    "descript": "To assess the spatial and temporal hydrographic variability along the West Florida Shelf (including Tampa Bay and Charlotte Harbor), stable oxygen (d18O) and hydrogen (dD) isotope ratios were measured using water samples collected from across the region by the U.S. Geological Survey (USGS) and collaborators. Surface, bottom, and groundwater samples from a marine well network along the central West Florida Shelf, as well as surface, intermediate, and bottom water samples within the Tampa Bay estuary were collected from 2022 2024 during USGS Field Activity Numbers (FANs) 2022-340-FA (Chestang and others, 2025) and 2022-349-DD (Hunt, 2025; Tamborski and others, 2025). Additional samples from Tampa Bay marine and riverine surface waters were collected in 2025, corresponding to USGS FAN 2025-311-DD. This data release also includes d18O and dD data obtained by digitizing legacy data previously published by Sackett and others (1991) and Netratanawong (1995).",
