Whales dive to get food. They come back to the surface to breathe.
Slowly
Removing the air from your lungs makes you less bouyant and allows you to sink faster. I never exhale when doing a surface dive so I can swim down deeper, if you do the surface dive properly by throwing your legs high out of the water you will sink fast enough.
The process of a submarine to move from the surface of the ocean to a position underneath the surface is called a dive. This is accomplished by allowing water to fill the tanks of the submarine, the heavy water pressure now inside the vessel now will force it to sink below the surface, thus a "dive".
1. Dive within your limitations. 2. Relax while you dive. 3. Have positive buoyancy at the surface.
No but they give you added buoyancy.
If your first dive is to 60 feet for 50 minutes, you should refer to a dive table or computer for no-decompression limits, which typically allows for a maximum dive time of around 55 minutes at that depth. After spending one hour and 40 minutes on the surface, you have effectively re-gained some of your allowable dive time, but the exact adjusted maximum dive time would depend on the specific dive table or computer used. Generally, after such a surface interval, you may gain back around 10-15 minutes of dive time, but it's crucial to consult your dive plan for accurate limits. Always prioritize safety and adhere to the guidelines provided by your dive training agency.
Dive in front of the city. their is an opening in the dive spot. enter and go up to the surface. you are now in the city. :)
Crocodiles don't generally dive, the slide into the water from a bank and swim close to the surface to break for air.
diver's short name or code for your 'average' dive trip on a dive boat - 2 dives, each separated by an approximate 1 hour SIT (Surface Interval Time), usually on 2 different dive spots.
