Published reconstructions of radiocarbon in the Atlantic sector of the SouthernOcean indicate that there is a mid-depthmaximum in radiocarbon age during the Last Glacial Maximum (LGM). This is in contrast to themodern oceanwhere intensemixing betweenwater masses results in a relatively homogenous radiocarbon profile. Ferrari et al. (2014) suggested that the extended Antarctic sea ice cover duri...

The rise of an effluent emerging from the diffusers of the submarine sewage outfall of a small town (15000 PE) is numerically simulated with a model of initial dilution. Results were evaluated using the vertical distribution of faecal coliforms that were analyzed for two field surveys at the central position. In addition to that, the overturning length scale was calculated from vertical profile...

Failure of the quay walls due to earthquakes results in severe economic loss. Because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. This study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

The ocean’s overturning circulation and associated heat transport are divided into contributions based on water mass ventilation from 1) shallow overturning within the wind-driven subtropical gyres to the base of the thermocline, 2) overturning into the intermediate depth layer (500–2000 m) in the North Atlantic and North Pacific, and 3) overturning into the deep layers in the North Atlantic (N...

Abstract The climbing robot is gradually applied to the safety weld detection on large metal walls avoid manual operation. However, most robots are difficult perform efficient operations for poor performance obstacle overcoming, flexible turning and motion stability. This paper presents a robot, which integrates contact permanent magnet adsorption units crawler chain mobile mechanism obtain con...

and the gravitational acceleration g = −gẑ. While this a configuration can satisfy hydrostatic balance, infinitesimal perturbations on the interface separating the two fluids at z = H/2 will grow exponentially, leading to overturning. The energy available for overturning can be estimated by considering the fluid energetics. The average potential energy (per unit volume) of the system described ...

North Atlantic (NA) deep-water formation and the resulting Atlantic meridional overturning cell is generally regarded as the primary feature of the global overturning circulation and is believed to be a result of the geometry of the continents. Here, instead, the overturning is viewed as a global energy–driven system and the robustness of NA dominance is investigated within this framework. Usin...

Tractor overturning remains a serious problem in agricultural activities. A detailed analysis of problems and causes leading to a tractor overturn have revealed that by improving tractor’s static stability we can positively infl uence the safety as early as during the concept phase. We designed a mathematical model and a numerical simulation of the static stability of a tractor with an oscillat...

[1] Climate model simulations of the 8.2 ka event show an abrupt strengthening of the Atlantic subpolar gyre that allows us to connect two major but apparently contradictory climate events of the early Holocene: the freshwater outburst from proglacial lakes and the onset of Labrador Sea water formation. The 8.2 ka event is the largest climatic signal of our present interglacial with a widesprea...

The near-surface branch of the overturning mass transport circulation in the troposphere, containing the equatorward flow, is examined in isentropic and geometric coordinates. A discussion of the zonal momentum balance within isentropic layers shows that the equatorward flow at a given latitude is confined to isentropic layers that typically intersect the surface at that latitude. As a conseque...
