Abstract: A device for measuring ground penetration resistance that can perform this type of measurements with a hydrostatically compensated tip. Measurements of penetration resistance use a hydraulic compensated cone, which addresses the issue of very soft sediments at high water depths. The cone includes a floating tip, a body, a housing and a sleeve. Low viscosity oil fills the internal cavity between the tip and the core. A differential pressure transducer located at the top of the cone body determines the difference between the insertion related pressure and the background water pressure. This system compensates for this pressure difference using the pore fluid during insertion instead of the water column, which results in greater accuracy.

Abstract: A hybrid, modularized, tailored and re-configurable distributed monitoring and characterization device for bodies of water and sediments, including oceans, lakes, rivers, and water reservoirs. The device includes individual nodes, which are deployed as either a stand-alone or networked system. Each node is a multi-physics and multi-purpose piece of equipment with electronics and sensors configured into different modules which interconnect similar to building blocks. The device provides two housing options: a hard shell housing option for shallow water and an oil-filled soft shell housing scheme for deep water.
