This document contains a discussion about the issues involved with the data collection process and in particular, the differences in survey methods across platforms (e.g. boat, plane, vantage point). Related platform-based issues about the observation process (and associated imperfect detection) for the data collection, and the associated need to correct observed counts prior to input for analysis are also outlined. A description of the methods comparison process and the associated results then follow, along with recommendations based on the results contained therein. Two worked examples (based on the recommended approach) provide not only a suggested approach to analysis, but also offer signposts that consumers of analyses can use to assess reliability of the results.

In addition to this guidance document we have produced a literature review related to statistical modelling of animal distribution in the UK marine renewable industry. Based on the evaluation presented in the guidance document, we have also produced software for the assessment of animal distribution.
