NASA Space Laser Missions Map 16 Years of Ice Sheet Loss

Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.  The results provide insights into how the polar ice sheets are changing, demonstrating definitively that small gains of ice in

NASA Reports Arctic Stratospheric Ozone Depletion Hit Record Low in March

Ozone levels above the Arctic reached a record low for March, NASA researchers report. An analysis of satellite observations show that ozone levels reached their lowest point on March 12, 2020, at 205 Dobson units. Although such low levels are rare, they are not unprecedented. Similar low ozone levels occurred in the upper atmosphere, or

World’s Largest Citizen Science Initiative Launched for Earth Day 2020

Earth Challenge 2020 (Earth Challenge) launched on April 9, 2020, marking the 50th anniversary of Earth Day. This project creates a global expansion of open-source citizen science data and opportunities for civic engagement.  Earth Challenge has two goals. First, to aggregate existing citizen science from around the world and make it interoperable, creating a coordinated

Less Ice, More Methane from Northern Lakes: A Result from Global Warming

Shorter and warmer winters lead to an increase in emissions of methane from northern lakes, according to a new study by scientists in Finland and the United States. Longer ice-free periods contribute to increased methane emissions. In Finland, emissions of methane from lakes could go up by as much as 60 percent.  An international study

Shedding Light on How Much Carbon Tropical Forests Can Absorb

Tropical forest ecosystems are an important part of the global carbon cycle as they take up and store large amounts of carbon dioxide. It is uncertain, however, how much these forests’ ability to take up and store carbon differ between forests with high vs. low species richness. New International Institute for Applied Systems Analysis (IIASA)

NASA Satellites Help Forecast Yellowstone Wildlife Migration

The bison population has grown rapidly during the last two decades in Yellowstone National Park. This creates complex situations for wildlife managers when the animals follow good grazing opportunities beyond the boundaries of the park and come into contact with surrounding communities. A NASA study has now found a link between climate change effects on

With a Speaker and Four microphones, Drones Can Echolocate Like Bats

Similarly to how bats use echolocation to orient themselves with their surroundings, mathematicians have found that the same can be done with microphones and a speaker on a drone with the help of algebra and geometry. This signal processing research has potential applications for people, underwater vehicles and even cars, said Mireille “Mimi” Boutin, a

Drone Companies Combine Forces to Command the Air, Land and Sea

Drones are commonly known for flying in the sky, but a new breed is rolling around on the ground and swimming in the ocean. Aquiline Drones (AD) will be powering GuardBot’s spherical and amphibious robotic vehicles via the AD Cloud. “Our new alliance with Aquiline Drones now gives us the ability to program our bots

NASA, New Zealand Partner to Collect Climate Data from Commercial Aircraft

NASA is partnering with the New Zealand Ministry of Business, Innovation and Employment, New Zealand Space Agency, Air New Zealand and the University of Auckland to install next-generation Global Navigation Satellite System (GNSS) reflectometry receivers on passenger aircraft to collect environmental science data over New Zealand. The program is part of NASA’s Cyclone Global Navigation

NASA Flights Detect Millions of Arctic Methane Hotspots

The Arctic is one of the fastest warming places on the planet. As temperatures rise, the perpetually frozen layer of soil, called permafrost, begins to thaw, releasing methane and other greenhouse gases into the atmosphere. These methane emissions can accelerate future warming—but to understand to what extent, we need to know how much methane may
