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.

We’re in! Yes, IEC has finally taken the plunge into social media and we are not turning back! Please follow us, share and like our posts to spread the word and get updates on IEC’s work and the work of our partners in the shared waters of New York, New Jersey and Connecticut.

Thanks to the partnership of the Interstate Environmental Commission (IEC) and other partner agencies and organizations, a coordinated volunteer pathogen monitoring effort in the shared marine waters of the estuary and the Interstate Environmental District (IED) is now underway.  The combination of IEC’s laboratory space, QA/QC support oversight, and field equipment and the work of the 

IEC and CTDEEP are pleased to release the 2018 Long Island Sound Hypoxia Season Review.

The report focuses on CT DEEP’s and IEC’s 2018 in situ monitoring parameters and includes:
