How can we assess the impact of ash clouds from the La Soufrière volcanic eruptions on sargassum prevalence around Jamaica?

Data are being collected in Jamaica to assess the impact of ash clouds from the La Soufrière volcanic eruptions on sargassum prevalence around Jamaica, as part of the MONISARG project. Mona GeoInformatics Institute (MGI) in Kingston Jamaica, have conducted five (5) beach surveys evaluating the volume and area of beached Sargassum in August 2021. Monitoring…
