Abstract
This dataset includes redox potential (mV) at 6 different depths from 2 redox probes each at the Maryland Agricultural site (Chrisfield Farm) for the CZNet Coastal Cluster. Redox potential was measured continuously in the field at 15-minute intervals with SWAP Instrument ORP-120-B redox probes installed into the ground. The probes each have 6 platinum electrode sensors that measure soil redox potential at 5 cm, 15 cm, 25 cm, 35 cm, 45 cm, and 120 cm from the ground surface. Each probe was connected to a Campbell CR1000X datalogger with a SWAP Instrument REF-12-0-A Ag/AgCl reference electrode. The reference electrode was installed below the ground surface at a depth that was always in contact with groundwater. The reference probes were installed into capped PVC surrounded by a 3 M KCl gel with holes drilled at the bottom of the PVC for contact with the groundwater. Redox potential values were corrected to the standard hydrogen electrode value by adding +200 mV to the measured potentials. Due to regular replacement of external data logger batteries and data downloads, there may be gaps in the data.
