Oceanographic data collected from station Pump Station 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 2012-07-19 to 2019-03-31 (NCEI Accession 0163411)

This dataset contains oceanographic data collected at Pump Station, a fixed station in the Hudson River. These sensors measure CONDUCTIVITY, DEPTH - OBSERVATION, DISSOLVED OXYGEN, LATITUDE, LONGITUDE, OXYGEN - PERCENT SATURATION, WATER LEVEL, WATER TEMPERATURE 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 intake for the pump station is located 91 meters from the main channel and is raised by a tripod approximately 3 meters from the river bottom (41.720993 N, 73.942569 W). Water depth is 18 meters at this location. Water is pumped from this location into the pump house where water quality sensors on a YSI 6600 sonde record the following parameters every 15 minutes: specific conductance, turbidity, and water temperature. A separate sensor at the southern edge of the Marist Boat dock (41.720585 N, 73.938794 W) records water elevation, which is converted from NGVD29 to NAVD88 in the HRECOS database. All data are recorded by a CR1000 datalogger and transmitted to the HRECOS database via cellular modem.
