Artificial intelligence and extensive satellite imagery have allowed researchers to map the world's intertidal zones for the first time, revealing a significant loss of the crucial ecosystem. The study has shown that global foreshore environments declined by up to 16 percent between 1984 and 2016.
A new study finds that hypoxic dead zones occur in nutrient-laden urban streams, not just in coastal waters. The research shows that intense storm flows can erode some stream channels to become a series of pools that trap nutrient-laden runoff. The elevated nutrient levels in the water spur greater consumption of dissolved oxygen by bacteria, causing the pools to become hypoxic until the next storm flushes them out.
Scientist show a possibility to detect the extent of debris on mountain glaciers globally and automatically vi a satellite monitoring. The scientists used the cloud computing platform Google Earth Engine for their study.
Researchers are adding specific details on landslides to the Nevada map of known hazards.
In the Mediterranean region, there are numerous UNESCO World Heritage Sites in low-lying coastal areas. In the course of the 21st century, these sites will increasingly be at risk by storm surges and increasing coastal erosion due to sea-level rise.
Scientists were able to record a sudden outburst of a glacial lake with seismometers deployed the year before in the wake of the catastrophic Ghorka earthquake in April 2015. The authors of a new study argue that such major flood events have a greater impact on erosion rates than the annual monsoon rainfalls. The reason is that the water masses mobilize large boulders and coarse sediment which usually protect the riverbed.
By including models of dynamical physical processes such as erosion and wave run-up, a team of researchers has determined that land area in Hawai'i vulnerable to future sea level rise may be double previous estimates.
