Scientists are turning to an unlikely ally beneath the ocean surface: sharks.

Researchers at the University of Delaware are fitting sharks with tiny CTD tags that measure temperature, salinity and depth as the animals travel through the Atlantic Ocean.

When the sharks return to the surface, the tags transmit their data to satellites, transforming their natural movements into valuable ocean observations.

Scientists hope these measurements could provide information from parts of the ocean that are difficult and expensive to monitor using conventional methods. The data could eventually help researchers better understand the ocean conditions that influence hurricane development, intensity and movement.

Sharks Become Ocean Sensors | Scientists Explore New Way to Predict Hurricanes Using Shark Movements

Scientists are turning to an unexpected ally in the fight to better understand hurricanes and changing ocean conditions — sharks.

Researchers at the University of Delaware are fitting sharks with tiny CTD tags that measure temperature, salinity and depth as the animals move through the ocean. When the sharks return to the surface, the devices transmit their collected data to satellites, transforming their natural movements into valuable ocean observations.

The research will initially focus on the North Atlantic, where scientists hope highly migratory sharks can reach deep and remote parts of the ocean that are difficult and expensive to monitor using conventional methods.

 Scientists to Turn Sharks into Ocean Sensors & Hurrican Detectors

Scientists have uncovered an extraordinary underwater discovery—a vast whale graveyard lying deep beneath the ocean surface. The site, believed to be millions of years old, contains the remains of ancient whales and offers a rare glimpse into prehistoric marine ecosystems.

What caused so many whales to end up in one location? And what can this remarkable find tell us about Earth's distant past?

Millions-Of-Years-Old Whale Graveyard Found On Ocean Floor

<p>Scientists at the California Academy of Sciences have employed a DNA-based age determination method, revealing that Methuselah, the cherished Australian lungfish residing in San Francisco's Steinhart Aquarium, is believed to be 92 years old.</p>

<p>This estimate surpasses the aquarium's previous approximation of Methuselah's age, which stood at 84 years. However, researchers caution that there is a nine-year margin of error, implying that Methuselah might potentially be as old as 101 years, according to a Live Science report.</p>

<h2><strong>A non-invasive age estimation technique</strong></h2>

<p>Determining the age of ancient fish can be a daunting task, with conventional methods often proving invasive and even lethal.</p>

<p>The technique applied to assess Methuselah's age, however, is non-invasive and benign. It entails extracting a minuscule tissue sample from a fin clip measuring less than 0.5 centimetres.</p>

Is Methuselah the world's oldest aquarium fish? DNA reveals surprising age

<p>While we all know about the conventional museums found across the world, do you know that Australia has an underwater art museum? Not just that, but a series of underwater sculptures on the Great Barrier Reef have been recently installed in the museum. According to a BBC report, the sculptures located at the Museum of Underwater Art (MOUA) have a low centre of gravity so that they are able to face the strong oceanic forces in the water.</p>

<p>The collection comprises eight different art categories with several sculptures. These sculptures have been modeled on Australian citizens who have worked in the fields of marine science and conservation of marine species, leaving a huge impact on the understanding of reef protection. It might also be thrilling to know that one of these sculptures has been modeled after Molly Steer. At the young age of just 9 years, she founded a campaign with the name ‘Straw No More’ which focuses on getting rid of single-use plastic straws. The campaign also helps encourage schools to stop using plastic straws. As a result of their efforts, more than 3,000 schools have joined the campaign and pledged to stop using single-use plastic straws.</p>

<p>These sculptures have been made from low-carbon earth-friendly concrete and reinforced with stainless steel. They are designed such that they can be colonised by the surrounding marine life, and become a part of the ecosystem. It is believed that various species such as corals and sponges will grow on and around these sculptures within the coming few years. This will alter the appearance of the sculptures in unpredictable ways.</p>

<p>One of the users commented on BBC's post, “Future marine biologists are going to be confused as hell." &nbsp;</p>

<p>“Archeologists in 3,000 years after discovering an ancient civilisation and reimagining how civilisation works," read another comment.</p>

<p>This unique museum is intended to spread awareness regarding coral reef conservation across the world. In 2020, when the museum first opened, it only featured floating trees, sculptures of children, and coral in planter boxes. In May 2023 other sculptures were added as a part of their third art installation. The ticket prices for the museum begin from Rs. 13,000 per head.<br />
