Brazilian food and dinner with mentor Peter Cheimets and his wife

-Major Points of Discussion
         -How far can you push deforestation before it starts affecting the water cycle and therefore the rest of the forest?
         -Water's contribution/interactions to overall project
         -River ways as alternate transportation means
         -Human effects on rivers
         -"Unorthodox" ideas, ie. Cutting down trees to test rates of deforestation
 ***What is our solution?  When can we say that we are at a stopping point?

3 October 2002
Asked Mentor Peter Cheimets question, regarding differentiating between human effects and natural cycles.  His answer, and something to keep in mind:

   o first, is it possible to say important things about the relationship between the changing (cycling?) hydrologic conditions of the Amazon basis, and
 man's behavior in the Amazon basin without understanding the starting conditions (ie what was the world like before we messed with it),

    o Is the record conditions what you are looking for (ie "the worst on record") or a drift in the average conditions. Looking at global warming research,
 they spend a lot of time looking for early conditions, but they are also looking a changes in trends (think about the following: if the warmest day ever
 was in 1632, would this mean there was no global warming),

   o Finally, this is an important lesson underlying the class assignment, "What happens when the standard scientific approach breaks down, how do you
 proceed?" (Standard method: compare control situation to one with a single measured change)

Revised Objectives of the Water Systems group

     Rain 6 will:
     1. Research and analyze data from previous papers (e.g. rainfall reports, chemical composition of water etc.) associated with the Amazon Basin's water
     ecosystems.  Then, we will proceed to characterize these water systems which, among other tasks, will require us to consider the effects of
     deforestation and integrate information from various geographical regions within the Amazon Basin region.

     2. Analyze the outflow, inflow and water storage mechanics of the Amazon water system as a whole, in terms of several variables such as evaporation,
     precipitation, transpiration, filtration, absorption etc. and develop a model based on what our research will yield in terms of these components of
     the water cycle.

     3. Identify and devise ways to monitor the water chemistry and chemical composition of the sediments of rivers, lakes and other water systems in the
     Amazon Basin.

     4. Examine the effects of seasonal variations, human development, and general environmental changes on the water ecosystem.  We will also research the
     role of water on other systems of the rainforest.

     5. Collaborate and communicate with other teams and define the way we will be interacting with them in topics that will require involvement by both
     (or more) groups. For example, the study of the diversity of water organisms will require our collaboration with the flora and fauna groups.

Objectives of the Water Systems Group, as defined on 19 September 2002:

1. Research and analyze past data from the Amazon Basin's various water ecosystems.  Characterize these water systems, taking into account the effect deforestation has had on them.  Compare water systems from various geographical regions from the Amazon Basin region.
2. Analyze the outflow, inflow and storage of the Amazon water system as a whole, in terms of evaporation, precipitation, transpiration, filtration, absorption, etc.
3. Identify and monitor the chemical, sedimentary and mineral composition of the water in the Amazon Basin water systems.
4. Examine the effects that environmental and evolutionary changes, seasonal variations and human development have on the water ecosystems.  Analyze the effects that water has on other ecosystems in the rainforest.
5. Collaborate and communicate with outside groups, in order to understand the interactions between them.  For example, we will need to identify certain organisms that live in the water and may give us indications of the biochemistry of the water.  In order to do this, we will need to consult the flora and fauna groups.
My role:  Learn about effects of environmental and evolutionary changes, seasonal variations and human development on water ecosystem; Effects of water on other ecosystems in the rainforest
