, 81.3447Âº W and 29.9698Âº N, 81.2488Âº W; South section: 29.8295Âº N, 81.3294Âº W and 29.6017Âº N, 81.1936Âº W), located in the Florida Upper East Coast Drainage Basin, includes over 60,000 acres (24,281 hectares) of publicly owned forested uplands, tidal wetlands, estuarine lagoons and offshore seas. Geographically separated by the greater St. Augustine area, the Reserve is associated with the riverine systems of the Tolomato and Guana River estuaries to the north and the Matanzas River estuary to the south. The Tolomato River Basin is about 18 miles (29 km) in length with a drainage area of approximately 53,802 acres (21,773 hectares); it converges with the Matanzas River and Salt Run from the south before flowing into the Atlantic Ocean at the St. Augustine Inlet. The headwaters of the Guana River originate in the Diego Plains drainage area in Ponte Vedra Beach. This drainage basin encompasses approximately 7,800 acres (3,157 hectares). The Guana River runs parallel to the Tolomato on the seaward side, with the two lagoons joining 7 miles (11.3 km) north of the St. Augustine Inlet. The Matanzas River estuary is approximately 20 miles (32 km) in length and extends 8 miles (13 km) south of the Matanzas Inlet. The Matanzas River sub-basin has a drainage area of approximately 103,615 acres (41,931 hectares) and is bounded to the west by the Atlantic Coastal Ridge, which separates it from the lower St. Johns River basin. Both the St. Augustine and Matanzas Inlets provide oceanic exchange to the system. The Matanzas Inlet, one of the last “natural” inlets on Florida’s east coast, has been unimproved and is suitable only for small watercraft. The natural hydrology of the Guana Tolomato Matanzas system has been somewhat altered by water control structures, including dikes, inland wells, drainage ditches and a dam across a portion of the Guana River. In addition, the Intracoastal Waterway traverses both the Tolomato and Matanzas estuaries. The climate of northeast Florida is classified as humid subtropical and is characteristic of the Gulf and Atlantic coastal plain of the Southeastern United States. The average annual rainfall is approximately 52 inches (132 cm) per year, with the wet season extending from June through September. Seasonal variation in temperature within the Reserve follows that of rainfall with a summer period of high temperatures between June and September and a cooler period extending from December through March. The annual mean air temperature within the Reserve is approximately 21(C. Station descriptions: The Pine Island (gtmpinut) station is at Channel Marker 25 (30( 03.05Â´N; 81( 22.05Â´W) in the Tolomato River. This site is located within the Guana River Marsh Aquatic Preserve in the northern section of the GTMNERR. Channel Marker 25 is adjacent to Pine Island near the mouth of Deep Creek, which provides freshwater drainage from silviculture-dominated uplands in the northwestern portion of the Tolomato River Basin. The average depth at this site is approximately 3.8 m with a tidal range of about 1.6 m; the bottom type is muddy sand. Salinity ranged from 5.5 to 37.8 ppt during 2004. The Fort Matanzas (gtmfmnut) site (in the southern section of the GTMNERR) is located at Channel Marker 75 (29( 44.22Â´N; 81( 14.76Â´W) in the Matanzas River. This site is approximately 4 km north of the Matanzas Inlet and near a shoreline on Anastasia Island that is undergoing residential development. The average depth at this site is approximately 3.6 m with a tidal range of about 1.4 m; the bottom type is muddy sand. The salinity ranged from 7.7 to 37.5 ppt during 2004. Both the FM and PI stations are situated within Class II Shellfish Harvesting Waters. The San Sebastian (gtmssnut) station is at Channel Marker 1 (29( 52.10Â´N; 81( 18.28Â´W) located at the confluence of the San Sebastian and Matanzas Rivers, approximately 4 km south of the St. Augustine Inlet. The San Sebastian River drains an urbanized watershed in the western portion of St. Augustine; it is characterized by both residential and commercial development including five marinas. The average depth at this site is approximately 4.4 m with a tidal range of about 1.7 m; the bottom type is muddy sand. The salinity range during 2004 was from 14.4 to 36.9 ppt. The Pellicer Creek (gtmpcnut) station (29( 40.15Â´N; 81( 15.37Â´W) is at the end of a recreational dock in Faver Dykes State Park located within the Pellicer Creek Aquatic Preserve in the southern section of the GTM Reserve. Pellicer Creek is tidal and bordered for much of its length by publicly-owned conservation lands. The average depth at this site is approximately 2.3 m with a tidal range of about 0.6 m; the bottom type is muddy sand. The salinity ranged from nearly 0.1 to 32.9 ppt during 2004.

Standard Methods for the Examination of Water and Wastewater, 20th Edition. United Book Press, Inc. Baltimore, Maryland. MDL will change with the background levels of samples; therefore, there is no constant MDL. Reporting of Missing Data and Data with Concentrations Lower than Method Detection Limits Nutrient/Chla comment codes and definitions are provided in the following table. Missing data are denoted by a blank cell “ “ and comment coded with an “M”. Laboratories in the NERRS System submit data that are censored at a lower detection rate limit, called the Method Detection Limit or MDL. MDLs 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 the limit are denoted by a –9999 and comment coded with a “B” in the variable code comment 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 a –9999. Comment code Definition A Value above upper limit of method detection B Value below method detection limit C Calculated value D Data deleted or calculated value could not be determined due to deleted data, see metadata for details H Sample held beyond specified holding time K Check metadata for further details M Data missing, sample never collected or calculated value could not be determined due to missing data N Negative calculated value P Significant precipitation (reserve defined, see metadata for further details) U Lab analysis from unpreserved sample S Data suspect, see metadata for further details QA/QC Programs The QA/QC procedures are as prescribed in the Laboratory’s QA/QC plan. The plan is approved by the Florida Department of Health/DEP and is subject to Reference Material Checks, as well as periodic site inspections. a) Precision – i) Field variability: Two successive grab samples are collected for each monthly sampling event. Collections include field blanks for every 10 samples. ii) Laboratory variability: Field blanks are run for replicate samples (every 10 samples) and sample spikes. Precision is measured by %RSD (percent relative standard deviation) and is calculated from the standard deviation and mean of seven repeat measurements. %RSD is one hundred times the standard deviation divided by the mean of the measurements. iii) Inter-organizational splits: None. b) Accuracy - i) Sample spikes: Nutrient spikes are included in standard curve procedures associated with each analytical series run. ii) Standard reference material analysis: Standard reference materials are used for routine evaluation of accuracy. Field blanks are included in all runs. The Florida Department of Health certification process also includes ‘Blind Tests’ of accuracy on an annual basis. Accuracy is measured by Relative Percent Difference (RPD). It is calculated by multiplying the difference between two determinations of the same sample by two, dividing that result by the sum of the same values, and multiplying by 100 [RPD= 2((A-B)/(A+B)) X 100]. iii) Cross calibration exercises: None.
