If you studied evolution in school, you probably remember that chart that showed fish living in the water and then moving onto land. Watching the blenny species of fish is like seeing evolution happen. Fish are supposed to live in the water; it’s one of their defining characteristics. But in the case of the blenny, evolution has allowed it to also survive on land — in fact, the fish might not be able to survive without it.
Red tides – where seawater appears to turn red due to a high concentration of toxin-producing dinoflagellates – don’t happen at random, a study has found, proposing the first method to predict when red tides will occur in southern California.
Findings of a new study have revealed that the Earth’s oceans are warming far faster than scientists previously believed. The research, which was published in the journal Science Advances on Friday, March 10, and used data from thousands of robotic floats that measured water salinity and temperature, showed that the rate of ocean warming has nearly doubled since 1994 when compared with that which occurred in earlier decades.
The world’s biggest environmental network is calling for a global ban on microscopic plastics that it says are quietly harming the world’s oceans. The International Union for Conservation of Nature says that unlike larger plastic wastes that are well known as ocean pollutants, microplastics are not visible.
In a mysterious change to their normal behaviour, humpback whales are forming massive groups of up to 200 animals. Humpbacks aren’t normally considered to be terribly social. They are mostly found alone, in pairs, or sometimes in small groups that disband quickly.
On March 8, 2014, Malaysia Airlines Flight 370 vanished with 239 passengers and crew aboard as it crossed the Indian Ocean, triggering a large-scale search for its remains that lasted nearly three years. As a byproduct of the tragedy, scientists have gained access to more than 100,000 square miles of seafloor mapped at a level of detail that provides a rare look at the ocean’s geological processes.
Last Wednesday, we hosted our annual public policy forum – Feeding the Future: An Ocean of Opportunity. I was extremely pleased with the attendance by so many people from diverse communities – academic, congressional, agency, industry, military – participating, both as speakers and as active members of our audience.
The Arctic has been losing sea ice over the past several decades as Earth warms. However, each year, as the sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.
The 14th Urbino Summer School in Paleoclimatology (12-28 July) will provide graduate students with an intensive program on reconstructing the history and dynamics of paleoclimate through an integrated series of lectures, investigations, case studies, and …
At high latitudes, such as near Antarctica and the Arctic Circle, the ocean’s surface waters are cooled by frigid temperatures and become so dense that they sink a few thousand meters into the ocean’s abyss. Ocean waters are thought to flow along a sort of conveyor belt that transports them between the surface and the deep in a never-ending loop. However, it remains unclear where the deep waters rise to the surface, as they ultimately must. This information would help researchers estimate how long the ocean may store carbon in its deepest regions before returning it to the surface.
The Chancellor and the Board of Regents of the University System of Maryland invite nominations and applications for the position of President of the University of Maryland Center for Environmental Science (UMCES). UMCES is a …
