Recommended Operating Guidelines

Most of the techniques used by habitat mappers were designed for other survey disciplines, and have well established standard operating procedures (SOPs) to provide quality data for their intended purpose. MESH at its outset undertook a Review of Standards and Protocols for Habitat Mapping (Coggan et al., 2007) (available in the Products Library as MESH Standards & Protocols) with the aim of reviewing all this existing material to assess its suitability for use in a seabed habitat mapping context. It became apparent that organisations were using the same equipment in slightly different ways, often because a user has a slightly different application for a technique from its originally intended purpose. To try and achieve some standardisation in the use of survey equipment, the MESH Project drafted a series of Recommended Operating Guidelines (ROG) to describe how best to use each technique in a marine habitat mapping context. Where applicable, standard operating procedures, ISO-standards or similar are well known and recognised, references and links are made. The ROGs cover four main areas:

 
  • Guidelines for mapping intertidal and shallow subtidal habitats by remote and on-site surveys, showing how to collect, manage and verify data.

 

  • Standards and protocols for the use and ground-truthing of remote sensing imagery, both satellite and aerial (e.g. SPOT, CASI and LiDAR).

 

  • Guidelines for mapping deeper sub-tidal habitats (e.g. 20 – 200 m depths) by remote and on-site surveys, showing how to collect, manage and verify data.

 

  • Standards and protocols for the use and ground-truthing of acoustic techniques (e.g. side-scan sonar, multibeam sonar, Acoustic Ground Discrimination Systems and their associated ground-truthing methods (e.g.underwater video, and sediment sampling).

 

The ROGs are listed for download below. In 2012 the MESH Atlantic Project updated the LiDAR and Side-scan sonar ROGs and produced a new ROG for grab sampling.
