Sediment profile imaging

Sediment Profile Imaging (SPI) is a technique used to examine the layers of sediment at the bottom of water bodies like lakes, rivers, or oceans. It involves lowering a specialized camera into the sediment to capture detailed images of its structure, composition, and layering without disturbing it. This method helps scientists assess the health of aquatic environments, track pollution, and understand sediment dynamics. SPI provides valuable visual information about sediment characteristics and biological activity, aiding in environmental monitoring, management, and restoration efforts.
