IEC just deployed its first continuous monitoring sonde for readings in the New York/New Jersey Harbor! In conjunction with the New Jersey Department of Environmental Protection (NJDEP), four YSI EXO2 multiparameter sondes will be placed throughout the New York/New Jersey Harbor in order to provide continuous readings of water quality. The deployed sondes will remain in the water year-round when conditions allow and will measure temperature, conductivity, dissolved oxygen, pH, turbidity, and chlorophyll.

The 2024 LIS Hypoxia Season Summary, produced by the Connecticut Department of Energy and Environmental Protection (CTDEEP) using data collected in conjunction with IEC, is now available. 

IEC’s annual “State Summaries” are now published, providing an overview of the organization’s work and impact in the three states in its environmental district throughout the fiscal year 2023-2024. In addition to water quality programs, collaborative activities are shared, including workgroups and committees, public education and outreach.

Check out these summer 2024 time-lapse videos depicting dissolved oxygen levels in the western Long Island Sound! These visualizations were developed using surface (1 meter depth) and bottom (1 meter above sediment) dissolved oxygen measurements taken by IEC during our weekly water quality surveys in summer 2024. Low or depleted dissolved oxygen levels in a waterbody is referred to as hypoxia. Hypoxia can result in significant adverse effects on marine life and habitats, which need sufficient dissolved oxygen (>5.00mg/L) to survive and thrive.

You're invited! Join IEC, BioBAT Art Space to immerse yourself in the Water Stories exhibit, featuring a collaborative set of artworks based on IEC's monitoring created by artist Yoko Shimuzu.

Check out these time-lapse videos depicting dissolved oxygen levels in western Long Island Sound! These visualizations were developed using dissolved oxygen measurements taken by IEC during weekly #waterquality surveys in summer 2023. Discrete (individual) dissolved oxygen measurement were interpolated using GIS to estimate dissolved oxygen in areas surrounding the discrete measurements.  Dissolved oxygen maps from each weekly survey were then collated into these time-lapse videos.

Check out these time-lapse videos depicting the onset (and subsequent dissipation) of #hypoxia in western Long Island Sound! These visualizations were developed using dissolved oxygen measurements taken by IEC during weekly #waterquality surveys in summer 2022. Discrete (individual) dissolved oxygen measurement were interpolated using GIS to estimate dissolved oxygen in areas surrounding the discrete measurements. The dissolved oxygen maps from each weekly survey were then collated into these time-lapse videos.

It was a landmark day for IEC on Monday, October 24th, as we held a ribbon-cutting ceremony for our new laboratory and office headquarters, located at BioBAT, on the former Brooklyn Army Terminal complex on the Brooklyn Waterfront.

BioBAT, Inc. (www.biobat.nyc) and the Interstate Environmental Commission seek proposals from qualified general contractors to build and fit-out 2,800 square feet of BSL-2 laboratory and office space.  BioBAT, as landlord, and IEC, as tenant, are negotiating a lease on the second floor of BioBAT in Building A at the Brooklyn Army Terminal.

Key Dates:

On Tuesday, June 30th, IEC resumed monitoring surveys in Far Western Long Island Sound, after a two-month hiatus due to COVID-19. These surveys monitor dissolved oxygen, as well as parameters that may impact dissolved oxygen at 22 stations in support of the Long Island Sound Water Quality Monitoring Program.  IEC performs monitoring surveys weekly during the critical summer season, when hypoxia is most prevalent. Weekly surveys will continue through mid-September.
