My question is about analyzing the data you collect. How will you consider
the significance of yearly weather unpredictability (NG, May 2005) or large
scale physical phenomena (recent NPR report stating that tsunami slighlty
changed earth's rotation rate and axis)? Or what is your reason for
considering them insignificant?

Hi Duncan,

Interannual climate variability certainly has an impact on river discharge and chemical fluxes in rivers. There are also huge changes in discharge and chemical fluxes seasonally. Our approach for dealing with this variability, and understanding it as much as possible, is to collect samples as frequently as possible (each of the six rivers we're working on is being sampled 7 times per year) for as long as possible (we currently have plans to sample for 4 years but hope to be able to continue the project). This should help us to correlate the variability in the rivers with variability in weather or other factors.

In addition to the "natural" variability in the system, we also expect that river discharge and chemical fluxes will change over time as climate changes (ie, as Earth warms). So the samples we are collecting now will be critical for assessing changes in the future.

Thanks for the questions,

Max
