Short-term changes in the seawater microbiome of MS Gulf Coast
Seawater samples were collected from 7 beaches along a 48 km stretch of the Mississippi coast, USA, at noon on 4/20/2025 and at one focal beach at hourly (sunrise, noon, sunset) timescales from 04/19/2025 to 04/21/2025. DNA from filtered seawater samples were amplified targeting 250 base pairs of the V4 region of the bacterial 16S rRNA gene to determine spatiotemporal patterns in the bacterial communities.
