These stations monitor the river's water quality and upload the data onto the Internet, where anyone in the world with an Internet connection can check on the health of the estuary.
MERI now continually takes the river’s pulse year-round through these monitoring stations, located at four sites along the Hackensack.
MERI tracks dissolved oxygen, water turbidity (how cloudy the water is), temperature, salinity and acidity.
The data provide a fuller picture of the water conditions. High water temperatures, for example, affect dissolved-oxygen levels and can kill fish.
