Ocean Suspended Sediment Concentration Measurement Instruments

Measurements > Ocean > Ocean colour/biology > Ocean suspended sediment concentration
Measurement Definition: Parameter extracted from ocean colour observation. Indicative of river outflow, re-suspension or pollution of other-than-biological origin. Requested in both open ocean and coastal zone - Physical unit: [ g/m3 ] - Accuracy unit: [ % ] at a specific concentration (e.g., 2 g/m3).
