ABSTRACT:

This Collection Resource contains data for the Coastal Critical Zone cluster from the Monie Bay site. Monie Bay is a Maryland Forested site and is located in Princess Anne County, MD within the Chesapeake Bay National Estuarine Research Reserve (https://dnr.maryland.gov/waters/cbnerr).

ABSTRACT:

This Collection Resource contains data for the Coastal Critical Zone cluster for the Milford Neck site. Milford Neck is a Delaware Forested site located in Kent County, DE and managed by the Delaware Department of Natural Resources and Environmental Control Division of Fish & Wildlife (https://dnrec.maps.arcgis.com/apps/MapSeries/index.html?appid=095bbc32f0104b288669c42caee3373e).

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. This work was conducted on private property with the cooperation and trust of landowners and farm operators who have requested to remain anonymous. We have removed select coordinates and information that could be used to identify their operations.

ABSTRACT:

This dataset includes redox potential (mV) at 5 different depths from 2 redox probes each at the Virginia Forest Site (Brownsville) 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 5 platinum electrode sensors that measure soil redox potential at 10 cm, 20 cm, 30 cm, 40 cm, and 115 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.
