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)

Reef seawater was collected to quantify microbial cell abundances. Water samples were collected by SCUBA divers approximately 2 meters above the reef surface. Physical parameters, including temperature, salinity, dissolved oxygen, pH, and turbidity, were measured from the boat using an EXO2 multiparameter sonde. Sample processing will follow previously published methods (Becker et al., 2020; Weber et al., 2020). Collections were replicated across four sampling days.
