Exploring Our Changing Earth, in Real Time

Lamont-Doherty Earth Observatory scientists are loading drones with high-tech instruments and using satellites and undersea cables that are interacting with sensors in some of the most remote locations on Earth to gather data in real time and uncover the secrets of our planet.

Figure of two images. The one of the left shows 2015 estimates of population density of a coastal region in Kenya from CIESIN’s Gridded Population of the World, version 4 (GPWv4), which is based on census data. On the right, New Facebook estimates of population density in the same coastal region in Kenya. This allocation, which is derived from processing of third party satellite imagery and incorporates GPWv4, provides a higher resolution map of population distribution.

Working with Facebook to Create Better Population Maps

Knowing how settlements are distributed across the landscape—e.g., in clusters, along roads or waterways, or scattered widely—has important implications for designing infrastructure, improving access, and promoting sustainability.

The Changing Face of Air Quality

Looking at regional differences in PM2.5 concentrations gives us a sense of the changing face of air quality throughout the world.

In Haiti, Exploring What Drives People to Alter the Landscape

Study of the Pedernales Watershed, located along Haiti’s southern national boundary with the Dominican Republic, may provide insights into the stark contrast in land cover patterns between the two countries.

Sea Change

Gliders and buoys and robots — oh my!
Over and through the ocean they fly.
Oodles of data from sensors galore,
Studied by many, far from the sea’s roar.

Keeping an Eye on Coastal Erosion

Searching for a fast, simple and low-cost way to monitor Earth’s changing coastlines, a team of scientists, including Lamont-Doherty Observatory postdoctoral researcher and marine scientist Alessio Rovere, has found an innovative use for drones.

Postdoc Crosses Disciplines to Put Theory to Practice

The Earth Institute postdoc has provided me with a strong foundation to continue to initiate and develop these sorts of collaborations, has helped me learn how my own research can benefit from being challenged by and contextualized in another field, and has taught me how much fun it can be to share the same sort of challenge and insight.
