Flood waters churn up toxins from riverbeds
Sediments are regarded as a river's long-term memory. They mainly comprise particles that are eroded from the ground, ending up at some point in river deltas or the sea. However, sediments can also remain stable for a relatively long time—and bind.....»»
Kamikaze bacteria explode into bursts of lethal toxins

Researchers find the more flood driving factors there are, the more extreme a flood is
There are several factors that play an important role in the development of floods: air temperature, soil moisture, snow depth, and the daily precipitation in the days before a flood. In order to better understand how individual factors contribute to.....»»
Antarctic sea ice near historic lows: Arctic ice continues decline
Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The recurring loss hints at a long-term shift in conditions in the.....»»

Estimating coastal water depth from space via satellite-derived bathymetry
Since ancient times, knowing the depth of coastal waters has been key to safe and successful navigation and to exploit the sea's resources. Today, bathymetry—the measurement of sea depth—is even more important, playing essential roles in our unde.....»»
Salt marshes put to the test in wave flume
