The SSI Science of Diving program provides you with an in-depth study of diving physics, diving physiology, decompression theory, the aquatic environment, and diving equipment. This program is a requirement for any diver interested in following the path to Divemaster, Assitant Instructor, or Instructor. This course is also a great opportunity for any diver interested in having a better grasp of what is happening in the diving world around them. Whether you wish you could better calculate how long a cylinder will last at a certain depth, how to find and identify various species more readily, how to deal with a decompression emergency, or maybe just some tricks on how to change o-rings quickly, this course will teach you all of that and more. Find more specific descriptions of each concentration below.

Physiology

Diving causes several physiological changes in the human body. Our physiology workshop focuses on all those changes that we need to be aware of so we can execute our dives safely. In this part of the science of diving program we will review the effects that increased pressure has on the body, potential risks associated with that and how to prevent, mitigate, or provide first aid or treatment for any associated conditions.

Decompression

Decompression is possibly the least understood concept in scuba diving for most newly certified divers. But perhaps even stranger, most divers don’t realize how little they know about this condition. Decompression has been a limitation all divers need to manage since the development of Scuba so many decades ago. One of the areas of knowledge that has changed so little over time is still one of the most misunderstood. Come find out the difference between DCI and DCS. How DCS became known as the “Bends” and the best techniques available to help avoid it. Our Decompression Workshop will teach you everything you want to learn about the theory and more!

Environment

The ocean is, in fact, one of the most fragile resources we have. Understanding the underwater environment teaches us how to interact with the very thing we dive to see. Proper diving techniques and conservation practices are how divers can do their part to protect the future of the oceans. Learn about the cause and effect of ocean waves, wind, tides, ecology, species, and conservation. All the while learning how it can affect divers entries, exits, and time in the water.

Equipment

Don’t lose a single dive to minor equipment problems. Learn how to perform field repairs on your equipment and the proper care that it should have on a regular basis. In this course, we will cover basic and advanced operations, as well as field maintenance of regulator first and second stages, gauges, computers, low-pressure hoses, masks, fins, wetsuits, BC’s, hoses, tanks, lights, and more. We also discuss the history of scuba for full comprehension of product development and the future of design.

Physics

There are many questions that come up for divers after the certification program. How do dive computers change when diving at altitude? How does a digital gauge measure depth as I descend? Why does my buoyancy feel so different at 60 feet than at 30 feet? Why doesn’t my tank change pressure as I descend if pressure is increasing? How do 2 different sized tanks both hold 3000 psi of air? How does nitrogen on gas rates really change with depth and do deeper dives really make me more likely to get “bent”? These are all legitimate questions to have as certified divers. The Diving Physics Workshop explains these issues and also covers more practical aspects of diving. Feel free to bring any other questions you may have to class.

Before Class

  • Minimum age of 10 (Recommended age of 16 due to advanced math requirements)
  • There is no requirement for certification to take this program though you must be enrolled in a certification course

This course is completely dry so the only equipment you’ll need is a pen and paper and an A+ go-getter attitude!

  • All academic sessions and online training
  • Science of Diving final exam with a passing score of at least 80%
  • Maximum of twelve (12) students per instructor

Divemaster Upgrade

The SSI Divemaster rating recognizes that you have the knowledge and training necessary to perform the duties of a certified assistant. These duties include assisting SSI Instructors in conducting entry-level and continuing education scuba training programs. The additional training needed for a Dive Guide to upgrade to Divemaster is simply to complete the Dive Guide program. The SSI Dive Guide program provides you with the knowledge and training necessary to supervise and guide certified divers on recreational scuba dives. The Dive Guide program is an introduction into the world of dive professionals. As a Dive Guide, you will be qualified to lead certified divers on a variety of scuba diving adventures. You will be in charge of safety, management, be able to help other divers with minor gear problems, and be able to lead dive excursions safely whether it be from shore or in the water. The goal is to create well-prepared, versatile and marketable Dive Professionals.

 

As a Science of Diving candidate, you can enroll in both programs concurrently to expedite the training process and potentially save money. Certified Divemasters carry all of the same qualifications as a Dive Guide plus you can:

  • Act as a certified assistant for all SSI recreational courses
  • Assist during open water training dives by taking no more than two (2) students at a time on excursion dives
  • Qualify as a Training Specialist for the SSI Ecology Specialty programs
  • Enroll in an SSI Assistant Instructor and Instructor Training Course
