Deals with different types of suspended sediment load samplers. These samplers are classified according to their mode of operation into two general types: 'instanteneous' and 'time-integrating'. The 'time-integrating' samplers may be again divided into 'point-integrating' ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
