Shore Thing

September 7th, 2013

In ancient Rome the priests of the day would tell tales of the God of the sea, Neptune; the bringer of the tides & all his might. But what about the poor old man in the moon? I’ve written previously on the tides & the moon before for the Go Pro SSI website but I [...]

Back to the SoD this episode boys & girls, in this edition of the GPS Uber-blog we’ll be having a quick peek at Deep-Diving’s-Delectable-Dandy: Dalton. Dalton’s Law of partial pressure states: In a mixture of gases, the total pressure of the mixture equals the sum of the partial pressures of the individual gases. Dalton’s Law [...]

When I was but a pup of a scuba-doo, I was given a great way of remember all of the gas law’s pertinent to diving as covered in the Science of Diving, often referred to by newbie Divemaster trainees as “SoD’s Laws”. The “cheat sheet” to help you remember the laws is based around each [...]

Longer, Not Harder

December 27th, 2012

In our previous post we looked at how we could increase our time underwater by increasing our buoyancy skills, leading to less efforts & lower Surface breathing Rates (SBR). Of course, some may say you can always put a bagger tank on your back. You’ll most definitely need Perfect Buoyancy if you’re continuously changing tank [...]

Suck!

August 1st, 2012

Sweet lordy-lord it’s Science of Diving  (SoD) o’clock again! The way I like to teach the SoD is taking all the technical information given by the manual & putting into practical application. We can use all the equations we want with all the measurements of depth, weight & volume given to us but sometimes we [...]

The Tide Is High….

July 25th, 2012

Building on the previous posts in our Science of Diving category I was recently presented with a Divemaster candidate stumped on a question in the SoD exam. Divers new & old can sometimes get lost in the nomenclature of diving & when divers go on about diving “the slack”, they’re often referring to the tide. [...]

Building on my previous blog concerning the Science of Diving, I’ve asked to expand on some of the subjects found in the program; of course I’m not handing out an answer key, just helping to clarify a few things. Section five of the program; The Aquatic Environment contains many topics including Scuba Oeanography, Taxonomy & [...]

May 24th, 2012

The Physics section of the SSI Science of Diving (SoD) Specialty contains many subjects which truly fulfill SSI’s Diver Diamond philosophy of proper knowledge; the principles of physics, measurements & conversions, gases related to diving & amongst other subjects, gas laws. Physics is defined as; the branch of science concerned with the properties of matter [...]
