Sediment and contaminant movement with the tides in the lower Hackensack River

In Estuaries, sediments and contaminants move around with the tide.  This study measures the suspended sediment and flow direction from the main channel of the river to the marsh platform and the other way around. To determine in which directions contaminants are moving, MRRI scientists installed an Argonaut-ADV instrument that measures water velocity and direction, and a time-integrated sediment trap that collects sediment during both the ebb and flood tide cycles. In the Meadowlands, the type and quantity of contaminants and their movement with the tides have implications for the long-term health and sustainability of marsh habitats.
