Differences in monthly temperature values at Similan Islands between depths and sides.

Comparisons of monthly mode, maxima, minima, range = maximum – minimum values, and negative cumulative temperature anomalies (calculated as degree days, °C d). Kruskal-Wallis ANOVA and median test followed by multiple comparisons of mean ranks for all groups (year: February 2007–February 2008 (2007) versus November 2007–November 2008 (2008), side: west (W) versus east (E), and depth: 20 m versus 7 m). (df = degrees of freedom; N = sample size; p = probability level; significance levels are *0.05>P≥0.01, **0.01>P≥0.001, ***P<0.001, n.s.: not significant).
