Short answer: NO!
Long answer: On TV, you may have seen people use small tanks in this way. These little tanks do exist, and are used by Scuba divers as emergency or backup air supplies. These little tanks are usually about a foot long and have an attached mouthpiece to breathe from.
So why did I say you can't use one snorkeling? Snorkeling involves breathing through a tube on the surface, and then holding your breath while diving underwater. Breathing air from a compressed tank of air while underwater, and then holding your breath can result in SERIOUS INJURY and possibly DEATH!
This is a matter of physics and has to do with the fact that pressure changes as you go deeper and shallower in water and how that affects the volume of the air trapped in your lungs.
If you are not holding your breath, but are breathing continuously from the tank, you are not snorkeling, you're scuba diving.
If you want to be able to stay on the bottom and explore, even if only at a shallow depth, you should really get scuba diving training. The training will teach you about all of the risks involved with breathing compressed air and how to do so safely.

Francisco Pizarro was looking for gold and other valuable resources.
Europeans were motivated to explore and settle in the Americas due to factors like the desire for wealth and power, the search for new trade routes, the spread of Christianity, and the need for resources such as gold, silver, and land. The prospect of finding new territories and expanding their empires also drove European exploration and colonization in the Americas.
