We present a novel continuous dynamical decoupling scheme for the construction of a
robust qubit in a three-level system. By means of a clock transition adjustment, we first show …

Tracked mining vehicles (TMVs) are key equipment in deep-sea mining systems and can
easily slip when walking on soft sediments on the seabed. Thus, it is important to investigate …

This paper considers centrifuge modelling of free-fall piezocones in soft clay, and interprets
the test data to estimate the undrained shear strength and coefficient of consolidation. Data …

Cone penetration testing with pore pressure measurement (CPTU) is a cost-and time-
efficient way of collecting in situ geotechnical parameters of near-surface marine soils for …

The strength of partially saturated sand is critical for addressing engineering challenges
such as beach trafficability or coastal erosion. Mapping strength remotely would allow for …

Bottom trawling is a well-known global phenomenon and has significant physical impact on
the seabed habitat, such as compression, displacement and mobilization of the sediment …

The friction angle of sand in the nearshore zone of Cannon Beach, Yakutat, Alaska, was
estimated from the deceleration measured by a portable free-fall penetrometer (PFFP) at 72 …

Sediments in the hadal trenches have been proved to contain a large number of specific
microorganisms. In this study, we developed a pressure-retaining sampler for the hadal …

Abstract Free Fall Penetrometer (FFP) testing consist of a torpedo-shaped body freefalling
into a soil target. The use of this type of device is becoming popular for the characterization …

The societal usage of coastal zones (including offshore wind energy plants, waterway
deepening, beach conservation and restoration) is of emerging importance. Sediment …
