Temp (f)
TemperatureHudson River water temperature changes seasonally. Surface water temperature can change on small scales in the river reflecting natural and human influences. |

Salinity
SalinityEstuaries like the Hudson are where freshwaters in rivers meet the sea. Salinity tells us about the relative contribution of fresh and salt water within a particular region of the estuary. |
[i]
Chlorophyll
ChlorophyllA measure of the amount of microscopic algae present in the water. High chlorophyll counts can mean high levels of the nutrients phosphorus and nitrogen, and the threat, or presence, of algae blooms. |
[i]
Turbidity
TurbidityTurbidity is a measure of the amount of fine particles suspended in the water. As turbidity rises, light penetration, a key factor for aquatic plants and algae, diminishes. |
[i]
Oxygen
OxygenOxygen concentrations in the water are closely connected to biological activities. Surface waters are typically in equilibrium with the atmosphere such that the oxygen concentration near the surface is close to fully saturated (100%). |

(in inches)
Enterococcus is an EPA-approved fecal contamination indicator.
Samples taken by Riverkeeper, Lamont-Doherty Earth Observatory and CUNY Queens College staff, and processed on the Riverkeeper vessel, according to the 2014 Quality Assurance Project Plan.
Rainfall data comes from wunderground.com. Wet weather is a common trigger of fecal contamination.
