Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A study from the University of California, Davis, identifies the parasite’s specific strains that are killing southern sea otters, tracing them back […]

A 100-year flood is supposed to be just that: a flood that occurs once every 100 years, or a flood that has a one-percent chance of happening every year. But Princeton researchers have developed new maps that predict coastal flooding for every county on the Eastern and Gulf Coasts and find 100-year floods could become […]

Geothermal manifestations at Earth’s surface can be mapped and characterized by a variety of well-established exploration methods. However, mapping hydrothermal vents in aquatic environments is more challenging as conventional methods can no longer be applied. In fact, chemical composition of lake water may indicate inflow of fluids from a volcanic system, but it does not […]

New research finds that a warming planet will also alter ocean waves along more than 50% of the world’s coastlines. This research, published in Nature Climate Change, has significant implications for coastal flooding and erosion. As part of the Coordinated Ocean Wave Climate Project, ten research organisations, including the National Oceanography Centre (NOC), combined to […]

34 million years ago the warm ‘greenhouse climate’ of the dinosaur age ended and the colder ‘icehouse climate’ of today commenced. Antarctica glaciated first and geological data imply that the Atlantic meridional overturning circulation, the global ocean conveyor belt of heat and nutrients that today helps keep Europe warm, also started at this time. Why […]

Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, researchers reporting in ACS’ journal Environmental Science & Technology have studied natural sources of CO2 release off […]

Longline fisheries around the world are significantly affecting migrating shark populations, according to an international study featuring a University of Queensland researcher. The study found that approximately a quarter of the studied sharks’ migratory paths fell under the footprint of longline fisheries, directly killing sharks and affecting their food supply. Dr Bonnie Holmes, from UQ’s […]
