Abstract: We propose an unmanned core sediment sampling system that consists of an Unmanned Surface Vehicle (USV) and a sediment sampler (USS) to collect sediment in surface water environments such as rivers, streams, lakes, ponds, and reservoirs. The coring system of the USS is monitored by sensors measuring its positions and the forces it exerts, allows for the sample to be extracted with minimal disruption to the integrity of the sample core. We present the physical specification of the USV and USS and evaluate the system by conducting a field experiment.
