Widespread Oceanospirillaceae Bacteria in Porites spp.

Table 1

Five-day physical parameters and inorganic nutrient concentrations along the Maui reef line transect. Samples for physical and chemical analyses were collected daily along the transect for 5 days, including the four days prior to that upon which coral mucus was collected. Concentrations of each nutrient were generally similar at each of the ten quadrats, except that ammonia concentrations increased on day 2 at blocks 1–9. Each measurement was performed in triplicate.

^aHighest NTU data were registered on the last day of sampling, April 16, 2008, during a southerly swell.
^bData shown are based on one measurement on April 16, 2008. NO₃ concentrations on other days were below the method’s detection limit.
^cData shown are based on one measurement on April 13, 2008. NH₃ concentrations on other days were below the method’s detection limit.
^dStandard deviation.
All NO₂ and the majority of NO₃ concentrations in seawater were below the respective method’s detection limit.
