Water covers more than two-thirds of the Earth’s surface and the vast oceans are home to a myriad of creatures and one of the biggest animals of the world. People have always been curious to explore the mysteries of the underwater realm, and thanks to technology, explorers and filmmakers can bring the natural world into our living rooms. Here are some of the most memorable ocean documentaries that everyone with a keen interest in the marine environment will surely enjoy.

With the ongoing coronavirus pandemic affecting many of Earth’s nations, healthcare systems throughout the world have been knocked off balance. Coronavirus victims face a risk of pneumonia and acute respiratory syndrome, and ventilators are a critical care tool for patients with severe cases of coronavirus. The shortage of breathing devices has prompted nations worldwide to come up with innovative solutions. A team of doctors and engineers from Italy, one of the worst affected countries by the COVID-19 outbreak, has come up with a crafty invention designed to meet the demands of the pandemic.

The travel and leisure industry has been hit hard these past few months following the outbreak of the novel coronavirus (COVID-19), which has had disruptive effects on economies worldwide. The diving community has not been spared either. Recently, the Divers Alert Network (DAN) and several major diving organizations such as PADI and SDI have taken to the internet to discuss the issue, including the health and safety precaution measures one needs to take during this period.

Coral reef diving is an all-time favorite to most recreational divers. Those vibrant, beautiful underwater reefs filled with coral of all shapes and sizes attract travelers from all parts of the world. But not all coasts are bordered by reefs and not all dive sites feature colorful fields of coral. Luckily, this doesn’t mean those places don’t offer other attractions. Some of the best experiences you can ever have as a diver involve something known as “muck diving”, which we can all agree it does not sound too exciting, but it’s worth it. Here’s why.

More than 70 years have passed since World War II ended, but aircraft and warship remains are still being discovered in various parts of the world. Recently, the group Project Recover announced the discovery and identification of wreckage belonging to three U.S. aircraft lost during the 1944 Operation Hailstone, which took place on Truk Lagoon, now known as Chuuk Lagoon.

Earlier this year, the World Travel Awards made the first stop of their annual Grand Tour in The Bahamas, where key sectors of the travel, tourism, and hospitality industries in the Caribbean region were rewarded for their accomplishments. The votes are in and we now know what’s the hottest place to dive in the Caribbean in 2020. Unsurprisingly for many well-traveled divers, the Cayman Islands have been yet again recognized as the Caribbean’s Leading Dive Destination at the first regional gala ceremony, which took place at the end of January in Nassau.

The mammalian diving reflex, or diving response, is a set of evolutionary adaptations that date back to billions of years ago when all life was aquatic. All mammals have the reflex to preferentially divert oxygen supplies to the heart and the brain during submersion. The diving response is very strong in water mammals, such as whales and seals, and it is the physiological adaptation that allows them to dive for food to great depths between surface breaths. 

Cave diving is considered one of world’s most dangerous sports. Divers must undergo extensive training to receive their cave diving certification due to the inherent challenges that come with diving in an overhead environment. Always looking to push their limits, cave divers often find themselves in risky situations. Even with today’s modern equipment and technology, dozens of people die each year in the dark chambers and passages of underwater caves. Below are some of the most dangerous cave dives on Earth, from which many have failed to return.

Scuba diving and snorkeling are popular holiday activities in most parts of the world. As an important tourism market, the scuba diving industry generates billions of dollars yearly. Millions of certifications are issued globally every year, but while the industry is thriving, can the same be said about the overstressed ecosystems? The fragile marine ecosystems are at risk as the ecological pressure on the environment increases. Luckily, there are a few things both divers and dive operators can do to protect the environment, which is to practice and promote sustainable diving.

The most common of the breathing gases is compressed air (filtered and dehumidified), which is a mixture of 21% oxygen, 78% nitrogen, and 1% other trace gases. Since it falls within the limits of recreational diving, unlike specialized mixtures, it does not require additional training. However, once you reach a certain level of experience and confidence, you may want to dive into the world of diving gas mixes. And here’s why.
