Temperature, pH, DO, and salinity data from Mumford Cove, Connecticut, USA from 2015-2022

Abstract:

Despite their importance for research and environmental protection, there's still a shortage of high quality and high-resolution temperature, pH, and oxygen data particularly in shallow coastal habitats. We monitor five important environmental parameters (i.e., depth, temperature, salinity, pH, and dissolved oxygen) at 30 minute intervals in Mumford Cove, CT (41 degrees 19'25"N, 72 degrees 01'07"W), a small (2 km N-S × 0.5 km E-W), shallow (1-5 meters), cone-shaped embayment opening to northeastern Long Island Sound, with protected marsh habitat along its western side, marsh and beach habitat along its eastern side, and an extensive seagrass (Zostera marina) cover. Continuous monitoring is achieved by swapping identical and recalibrated probes (Eureka Manta Sub2) every 3-5 weeks.

Description

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 April 14, 2015 to December 9, 2022.

Methods & Sampling

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, ~ 0.5 meters above the 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

Data Processing Description

Data Processing:
QA/QC consisted of identifying and deleting salinity data that 'jumped' within a single 30 minute interval more than 1 salinity unit. pH was corrected for linear drift, using the post-calibration offset.

BCO-DMO Processing Notes:
Version 1:
(version 1 includes data from April 2015 to June 2016)
- reformatted date to yyyy-mm-dd; added date/time column in ISO8601 format;
- replaced spaces with underscores in the location name;
- filled blank cells with "nd" ("no data").

Version 2:
(version 2 includes data from April 2015 to February 2020)
- 2020-March-20: appended data from second dataset submission (monitoringMC_02).

Version 3:
(version 3 includes data from April 2015 to December 2022)
- replaced dataset with the new version, which includes all previous data and extends the sampling period to December 2022;
- converted dates to ISO 8601 format and added a column for UTC time zone;
- renamed fields to comply with BCO-DMO naming conventions.
