Description:

Abstract:

This dataset contains level, temperature, and conductivity data collected by scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) to investigate submarine groundwater discharge on the West Florida Shelf at sample sites located in three areas of Florida: Indian Rocks Beach (IRB), Nature Coast near Hudson (NC), and Venice Headlands near Venice (VH). These data were collected using Solinst LTC 5 (serial number starting with 108) and LTC Edge (serial number starting with 107) leveloggers deployed in offshore groundwater wells on the West Florida Shelf. The dataset is a time series of submarine groundwater discharge parameters including water temperature (degrees Celsius [°C]), pressure (centimeters of water [cmH2O]), and conductivity (millisiemens per centimeter [mS/cm]). Each parameter was measured every fifteen to twenty minutes (varies by logger) for 24-hour time periods throughout the duration of deployment. Data included in this data release correspond to USGS Field Activity Number (FAN) 2022-340-FA, with associated events spanning over one year (November 2022 to February 2024) and are distinguished by alternative FANs (altFANs) or events of 22WFS05, 23WFS01, 23WFS02, 23WFS03, 23WFS04, 24WFS01.

Purpose:

This dataset was acquired to assist USGS staff with the quantification, analysis and interpretation of geochemical time series data that will ultimately be used in assessments and research of or related to submarine groundwater discharge.

Supplemental_Information:

All sampling activities correspond to the USGS Field Activity Number 2022-340-FA. Additional survey and data details are available from the USGS Coastal and Marine Geoscience Data System (CMGDS) at https://cmgds.marine.usgs.gov/services/activity.php?fan=2022-340-FA.

Process_Description:

Solinst Levelogger Description: The Solinst Levelogger measured water level (pressure above the sensor), temperature (at the sensor), and conductivity (at the sensor). The levelogger uses a Piezoresistive Silicon with Hastelloy Sensor for measurement of level; Platinum Resistance Temperature Detector (RTD) for measurement of water temperature; and 4-Electrode Platinum sensor for measurement of conductivity. The resolution for each parameter was 0.001% full scale [FS] to 0.0006% FS, 0.003 C, and 0.1 mS/cm), respectively. The logger was calibrated using a 12880 μS/cm conductivity solution prior to deployment. The logger was checked prior to each deployment using a 50000 μS/cm conductivity solution.

Process_Step:

Process_Description:

Data Storage and Preprocessing: Solinst LTC Dataloggers were retrieved and deployed in correspondence with the Field Activity Number 2022-340-FA with alternative FANs 22WFS05, 23WFS01, 23WFS02, 23WFS03, 23WFS04, and 24WFS01 (Chestang and others, 2025). All loggers used in study were assessed for proper in air values (i.e., atmospheric pressure in cm of water, air temperature, and conductivity of air ~0 millisemens per centimeter) prior to first deployment in November 2022. Dataloggers or loggers, henceforth, were deployed and retrieved from submerged, marine wells by divers equipped with Self-Contained Underwater Breathing Aparatus (SCUBA). Previously deployed loggers were retrieved prior to sampling and newly deployed loggers were installed following sampling as described by Chestang and others (2025). Deployed loggers were programed using Solinst Levelogger Software 5 prior to each trip; retrieved loggers were returned to land and downloaded onto a field laptop using Solinst Levelogger Software 5 as .xle files and exported as a comma separated value (CSV) file. All original data are provided in the csv files provided in this data release.

Process_Step:

Process_Description:

Advanced Data Processing: CSV files were imported into Microsoft Excel and data inspected for quality assurance and control reasons. Offsets (nearly instantaneous change exceeding factory parameter resolution), were compared to other sensor data and ancillary field observations (Chestang and others, 2025) and, when appropriate, were corrected using an constant offset (+/-) (Wagner and others, 2006; Smith and others, 2008). Oscillations were corrected using a ten point running mean for the duration of the observed instability (Wagner and others, 2006). Only Conductivity and temperature were processed using offset and smoothing; original data are included in the data release files for comparison. Water level or pressure remain unprocessed; unrealistic pressure data, identified as negative water levels, were replaced with no data values (-999). All original data values are provided.
