GREON Mission and Strategy• Mission:

– To advance the science and understanding of large‐floodplain river ecology by collecting and sharing high resolution data on key water quality parameters with scientists, managers, and the general public.  

• Strategy: – To work with partners from academic institutions, government agencies, and NGOs to create a global network of identical water quality monitoring platforms that will be deployed both in fixed monitoring locations and in mobile/short term research deployments.

Periodic Problems

• Inadequate Power during short, overcast days.• Moisture/water in sensor housing.

– Wave action (large reservoirs)

• Dirty optics on SUNA nitrate sensor.• Loss of communication with sensors• Debris damage• Unattached from anchor; “absconding”

Page 22: Great river ecological observatory   sloan

Future Directions

• Move Cape Girardeau buoy to side channel• Install fixed station in Alton, IL• Collaborate with YSI to test new sensors• Proposal submitted for work in Saskatchewan• Maintain quality data and continue to adapt to new research needs
