Last Saturday, over 2,000 visitors streamed through the welcome tent and onto the Lamont-Doherty Earth Observatory campus for the 2024 edition of Open House—a once-a-year tradition that stretches back decades. This year also marks the 75th anniversary of Lamont, and so guests were treated to a wide variety of installations, experiments and lectures, including (but hardly limited to) a giant inflatable JOIDES Resolution, an augmented reality sandbox, VR games and a “warming stripe” installation, and some classics like bathtub science, exploding volcanoes, art, sticky glacier goo, rocks from space, and lectures on everything from seafloor mapping to nanoplastics, earthquakes to black holes, and so much more!

What a blast! These eruptions mimic those of Plinian volcanoes, using ping pong balls and liquid nitrogen.
You can’t buy this on Amazon: Nick Frearson of Lamont’s Polar Geophysics group discusses his housemadeIcePod, which takes detailed measurements of polar ice.

The cores contain layers of sediments deposited on the bottom of the ocean over millions of years. They are loaned to scientists worldwide to learn more about Earth’s climate history.

Lamont geophysicist Marc Spiegelman demonstrates how to make “oobleck” goo out of cornstarch and water, then shows how the substance is a great example of rheology—or how liquids, and solids, behave under pressure.

Weather in a tank: a rotating tank experiment that demonstrates the two key ingredients for the generation of weather systems atmosphere: rotation and differential heating. It demonstrates the process of baroclinic instability.

Atlantic sturgeon are migratory and spend six years of their juvenile life in Haverstraw Bay—our special section of the Hudson.

Happy 75th, Lamont! See you next year.
