The deepest dive on scuba [Ocean

The deepest dive on scuba [Ocean | Men] took place off Dahab, Egypt, when Egyptian Ahmed Gabr dove to the record depth of 1,090 feet (332.35 m) on September 18, 2014. Time to descend to 1,100 feet (335 m) was 14 minutes but the actual depth was adjusted to 1,090 feet (332.35 m) due to a bend in the line caused by current. Time to ascend was 13 hours 36 minutes, including 7 hours from 89 feet (27 m) to the surface, for a total duration of 13 hours 50 minutes. The planned depth was actually 1,148 feet (350 m) but Gabr stopped at 1,100 feet due to the effects of high-pressure nervous syndrome (HPNS). The dive, which began at 10:30 a.m. on September 18, 2014, and ended at 12:20 a.m. on September 19, required 92 tanks filled with various breathing gases including air and different mixes of nitrogen, oxygen and helium (Trimix).

Underwater Restaurants:

Divers visiting the Maldives now have three underwater restaurants to choose from, including the world’s first all-glass underwater restaurant, the world’s largest underwater restaurant, and the world’s first underwater nightclub that was recently converted into… a restaurant! The Ithaa Undersea Restaurant at the Hilton Maldives Resort & Spa is 16 feet (4.9 m) below sea level and offers 270° views of reef and marine life. It opened on April 15, 2005. The 5.8 Undersea Restaurant at Hurawalhi Island Resort (Lhaviyani Atoll) is 74 feet (22.5 m) long and it weighs 410 tons. The underwater restaurant with a seating capacity of 24 diners was installed at a depth of 19 feet (5.8 m) in 2016. Subsix at the NIYAMA by Per AQUUM resort was formerly a nightclub launched in 2012. It is located 20 feet (6 m) below the surface and 1,650 feet (500 m) from shore under the resort’s overwater restaurant.

World’s Largest Octopus:

Giant Pacific Octopus can grow to amazing size – Seattle Aquarium

Washington State is home to the world’s largest octopus. The giant Pacific octopus (Enteroctopus dofleini) has an average weight of 50-88 lbs (23-40 kg) and a maximum weight up to 600 pounds (272 kg). It can reach lengths up to 24 feet (7.3 m) from opposing arm tips. Enteroctopus dofleini only lives 3-5 years in the wild. Mature females have 2240 suckers (280 per arm) that are used for grasping prey and to move around. The giant Pacific octopus is also frequently observed in shallow water by divers in British Columbia, the state of Alaska, and the Pacific coast of Russia. When left unmolested, it poses no risk to humans. There are approximately 300 different octopus species in the world.

Most Continuous Bubble Rings:

In other record news, Ettore Pozzo (Italy) has set a new world record for the most continuous bubble rings on a single breath of air. Ettore produced 43 continuous and perfectly formed bubble rings on a single breath of air on November 24, 2017. The record event took place in the world’s deepest dive tank in Montegrotto Terme, Italy. In order to qualify for a record, each bubble ring must reach the surface intact before bursting. The Y-40 dive tank, located at the Hotel Terme Millepini, is 131 feet (40 m) deep. It is filled with 1,135,939 gallons (4,300,000 litres) of chemical-free thermal water kept at a constant temperature of approximately 91°F (33°C). The pool includes platforms, caves and a transparent tunnel for pedestrians. The pool was officially opened on June 5, 2014. The letter “Y” stands for the pool’s vertical axis while “40” is its depth.
