Summer and autumn REPLIM field work - 2017

Last summer and autumn we have had a busy time doing field work in the lakes of the REPLIM network.

We have mapped the bottom of the lakes using an ultra light system: a Deeper PRO+ ecosounder with wifi connection to a smartphone for recording geo-referenced depth data. A bathymetric map is drawn in real time.

We use a Ruttner sampler to take samples of the water column from an inflatable boat.

In each lake, we have installed buoys from which the sediment traps and thermistor chains are hanging. The buoys are 0.5 m underwater in order to not to get caught within the ice cover in winter.
