Advanced SCUBA Skills for Scientific Diving

Semester 1

This course have an extra cost, is not included on the tuition fee!


This course is designed to train students in advanced SCUBA dive skills, such as stability, team work, problem solving and situational awareness, through  well structured dive planning and strong academic knowledge on gas properties and hazards, gas strategies and management, decompression and adequate equipment use for scientific diving activities. 

An international certification, according to norm NP EM 14153-02, may be awarded through an additional training module.  

The class program will be focused on:
Theory component:
a) Physics and physiology:

  • Gas laws
  • Gas properties
  • Gas Toxicity (O2)
  • Hipercapnia
  • Gas poisoning (CO2)
  • Narcosis
  • Use of Helium 

b) Gas management 

  • Calculating appropriated gas supply and gas types for scientific research 
  • Calculating adequate gas reserves 
  • Dive gas and decompression gas
  • Gas rule of half’s and rule of thirds and its application in to scientific diving 

c) Decompression theory

  • Bulman algorithm versus VPM for decompression
  • Dive computer, dive tables and software 
  • Minimum decompression profiles 
  • Emergency decompression
  • The use of enriched gases for decompression acceleration

d) Scientific diving planning 

  • Teams
  • Task assignments 
  • Situation awareness 
  • Risk assessment 

e) Scientific Diving SCUBA equipment
Practical application:
a) Underwater stability (buoyancy mastery, trim, balance)
b) Propulsion methods adequate for silty and fragile environments (frog, flutter, modified frog, modified flutter, helicopter turn, backward)
c) Basic manipulation and operation of regulators (including back up) and masks
d) Underwater tank valve manipulation 
e) Use of safety buoys
f) Team position and problem solving 
g) Managing out of gas situations
h) Managing adequate ascend profiles, including minimum decompression while sharing gas to an out of gas diver.
i) Underwater data acquisition on a pre-set monitoring site. 

This class as an entry level prerequisite for students which is to have an Open Water Diver certificate. 
If students successfully pass the class, an international certification is awarded.
