With its unique compact design (about the size of a 16in MacBook Pro), this underwater scooter is portable, conveniently fitting into a carry-on bag.
Designed with the most demanding divers in mind, this German-engineered wetsuit is easily donned and doffed, with zippers and seals at wrists and ankles, and has shoulder and knee protectors integrated into the suit, which do not hinder flexibility, states the manufacturer.
Drone footage of marine mammals helps us better understand their behaviour and social structure or simply provides us with some stunning footage we couldn't obtain otherwise. However, drones can also affect whales, dolphins and other mammals if flown too close.
So what is too close and what are safe distances?
According to a press release from the Great Lakes Shipwreck Historical Society (GLSHS), on Nov. 18, 1914, the Steamship C.F. Curtis was towing the lumber-loaded, schooner barges Selden E. Marvin and Annie M. Peterson from Baraga, Michigan to Tonawanda, New York. They were carrying more than 3 million board feet of lumber.
As fans of crime series will know, every living creature sheds DNA through skin cells, hair, scales and other bodily secretions as they move. This leaves behind a trace in whatever environment they were in, thus becoming environmental DNA (eDNA).
An emerging molecular technique called eDNA analysis enables researchers to scan samples of water, air, or soil for tiny remnants of DNA and identify organisms it came from.
The project will promote underwater cultural assets and target tourism development by using a multidisciplinary approach to present and document the shipwrecks, navigation routes, harbours, anchorages, and other archaeological sites along the Montenegrin coast.
If you have ever wondered how dark the earth was before humans discovered fire, then spend some time in the forest. The night arrives shortly after 6 p.m. and the sun rises around 5 a.m. In this period of time, you may feel enveloped by the darkness in this part of South Africa. Andrea Murdock Alpini shares his adventure diving the Komati Springs.
Known only to few divers, a hidden treasure in Taiwan is Orchid Island, a remote and rugged outpost of volcanic origins located far from the tourist crowd, offering sublime diving for the curious adventurer who is not afraid to go off the beaten path. Simon Pridmore has the story.
How did some of the advanced technologies we use as divers today come to be? Simon Pridmore takes an intriguing look into the early days of rebreathers with an excerpt from his new book, Technically Speaking—Talks on Technical Diving, Volume 1: Genesis and Exodus.
Genomic data reveals historical population declines and high levels of inbreeding in great hammerhead.
In a recent report by the IUCN Red List of Threatened Species, 31 percent of all shark species are threatened (Critically Endangered, Endangered or Vulnerable). In 1980, only 9 species of oceanic sharks and rays were listed as threatened.
Last summer, the highly contagious strain of avian influenza, that was first detected in early winter 2021, had been spreading through North American birds made its way into marine mammals, causing a spike in seal strandings along the coast of Maine.
In June and July 2022, more than 150 dead or ailing seals washed ashore, a number that was approximately three times the normal rate for this time of the year. Of the 41 stranded seals tested for the virus, nearly half tested positive.
