IODP Expedition 378 Compressional strength (penetrometer)

, 2022
Compressional strength was measured on section halves using a Humbolt Manufacturing Pocket Penetrometer. The penetrometer is only suitable for sediment not affected by cementation (i.e., saturated, clay-rich, soft sediment).

Cone Penetrometer Off-Surface Sensor [PDF]

, 1999
Cone penetrometer technology accounts for approximately 50 percent of the subsurface drilling done at the Savannah River Site. This technology provides a means of collecting data for use in the characterization of the subsurface.

Proposal of a new evaluation system of terrain trafficability for wheeled vehicles measured by the telescopic penetrometer

Archives of Transport
In most areas of human activity where vehicles are used, ensuring their mobility is important. One of the components addressed in the framework of mobility is also the movement of vehicles in the field.

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

Ibis, Volume 168, Issue 3, Page 876-889, July 2026.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

On the evaluation of pre-consolidation pressure of undisturbed saturated clays

HBRC Journal, 2017
The objective of this research was to show the effect of sample disturbance on the values of pre-consolidation pressure бc by using Schmertmann method. A prediction of бc form pocket penetrometer is also achieved.

Farming practices and their effect on soil moisture and penetration resistance: Impact on maize yields in rainfed agriculture

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract In sub‐Saharan Africa, there is growing interest in conservation agriculture practices, including reduced tillage (e.g., ripping), residue retention, and crop diversification, but their effects on soil moisture and penetration resistance in sub‐humid regions remain unclear.
