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.

The Floor of the Ocean Comes into Better Focus

The bottom of the ocean just keeps getting better. Or at least more interesting to look at.

Map fusion combines night light, population density and elevation data to show the contrast between the densely populated Ganges-Brahmaputra delta and the sparsely populated mountain ranges surrounding it. The urban cores (red) have population densities approaching 100,000 people per square kilometer, while the surrounding agricultural areas have average population densities around 1000 people per square kilometer.

A Simple Question, Unexpected Applications – and an Award

Even the simplest research questions can lead to far-reaching public benefits. Consider Chris Small and Joel Cohen’s study of global population by altitude, being honored this week at the Library of Congress.

Mapping Land Claimed by Sea Level Rise

Understanding how coastal areas changed as the ocean rose in the past could help communities protect themselves from storm surge flooding in the future as the oceans warm and sea levels rise.

Haiti 2010 earthquake

Remote Data Team Helped Put Haiti Back on the Map

Before the Haiti earthquake, few publicly available maps of the country existed. When the earthquake hit in 2010, some of the little data that existed was destroyed. Then a team at Tufts University went into action, and from afar, helped build updated maps of roads and earthquake damage to help humanitarian organizations deal with the crisis.

Mobile Maps Help Haitians Locate Government Offices

Until last month, Haitians had no way to search online to find the location of government offices. Now, thanks to a collaboration between the Earth Institute and Haiti’s government, there’s a registry of every government office accessible online and on mobile devices.

In Your Own Backyard: Mapping Communities Near Superfund Sites

The NPL Superfund Footprint Mapper is an interactive, online mapping application—a clickable map—that lets users visualize a rich variety of population and environment characteristics of areas in the vicinity of Superfund sites.

Major Spatial Data Collection Released

Urbanization poses both challenges and opportunities for sustainable development and environmental management. Improved data on patterns of human settlement and trends in population can help researchers and policy makers better understand differences between urban and rural areas in terms of their impacts on the environment and vulnerability to environmental variability and change. The newly released… read more
