Dissolved Oxygen concentrations from Durleigh Reservoir, 2018

This dataset contains Dissolved oxygen concentrations from 2 different locations in Durleigh Reservoir in Somerset, England. Two miniDOT oxygen loggers were fitted with miniWIPER’s and deployed at 2 locations in Durleigh on 30 May 2018. Both sensors were collected on 5 October 2018 and the raw data files are presented in this dataset.

Provenance & quality

Each location was marked with a buoy (A2 size) attached to a 10 kg weight using rope. The miniDOT’s were attached onto the rope near the weight (bottom of the water column) at both locations. Both miniDOT’s were set up to take measurements at 10-minute intervals for dissolved oxygen (% saturation and mg l-1) and temperature (°C)

The first site, labelled location 2, is closer to the artificial mixing devices (surface mixers) installed in the reservoir (60 m away) and deeper, with a water depth of 6 m when the MiniDOT logger was deployed. The second site, labelled location 3, is farther away from the artificial mixing devices installed in the reservoir (435 m away) and in a shallower region, with a water depth of 4 m on deployment. On the 13 June 2018 and 21 August 2018, both miniDOTs were brought to the surface to change miniWIPER batteries and remove any fouling from the sensors. Nevertheless, there were periods during the 2018 deployment where the sensors were fouled, and dissolved oxygen measurements were reading 0% saturation.
