Basic Hydrodynamic Parameters (Pressure, Temperature, and Conductivity) From Marine Groundwater Wells Along the West Florida Shelf Collected From November 2022 to March 2024 Associated with Field Activity Number 2022-340-FA

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. Additional data from this FAN are published in Chestang and others (2025).
