To protect the seabed and natural habitats, we first need to understand them. Classifying the physical, geological, chemical and biological properties of the seabed provides a baseline. This can then be used to measure the impact and effectiveness of blue carbon initiatives.
Insights from the analysis of seabed classification data are helping to maintain the integrity of marine and coastal ecosystems. Many different stakeholders rely on these insights:
We conduct seabed mapping from the coastline and hazardous shallow water to full ocean depths using a suite of hydrographic surveying technologies. We routinely use soundwaves or light to collect large amounts of bathymetry data. We also deploy multibeam, single-beam and/or side-scan sonar technologies from survey vessels, uncrewed surface vessels or remotely operated vehicles, as well as lidar technologies from light aircrafts or drones. To add value for our clients, it is common practice for us to generate seabed classification maps from the bathymetry data we collect. Here’s how it works:

Having analysed the backscatter images of the seafloor to identify groups with similar reflectance values, the next step is to check that different types of material (like coarse sand, crushed shells, rock and gravel) have been identified correctly. Seabed classification activities fall into two categories:
We're constantly seeking new ways to gather and exploit valuable information using subsea robotics. One promising avenue is the use of advanced imaging technology that allows us to gain a more detailed understanding of the marine environment. An exciting development on the horizon.

One carbon credit equates to one tonne of carbon dioxide (or other greenhouse gas) that has been reduced, sequestered or avoided.
