According to CAS’s Matt Wandell the chamber is fairly simple in design and can bring a fish up to to surface pressure in around 20 hours or so without adverse effects.

Aside from burst swim bladders, fish, like humans, can also get decompression sickness when exposed to rapid changes in pressure during capture.

“Bent” fish are most likely widespread in the live reef fish trade, as most of the species that have been examined were found to suffer symptoms of decompression sickness after capture from shallow depths of 10 to 15 metres.

A new study in the journal Plos One has revealed blue whales assemble for long periods in the busy shipping lanes off California, raising concerns about collisions between vessels and the endangered cetaceans.

“It’s an unhappy coincidence,” said study leader Ladd Irvine, a marine mammal ecologist at Oregon State University. “The blue whales need to find the densest food supply. There’s a limited number of those dense places, and it seems as though two of the main regular spots are crossed by the shipping lanes.”

According to new research, offshore wind farms may become seal hunting grounds. Although the long-term environmental impact remains in question. Located offshore, wind farms are banks of wind turbines that harness the wind's energy to produce electricity.

"If you're going to be a member of the Jet Set and fly off to Katmandu for coffee with King Mahendra," wrote Horace Sutton in the Los Angeles Times, "you can count on contracting Jet Lag, a debility not unakin to a hangover. Jet Lag derives from the simple fact that jets travel so fast they leave your body rhythms behind."

David Millin, Managing Director of Sea & Sea stated, “TDI is a legendary agency that UK divers and instructors have trusted for years to provide top notch training and quality materials. Sea & Sea is excited to be part of the continuing history”.

Brian Carney, President of International Training, acknowledged that the UK diving scene has an interesting history when it comes to TDI. The late Rob Palmer, a much respected cave explorer and a leading light in the fledgling technical diving community, helped set up TDI twenty years ago.
