Results of a Study into the Use of Transects to Identify the Broad-Scale Attributes of the Mawddach Estuary. (1999 CCW Marine Monitoring Trials)
The purpose of this data capture was to investigate the feasibility of using a transect based methodology to determine the proportion of muddy communities and the zonation of muddy communities from upper to lower shore. The Mawddach is one of the best examples of a small, drying, bar-built estuary in Britain and, with its mountainous catchment area it has some of the lowest nutrient inputs in Wales. In order to be able to report on the condition of the estuary a number of attributes have been identified which require monitoring. The aims of this project was to investigate the feasibility of using a transect based methodology to determine the proportion of muddy communities and the zonation of muddy communities from upper to lower shore.

Four transects were established to cover the majority of saltmarsh and intertidal biotopes present. Groups of core samples were collected at 25 m intervals along the transect. At each sample point sediment surface features and profile were described and photographed and the conspicuous species and morphological characteristics noted. The eight cores collected from each sample station were pooled and the infauna subsequently processed. The fauna present, identified to species level, were recorded on a spreadsheet as were the results of analysis of particle size characteristics of the granulomatric sample. The infaunal and granulometric data were then processed to identify the biotopes.
