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: The DRAKKAR consortium as mentioned in this paper investigated the variability of the ocean circulation and water mass properties during past decades, and their effects on climate through the transport of heat through a hierarchy of high resolution model configurations based on the NEMO system.

TL;DR: In this article, the authors present the first quantitative comparison between new velocity datasets and high-resolution models in the North Atlantic subpolar gyre [1U10° Parallel Ocean Program model (POPNA10), Miami Isopycnic Coordinate Ocean Model (MICOM), 1U6° Atlantic model (ATL6), and Family of Linked Atlantic Ocean Model Experiments (FLAME)].

TL;DR: In this article, a series of sensitivity simulations with different momentum advection schemes is performed with the North Atlantic 1/4° DRAKKAR model and three second order momentum advction schemes conserving enstrophy (ens), energy (efx) and both quantities (een) are compared and their impact on the model solution are compared.

TL;DR: In this paper, the authors examined model drift in the Labrador Sea in eddy permitting model simulations using a series of configurations based on the NEMO numerical framework and showed that the drift has an advective nature.
