Question

1. What were the first deep-sea divers interested in?

Answer 1

Answer:

1)  William Beebe and Otis Barton were the first humans to reach the Deep Sea when diving in the so-called Bathysphere, made from steel. They reached a depth of 435 m (1,427 ft), where they observed jellyfish and shrimp.

2-3)Diving poses two major challenges for air-breathing animals: hypoxia (a shortage of oxygen) and hyperbaria (high pressure at depth).

4)The Newtsuit is constructed to function like a 'submarine you can wear', allowing the diver to work at normal atmospheric pressure even at depths of over 1,000 feet (300 m). Made of wrought aluminium, it had fully articulated joints so the diver can move more easily underwater.

5)scuba diving is one of the easiest to learn. While you're gliding around enjoying the underwater sights, you're engaged in only three basic skills: floating, kicking and breathing. ... The necessary skills are not tough for most people to master.
