Proper ear care is crucial for divers to maintain a healthy ear. Earwax buildup can create a plug that traps air, leading to potential eardrum rupture due to pressure changes. It can also cause vertigo if cold water enters one ear while the other is blocked. Removing earwax is important and should be done by […]

Touching marine life is generally a bad practice, but a recent video showed dive guides actually grabbing marine life. This type of behavior is disturbing and goes against the idea of respectful interaction with ocean creatures. Most divers only touch marine life lightly, but grabbing it to perform for videos is inappropriate. It’s unclear how […]

OCEARCH’s shark tracker is a tool that helps track the movements of various marine animals, including great white sharks. Recently, there have been more sightings of these sharks along the North Carolina and South Carolina coasts. This increase is thought to be due to abundant food and favorable water temperatures in the area. Sharks can […]
Breathing techniques are essential for improving your scuba diving experience. New divers often take big breaths, which can affect buoyancy and lead to wasted air. Instead, focus on deep belly breathing, which enhances efficiency by minimizing carbon dioxide buildup. This helps divers feel less “starved” for air and allows for better control while photographing marine […]

Challenger Deep is the deepest known point in the ocean, reaching about 26,200 feet. However, it is not the deepest point on Earth. The Kola Superdeep Borehole in Russia goes even deeper, measuring 40,230 feet. Drilling for this borehole took 20 years and stopped due to high temperatures. This highlights that the depths of our […]
Great white sharks are making a comeback in the North Atlantic, especially near Cape Cod. Since being granted federal protection in 1997, their numbers have risen significantly. Many sharks are now spotted close to the shore, drawn by their favorite prey, grey seals. Researchers are tagging these sharks to study their movement and behavior, confirming […]

Scuba diving can lead to some amusing moments, especially during entry fails. Videos show divers being tossed into the water, which can be entertaining but also concerning for safety. Even professional divers can have trouble with back entries, resulting in comical situations. It’s important to remember that everyone was a beginner at some point, and […]
Diver’s Lift Chair is a new innovation for safely lifting scuba divers from the water. The chair is used at the Frying Pan Tower, a structure 90 feet above sea level in the Atlantic Ocean.

When buying a new scuba regulator, it’s important to understand the differences between lower-end and higher-end options. Both types will supply air effectively, but pricier models include extra features like balanced first stages and adjustable second stages. For recreational divers who dive ten times a year or less, a $300 regulator is often sufficient. The […]
Surviving in a transparent kayak for 36 hours is a thrilling challenge that combines adventure with marine interaction. The journey takes participants from a stunning coastline to remote islands, where they must live, eat, and sleep in the kayak. Along the way, divers can enjoy spearfishing and meeting various marine life, making the experience even […]

Saturation diving is a unique deep-sea diving method that allows divers to live and work underwater for weeks. In this technique, divers breathe helium or other gases under high pressure, allowing their bodies to become saturated without needing to decompress multiple times. Divers only undergo a single decompression process at the end of their duty, […]
A new crystal made from cobalt could change scuba diving by allowing divers to breathe without tanks. This crystal absorbs oxygen from the air, up to 160 times more than normal, and can release it when needed. This technology could make diving easier by extracting oxygen from the water, potentially allowing divers to leave their […]

Innovations in scuba diving equipment are rapidly developing. Exciting new technologies include tank-less diving systems, like the ORB Oxygen rebreather, and oxygen-absorbing crystals that extract oxygen from water. Advanced dive masks are also being created, such as the Scuba-S mask, which features a built-in camera and communication devices. Virtual reality experiences and underwater simulators are […]
A lobster diver named Michael Packard had an incredible encounter with a humpback whale while diving near Provincetown, Cape Cod. He ended up in the whale’s mouth for about 30 seconds before being spat out. Although this story sounds unbelievable, similar incidents occasionally happen. Whales are generally not threats to divers, but close encounters with […]
