Mayfly Monitoring from Mountains to Estuary

Hi all,

I am planning to deploy a network of Mayfly stations to better understand where and when contaminants are mobilised within a catchment. I am working on a base set of sensors that consists of a decagon CTD, and a turbidity sensor (probably YOSEMITECH).

The catchment feeds into a highly valued estuary which has become degraded due to excessive land use. The community group that I am working with would like a monitoring ‘buoy’ in the estuary to couple with the Mayfly catchment network that I am proposing.

I figure that I could easily provide a Mayfly solution to the monitoring buoy, which is likely to be cheaper and allow for more monitoring locations. My plans are to hammer a long pole into the estuary bed and attach a Mayfly station.

Has anyone attempted anything like this before?

Are there any thoughts on a sensor set-up to track fluxes from the catchment? Obviously conductivity is not going to be that useful due to salinity, so I might need additional parameters.

Any other advice?

Thanks for your time.

James
