Sediment traps deployed on the seabed often operate unmanned for extended periods in demanding marine environments, which presents several operational challenges. Strong currents, waves, and variable seabed conditions can cause displacement, tilting, or incorrect orientation of the trap, potentially reducing the quality of the measurement data. Current influence and local turbulence may also resuspend sediments, resulting in samples that are not representative of natural sedimentation. Over time, biological fouling can affect the collection mechanism and reduce functionality.
In addition, sediment traps are exposed to risks associated with fishing gear, anchors, and other human activities, which may lead to damage or loss of both equipment and data. The lack of real-time insight means that such issues are often only detected upon recovery, while locating, servicing, and retrieving the equipment can be both time-consuming and costly.
