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:

Ventilation of the deep ocean constrained with tracer observations and implications for radiocarbon estimates of ideal mean age
TL;DR: In this article, the authors used globally gridded radiocarbon data in combination with other transient (CFCs) and hydrographic (temperature, salinity, phosphate, and oxygen) tracer data to estimate the joint distribution of age and surface origin of deep ocean waters.

Rapid Reductions in North Atlantic Deep Water During the Peak of the Last Interglacial Period
Eirik Vinje Galaasen,Ulysses S Ninnemann,Nil Irvali,Helga F Kleiven,Yair Rosenthal,Catherine Kissel,David A. Hodell +6 more
TL;DR: Using a subcentennially resolved epibenthic foraminiferal δ13C record, it is shown that the influence of North Atlantic Deep Water (NADW) was strong at the onset of the last interglacial period and was then interrupted by several prominent centennial-scale reductions.

Regional and global benthic δ18O stacks for the last glacial cycle
TL;DR: In this paper, the authors present regional stacks that characterize mean benthic δ18O change for 8 ocean regions and a volume-weighted global stack of data from 263 cores.
A novel strategy for accelerated simulation of passive tracers in ocean circulation models
S. Khatiwala,M. Visbeck +1 more
TL;DR: In this article, a novel strategy is proposed for the efficient simulation of geochemical tracers in ocean models, which captures the tracer advection and diffusion in a general circulation model (GCM) without any alteration (or even knowledge) of the GCM code.

Jenne,Dennis Joseph +21 more
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.

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.

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.
