Earth Sciences

Ben Holtzman and the Seismic Sound Lab take viewers on an entirely new sensory experience to see, hear and feel earthquakes from a vantage point inside the planet. Their SeismoDome show returns to Hayden Planetarium on Nov. 19, 2016, with a preview at Lamont-Doherty Earth Observatory Open House on Oct. 8.

Listening to Earthquakes – from Inside the Earth

Exploring Obama’s Seafloor Canyons by Mini Submarine

Only a few people have ever explored deep inside the seafloor canyons that President Obama just designated a national marine monument. Bill Ryan is one of them. In this podcast he describes what his team saw and learned.

Change in footprint 1993-2009. Hotter colors indicate more change. Greens indicate decrease. (Venter et al., 2016)

The (Somewhat Less Fast) Growing Human Footprint

The human footprint continues to expand, with three quarters of earth’s land surface now experiencing measurable pressures from buildings, roads, crops, pastures and other human structures and activities, according to a new report. But the report also finds an encouraging trend: In recent years, growth in the footprint has lagged far behind population and economic growth.

Construction in the Swamp

Despite the miserable weather and ongoing rain, we constructed a wooden structure to hold the GPS receivers, solar panels and other electronic equipment between the three wells. We worked out how and where to mount the antennas and had parts made to accomplish it. Although I had to leave before it was completed, the team persevered through the storm and now we will be monitoring ground subsidence and sediment compaction in the Mississippi Delta.

Visit to a Different Delta: the Mississippi

This summer I am in the Mississippi Delta in southern Louisiana helping to install an updated version of the compaction meters that we have in Bangladesh. The environment is quite different and we have arrived in the midst of an historic storm. Luckily for us the brunt of the storm is NW of us. So far, we are still able to work between the rain above and the mud below.

Project Maps the Chemistry of the World’s Oceans

Until recently, too little data existed about the distribution of trace elements and nutrients in the oceans to provide a global picture. In 2002, a group of scientists connected with Columbia University’s Lamont-Doherty Earth Observatory set out to fill those gaps.

Shipboard Science: It’s All About Collaboration This Week

Early-career scientists aboard the UNOLS training cruise are getting to try new techniques and technologies, and collaborations are springing up everywhere.

The Magic of Exploring Under the Sea

It’s midnight on the ship, and the labs are filled with scientists busy examining samples. Two of them just got back from a trip to the seafloor, and the excitement is palpable.

Life Aboard a Research Cruise: 24-Hour Workdays, Amazing Discoveries

When scientists say “research cruise,” they aren’t talking about sunny afternoons of shuffleboard and margaritas on deck. Life aboard a research vessel means tight spaces, few amenities, and long workdays.
