The operation, conducted in October 2025 under the international initiative Operation Thunder, began when inspectors in Anchorage, Alaska, uncovered a suspicious shipment of shark fins. This discovery led to a broader investigation, revealing a trafficking route that extended through Anchorage, Alaska; Louisville, Kentucky; and Cincinnati, Ohio. The shipments had originated in Mexico and were destined for Hong Kong. 

A tragic incident in Arizona on 11 July has ignited some public debate and concerns around the safety of hyperbaric oxygen therapy. A physical therapist died following a flash fire inside a hyperbaric chamber at a health and wellness clinic in Lake Havasu City, which was not a medical-grade hyperbaric therapy facility. This is the second such fatality reported in the United States this year. In a similar case, a 5-year-old boy died in February when an oxygen-rich chamber exploded at a Michigan clinic.

Recent changes in US immigration enforcement have prompted updated travel advisories from Canada, Germany, Denmark and Finland. These nations have warned citizens of an increased risk of detention and secondary screening, particularly for members of the LGBTQ+ community and those with non-standard travel documentation.

Diving Talks

We will take them in chronological order. Diving Talks, held in late October, has quietly become one of my top favourites.

Recent research reveals that their numbers in Alabama’s Mobile Bay have risen fivefold over the past two decades, and similar trends have been seen in Texas estuaries like Galveston Bay, according to a new study.

Spearheaded by Jun Ebersole, Director of Collections at McWane Science Center in Birmingham, alongside David Cicimurri, Curator of Natural History at South Carolina State Museum, and T. Lynn Harrell, Jr., Paleontologist and Fossil Collections Curator at the Geological Survey of Alabama in Tuscaloosa, the team named the new species in honour of the late Dr.

The remarkable sighting occurred on 9 July 2023, approximately 400m (1,300ft) off the shores of Carpinteria, California. Wildlife filmmaker Carlos Gauna and Phillip Sternes, a doctoral student in the Department of Biology at the University of California Riverside, stumbled upon the extraordinary sight while filming aerial footage.

In 2015, amidst a marine heatwave, Barott’s team tagged numerous coral colonies, initiating a study on coral adaptability. Their focus: the rice coral (Montipora capitata) and finger coral (Porites compressa), two dominant species in the region. Over the years, multiple heatwaves provided a unique opportunity to observe coral responses, revealing both resilience and vulnerability.

Bret Gilliam was a larger-than-life personality—dare we say, character—in the dive industry. Over a 50-year career, he was involved with several dive-industry firsts, holding a number of influential postings, including serving on the boards of NAUI and IANTD, as well as CEO of TDI. But he was most known for being a co-founder of what would become the largest technical diver training agency in the world, TDI.
