In their recent paper, Osborn et al. detail an inexpensive and compact underwater digital camera imaging system (the FlocARAZI) developed to collect in situ high resolution images of flocculated suspended sediment at depths of up to 60 meters. The full paper and a GitHub repository containing build instructions and image processing code associated with the FlocARAZI can be found below.
