The seabed is richer in information than we think – all we have to do is look at it the right way. Hyperspectral imaging makes it possible to perform objective mapping of habitats and sediments (e.g. waste) on the seabed.
The results can be composed into a user-friendly map.
Habitat mapping
- identifies species and types of habitat
- provide mapping of dead and living zones in coral reefs
- time series
- results delivered a simple, user-friendly map (GIS format) enabling control of whole areas
Sediment mapping
- shows the spread of waste and sediments
- shows changes over time
- results are delivered as a map (GIS format)
Hyperspectral seabed mapping
All organisms, objects and sediments have their own hyperspectral fingerprint. Our technology uses them to identify and map the occurrence and spread of sediments and organisms on the seabed.
Using machine learning and our own software, we objectively and efficiently analyse data gathered in a simple-to read GIS format map.
Overview means control
Our solution identifies which organisms, species and sediments are present and their extent in the whole area of interest. Whether it’s the seabed under a fish farm, a drilling location, an area designated for pipeline-laying or other structures, you can make better decisions and show both authorities and customers objective assessments of the environment.
Ecotone maps habitats such as:
- sponge occurrences (incl. deep water concentrations of sponge)
- coral forests
- coral reefs
- excavating megafauna on soft bed
- lime algae deposits
- seaweed
- various other hard- and soft bed areas
Data from the light reflected of the corals is compiled into a hyperspectral image.
On the image above a benthic species have been detected and highlighted to show the distribution of the species.
Overview of large areas
Our results are reported as user-friendly digital maps (GIS). The maps give a representation of your entire area of interest -for instance on the seafloor below an aquaculture facility or at an offshore drilling location.
A detailed insight into the conditions at the seafloor, makes you fit for wise decision making, and enables you to deliver deliberate considerations on the seafloor environmental status to customers or authorities.
Seabed mapping for aquaculture locations
Seabed monitoring near the fish farms enables assessment of potential impacts from the installations. We are currently developing a solution that makes it possible to document seabed condition and to monitor changes over time. In contrast to point measurements from traditional grab sampling, the solution is based on larger area mapping. The technology can be used at both hard and soft seabed, exposed and protected areas and deep and shallow locations. By mapping the seabed under the nets on a regular basis, it can be possible to reduce fallow periods, as the operator will always have full control on potential changes in habitat composition and sedimentation pressure.
Hyperspectral imaging technology makes it possible to map:
- sediment spread from salmon farms (slurry, nutritional salts, food waste and faeces).
- changes in epifauna (animal life on the seabed surface)
- changes in habitat composition.
The technology is already under development and being used for a pilot project at the world’s first offshore fish farm, Ocean Farm 1. (Norwegian text)
Seabed mapping of drill cuttings
Ordinary optical inspection cannot distinguish drill cuttings from natural sediments, making it difficult to identify and monitor spread of cuttings.
Fortunately, drill cuttings have a different hyperspectral signature to natural sediments, and technology can differentiate them from each other without subjective human evaluation.
Ecotone is developing a solution able to generate a map showing the extent and environmental impact of drill cuttings.
