When it comes to responding to certain computer alarms, can one be too cautious? Being well informed about gas exposure limits and computer defaults can be an advantage. Simon Pridmore discusses a case in point, involving computer nitrox alarms on a routine wreck dive
Advanced Ocean Diver (AOD) is an optional course that gives new divers more choice and flexibility as they progress with their training.
The course is open to all Ocean Divers (or divers who have an equivalent certification from another recognised diver training agency and have also completed Nitrox training) aged 14 and over.
The Advanced Ocean Diver course includes four theory sessions, which can be completed either via eLearning or in person with an instructor, giving flexibility for students and instructors.
Some ocean animals are just inspiring. To be able to glimpse a massive animal like a whale shark can be a lifelong dream that some divers never get to experience. The ocean’s largest living fish inhabits all of the world’s tropical waters, but sightings are usually rare. However, there are a few seasonal hot spots where the likelihood increases.

The first time I went cave diving in Mexico's Yucatán was over 22 years ago. I will never forget how excited I got, swimming through these spectacular passages. I remember thinking this was as close to being on another planet as I would ever get.
The Swedish Coast Guard apprehended the divers in July 2020, as they were found retrieving artifacts from a wreck off the Baltic island of Öland. A subsequent house search uncovered a large number of objects, which were suspected to originate from wrecks classified as protected. Among the objects was an iron cannon dated to the 17th century.
The indictment includes ten charges for incidents during a number of dives that took place from 2013 to 2020. Two of the men stand charged on all counts.
During Buddy Dive Thru the Lens, our photo guru Guillermo will offer a program for guests to develop their skills and knowledge through workshops and presentations and practice their newly learned skills in a perfect environment.
The event will be sponsored by SeaLife underwater cameras. This offers a great opportunity to try the newest SeaLife cameras and products during try-outs and workshops.
For the bona fide traveller, or should I say, the thrill-seeker, the thought of heading off to the far side of the world is enticing. Ponder this for a moment: Have you ever heard of the Marquesas Islands?
A naturally produced melanoma-fighting compound called "Palmerolide A" has been found in a microbe that lives in Synoicum adareanum, a species of ascidian common to the waters of Antarctica's Anvers Island archipelago, where it grows in small colonies.
Ascidians, or "sea squirts," are primitive, sac-like marine animals that live attached to ocean bottoms around the world, and feed on plankton by filtering seawater.
“The wreck is made from oak, cut between 1233 and 1240, so nearly 800 years ago,” said Staffan von Arbin, a maritime archaeologist at the University of Gothenburg.
Last autumn, the University of Gothenburg conducted archaeological diving inspections along the coast of Bohuslän to find out more about known wrecks on the seafloor. It was during this work that the maritime archaeologists came upon the wreck outside of Fjällbacka, which has been given the name “Dyngökoggen.”
The hamlets, a group of reef fishes from the wider Caribbean, sport a stunning array of colours and patterns, but the genetic basis of this morphological variety is unclear.
Although the hamlet lineage is about 26 million years old, the diversification of colours appears to have occurred only within the last 10,000 generations in a burst of diversification that ranks among the fastest in fishes.
Do you worry about the health of this Blue Planet of ours?
Want to explore, but don’t think the price of entry should be major sponsorship, a camera crew, and a public relations department?
‘Time to Surface’ is launching a series of workshops, to explore how communities, organizations and individuals can determine what incentivises better outcomes for themselves and others.

The British Cave Rescue Council
The BCRC is the representative body for voluntary underground rescue in the British Isles. When requested the BCRC will also send qualified, experienced cavers / cave divers overseas to be part of a rescue team. Probably the most high profile rescue the BCRC has been involved with to date, was the Thai cave rescue in 2018.
