ModMon Neuse River Estuary and Pamlico Sound Water Quality Monitoring from 1994-01-24 to 2022-01-22 (NCEI Accession 0294041)

The Neuse River Estuary Water Quality Dataset is a compilation of the biological, chemical and physical water quality data that was collected along the length of the Neuse River Estuary, North Carolina from January 24, 1994 to the present. The primary purpose of this dataset was to provide long-term environmental information to supplement experimental, process-based research, including the Atlantic Coast Environmental Indicators Consortium (ACE-INC) project as well as other laboratory studies. This dataset is composed of four spreadsheets (xlsx) containing regular water sampling and in situ measurements collected at fixed sampling stations in the Neuse River and Pamlico Sound. The data in the files titled "SECOORA_NRWQ..." and SECOORA_PSWQ..." contain water samples and in situ measurements collected at the surface (approximately 0.2 meters) and at the bottom of the water column (approximately 0.5 meters from the sediment layer). The data in the file titled "SECOORA_NR_YSI..." and "SECOORA_PS_YSI..." contain in situ measurements performed throughout the water column in 0.5 meter depth increments. Parameters measured include: temperature, salinity, specific conductivity, dissolved oxygen (DO), pH, chlorophyll fluorescence, photosynthetically active radiation (PAR), turbidity, barometric pressure, Secchi depth, colored dissolved organic matter (CDOM), particulate organic carbon (POC) and nitrogen (PN), dissolved organic and inorganic carbon, dissolved inorganic nutrient concentrations (nitrate/nitrite, ammonium, total dissolved nitrogen, phosphate and silicic acid), chlorophyll a, primary productivity and diagnostic phytoplankton pigment concentrations (chlorophylls and carotenoids). Calculated parameters include: diffuse light attenuation coefficient (Kd), carbon to nitrogen molar ratio (C:N), dissolved inorganic nitrogen (DIN; nitrate/nitrite plus ammonium), dissolved organic nitrogen (DON; total dissolved nitrogen minus dissolved inorganic nitrogen) and the nitrogen to phosphorus molar ratio (N:P).
