TL;DR: In this article, a series of sensitivity tests were performed with a z-coordinate, global eddy-permitting (1/4°) ocean/sea-ice model (the ORCA-R025 model configuration developed for the DRAKKAR project) to evaluate the impact of recent state-of-the-art numerical schemes on model solutions.

TL;DR: Coordinated Ocean-ice Reference Experiments (COREs) as mentioned in this paper is a tool to explore the behaviour of global ocean-ice models under forcing from a common atmospheric dataset, which is suitable for our purposes, even though its evaluation originally focussed more on the ocean than on the sea ice.

TL;DR: In this article, the authors show that small-scale physics has a strong impact on both mesoscale physics and phytoplankton production/subduction, and that the explicitly resolved sub-mesoscales, at least smaller than one e fth of the internal Rossby radius of deformation, reinforce the mesoscaling eddies and contribute to double the primary production and subduction budgets.

TL;DR: In this article, the authors compare the raw fields of ERA40 to the CORE.v1 dataset of Large and Yeager (2004), used here as a reference, and discuss their choice to use daily radiative fluxes and monthly precipitation products extracted from satellite data rather than their ERA40 counterparts.

TL;DR: In this article, the authors present some research developments in primitive equation ocean models which could impact the ocean component of realistic global coupled climate models aimed at large-scale, low frequency climate simulations and predictions.
