©2020 Biological and Chemical Oceanography Data Management Office.Comprehensive multi-parameter, water-quality monitoring sondes designed for long-term monitoring, profiling and spot sampling. The EXO sondes are split into several categories: EXO1 Sonde, EXO2 Sonde, EXO3 Sonde. Each category has a slightly different design purpose with the EXO2 and EXO3 containing more sensor ports than the EXO1. Data are collected using up to four user-replaceable sensors and an integral pressure transducer. Users communicate with the sonde via a field cable to an EXO Handheld, via Bluetooth wireless connection to a PC, or a USB connection to a PC. Typical parameter specifications for relevant sensors include dissolved oxygen with ranges of 0-50 mg/l, with a resolution of +/- 0.1 mg/l, an accuracy of 1 percent of reading for values between 0-20 mg/l and an accuracy of +/- 5 percent of reading for values 20-50 mg/l. Temp ranges are from-5 to +50 degC, with an accuracy of +/- 0.001 degC. Conductivity has a range of 0-200 mS/cm, with an accuracy of +/-0.5 percent of reading + 0.001 mS/cm and a resolution of 0.0001 - 0.01 mS/cm.

|---|---|---|
| Water quality metrics collected from 10 meter reefs from around the U.S. Virgin Islands during April 2022 (Multi-scale multi-host disease spread project) | A YSI EXO Sonde (YSI Inc./Xylem Inc.) was deployed from the ship at 10 meters to measure temperature, salinity, dissolved oxygen, pH, and turbidity at each reef site from the research vessel. | YSI EXO Sonde (YSI Inc./Xylem Inc.) |
| Water quality metrics collected from 25 meter reefs from around the U.S. Virgin Islands during May 2023 (Multi-scale multi-host disease spread project) | At each sampling location, we collected reef seawater for water quality metrics: the microbial community of the surrounding environment, inorganic nutrient concentrations, the total organic carbon and total nitrogen, and cell abundances. Sample processing will be conducted using previously published methods (Becker et al., 2020; Weber et al., 2020). Water was collected via SCUBA 2 meters above the reef. From the boat, we used an Exo2 multiparameter sonde to measure temperature, salinity, dissolved oxygen, pH, and turbidity. Each experimental site had replicate sampling events on two different days. | YSI EXO Sonde (YSI Inc./Xylem Inc.) |
