Once a tropical storm, now a sub-tropical storm, the remnants of the tropical low pressure area formerly known as 11S was spotted by NASA's Aqua satellite, still spinning in the Southern Indian Ocean.
On March 14 at 2230 UTC (6:30 p.m. EST) the remnants of Tropical Cyclone 11S were located near 29.8 degrees south latitude and 52.4 degrees east longitude, about 530 nautical miles south-southwest of La Reunion Island.

Polar cod fulfil a key role in the Arctic food web, as they are a major source of food for seals, whales and seabirds alike. But the polar cod themselves might soon be the hungry ones. Under the ice of the central Arctic, the juvenile fish are indirectly but heavily dependent on ice algae. As a result, retreating sea ice could have far-reaching impacts on the food web. Though researchers have long since suspected this relation existed, an international team of researchers led by the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research, have now successfully confirmed it.

More efficient sensors are needed to be able to detect environmental pollution. Researchers at Chalmers University of Technology have proposed a new, sophisticated method of detecting molecules with sensors based on ultra-thin nanomaterials. The novel method could improve environmental sensing in the future. The results are published in the scientific journal Nature Communications.
“This could open up new possibilities for the detection of environmental gases. Our method is more robust than conventional sensors, which rely on small changes in optical properties”, says Maja Feierabend, PhD student at the Department of Physics and the main author of the article from Chalmers University of Technology and Technische Universität Berlin.

Kamilo Beach is, arguably, the world’s dirtiest beach. Located on the southeastern coast on the island of Hawaii, the beach’s sands are littered with marine debris – most of it plastic waste washed up from the Great Pacific Garbage Patch. Among this garbage, Patricia Corcoran and Kelly Jazvac have discovered something new.

For decades, phosphorous has accumulated in Wisconsin soils. Though farmers have taken steps to reduce the quantity of the agricultural nutrient applied to and running off their fields, a new study from the University of Wisconsin–Madison reveals that a “legacy” of abundant soil phosphorus in the Yahara watershed of Southern Wisconsin has a large, direct and long-lasting impact on water quality.

Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-level rise, a new Tulane University study concludes.
The study by researchers in Tulane’s Department of Earth and Environmental Sciences and published in the open-access journal Nature Communications shows that the rate of sea-level rise in the region over the past six to 10 years amounts to half an inch per year on average.

Massive coastal flooding in northern Europe that now occurs once every century could happen every year if greenhouse gas emissions continue to rise, according to a new study.
New projections considering changes in sea level rise, tides, waves and storm surge over the 21st century find global warming could cause extreme sea levels to increase significantly along Europe’s coasts by 2100. Extreme sea levels are the maximum levels of the sea that occur during a major storm and produce massive flooding.
