Questions related to Scientific Diving
Acrylic plastic viewports/spheres are often used in submersibles. Jerry D. Stachiw in his book Acrylic plastic viewports presented a experimental spherical (non-conical) viewport design made out of a special type of ceramics that could go deeper (more than 10000m as far as I can remember). What is the present status of the research in this area of transparent materials for non-conical view-ports/spherical hulls ? (Note: question corrected after first answer)
The last developments of the ADS technology (civilian diving) are still within the 350-450 metres range (Exosuit, hardsuit etc.). It is fully known that necessity is the mother of invention, and ROVs are here to stay and for greater working depths they can manage it somehow. However, my question is: Suppose there would be the need for ADS to go deeper say, 1500 metres. Could current ADS technology (Not only rotary joint based movement) answer to this demand?
Recreational and scientific scuba diving are for me insatiable passions. However, it came to my mind that we are currently experiencing a shift in underwater data acquisition thanks to the development of AUV, ROV, surface drones and acoustic methods. This interest is also linked with a shift in my career going from extensive underwater sampling by scuba diving to remote sensing by acoustic methods and the awareness that came with it. So my (heartbreaking) opened question foreseeing the end of the scuba diving era within few decades.
What is your feeling about this?
Which fields see the fastest changes?
Which remote or automated techniques already exist or will emerge?
I've been wondering since a few months ago what do you think is the most important virtue a scientific should have or develop to make impactant or good research? I supose there are a few critical features a scientific cannot rid off before, during and after they start making research for the very first time.
Thanks for answering.
Recently, I collected qualitative samples of marine soft-bottom zoobenthic communities at 10-15 meters depth by skin diving. I used hand-operated corers of 8cm diameter. I wonder whether there is any publication/report/manual on sampling procedures by skin diving.
I have little experience with divers competing in platform and springboard. I am aware of many core exercises that have limited specificity to joint movement in diving, however would like to include some new exercises that are perhaps more specific. I currently prescribe Swiss ball pikes and hanging leg raises (athlete holding onto chin up bar lifts feet towards hands), plus other general core exercises. Does anyone know of a wider range of movements that will target the core muscles in a way similar to the diving movements?
