About the Data
3
Data SourceThe Hudson River Conditions Observing System (HRECOS) operates a number of hydrological and meteorological monitoring stations in and near the Hudson River. The monitoring stations collect continuous data every 15 minutes for many variables.
4
Data Time FrameHRECOS data collected from 8/25/2011 until 9/5/2011.
5
Data Collection LocationPort of Albany NY - 42.61954 N, 73.75890 W
The Albany HRECOS station is mounted on the concrete piling on the western shoreline of the Hudson River at the Port of Albany, just to the south of the Cargill Grainery. The channel depth at this location is 32 feet.

Norrie Point NY - 41.831876 N, -73.941606 W
Norrie Point Station is located at the headquarters of the Hudson River National Estuarine Research Reserve within the Margaret Lewis Norrie State Park, operated by the Taconic Region of New York State Office of Parks, Recreation, and Historic Preservation.

Piermont Pier NY - 41.043 N, 73.896 W
Piermont Station is located on Piermont Pier, which is owned and operated by the village of Piermont. ***The Piermont hydrological station was offline for repairs during Hurricane Irene so we only have data from the meteorological station (rainfall).

Dataset HeadingData Description

Date TimeDay and time of sampling (eastern time)
9
Rainfall daily accumulation The amount of rain (measured in inches) that cumulatively fell over a 24 hour-period. The data points you see here reflect the daily total up to that hour of the day. The count resets every day at 1:00 AM EST.
10
TurbidityAmount of suspended particulates in the water measured in nephelometric turbidity units (NTU). This helps us to note how cloudy the water was.
11
DepthA measure of water depth (measured in feet) above sensor, which is an indication of tide and rainfall.
12
Water temperatureWater temperature, measured in degrees Fahrenheit
13
DO (dissolved oxygen)The amount of oxygen dissolved in the water, measured in parts per million (ppm).
14
% DO (dissolved oxygen saturation)The amount of oxygen dissolved in the water compared to the amount it could hold when it is at equilibrium with the atmosphere. This is dependent on temperature. (On the last tab, %DO, this is HRECOS Data collected July 30-31 in 2011, 2012, 2016.)
