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: In this article, a new surface-atmospheric dataset for driving ocean-sea-ice models based on Japanese 55-year atmospheric reanalysis (JRA-55), referred to here as JRA55-do, is presented.
Eddy-permitting ocean circulation hindcasts of past decades
Bernard Barnier,Laurent Brodeau,Julien Le Sommer,Jean-Marc Molines,Thierry Penduff,Sébastien Theetten,Anne-Marie Tréguier,Gérard Madec,Arne Biastoch,Claus W. Böning,Joachim Dengg,Sergei K. Gulev,Romain Bourdallé-Badie,Jérôme Chanut,Gilles Garric,S.G. Alderson,Andrew C. Coward,Beverly A. de Cuevas,Adrian L. New,Keith Haines,Gregory C. Smith,Sybren Drijfhout,Wilco Hazeleger,Camiel Severijns,Paul G. Myers +24 more
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 revisit the challenges and prospects for ocean circulation models following Griffies et al. (2010), and summarize new developments in ocean modeling, including: how new and existing observations can be used, what modeling challenges remain, and how simulations can also be used to support observations.

Antarctic icebergs melt over the Southern Ocean: Climatology and impact on sea ice
Nacho Merino,Nacho Merino,Julien Le Sommer,Julien Le Sommer,Gaël Durand,Gaël Durand,Nicolas C. Jourdain,Nicolas C. Jourdain,Gurvan Madec,Pierre Mathiot,Jean Tournadre +10 more
TL;DR: In this paper, a model-based seasonal climatology of iceberg melt over the Southern Ocean using state-of-the-art observed glaciological estimates of the Antarctic mass loss is proposed.
