A Different Type of Snow

The word "snow" brings up many mixed reactions from many people. To people who see it a few times a year it has a magical quality, to those you see it many times a year it can become that damn white stuff, but few people when they hear the word "snow" think of the deep-sea. But deep-sea snow does exist!

Don't think that there is only deep-sea snow, there is also snow that occurs in mid-water in the oceans, but that's a story for another day.

Extension Investigation

If you need help scratching a mental itch, use the resources below:

  1. What is deep sea snow composed of?
  2. What characteristics of the enzymes used by vent bacteria make them of interest in industrial and research applications?
  3. How do animals at deep-sea vents depend on this snow?
  4. Where do you find deep-sea vents?
  5. What is the primary source of energy at deep-sea vents?
