Understanding changes in ocean circulation during the last deglaciation is crucial to unraveling the dynamics of glacial-interglacial and millennial climate shifts. We used neodymium isotope measurements on postdepositional iron-manganese oxide coatings precipitated on planktonic foraminifera to reconstruct changes in the bottom water source of the deep western North Atlantic at the Bermuda Ris...

Despite a real risk of overturning, for the Self-Propelled agricultural Machinery (SPM) the ROPS approach to protect the driver is rather recent. Due to the several SPM categories available on the market, characterized by very different mass, dimension and working functions, the fitting of a ROPS and consequently the check of its strength is complicated. The SPM could be preliminarily divided i...

Abstract. The response of the Atlantic Meridional Overturning Circulation (AMOC) to freshwater perturbations critically depends on its mean state. Large swaths icebergs melting in North during last deglaciation constituted such and can, thus, provide important constraints stability AMOC. However, AMOC state Last Glacial Maximum (LGM), preceding rapid disintegration ice sheets deglaciation, as w...

On the night of 18–19 October 2018, sodium resonance lidar measurements show presence overturning in mesospheric layer. Two independent tracers, mixing ratio and potential temperature, derived from Rayleigh measurements, reveal that vertical spreading contours a layer convective instability coincide with this overturning. Analysis also reveals gravity waves propagate upward, are saturated, diss...

Abstract: Situ Bagendit is one of the natural tourism areas in Garut Regency with an area 124 Ha. Besides being a tourist attraction, Lake also suggestion for irrigation surrounding area. In addition to channeling irrigation, earth retaining embankments built together pedestrians must meet safety requirements stability. This study aims determine value factor embankment against slipping and over...

The mass transport in the shallow, wind-driven, overturning cells in the tropical oceans is constrained to be close to the mass transport in the atmospheric Hadley cell, assuming that zonally integrated wind stresses on land are relatively small. Therefore, the ratio of the poleward energy transport in low latitudes in the two media is determined by the ratio of the atmospheric gross static sta...

The response of the North Atlantic meridional overturning circulation (MOC) to wind stress forcing is investigated from an observational standpoint, using four time series of overturning transports below and relative to 1000m, overlapping by 3.6 yr. These time series are derived from four mooring arrays located on the western boundary of the North Atlantic: the RAPIDWestern Atlantic Variability...

The ocean’s overturning circulation is inherently three-dimensional, yet modern quantitative estimates of the overturning typically represent the subsurface circulation as a two-dimensional, two-cell streamfunction that varies with latitude and depth only. This approach suppresses information about zonal mass and tracer transport. In this article, the authors extend earlier, zonally averaged ov...

Abstract Bridge resilience is a newly proposed bridge design criterion that involves robustness, redundancy and reparability targeting on the rapidity of functionality restoration after suffering extreme actions long-term durability deterioration. It stipulates lower probability reaching ultimate limit state or strength state, which have been only partly involved in codes around world. In AASHT...
