Statement

Methodology:

Feeding was assessed visually by SCUBA divers. Individuals or colonies of selected benthic species were scored for the number visible and the number of those that were feeding. Feeding was assessed by the extent to which feeding tentacles were visibly extended into the water, and for some species a distinction was made between full and partial extension of the feeding tentacles. Data were stored in a simple flat-field database. At the end of the study the data were validated and analysed with standard statistical software to determine seasonal and interannual variability in feeding activity.

Note: for species Laternula elliptica and Edwardsiella sp the Observed and Partial columns contain -9999, indicating missing data. In these species non-feeding individuals were entirely invisible so the data recorded were simply the number of individuals observed feeding within the fixed quadrat on that date.

Data quality:

Suspension feeding benthos are sensitive to disturbance, and may retract their feeding tentacles if disturbed by an observer or passing predator. A small number of cases where this may have influenced the data are indicated in the comments section of the data set.
