TITLE=Characterization and classification of estuarine suspended particles based on their inorganic/organic matter composition JOURNAL=Frontiers in Marine Science VOLUME=Volume 9 - 2022 YEAR=2022 URL=https://www.frontiersin.org/journals/marine-science/articles/10.3389/fmars.2022.896163 DOI=10.3389/fmars.2022.896163 ISSN=2296-7745 ABSTRACT=A 13h survey was performed on the 17th of September 2014 in the Rhine region of Freshwater Influence (Rhine-ROFI) about 10 km downstream of the mouth of the Rotterdam Waterway during calm weather conditions. Suspended Particle Matter (SPM) measurements were performed during a full tidal cycle, near the seabed, at neap tide, and samples were taken at 0.6 m above meter for on-board analysis. The measurements were performed with (a) a LISST 100X submersible particle size analyzer, (b) a LISST-HOLO a submersible digital holographic camera, (c) a home-made underwater camera and (d) an on-board LabSFLOC2 video microscopy equipment that used in-situ collected samples.
