These studies have largely been motivated by concern for the environmental effects of the oil industry, since the diversity and composition of the macrobenthos have become one of the mainstays of marine biological effects monitoring. The purpose of this data capture was to: - Evaluate the existing macrobenthic and environmental data. - Undertake new statistical analyses of the data and to interpret the findings of these analyses. - Make recommendations for a meaningful and cost effective monitoring programme that might best be employed for regular wide-scale evaluation of biological quality in relation to a range of anthropogenic impacts.

Available data on the macrobenthic assemblages of the Milford Haven Waterway were re-analysed using the most up to date techniques such as univariate methods, distributional techniques and multivariate methods. No spatial reference were provided with data for statistical analysis. Spatial reference would have to be acquired from source data/reports. It is assumed for the purpose of metadata for this collation that samples were collected using Latitude and Longitude (WGS84).
