Using GPS Data to Help Cities in Emergencies

In October of 2012, Hurricane Sandy struck the East Coast of the United States causing billions of dollars in damage. The super storm became the most destructive hurricane of the season but it also provided transportation researchers a new way to analyze the effect that extreme events have on traffic […]

Spatial Analysis

Using Landsat images analyzed by a neural network, Anemone and his colleagues created a land cover map of the Great Divide Basin. Potential fossil locations are light red, and likely locations are dark red.

Finding Fossils with Remote Sensing

In the field of paleontology, finding fossils is often a substantial undertaking. Researchers usually have to assemble crews of up to 15 people, each one carrying their own food and shelter, and head out into remote areas where making good time means driving 10 miles an hour. On top of […]

GIS Data

Using 200 million measurements collected by ESA’s CryoSat mission between January 2011 and January 2014, researchers from the Alfred Wegener Institute in Germany have discovered that the Antarctic ice sheet is shrinking in volume by 125 cubic kilometres a year. The study, which was published in a paper published on 20 August 2014 in the European Geosciences Union’s Cryosphere journal, also showed that Greenland is losing about 375 cubic kilometres a yearUsing 200 million measurements collected by ESA’s CryoSat mission between January 2011 and January 2014, researchers from the Alfred Wegener Institute in Germany have discovered that the Antarctic ice sheet is shrinking in volume by 125 cubic kilometres a year.

CryoSat Shows Record Loss of Polar Ice

Scientists concerned about climate change are closely monitoring the thickness of polar sea ice. For many years, ice cover has been deemed a significant gauge of global warming’s impact on the Earth. The loss of sea ice in the Arctic and Antarctica could speed up the rate of global warming, […]

Mapping the Outbreaks of Diseases

In August of 2014, the World Health Organization declared a public emergency in response to the growing number of Ebola cases that have struck several West African countries. So far, the countries that have been hit hardest include Nigeria, Liberia, Sierra Leone, Guinea, and Senegal. In those countries, more than […]
