Program Info

Continuous water quality data are collected at four water quality stations (Station ID's: gtmpiwq, gtmsswq, gtmfmwq, gtmpcwq) located within the Guana Tolomato Matanzas NERR in 15-minute intervals for eight parameters using protocols established by the National Estuarine Research Reserve's System-Wide Monitoring Program. (SWMP). Continuous WQ data, protocols, and metadata can be downloaded at: .
water temperature (°C), specific conductivity (mS/cm), salinity (psu), dissolved oxygen (%), dissolved oxygen (mg/L), depth (m), pH and turbidity (NTU/FNU), Chlorophyll a (µg/L), Uncorrected Chlorophyll a (µg/L), TN (mg/L), NO23 (mg/L), NH4 (mg/L), NO2 (mg/L), NO3 (mg/L), TKN (mg/L), DIN (mg/L), TON (mg/L), DOC (mg/L), fecal coliform (cfu), TP (mg/L), PO4 (mg/L), TSS (mg/L), secchi (m), color (pcu), Kd (m-1), Irradiance (µmole photons/m2/s, discrete - water temperature (°C), discrete - salinity (psu), discrete - dissolved oxygen (mg/L), discrete - pH
Several sites were also sampled by NEAP (Program 5016): GTMPINUT, GTMSSNUT, GTMFMNUT, and GTMPCNUT. NEAP samples were collected at surface water depth, while GTM samples were collected at one meter off bottom.
To measure changes in estuarine waters that help provide a better understanding of how human activities and natural events can affect coastal resources and to provide valuable data on the short-term variability and long-term changes in estuaries to researchers, natural resource managers and other coastal decision-makers.
