released before the air pressure inside and outside reach equilibrium. So some of the small pieces of paper or some other pieces of trash created during the previous two days were pumped out by the air pressure.
or probably some air leaking from the instrument. You can see the "bubble" quickly expanded and disappeared.

It does not look like a shot captured in the water. I am a veteran diver and served in the UDT in the Korean navy for 12 years. Those objects are not bebbules. Bubbles in the water don't move like those in this vedio. In the water, bubbles move slowly in the begining and then get speed. And if the bubble is generated by breathing, it will move forward and go up as well.
as for the snow,
Snowflakes, the basic unit of snow, originate as tiny ice crystals within "cold clouds." Cold clouds are clouds that exist within air that is at, or below, the freezing point. As an ice crystal is blown back and forth between the top and bottom of the cloud, it grows in two ways: by coalescence and by deposition. In coalescence, the ice crystal collides, and sticks to the cold water droplets it encounters in the cloud. In deposition, water vapor molecules (particles made by the combination of two or more atoms) within the cloud freeze directly onto the ice crystal.
As the ice crystal grows, it bonds with other ice crystals and takes on the six-sided shape of a snowflake. When the snowflake becomes heavy enough, it falls to the ground.
