The water quality sensor at the Barge Marina was replaced with a state-of-the-art continuous water quality sensor. The sensor is a new generation YSI multiparameter EXO3 sond for estuarine applications. This probe allows us to supplement the seasonal and expensive grab samples and observe temporal details in the water quality of the lower Hackensack. Salinity, conductivity, dissolved oxygen temperature, turbidity, and pH are reported every 10 minutes. This new sond is designed with tough materials and new antifouling technology for extended deployment. Real-time measurements can be accessed from our top menu by clicking on Environmental Monitoring Data under the Scientific Data submenu.
