New events can be a challenge for everybody cause there are no precedents and you don't really know exactly what to do. Water Quality used to be around, since there are past tests from 2001, so it might be a bit easier to get to know what to do.

Can someone help me find information (life cycle, reproduction, appearance) for "gilled snails?" They are the only organisms that I can't find much information on.
EDIT: I also need information for water mite.

Google it or go check out a book at a library near you ;)

Question: when you say 1percent salt water is it measured in moles or weight?

Nutrient cycling is the movement of nutrients throughout nature.

I think it is measured based on saturated solutions. For example, 100% salt water would have the maximum amount of salt possible dissolved in whatever amount of water. 1% salt water would be 1/100 of that amount. Since 100g of Water at 0 deg. C can hold 35.7g table salt at maximum, 1% salt water would have .357g. I might be wrong tho :P

Do you guys think it's likely they will ask questions about immature forms of organisms(non-national level)? Cause I mean, just knowing the the adult forms plus their habits, ecology, life cycles and whatnot is plenty already.....

Yes, you will need to know all about the organisms. Identifying what they look like at different stages of life etc..

btw does anyone know what "aquatic chemistry" means...like is it just chemical properties of water or is it something more than that?
