Isotta dive mask

The Isotta transparent dive mask has been specifically designed for photo shoots with underwater models. It features a large, retro-style, single-lens design, which makes it easier for underwater photographers to get enhanced or highlighted eyes and facial features of underwater models.

Baby loggerhead

Do young loggerhead turtles swim or drift?

Despite good swimming abilities, juvenile loggerhead turtles are thought to drift passively for a significant portion of their existence on the high seas

However, a study by researchers from National Oceanic and Atmospheric Administration has found that turtles were swimming against the prevailing current in a statistically significant pattern at a rate of 30 cm/sec, which indicates an ability to detect the current flow and orient themselves to swim into the current flow direction.

This study provides (...) compelling evidence that these turtles are able to resist such transport using some mechanism not yet fully understood.

Migrating humpback whales have poor health on return journey

Every summer, East Australian humpback whales migrate from the feeding grounds in Antarctica to their breeding grounds in the Great Barrier Reef. They remain there for about several months, before making their way around the southern Australian coast back to Antarctica for the winter.

Indonesia's Banda Sea

Diver with mushroom leather corals, a purple sea fan and orange soft corals on the reef at Hatta Island.

Five minutes into my first dive in the Banda Sea, I came face-to-face with a scalloped hammerhead shark, gliding effortlessly in its underwater realm as it emerged from the depths to investigate the alien visitors descending from above. A second hammerhead swam past a moment later but was less bold in its approach and quickly disappeared back into the abyss.

Retouching Underwater Images

Image 2. Problem zones can be identified (red circles) by zooming into an area of the tutorial image.

It should not happen but sometimes it does anyway: those annoying little white dots in our underwater images, which detract from the overall impression of the photograph. Known as backscatter, these dots appear when small particles in the water reflect the light from a strobe. The more directly the strobe light hits a subject, the higher the risk of backscatter. That is why a strobe should not be pointed straight at a subject.

Japan's Miyakojima

Year 2020. The coronavirus pandemic has confronted the world with an unprecedented situation. Many countries went into lockdown, and as a result, many people were forced to stay indoors, including myself in Japan. Although Japan never went into an official “lockdown”—it instead went into a so-called state of emergency—I could not wait to get out of the Tokyo metropolis as soon as restrictions were lifted.

Max with Joelle Raabe at DEMA show where he tirelessly represented Papua New Guinea for many years

International dive community mourn the loss of Max Benjamin

Don Silcock:

I met Max for the first time over 20 years ago – in the domestic terminal of Port Moresby airport where we were waiting to board a flight to Kimbe Bay. The trip leader introduced him as “this is Max, he’s the owner of Walindi” which was where we were going to.

My first impressions turned out to be pretty accurate… before me was a man who would look you straight in the eye and quickly understand your intent - no BS with Max, he seemed to be able to read you like a book!

Car tyres are a major source of ocean microplastics

Tyres a major source of ocean microplastics

A new study conducted at the Norwegian Institute for Air Research suggests wind-borne microplastics are a bigger source of ocean pollution than rivers, the route that has attracted most attention to date.

Airborne transport has received much less attention than rivers because only the smallest particles can be blown by the wind and their size makes them difficult to identify as plastic. The scientists concentrated on fine tyre and brake dust as there is better data on how these are produced than tiny microplastics from other sources, such as plastic bottles and packaging.
