Habitat and Seabed Mapping

Our company has significant experience in the planning and execution of underwater surveying and mapping.  More recently, we are combining traditional mapping techniques with 3-d photogrammetry, and this is a major tool used in delivery.

The areas of mapping we have achieved ranges from a few square metres upto 100s of m2.  These areas are influenced by a number of factors including: the main objectives of the project, the depth of water, the clarity of the water, the funding/time available, and/or tidal conditions.

We have applied out techniques for mapping for a wide range of applications, from quantifying the impacts of subtidal outflows, to generating area-specific indices of the health and carbonate production capacity of tropical coral reefs.  However, this wide range can be catagorised by three main 'themes'; these are the assessment of:

  • Environmental condition, impact and recovery
  • Ecosystem condition, impact and recovery
  • Condition and layout of underwater structures

Some examples (shown opposite) of our mapping work are:

  • Seabed transects in relatively deep, low visibility, conditions
  • The layout and condition of subtidal piers and harbours
  • The assessment of the extent of coral reef damage in the Indian Ocean, and the extent of their temporal recovery
