The Wetlab

Oyster Reef Ecosystem exhibit tank at the Wetlab Estuarium entrance.

The River Project's marine biology field station, the Wetlab, is located on Pier 40 in Hudson River Park. The Wetlab features a 3,500-gallon flow through aquarium system that supplies brackish water pumped from the Hudson River Estuary into a collection of fish tanks. This Hudson River flow through system was originally designed by TRP staff on Pier 26 as the Estuarium. Due to constant inflow and outflow of river water, tanks in the Wetlab naturally experience the same variations in temperature, salinity, and other water quality conditions that occur in the harbor. Native fish and invertebrate species collected as part of TRP’s ongoing species monitoring efforts are temporarily kept in this aquarium system for research and education purposes, and released by the end of our active season. TRP uses the Wetlab to carry out a number of in-house research projects, including a 30-year fish ecology survey and the Citizens Water Quality Testing program. The Wetlab facilities are also available to visiting researchers, with River Project staff providing laboratory technician support.

Starting in late March through early November, the Wetlab is open to the public on Tuesdays and Thursdays from 2pm-5pm. The River Project also hosts field trips, professional development workshops, and internships based in the Wetlab throughout the open season. This summer, the Wetlab will be open on select Sundays, 12pm-4pm. For more information about our public hours and events, check out our calendar!
