    dct:description """This data is from the 2024 Llyn Horse Mussel (Modiolus modiolus) Multibeam Echosounder Survey (MBES). 

The work was carried out by Binnies/Hydrofix funded by Nature Networks as part of an investigation into the decline observed at the reef. Both reefs were mapped to International Hydrographic order (IHO) 1a or higher. 

The data was processed and analysed to produce bathymetric surfaces; backscatter mosaics; a seabed classification, including the extents of the mussel beds; and measurements of the mussel bioherms.  The results from the 2024 survey were then compared to previous datasets, provided by NRW, from 2005, 2008 and 2015, all of which were analysed and reprocessed.""" ;
