You are trapped 100ft underwater. You have an oxygen tank with 10 minutes worth of air. The problem is, it is stuck in the ground so you cannot swim with it. How do you survive?

Until help arrives...

1. Assess the Situation: Stay calm and assess your surroundings and available resources. Understand the depth, terrain, and any potential hazards.

2. Look for Alternative Sources of Air: Search for air pockets or potential sources of air within the underwater environment, like underwater caves, crevices, or any structure where air might be trapped.

3. Signal for Help: If possible, use any signaling devices you have to attract attention. This might include banging on your tank or any nearby objects to create noise.

4. Conserve Oxygen: Conserve your oxygen by breathing slowly and deeply. Avoid unnecessary movements to minimize oxygen consumption.

5. Attempt to Retrieve the Oxygen Tank: If the tank is stuck, try to dislodge it using any tools or equipment you have. Use your surroundings to create leverage or mechanisms to free the tank.

6. Use Equipment Creatively: Utilize any available equipment or tools to devise a way to transport the tank. If you can't swim with it, perhaps you can use a rope or another object to fashion a makeshift sled or drag the tank along the seafloor.

7. Escape to the Surface: If you can't retrieve the tank, consider making your way to the surface. Ascend slowly and with caution, making safety stops as needed to prevent decompression sickness.

8. Minimize Exertion: Swim slowly and steadily to conserve energy and oxygen. Panic and rapid movement will increase your oxygen consumption.

9. Practice Breath Holding: If you have any experience with free diving or breath-holding techniques, utilize them to extend your time underwater before needing to breathe from the tank.

It's important to note that attempting any actions in an underwater or survival scenario should be done cautiously and with proper training and equipment. If you find yourself in a dangerous situation, seeking assistance from trained professionals and following safety protocols is crucial.
