CERMES research on sargassum covers a number of areas, including modelling and prediction of influxes, using drones and GIS to monitor and map influxes, the impact on fisheries, as well as the challenges and potential opportunities in managing sargassum influxes. We expect that new research and publications to be forthcoming as work advances.

We invite you to browse available publications and presentations below.  If you refer to any of these in your work, we ask that you cite them appropriately.

Using drones and GIS to monitor and map Sargassum
Since 2018, CERMES has been testing and comparing the use of ‘off-the-shelf’ recreational drones (or unmanned aerial vehicles, UAVs) equipped with a RGB camera payload, together with drone flight planning mobile application and cloud-based photogrammetry mapping software, as a tool for rapidly monitoring and detecting sargassum remotely. Remote sensing and standard geospatial techniques were then leveraged to map, classify and quantify the abundance of stranded sargassum. Conventional transect and quadrat surveys were simultaneously conducted to validate results of the drone mapping methodology and geospatial analyses.
This research has been presented at the 39th Annual AMLC Meeting and GCFI72
Application of drone technologies in quantifying stranded Sargassum

The work of SargAdapt will build on this research to mainstream the use of this approach of this technology for monitoring sargassum through the development of a standard monitoring protocol combined with strategic provision of resources and training in its application.
