Exiting the Water

Diving requires proper planning and equipment maintenance, including your body. In the final minutes of a dive, a tired diver must swim to the boat, climb a ladder, and haul gear onto the deck.

The Sargassum Surge

On a calm day, a mat of golden-brown sargassum can look like a tangle of seaweed riding the surface.

When Time Matters

Remote diving requires self-sufficiency. From expedition liveaboards to offshore technical projects, divers operating beyond cellular network coverage understand that preparation, training, and redundancy are essential for safety.

Advancing Dive Safety Through Collaboration

DAN welcomed senior leadership from the U.S. Navy Experimental Diving Unit (NEDU) to its Durham, North Carolina, headquarters for a day focused on dive medicine, research, and exploring opportunities for closer collaboration.

Anilao is home to more than 25% of all nudibranch species worldwide. Some are as small as a grain of rice, while others — like this massive Miamira alleni sea slug — can reach up to 5 inches (12.7 cm) long. I was able to capture the slug’s fine details and incorporate the rich morning sunlight by using a wide-angle macro shooting style.
