Stanford scientists have discovered that some purple sea urchins living along the coast of California and Oregon have the surprising ability to rapidly evolve in acidic ocean water â€" a capacity that may come in handy as climate change increases ocean ...

The largest harmful algae bloom in Lake Erie's recorded history was likely caused by the confluence of changing farming practices and weather conditions that are expected to become more common in the future due to climate change. Rather than an ...

Virginia Tech College of Engineering researchers have unveiled a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds. The prototype robot, nicknamed Cyro, is a larger model of ...

Scientists have confirmed the discovery of the first-ever, two-headed bull shark. The study, led by Michigan State University and appearing in the Journal of Fish Biology, confirmed the specimen, found in the Gulf of Mexico April 7, 2011, ...

Stingrays living in one of the world's most famous and heavily visited ecotourism sites â€" Stingray City/Sandbar in the Cayman Islands â€" have profoundly changed their ways, raising questions about the impact of so-called "interactive ecotourism" on marine wildlife, ...

The Seal Protection Action Group (SPAG) today condemned the Scottish Government for publishing details about the shooting of hundreds of seals in Scotland on an obscure website, so avoiding public scrutiny and further public outrage at the killings. The Marine ...

Models of carbon dioxide in the world's oceans need to be revised, according to new work by UC Irvine and other scientists published online Sunday in Nature Geoscience. Trillions of plankton near the surface of warm waters are far more ...

Oil from the 2010 Deepwater Horizon spill acted as a catalyst for plankton and other surface materials to clump together and fall to the sea floor in a massive sedimentation event that researchers are calling a "dirty blizzard." Jeff Chanton, the ...

A tagging study has revealed that porbeagle sharks in the Gulf of St. Lawrence could severely impact the number of migrating American eels in the region. Canadian researchers tagged eight adult eels in the St. Lawrence River as part of ...

All living organisms rely on iron as an essential nutrient. In the ocean, iron's abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean's food web. A new study by biogeochemists ...

Imagine trying to swim through a pool of honey. Because of their small size, this is what swimming in water is like for tiny marine plankton. So, it was often assumed they would be easy prey, especially in the dense ...

Salmon are beginning to swim up the Elwha River for the first time in more than a century. But University of Washington marine geologists are watching what's beginning to flow downstream â€" sediments from the largest dam-removal project ever ...

The earthquake zones off of certain coastsâ€"like those of Japan and Javaâ€"make them especially vulnerable to tsunamis, according to a new study. They can produce a focusing point that creates massive and devastating tsunamis that break the rules ...

In a study published today in Nature Climate Change researchers used the latest emissions scenarios and climate models to show how varying levels of carbon emissions are likely to result in more frequent and severe coral bleaching events. Large-...

The islands Reunion and Mauritius, both well-known tourist destinations, are hiding a micro-continent, which has now been discovered. The continent fragment known as Mauritia detached about 60 million years ago while Madagascar and India drifted apart, and ...

Oceana, the largest international advocacy group working solely to protect the world's oceans, uncovered widespread seafood fraud across the United States, according to a new report released today. In one of the largest seafood fraud investigations in the world to ...

Sophisticated computer modeling has shown how sea-level rise over the coming century could affect some regions far more than others. The model shows that parts of the Pacific will see the highest rates of rise while some polar ...

Shark attacks in the U.S. reached a decade high in 2012, while worldwide fatalities remained average, according to the University of Florida's International Shark Attack File report released today. The U.S. saw an upturn in attacks with 53, the most ...

The mystery of how salmon navigate across thousands of miles of open ocean to locate their river of origin before journeying upstream to spawn has intrigued biologists for decades, and now a new study may offer a clue to the ...

A cluster of tapeworm eggs discovered in 270-million-year-old fossilized shark feces suggests that intestinal parasites in vertebrates are much older than previously known, according to research published January 30 in the open access journal PLOS ONE ...

The term "shark attack" is typically used by the media, government officials, researchers and the public to describe almost any kind of human-shark interaction â€" even those where no contact or injury occurs between humans and sharks. Now, Christopher ...

New research by the University of Southampton has found a mechanism as to how corals use their pink and purple hues as sunscreen to protect them against harmful sunlight. Many reef corals need light to survive, as they benefit from ...

The benefits and side effects of dissolving particles in our ocean's surfaces to increase the marine uptake of carbon dioxide (CO2), and therefore reduce the excess amount of it in the atmosphere, have been analysed in a new study published ...

Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next. Scientists in the past 20 years have recognized that salmon stocks vary not only ...

Researchers with the Florida Fish and Wildlife Conservation Commission (FWC) documented fewer manatee deaths in 2012 than in the previous three years, as milder winter temperatures led to significantly less cold-related mortality. The FWC recorded 392 manatee carcasses in state ...

Scientists have cast doubt on the widely held perception that there has been a global increase in jellyfish. Blooms, or proliferations, of jellyfish can show a substantial, visible impact on coastal populations â€" clogged nets for fishermen, stinging waters for tourists, ...

Someday, Oahu's Koolau and Waianae mountains will be reduced to nothing more than a flat, low-lying island like Midway. But erosion isn't the biggest culprit. Instead, scientists say, the mountains of Oahu are actually dissolving from within. "We ...

Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large ...
