Mapping Ice Algal Blooms from Space
Satellite data reveal how colorful algae are melting the Greenland ice sheet.
How Do Intergranular Particles Affect the Flow of Ice?
Laboratory experiments that indicate rock particles can impede sliding along grain boundaries in ice may help researchers more accurately determine the composition of planetary ice masses.
Using Multiple Models to Improve Seasonal Forecasting
The first study to examine the ability of a suite of general circulation models to predict sudden warmings in Earth’s stratosphere highlights the potential for improving Northern Hemisphere forecasts.
Old Idea Spurs New Research into Origins of Carbonate Mudstones
Using modern techniques, scientists tested an old hypothesis about carbonate mud production to shift the thinking about rocks that are used as seawater archives and a source of petroleum.
How Yellowing Seas Will Affect Ocean Temperatures
Materials that trap solar heat at the sea surface could cause more extreme temperatures.
Very Warm Water Observed Along West Antarctic Ice Shelf
Two years of mooring observations at the edge of the continental shelf show that wind stress and upwelling control the inflow of some of the warmest water observed at an ice shelf front in Antarctica.
Secrets from the New Madrid Seismic Zone’s Quaking Past
High-resolution lidar topography reveals a long history of ancient earthquakes.
Unraveling the Origins of a Record-Setting Marine Heat Wave
The extreme heat wave in the southwestern Atlantic in 2017 was likely caused by upper atmosphere circulation patterns triggered by the Madden-Julian Oscillation tropical weather cycle.
What Climate Models Get Wrong About Future Water Availability
Models that accurately represent past and present rainfall provide more accurate projections of water availability, a new study suggests.
