Distinguished by a long tail and advanced wing design, the Super Sub is equipped with a propulsion system with four powerful thrusters that delivers a total of 60 kW allowing for steep 30-degree climbs and dives.
If the name Peter Sotis rings a bell, it is no coincidence. He was Rob Stewart's dive buddy when the filmmaker tragically lost his life on a deep rebreather dive in 2017, after which he was ostracised by the dive community as well as sued by Stewart’s family for his role in Stewart's death. Both the incident and the lawsuit have been covered in the magazine.
Why sharks sometimes bite humans remains unclear, but potential reasons include mistaken identity, whereby sharks are thought to mistake humans for their typical prey; curiosity; hunger; and defensive/offensive aggression.
The mistaken identity theory has received little scientific scrutiny and the visual similarity between humans and pinnipeds at the surface has been debated largely on the basis of human visual perception, rather than that of sharks.
Can hunting by echolocation be as fast as hunting by sight?
As visual animals, we may find this a peculiar question—not so if one applies it to animals that hunt using echolocation, like bats, dolphins and whales. These animals emit clicking sounds and use the reflected echoes to determine the location of objects and other animals.
Can animals that hunt using echolocation lock onto their prey and track their movements, and how fast can they react? These were questions that an international team of researchers sought to answer.
The England-based conference features presentations from around the world on shipwrecks, maritime archaeology and treasure.
There are several possible reasons for this. To get an idea why, we can look to Australia, where the dive industry is still reeling.
In Queensland, the impact of the Covid-19 pandemic has been catastrophic. Before the pandemic, the industry depended highly on backpacker instructors and those with short-term work visas. Australia’s high cost of living and low wages discourages many locals from careers as dive instructors.
Travelling to the Antarctic to dive gin-clear polar waters is a dream topping many an adventurous diver’s bucket list. Farhat “Raf” Jah shares his impressions and experiences from a dive expedition to Antarctica, the Falkland Islands and South Georgia.
It felt a bit surreal heading to the airport again for the first time in almost two years. I used to frequently attend various dive shows, events and conferences and go through the airport as a matter of routine. But that was before the pandemic shut everything down some 21 months ago.

What also made this event extra pleasant was the great food, and that the temperature outdoors was very comfortable and balmy. When compared to so many other conferences, which are often held during late fall or winter in colder and darker regions, being able to sit outside and dine in pleasant temperatures and still be able to walk around in shorts and short sleeves was a real bonus.

As much as 84 percent of the rubbish found on Australian beaches in the past ten years is plastic.
Almost half of all the debris originates from land-based sources (littering, dumping on land, etc), and seven percent from dumping activities at sea.
The remaining 42 percent could not be traced to a specific source as they had broken down into smaller fragments, which would eventually become microplastics.
This was the findings of a study led by University of New South Wales (UNSW) Science, and published in the journal Science of the Total Environment.
Gobies camouflage faster and better when they are alone, compared when they are with another goby.
Why is this so?
According to the findings published in the Royal Society Open Science journal, lone fish tend to be more vulnerable.
