Oceanographic data collected from station Passaic River, NJ by Hudson River Environmental Conditions Observing System (HRECOS) and assembled by Mid-Atlantic Regional Association Coastal Ocean Observing System (MARACOOS) in the Hudson River from 2014-03-13 to 2019-03-31 (NCEI Accession 0163414)

This dataset contains oceanographic data collected at Passaic River, NJ, a fixed station in the Hudson River. These sensors measure CONDUCTIVITY, DEPTH - OBSERVATION, DISSOLVED OXYGEN, LATITUDE, LONGITUDE, OXYGEN - PERCENT SATURATION, SALINITY, WATER TEMPERATURE, pH and turbidity at frequent intervals in the nearshore coastal ocean. Hudson River Environmental Conditions Observing System (HRECOS) collected the data and provided the data to MARACOOS, which assembles data from Hudson River Environmental Conditions Observing System (HRECOS) and other sub-regional coastal and ocean observing systems of the Mid-Atlantic Coastal United States, submitted the data to NCEI as part of the Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program. The data are made available in netCDF formatted files, which follow the Climate and Forecast metadata convention (CF) and the Attribute Convention for Data Discovery (ACDD). Each month, NCEI adds to this dataset the data collected during the previous month.

The hydrologic station is located at the north end of the PVSC dock on the Kearny Point Reach of the Passaic River, adjacent to 'USGS Tide Gage 01392650 Passaic River at PVSC at Newark NJ'. A YSI EXO2 water quality sonde measures dissolved oxygen, pH, specific conductance, salinity, turbidity, depth, and water temperature every 15 minutes. The sonde is housed in a locked 4” diameter PVSC pipe which is bolted to the concrete sea wall. The sonde sits on a bolt set across the bottom of the pipe, which is set approximately 1 meter above the bottom of the river. The bottom 2 feet of the pipe is perforated with numerous holes to allow free water flow past the sensors. Data is recorded by a CR200 datalogger and transmitted to the HRECOS database via a Raven XT cellular modem.
