The ponds were selected based on aerial imagery from the New Jersey Office of Geographic Information Systems (NJOGIS) and in situ physical inspection to identify ponds spanning a range of sizes (150-19,000 m2), ages (40-100+ years), and instrumentable depths (0.5-1.5 m). Data from each salt pond was collected using four Onset Computer Corp. HOBO data loggers that measured pressure, temperature, conductivity/salinity, dissolved oxygen, and pH. Each of the four sensors measured temperature, with the finalized temperature data reflecting the median of the four sensors in each pond. An additional HOBO pressure sensor was deployed in a central location recording air temperature and barometric pressure. Sensors were cleaned, calibrated, and redeployed every 4-16 weeks, and discrete dissolved oxygen and carbonate chemistry samples were collected for sensor validation at the beginning and end of each deployment (see discrete sample dataset, also in this project). This dataset presents quality controlled data from each of the five ponds across five deployments, covering a period from April 2023 to June 2024.\n\ncdm_data_type = Other\nVARIABLES:\ntime (Datetime_utc, seconds since 1970-01-01T00:00:00Z)\nsite (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\ndepth (m)\nsalinity (unitless)\ntemperature (degrees Celsius)\nDOconc (μmol/kg)\nDOeqsat (μmol/kg)\nDOsat (percent)\npH (unitless)\n | BCO-DMO | bcodmo_dataset_988873_v1 |
