TLDR
In this paper, a global ocean circulation model, forced to least-square consistency with modern data, is used to find lower bounds for the time taken by surface-injected passive tracers to reach equilibrium.About:

Oceanic vertical mixing: a review and a model with a nonlocal boundary layer parameterization
TL;DR: In this article, a new parameterization of oceanic boundary layer mixing is developed to accommodate some of this physics, including a scheme for determining the boundary layer depth h, where the turbulent contribution to the vertical shear of a bulk Richardson number is parameterized.

Feedback between deglaciation, volcanism, and atmospheric CO2
TL;DR: In this paper, an evaluation of the historical record of volcanic eruptions shows that subaerial volcanism increases globally by two to six times above background levels between 12-ka and 7-ka, during the last deglaciation.

TL;DR: This work presents a stricter approach to improve intercomparison of palaeoclimate sensitivity estimates in a manner compatible with equilibrium projections for future climate change, and reveals a climate sensitivity over the past 65 million years of 0.3–1.9 at 95% or 68% probability.

TL;DR: In this article, a stricter approach was proposed to improve intercomparison of palaeoclimate sensitivity estimates in a manner compatible with equilibrium projections for future climate change, which revealed a climate sensitivity (in K W -1 m 2) of 0.3-1.9 or 0.6 -1.3 at 95% or 68% probability, respectively.

Eddy Saturation of Equilibrated Circumpolar Currents
TL;DR: In this paper, the authors used a sector configuration of an ocean general circulation model to examine the sensitivity of circumpolar transport and meridional overturning to changes in Southern Ocean wind stress and global diapycnal mixing.

TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

Isopycnal mixing in ocean circulation models
TL;DR: In this paper, a subgrid-scale form for mesoscale eddy mixing on isopycnal surfaces is proposed for use in non-eddy-resolving ocean circulation models.

A finite-volume, incompressible Navier Stokes model for studies of the ocean on parallel computers
TL;DR: A preconditioner is used which, in the hydrostatic limit, is an exact integral of the Poisson operator and so leads to a single algorithm that seamlessly moves from nonhydrostatic to hydrostatic limits, competitive with the fastest ocean climate models in use today.
