MESL are part of The Gardline Group of companies and therefore have the ability to offer a ‘one stop shop’ for all services including diving, environmental, geophysical, geotechnical and consultancy enabling our clients to capitalise on synergies arising across all areas.   


Design and Implementation  

Detailed client consultation will initially take place to ensure survey designs are fit for purpose providing accurate and relevant project deliverables.  We are also experienced in regulatory consultation providing advice and gaining approval for many different types of marine development.  

Surveys may be designed to collect data along transects or within quadrats that have been placed to map out the survey area.  Qualitative data will be collected by divers making in-situ observations recording all visible mega fauna within the designated area.  Simultaneously another diver will operate a hand held video to produce quality images and video of the seabed for quantitative analysis.   

Using this method important habitats such as seagrass beds, maerl beds, rocky reefs, Sabellaria spinulosa reefs, mussel and cockle beds can be accurately mapped out using a non-invasive method.  Data may be used to provide an Environmental Baseline for future monitoring or a Habitat Assessment for the designation of Marine Protected Areas and Marine Conservation Zones.  

Data Analysis and Reporting  

Our professionally trained marine biologists and benthic ecologists are experts in surveying subtidal habitats. 

We are experienced in ecological data analysis and can produce high quality scientific reports.  Reports can include:

  • Statistical analysis and interpretation of seabed imagery
  • Interpretation and correlation of visual and geophysical data
  • 3D modelling and Photogrammetry
  • Biotope classification using EUNIS and the Marine Habitat Classification for Britain and Ireland (JNCC)
  • Advice to government, industry and stakeholders on conservation status and vulnerability to impacts 
  • GIS mapping and production of fully illustrated and interactive electronic reports- expertise with both MapInfo and ArcGIS
