Fewer species found in the oceans than previously realized

A new catalog of ocean life, called World Register of Marine Species (WoRMS), has reassessed the number of species found in the oceans. Having found some duplicates, the number of ocean-going animals has been reassessed downwards.

Ocean animals are getting progressively larger

Ocean animals have been getting larger over the millennium. According to a new analysis, reviewing thousands of species from the Earth’s seas since the Cambrian Period, there has been a gradual uplift in size.

Oceans are warming so rapidly they are breaking scientific charts

Earlier this month the NOAA and NASA announced that 2014 was the hottest year ever recorded, shattering the previous records in 2005 and 2010. Now comes the news that global warming is heating the world's oceans at an unprecedented pace.

Plastic waste builds up to record volume in the oceans

A new survey has revealed the full extent of the plastic problem in the world’s oceans. The research estimates more than 5 trillion pieces weighing nearly 250,000 tons are floating through the seas.

Tiny animals could drive the motion of the oceans

A new study has shown that the collective swimming of brine shrimp impacts water currents. This has led some scientists to speculate that the motion of the world's oceans is dependent upon the swimming of tiny marine animals.

Obama to create world's largest marine sanctuary

Washington - US President Barack Obama will create the world's largest marine sanctuary in the Pacific Ocean in a bid to protect sea life from climate change, the White House said.

Changing oceans affecting calcification of marine organisms

The ocean is home to many creatures, and all of them take their sustenance from this environment. One group of organisms use the ocean's calcium to create their shells and exoskeletons. These are the calcifiers, the mollusks, corals and starfish.

Plastic debris coats 88 percent of the world's oceans

Results from a study carried out during an around-the-world cruise by a research ship, scientists have found that 88 percent of the oceans' surface contains plastic debris, leading to concerns about the effects on both marine life and the food chain.

U.S. joins bid to create vast Pacific marine reserve

Washington - The United States joined forces with other nations to declare a vast swath of the Pacific Ocean a marine sanctuary and take "historic" steps to combat illegal fishing.

Kerry issues urgent call to save oceans

Washington - US Secretary of State John Kerry sounded the alarm Monday on the perils facing the world's oceans, calling for a global strategy to save the planet's life-giving seas.

US hosts talks to save oceans under 'siege'

Washington - US Secretary of State John Kerry launches an unprecedented global effort Monday to save the world's oceans under siege from overfishing, climate change and pollution.

Study: Incredible ocean discovered near the center of the Earth

Evanston - Researcher Steven Jacobsen claims to have found evidence of an incredibly huge reservoir of water near the center of the earth.

Video: Unknown sea creature devours massive shark

Scientists had tracked a healthy and massive shark in the waters around Australia. They were terribly shocked when their tracking device showed up on an Australian shoreline.

Monitoring the health of humpback whales

Researchers have identified a core skin bacterial community that all humpback whales share across populations. Monitoring these bacteria could point to a way to assess the overall health of these endangered marine mammals.

Plastic pollution of oceans is a growing menace

Microbes living on floating pieces of discarded plastic are affecting the ocean ecosystem. This plastic pollution poses a significant risk to invertebrates, humans and other animals.

Sharks used to track global warming

Strapping sophisticated sensors to sharks’ fins, researchers aim to collect temperature and other environmental data from the far reaches of the Pacific.

Dinosaur skin color revealed for the first time

Stockholm - Scientists have recovered original skin pigments from three ancient marine reptile fossils. For first time the best assessment yet of the color of dinosaur skin has been made.

Jellyfish bloom ‘like flowers’

Scientists are trying to understand why, in the spring, jellyfish emerge in the sea in high numbers. The effect has been described as "blooming like flowers." A biochemical trigger is thought to play a part.

How do dolphins swim? (video)

West Chester - Dolphins swim by exerting minimum effort, according to a new study. This finding overturns an 80-year-old paradox that argues dolphins are not designed for swimming.

Ancient sharks may have survived the 'great extinction'

A new fossil find suggests that some ancient sharks may have survived a mass extinction event 350 million years ago (sometimes referred to as 'the Great Dying').

Reading climate change by looking at the shells

Climate changes from millions of years ago are recorded at daily rate in sea shells. Studying ancient sea shells can provide valuable information about changes to the Earth’s environment.

Measuring climate change at the sea floor

Tracking the development of microbial life at the level of the sea bed has proved to be a useful indicator of climate change. A new study reveals the changing features.

Wet Dreams at Philadelphia's SPACE 1026

Philadelphia - Wet Dreams is a mixed-media installation inspired by deep sea celestial voyaging, surfing, and the mysticism surrounding the ocean. Its opening reception is this Friday at SPACE 1026, a Philadelphia-based artist collective.

Rising temperatures affect the natural cycles of the oceans

New research indicates that rising ocean temperatures, caused by a warming of the Earth’s atmosphere, will upset natural cycles of carbon dioxide, nitrogen and phosphorus.

Killer whales identified as ‘two different species’

A new study of the DNA of killer whales has confirmed that there are at least two different species of orca swimming in the world’s oceans.

Climate change impacts on the oceanic food chain

Climate change appears to be affecting the starting point of the ocean’s food chain. Changing climate is affecting the types of microscopic organisms found in the seas, with potential consequences for marine life and human health.

Are undersea Internet cables too vulnerable?

Our dependence on the Internet grows daily. Should we be concerned about the apparent vulnerability of the undersea Internet cables that connect us?

The world's giant squids are 'a single species'

New research based on molecular analysis indicates that all the giant squids found around the world's seas and oceans belong to the same species.

Saving the western and central Pacific Ocean bigeye tuna

Scientists at the University of Hawaiʻi at Mānoa, have suggested their research may have found a way forward to help the ill-fated bigeye tuna.
