To reduce the maintenance cost and effort for sensors deployed in warm water that experiences intense biofouling, the sensors were set up to measure in situ seawater from an ex situ position. Water was pumped from approximately 1 m below the sea surface into the bottom spigot of a cooler that housed the sensors. To allow water outflow, a 1-inch hole was drilled at the opposite side of the spigot near the top of the cooler rim. The pump was programmed to turn on 20 minutes before each hour, pumping more than enough water to fully flush the cooler, and sensors recorded measurements on the hour. The YSI sonde was deployed directly into the Aransas Ship Channel inside a 2-inch PVC pipe at approximately 1 m below the sea surface. Funding for sensors and sensor deployment came from United States Environmental Protection Agency's National Estuary Program via the Coastal Bend Bays and Estuaries Program Contract No. 1605. This dataset is available to the public for a wide variety of uses including scientific research and analysis.
