Fig 4. Relative frequency of sand grain sizes.

Comparisons of grain sizes of sand in 2014 and 2015 across each zone of the beach categorized by renourishment status. The five grain size categories are very coarse (V.C.), coarse (C), medium (M), fine (F), and very fine (V.F.). Statistically significant results are notated with an asterisk. * = P<0.05, ** = P<0.005, *** = P<0.0005, and indicate differences at a subsection of the beach based on renourishment status. Error bars represent the standard error of the group. In 2014 and 2015, we found a statistically significant difference in the percentage of Very Fine grains found in the renourished vs. the non-renourished sections, irrespective of beach zone.
