AI Technology Enhances Understanding of Continental Hydrology

Changes to water masses which are stored on the continents can be detected with the help of satellites. The data sets on the Earth’s gravitational field which are required for this, stem from the GRACE and GRACE-FO satellite missions. Using the South American continent as an example, the Earth system modellers at the German Research Centre for Geosciences GFZ, have developed a new Deep-Learning-Method, which quantifies small as well as large-scale changes to the water storage with the help of…

Heavy Metals Reduce Soil Enzyme Activity by 3 Times

Heavy metals suppress enzyme activity in the soil by 3-3.5 times and have especially prominent effect on the enzymes that support carbon and sulfur circulation. This was discovered by a soil scientist from RUDN together with his colleagues from Chile, Germany, the UK and Venezuela. The data obtained by the team can lead to more efficient use and fertilization of agricultural lands. The results of the study were published in the Science of the Total Environment journal. Soil enzymes promote…

Meteorite Strikes Create Unique Silica Forms on Earth

When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach scientists about the minerals existing at the high-temperature and pressure conditions found deep inside the planet? New work led by…

New Insights on Young Tree Seedlings’ Early Growth Challenges

The first few weeks of a tree seedling’s life can be the most precarious. As it pushes thin new roots into the ground it’s also reaching up with tiny new leaves. Water and energy are precious. Most seedlings never make it past their first month on the ground. But while much is known about the growing process, there remains a layer of mystery around the mechanisms within these small plants. Now, a new study by a University of Georgia researcher…

East Antarctic Melting Hotspot Discovered Under Shirase Glacier

Ice is melting at a surprisingly fast rate underneath Shirase Glacier Tongue in East Antarctica due to the continuing influx of warm seawater into the Lützow-Holm Bay. Hokkaido University scientists have identified an atypical hotspot of sub-glacier melting in East Antarctica. Their findings, published in the journal Nature Communications, could further understandings and predictions of sea level rise caused by mass loss of ice sheets from the southernmost continent. The 58th Japanese Antarctic Research Expedition had a very rare opportunity to…

Tyrannosaurus Rex: A Closer Look at Slipped Discs in Dinosaurs

The intervertebral discs connect the vertebrae and give the spine its mobility. The disc consists of a cartilaginous fibrous ring and a gelatinous core as a buffer. It has always been assumed that only humans and other mammals have discs. A misconception, as a research team under the leadership of the University of Bonn has now discovered: Even Tyrannosaurus rex could have suffered a slipped disc. The results have now been published in the journal “Scientific Reports”. Present-day snakes and…

NASA-NOAA Satellite Monitors Hurricane Genevieve Overnight

NASA-NOAA’s Suomi NPP satellite kept an eye on Hurricane Genevieve overnight and provided infrared imagery to forecasters who were monitoring the storm’s strength, structure and size. Because Genevieve is close to the coast of western Mexico, warnings and watches were still in effect. NASA’s Night-Time View of Genevieve The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a nighttime image of Hurricane Genevieve on Aug. 18 at 8 p.m. EDT (Aug. 19 at 0000 UTC).The hurricane’s eye…

NASA Study Reveals Causes of Global Mangrove Loss

Using high-resolution data from the joint NASA-U.S. Geological Survey Landsat program, researchers have created the first map of the causes of change in global mangrove habitats between 2000 and 2016 – a valuable tool to aid conservation efforts for these vital coastline defenders. Mangroves are hardy trees and shrubs that grow in the salty, wet, muddy soils of Earth’s tropical and subtropical coastlines. They protect the coastlines from erosion and storm damage; store carbon within their roots, trunks, and in…

NASA Observes Water Vapor in Tropical Depression 10E

Tropical Depression 10E weakened to a remnant low-pressure area in the Eastern Pacific Ocean. NASA’s Terra satellite observed the water vapor content in the storm. At 5 p.m. EDT on Sunday, Aug. 16, NOAA’s National Hurricane Center noted that the depression had been devoid of organized deep convection for the previous 24 hours at at that time and lacked any convection. NHC therefore classified 10E as a post-tropical as a non-convective remnant low-pressure area. Water vapor analysis of tropical cyclones tells…
