Abstract

San Salvador Island is located on an isolated carbonate platform situated on the southeastern edge of the Bahamian Archipelago. Over half of the island's small area is covered by hypersaline lakes that expose the island's water table to evaporation. Many of the island's lakes are connected to the ocean by karst conduits, thereby allowing tidal pumping to drive the exchange of fresh and saltwater during tidal cycles. To investigate the influence of tidal cycles on lake water levels, we monitored water temperature, pressure, and specific conductivity for several lakes located on San Salvador Island, Bahamas. We instrumented lakes with HOBO Onset U20L-04 loggers with a water level accuracy of 0.14 cm. HOBO Onset data loggers were set to record measurements at intervals ranging from 30 seconds to 15 minutes. We chose sampling intervals as to not exceed the HOBO logger's data recording capacity based on our estimated return to the site to download data. For most of the lakes instrumented in this study, we combine multiple timeseries into an individual location file. Accordingly, a single data table may have temporal data gaps and time periods with different sampling intervals. The README.md file included with this dataset contains a table with lake names and locations, sampling rates, and deployment dates.
