New England Results: The following charts show the
average number of individuals found in
each taxa group at a given depth for Rye and Nahant.
  For data collected in New England, a two way ANOVA with replication was run to determine which variables (location and depth) had a significant impact on the variation. For crustacea, nematoda, and turbellaria location was found to be significant (with p values of 0.039, 0.0001, and 0.028 To compare diversity Shannon's index was calculated for both Rye and Nahant. For Rye Shannon's index was equal to 0.648 and for Nahant it was 1.001. respectively) but depth was not. For annelida neither location nor depth were found to be a significant source of variation. |

| Bermuda Results: The following charts show the
average number of individuals found in
each taxa group at Whalebone and Tobacco Bay by the vertical location
on the beach in which they were collected.
  The data collected at Whalebone and Tobacco Bay could not be compared to each other since the collections were not done consistently. Regressions done on the data collected at each site did not show any significant correlation between vertical location of the sediment sample and the amount and type of organisms found. The Shannon index was calculated for both locations. For Whalebone it was 1.60 and for Tobacco Bay it was 1.28. |
