  • Dataset Abstract
    The Southeast Environmental Research Center at Florida International University operates a network of 331 fixed sampling sites distributed throughout the estuarine and coastal ecosystems of south Florida. The purpose of this network is to address concerns in regional water quality which cross and overlap separate political boundaries. Funding has come from different sources with individual programs being added as funding became available. Biscayne Bay, Florida Bay, Whitewater Bay, Ten Thousand Islands, Rookery Bay, Estero Bay, andPine Island Sound are sampled monthly while the Florida Keys National Marine Sanctuary (FKNMS) and the southwest shelf are sampled quarterly. Variables currently being measured include surface and bottom temperature, salinity, dissolved oxygen, nitrate, nitrite, ammonium, total nitrogen, total organic nitrogen, total phosphorus, soluble reactive phosphorus, total organic carbon, total silicate, chlorophyll a, alkaline phosphatase activity, turbidity, and light extinction. The purpose of this network is to address concerns in regional water quality which cross and overlap separate political boundaries. One of the products is a quasi-synoptic big picture of nutrient and phytoplankton biomass distributions over the South Florida Coastal Waters. The SERC network will, in time, provide us with the data necessary to determine whether conditions within the estuaries and sanctuary are improving or declining.

    Method Step

    Description
    Water samples were collected and analyzed by SERC personnel using standardmethodology outlined in the Quality Assurance Project Plan (QAPP) with prior approval from SFWMD and FDEP. Salinity and temperature (degrees C) were measured 10 cm below the surface and 10 cm above the bottom using a combination salinity-conductivity-temperature probe (Orion model 140). Surface and bottom dissolved oxygen (DO, mg l-1) was measured using an oxygen electrode (Orion model 840), corrected for both salinity and temperature. Duplicate, unfiltered water samples were collected from 10 cm below the surface using sample rinsed, 120 ml HDPE bottles and kept at ambient temperature in the dark during transport. Duplicate water samples for dissolved nutrient analysis were collected using sample rinsed 150 ml syringes. These samples were filtered by hand (25 mm glass fiber GF/F) into acetone-washed and sample rinsed 60 ml HDPE bottles, which were then capped and immediately placed on ice in the dark for transport. The wet filters, used for chlorophyll a analysis (CHLA), were placed in 2 ml plastic centrifuge tubes to which 1.5 ml of 90% acetone was added. They were then immediately capped and put into a dark bottle on ice for transport. Unfiltered water samples were analyzed for total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), alkaline phosphatase activity (APA), and turbidity (NTU). TOC was measured by direct injection onto hot platinum catalyst in a Shimadzu TOC-5000 after first acidifying to pH<2 and purging with CO2-free air. TN was measured using an ANTEK 7000N Nitrogen Analyzer using O2 as carrier gas instead of argon to promote complete recovery of the nitrogen in the water samples. TP was determined using a dry ashing, acid hydrolysis technique. The APA assay measures the activity of alkaline phosphatase, an enzyme used by bacteria to mineralize phosphate from organic compounds. The assay is performed by adding a knownconcentration of an organic phosphate compound (o-methylfluorescein phosphate) to an unfiltered water sample. Alkaline phosphatase in the water sample cleaves the phosphate, leaving o-methylfluorescein, a highly fluorescent compound. The fluorescence of initial and 2 hr incubations were measured using a Gilford Fluoro IV spectrofluorometer (excitation = 430 nm, emission = 507 nm) and subtracted to give APA (uM h-1). Turbidity was measured using an HF Scientific model DRT-15C turbidimeter and reported in NTU. Filtrates were analyzed for soluble reactive phosphorus (SRP), nitrate + nitrite (NOx), nitrite (NO2-), ammonium (NH4+), and silicate (Si(OH)4) by flow injection analysis (Alpkem model RFA 300). Filters for CHLA content (µg l-1) were allowed to extract for a minimum of 2 days at -20degrees C before analysis. Extracts were analyzed using a Gilford Fluoro IV Spectrofluorometer (excitation = 435 nm, emission = 667 nm) and compared to a standard curve of pure CHLA (Sigma). Some parameters were not measured directly, but were calculated by difference. Nitrate (NO3-) was calculated as NOX - NO2-. Dissolved inorganic nitrogen (DIN) was calculated as NOX + NH4+. Total organic nitrogen (TON) was defined as TN - DIN. Concentrations for all of these water quality variables are reported in units of milligrams per liter (mg l-1) or the equivalent parts per million (ppm), except where noted. All nutrient concentrations are based on the atomic weight of primary nutrient species (ppm-N, ppm-P, and ppm-C), not the molecular weight. All N:P ratios discussed are calculated on a molar basis.
