Lamont-Doherty Earth Observatory History on the Hudson

Lamont-Doherty Earth Observatory (LDEO) has a long history at Piermont and a strong connection to the Hudson. LDEO’s Hudson history begins in 1953 with the purchase of R/V Vema, our first marine research vessel, that was docked at Piermont Pier.

Piermont History on the Hudson

There is a long and rich history of Piermont; a history that is strongly connected to the Hudson River.

Wide Bays of the Hudson

The wide bays of the Hudson is comprised of Tappan Zee and Haverstraw Bay. This is the widest part of the Hudson with Haverstraw Bay extending about 3 miles wide. The characteristics of the wide bays section (i.e. wide, shallow, brackish) is critically important because it serves as a unique habitat and essential nursery area for many fish species. In fact, Haverstraw Bay is identified by the NYS as the highest ranked ‘Significant Coastal Fish and Wildlife Habitat’ in the Hudson. The Hudson River Field Station is located at the end of Piermont Pier in this wide bays section.

Biology of the Hudson

The Hudson River is full of life! We use a seine net to catch, identify, and record the fish species that we catch to build a stronger understanding of the species that reside in our section of the Hudson.

Iconic Fish of the Hudson

We have caught and identified 235 different fish species in the Hudson River estuary as of 2021, and we are frequently uncovering new species with regular sampling. However, there are three fishes that are iconic to the Hudson River: striped bass, Atlantic sturgeon, and shortnose sturgeon.

UPDATE: We are thrilled to be able to showcase this beautiful Model Atlantic Sturgeon to educate students and the pubic about the unique creatures that call the Hudson their home! 

Chemistry of the Hudson

The water chemistry of the Hudson is very dynamic. Piermont’s Hudson River Environmental Conditions Observing System (HRECOS) is a real time monitoring station continuously recorded a suite of water chemistry and weather parameters ever 15 minutes with our station operating year-round. Our station is one of many that are are geographically distributed along the Hudson and Mohawk Rivers.

The Hudson’s Invisible World

The Hudson has a whole microscopic world that cannot be seen by the naked eye! Microscopes help us study the microplastics, zooplankton, and phytoplankton that exist in the Hudson River.

The Dinosaur Fish

Atlantic sturgeon are prehistoric giants that have been around for the past 120 million years. During this video, you will learn about Atlantic sturgeon anatomy and life history, the dangers that threaten their population, and the research and management efforts being done to protect them!

Changing Waters- Haverstraw Bay

The waters of the Hudson River are changing due to climate change. Sea level rise, rising temperature, and increased precipitation drive ecological, economic, and social Hudson impacts. For example, the waters of the Hudson have increased 1.7C in the last 70 years, and these rising temperatures impact water chemistry, fish migration, health, and reproductive success.
