A study just published in Nature Communications suggests that the Atlantic Meridional Overturning Circulation (AMOC), of which the Gulf Stream is a part, could be approaching a tipping point. The AMOC, which has been gradually weakening over the last century and is reportedly at its weakest in over a millennium, could shift from its current strong mode to a weak one, with profound implications for the global climate.
Hidden beneath the serene waters of The Bahamas lay the remnants of approximately 5,000 shipwrecks, entombed for centuries. These relics are finally seeing the light of day, thanks to an innovative project called The Bahamas Lost Ships Project, kickstarted in 2023 by Allen Exploration and In Search of Shipwrecks (ISOS).
The project has shed light on the maritime heritage of The Bahamas, particularly along the eastern flank of the Straits of Florida, a maritime corridor frequented since the 15th century.
According to reports, these shipwrecks are believed to date back to Roman times. Although the Mediterranean Sea is known for its rich history of maritime trade and naval warfare, the discovery of intact ancient shipwrecks remains a rare occurrence.
The shipwrecks were discovered during an operation intended to protect underwater heritage. UNESCO and the eight participating Member States launched this mission, recognizing the critical value of these sites in understanding our collective past.
Newfoundland, part of the easternmost province of Canada, is a place of wild nature where one can dive on WWII wrecks, in historic iron-ore mines, birdwatch, snorkel with humpback whales and kayak with minke whales. Brandi Mueller shares her adventure there.
Scientists studying endangered southern resident orcas have noticed a steady increase of mysterious gray patches and gray targets (circular lesions which may appear on concentric rings – ed.) on the whales’ skin from 2004 to 2016.
To date, researchers managed to identify six distinct types of lesions, with the two most common types being gray patches or targets. Some resemble tattooed skin.
They do not know the cause of the lesions and are worried that they could be due to underlying health problems in the struggling population.
A new study demonstrates how animals recognise self-images.
Some animals have the remarkable capacity for mirror self-recognition (MSR), yet any implications for self-awareness remain uncertain.
In a test of MSR ability in cleaner fish, mirror-naive fish initially attacked photograph models of both themselves and unfamiliar strangers. In contrast, after all fish had passed the mirror mark test, they did not attack their own (motionless) images, but still frequently attacked those of unfamiliar individuals.
The DAN Internship Program was created 24 years ago to give qualified students valuable experience in dive safety research. The scope of the program aligns with DAN’s goals of helping divers in need, promoting dive safety through education, and expanding outreach and communication initiatives.
The interns will spend time this summer at DAN’s headquarters in Durham, North Carolina, to work on various projects and research efforts.
When a swarm of tiger sharks attacked a Netflix video crew's boat, the boat was punctured, and they were forced to make an emergency landing on a beach in Hawaii.
The team had been gathering material for the David Attenborough documentary Our Planet II. They were operating an inflatable boat around the Laysan area of Northwestern Hawaiian Islands in order to capture footage of tiger sharks consuming young albatross fledglings.
Have you ever noticed that when adults speak to babies or small children, they speak in a distinctively specific manner? As if by instinct, they speak in a high-pitched voice, with clear pronunciation and longer pauses between words.
It seems that this “baby talk” is not reserved for humans. Researchers have discovered that dolphins too indulge in baby talk—by changing their characteristic whistles and frequencies—when they communicate with their offspring.
Today, researchers are using the fossils of the Olympicetus thalassodon an early toothed whale which existed around 26.5 and 30.5 million years ago, to better understand the early history and diversification of modern dolphins, porpoises and other toothed whales.
Nestled in the heart of the Philippines is a hidden gem of an island called Romblon, located in the Mimaropa region. Kate Jonker takes us there to discover the underwater treasures and rare marine species that beckon divers and photographers from all over the world.
KUALA LUMPUR, 7 June 2023: Aptly themed “Let’s stay connected with the ocean,” the 17th Malaysia International Dive Expo (MIDE) concluded with great success at its new venue at MITEC in Kuala Lumpur.
After moving from the former venue at the World Trade Center (WTC), where the expo was held for 16 years, the refreshing start at the uber modern and spacious Malaysia International Trade and Exhibition Centre (MITEC) proved to be a hit among exhibitors and visitors alike.
