Over the past 22 years, sea levels in the Arctic have risen an average of 2.2 millimeters per year. This is the conclusion of a Danish-German research team after evaluating 1.5 billion radar measurements of various satellites using specially developed algorithms.
A UW team has discovered thriving communities of bacteria in Alaskan 'cryopegs,' trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn's moon Titan, or other bodies farther from the sun.
The acidification of the oceans is recorded in the crystals of the coral skeleton. This is a new tool for studying past environmental changes and combating climate change. Such is the main conclusion of a study led by the Spanish scientist Ismael Coronado Vila, from the Institute of Paleobiology in Warsaw (Poland).
They found that ice slides over the bedrock much more than previous theories predicted of how ice on the Greenland Ice Sheet moves.
A new model based on daily oceanographic data and the movements of tagged whales has opened the potential for stakeholders to see where in the ocean endangered blue whales are most likely to be so that ships can avoid hitting them.
Coral reefs are retreating from equatorial waters and establishing new reefs in more temperate regions, according to new research in the journal Marine Ecology Progress Series. The researchers found that the number of young corals on tropical reefs has declined by 85 percent - and doubled on subtropical reefs - during the last four decades.
Carbon dioxide emissions may trigger a reflex in the carbon cycle, with devastating consequences, study finds.
An unprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico--and it's likely here to stay. Scientists at the University of South Florida in St. Petersburg's College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum Belt, as reported in Science.
Researchers have revealed that atmospheric waves originating from convection over the Indian Ocean had a dramatic impact on climate conditions over South America and South Atlantic, leading to drought and marine heatwaves. Importantly, these conditions are not a one-off and are likely to happen again.
Instability hidden within Antarctic ice is likely to accelerate its flow into the ocean and push sea level up at a more rapid pace than previously expected. Even if images of vanishing Arctic ice and mountain glaciers are jarring, their potential contributions to sea level rise are nowhere near those of Antarctica, the leviathan of sea level rise.
