Thank you Jill, that's some really fascinating research!! I was wondering if you could elaborate a little bit on the geochemistry in the soils/sediments at the meandering bends you show around 7mins into the presentation. Specifically, I was intrigued to notice there being somewhat of an inverse relationship between inorganic and organic carbon. Do you have ideas on the reason for this? Many thanks again, Pieter Bots.

Hi Jill - Congratulations on Urey Medal and thank you for the very interesting talk. I was intrigued by the large difference in community composition on hillslopes versus floodplains that you showed at the end of the talk. Do you have a sense how these differences influence the rate of biogeochemical cycling (I'm particularly interested in organic carbon oxidation)? Do you have any sense how representative your measurements at the East River are for temperate landscapes in general?

This talk was very interesting! I was really interested in the prevalence of sulfur reducing and oxidizing bacteria in the floodplain at the East River. Do you have any thoughts on how we may begin to understand (or even quantify) the role of these redox processes in the watershed sulfate budget? I.e., do you think that a significant portion of the sulfate in the East River ends up getting reduced to secondary sulfides (or otherwise biogeochemically cycled) in the floodplain? Thank you!

Hi Jill, thank you for preparing that very clear and data-rich presentation, and congratulations for the well-deserved Urey medal. My questions are along the same line as Joel's. Can the genome sequencing data be used to determine what parts of the landscape are carbon sinks/sources (i.e. where are the CO2-fixing microbes most active and where are CO2-producing organisms active)? For the meander bend areas, do you have enough data to correlate the spatial patterns in TN, TOC, and TIC with abundances of specific microbial communities?
