A parameterization for the restratification by finite-amplitude, submesoscale, mixed layer eddies, formulated as an overturning streamfunction, has been recently proposed to approximate eddy fluxes of density and other tracers. Here, the technicalities of implementing the parameterization in the coarseresolution ocean component of global climate models are made explicit, and the primary impacts...

Holocene ocean circulation is poorly understood due to sparsity of dateable marine archives with submillennial-scale resolution. Here we present a record of mid-depth water radiocarbon contents in the Northwest (NW) Pacific Ocean over the last 12.000 years, which shows remarkable millennial-scale variations relative to changes in atmospheric radiocarbon inventory. Apparent decoupling of these v...

This study analyzes 39 Atlantic and seven Pacific benthic δC records to characterize obliquity and precession responses in Atlantic overturning since 3 Ma. Regional benthic δC stacks are also analyzed. A major transition in orbital responses is observed at 1.5–1.6 Ma coincident with the first glacial shoaling of Northern Component Water. Since ∼1.5 Ma, the phases of Atlantic benthic δC records ...

Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...

Several large-scale components of the climate system may undergo a rapid transition as critical conditions are exceeded. These tipping elements also dynamically coupled, allowing for global domino effect under warming. Here we focus on such cascading events involving Greenland Ice Sheet (GIS), West Antarctica (WAIS) and Atlantic Meridional Overturning Circulation (AMOC). Using conceptual model,...

Three cases, one of bullous impetigo, one of a Mongolian spot, and one of constriction of the toe by a hair, were mistakenly diagnosed as cases of child abuse. The diagnosis of child abuse is not usually simple and requires a careful evaluation of the injuries and the family if cases are not to be either overlooked or overdiagnosed.
