Researchers in Southern California are seeing more great white sharks than ever before, reports local broadcast network KCAL-TV.

Chris Lowe, a shark expert at California State University Long Beach, tells KCAL-TV that his lab tagged a record 38 great whites—more than three times the number they tagged last year. “This year there were just more sharks around, and the question is why,” says Lowe.

But scientists emphasize an important qualifier: The great whites cruising the Southern California coast are babies and juveniles that tend to be between four and ten feet long. These skittish young sharks stick close to shore to avoid predators and snack on stingrays and fish.

They also mostly avoid people, even as they’re becoming more numerous.

“Despite the fact that shark p...

This year’s Great British Beach Clean, hosted by the Marine Conservation Society (MCS), has found that face masks and gloves were found on nearly 30% of beaches cleaned by Marine Conservation Society volunteers over the week-long event. The inland Source to Sea Litter Quest data shows a similarly alarming presence of masks and gloves, with more than 69% of litter picks finding PPE items.

“The amount of PPE our volunteers found on beaches and inland this year is certainly of concern,” said Lizzie Prior, Great British Beach Clean Coordinator at the MCS...

Joe Biden’s plan to tackle climate change has been described as the most ambitious of any mainstream US presidential candidate yet. Our environment correspondent Matt McGrath considers what he wants to do, and how he might get it done. Much will be made about Joe Biden’s pledge to re-join the Paris climate agreement, the international pact designed to avoid dangerous warming of the Earth. President Trump pulled out of the deal after the Obama administration had signed up in 2016, and during the drawn-out election count, Mr Biden confirmed that reversing the decision would be one of his first acts as president.

But key to his credibility on the international stage will be his domestic policies on cutting carbon emissions.

More radical Democrats such as congresswoman Alexandria Ocasio...

Our environment has taken a serious beating over the past few decades, with climate change accelerating at an unprecedented pace. However, in some good news coming from the natural world, scientists have just discovered a massive chunk of coral reef off the Australian coast.

On Oct.20, a vast, detached coral reef was found in the Great Barrier Reef, the first in more than 120 years. 

At more than 1,640 feet (500m) — higher than the Empire State Building — the reef was found by a team on a year-long exploration of the waters surrounding Australia. 

The reef was discovered by Australian research scientists on board the Schmidt Ocean Institute’s research vessel Falkor while mapping the seafloor of the northern Great Barrier Reef. 

The base of the blade-like reef is 1...

We should be eating more jellyfish if we want to save the planet, says new research.

Scientists at the University of Queensland, Australia say we should be increasing our consumption of jellyfish worldwide, in order to protect threatened fish species and safeguard marine conservation efforts. Fishing is an ongoing threat to 96 per cent of threatened fish species, and the only ongoing threat for some, according to the IUCN.

The research found that 91 globally threatened species of fish are being legally caught on an industrial scale. Around 15 per cent of these species are traded internationally, mainly for consumption across Europe. This includes fish like haddock, Atlantic horse mackerel, and bigeye tuna. 

“It should be illegal to eat something that is threatened by extinction, ...

A new study, published in the Proceedings of the National Academy of Sciences, found that protecting an additional 5% of the ocean can increase future fish catch by 20% or more. Growing up in a fishing community in the Philippines, lead researcher Dr. Reniel Cabral believes that marine protected areas (MPAs) can benefit both conservation and fisheries goals simultaneously. In the past, MPAs have been used as conservation tools, however a focus on fisheries may provide a necessary incentive for many coastal nations to adopt or expand them. 

“We are curious if we design MPAs to increase fisheries productivity on a global scale, how much food can we generate, and how expensive will it be?” says Dr. Cabral, who hopes to see 30% of the world’s oceans protected by 2030; a widespread co...

A groundbreaking new online tool called Whale Safe has been created by marine scientists and top whale researchers from across the country, including Texas A&M University at Galveston’s Dr. Ana Širović. The tool allows users to detect the endangered animals in order to mitigate vessel strikes and increase conservation efforts of the endangered marine species.

Displaying near real-time data to help prevent ships and whales from colliding, Whale Safe is an analysis and mapping tool designed to lessen the chance of a strike or collision...

All coral reefs start off as a single polyp. A polyp is essentially a small tissue from the surface inside the body, somewhat similar to a sea anemone. Stony coral species live in colonies and discharge calcium carbonate, which acts as an external skeleton. Like jellyfish and sea anemone, which are their relatives, coral polyps have tentacles that are used to catch food. The tentacles are tucked away during the day, but reach out to catch their prey, mainly plankton, by stinging them.

On an annual basis, coral reefs release their gametes (reproductive cells) simultaneously. This phenomenon is most likely prompted by the right phase of the lunar and solar cycles as well as optimum water temperature...

Coral around the world has been dying at unprecedented rates, largely the result of warming ocean waters due to climate change. Now, the International Coral Reef Society’s scientists have published what they call the “Pledge for Coral Reefs,” a list of 12 actions everyone can take to help protect coral and coral reefs.

“This is an educational tool to remind people that, ‘Wow, when I purchase products with single-use plastic, that affects coral reefs. When I don’t eat sustainably, that affects coral reefs. If I don’t vote, that affects coral reefs. So many environmental and climate change related issues impact coral reefs,” said Andréa Grottoli, professor of earth sciences at The Ohio State University and president of the International Coral Reef Society.

“Each of th...

The alert about the latest shark attack came last Friday: a surfer was missing; his board dragged from the waves bearing bite marks. Western Australian authorities have since called off the search for Andrew Sharpe, 52, confirming he was mauled by a shark.

Friends who witnessed the attack said he had been knocked off his board and pulled underwater. Police divers later found scraps of his wetsuit.

His death in Wylie Bay, a popular surf spot, marks the seventh fatal shark attack in Australian waters this year, causing alarm among beach-going communities.

Not since 1929 – when there were nine fatalities – have there been so many.

So is there something in the water, or is 2020 an anomaly? 

What do the numbers show?

Looking at the total number of shark attacks reported – fat...
