Towable sensor free-falls to measure vertical slices of ocean conditions.
Why do carbon dioxide levels in the atmosphere wax and wane in conjunction with the warm and cold periods of Earth's past? Scientists have been trying to answer this question for many years, and thanks to chemical clues left in sediment cores extracted from deep in the ocean floor, they are starting to put together the pieces of that puzzle.
A new study led by researchers at the Yale School of Public Health and published in the journal Lancet Planetary Health, finds that China's countrywide ban on traffic mobility from February 10 to March 14, 2020 greatly limited automobile emissions and sharply reduced the country's often severe air pollution. The improved air quality, in turn, prevented thousands of pollution-related deaths.
NASA satellites have been providing forecasters with various types of imagery on Typhoon Amphan as it heads toward a landfall near the border of eastern India and Bangladesh on May 20, 2020.
NASA-NOAA's Suomi NPP satellite passed over the western North Atlantic Ocean and provided forecasters with a visible image of Post Tropical Storm Arthur.
By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.
Early on May 18, 2020, Tropical Cyclone Amphan was a Category 5 storm in the Northern Indian Ocean. On May 19, satellite data from NASA-NOAA's Suomi NPP satellite revealed that the storm has weakened and the eye was covered by high clouds.
When the Global Precipitation Measurement mission or GPM core satellite passed over the western North Atlantic Ocean, it captured rainfall data on Tropical Storm Arthur as the storm was transitioning into an extra-tropical storm.
Scientists have discovered where a whale species that feeds around the sub-Antarctic island of South Georgia breeds during the winter months. This understanding of where the animals migrate from will enable conservation efforts for their recovery from years of whaling. The results are published this week in the Journal of Heredity.
The COVID-19 global lockdown has had an 'extreme' effect on daily carbon emissions, but it is unlikely to last -- according to a new analysis by an international team of scientists. The study published in the journal Nature Climate Change shows that daily emissions decreased by 17% -- or 17 million tonnes of carbon dioxide -- globally during the peak of the confinement measures in early April compared to mean daily levels in 2019, dropping to levels last observed in 2006.
