Comparison of annual summer V. vulnificus abundance, total bacteria, chlorophyll a concentration, salinity, and temperaturea

Study periodV. vulnificus (cells ml−1)Total bacteria (cells ml−1)Chlorophyll (μg liter−1)Salinity (ppt)Temperature (°C)
Summer 200185.7 ± 53.65.7 ± 1.8 × 1067.9 ± 1.420.3 ± 2.926.0 ± 2.1
Summer 2002210.9 ± 146.62.1 ± 0.4 × 10720.5 ± 2.225.4 ± 1.624.9 ± 3.1
  • a Values are averages ± 1 standard deviation of measurements collected from June 21 to September 21. P values indicate levels of significance as determined by Student's t test and are <0.005 for salinity and <0.001 for chlorophyll a and total bacteria except for V. vulnificus and temperature measurements, which are not significant.
