Since April 2015, pH, DO, temperature, and salinity measurements have been taken in 30 min intervals in Mumford Cove, CT, United States. This is a shallow cove that is typical for the area.
This dataset includes records from 14-April-2015 to 04-Feb-2020.
All measurements were made with Eureka Manta Sub2 probes (www.waterprobes.com). The measurement interval was 30 minutes. All measurements were made in Mumford Cove, CT, ~ 0.5m above sandy bottom. Deployment time of each sensor varied between 3-6 weeks, all probes were calibrated prior to deployment for salinity, pH, 100% air-saturated water oxygen. The probe was attached to a local subsurface buoy.
pH: calibrated with 3-point, NIST certified buffers, accuracy +/- 0.1, precision: 0.01, automatic temperature correction
Optically Measured Dissolved Oxygen (HDO): calibrated with 100% air-saturated water
Salinity: Calibrated with FisherScientific Conductivity standard 50,000 uS/cm
QA/QC consisted of identifying and deleting salinity data that ‘jumped’ within a single 30 min interval more than 1 salinity unit.
