This review comes on the coat tails of the other virtual dive show, Scuba.Digital, which we attended a few weeks prior and the conclusions are just about the same; The conference component in which attendees can listen into a range of webinar-style presentations worked reasonably well.

The rest of it, however, such as networking activities which is an essential part and, to entities like ourselves, the most important aspect of taking part in dive shows, absolutely did not.

Coral reefs have been seeking new pastures, as rising temperatures heat up their natural habitats.

Over the last four decades, coral reefs have been progressively shifting their homes from equatorial waters to more temperate regions.

The reason? Climate change.

“Climate change seems to be redistributing coral reefs, the same way it is shifting many other marine species,” said Nichole Price, a senior research scientist at Bigelow Laboratory for Ocean Sciences and lead author of the paper on the topic.

In September 2019, off the coast of California, a fire aboard the MV Conception, a 23-meter (75-foot) scuba diving liveaboard, broke out during the night, killing 33 passengers and one crew member. The captain and four crew members barely escaped. After more than a year of speculations and rumors, the NTSB (the U.S. National Transportation Safety Board) published the results of its investigation and the U.S. Coast Guard issued a new policy on a few topics, including the charging of lithium-ion batteries aboard small vessels and liveaboards.

The paper presents the reasons why large predators of great ecological importance cannot supply the rising demand for shark fins, which is driven by profits that rival the drug trade and involves the fisheries of nations around the globe. They have essentially run out of fish so are targeting sharks now that the shark fin trade has made them valuable.

In one of the largest, most complex underwater archeological undertakings in Canadian history, Parks Canada and Inuit are working in collaboration to explore the wrecks of HMS Erebus and HMS Terror―the storied ships of the 1845 Franklin Expedition that set sail from England on a quest to find the sea route from the Atlantic Ocean to the Pacific through the Arctic Ocean―across what is now Canada's Arctic and Nunavut.

Reef-building staghorn coral (Acropora cervicornis) was abundant and widespread throughout the Caribbean and Florida until the late 1970s.  The fast-growing coral formed dense thickets in forereef, backreef, and patch-reef environments to depths over 20 m.
