In order to understand how land use and anthropogenic activities are currently impacting coral reef communities in American Samoa, I led a research team to the island of Tutuila during July of 2015. Using a diverse set of interdisciplinary methods, we gathered a wide range of samples including ground and coastal surface water samples, the tissues common marine algae, and microbial communities from biofilm and water samples from over 70 sites in four study locations. In addition, all study locations were surveyed for groundwater discharge flux (Rn gas measurements) and the physical properties of the water column (salinity, temperature, and depth) were measured.
Back at the University of Hawaii at Manoa, we are currently processing our samples in the lab. Due to lengthy processing time and cues at various analytical labs, we only have some preliminary data available at this time.
