Zappa is partial to solar-powered drifters that connect to sensors on the seafloor or in the water column and can telemeter data to satellites for real-time monitoring.
Crone has spent much of his career developing instrumentation for a different kind of remote sensing system: a seafloor observatory with a fiber-optic cable running miles from the coast of Oregon to an array of sensors. The sensors are now sending back real-time observations from Axial Seamount, a submarine volcano at a mid-ocean ridge where new ocean floor is being created.
Marine geophysicist Maya Tolstoy used the real-time data to study a eruption there, starting with an uptick in earthquakes ahead of the eruption and monitoring how energy from the eruption moved through the water. Seafloor image: GeoMapApp. All of this incoming data raises the demand for computer power and for smart ways to process and archive it.
The Interdisciplinary Earth Data Alliance , led by Kerstin Lehnert and Suzanne Carbotte at Lamont, plays a crucial role by storing scientific data from scientists around the world and making the data widely available along with tools for analysis.

The middle of the 20th century began what has been dubbed a "Great Acceleration," a rapid and profound transformation of humanity's relationship with the natural world.
We populate the Earth with seven billion people, with two billion more soon to follow. We develop and urbanize landscapes and build artificial islands off the coasts of Dubai and China. We move mountains to extract coal, we level rain forests, we drain wetlands.

We carry invasive species to new locations and destroy habitat for other species, causing a crisis of mass extinction. We dam some of the planet's greatest rivers for hydroelectric power and deplete aquifers to grow crops. Copy the HTML code below to embed this book in your own blog, website, or application.
