What's new in NEMO's use and development from the Consortium's institutions NOC operates on two sites in the UK: Southampton: Global ocean models and open ocean processes Liverpool: Regional ocean models and coastal ocean processes Both sites work, in collaboration with UKMO, on Earth System Modelling Global models include the Drakkar suite (ORCA1, ORCA025 and ORCA_R12) Regional models include 1/12 o Northern North Atlantic and Pan-Arctic configurations A number of NEMO-based projects involve NOC researchers including: MESoscale Ocean eddies and CLImate Predictability Ships and Waves Reaching Polar Regions Ocean Surface Mixing - Ocean Sub-mesoscale Interaction Study OSMOSIS

What's new in NEMO's use and development from the Consortium's institutions New XIOS features and robustness tested in 1/12 o Global model with up to 10k cores NEMO-ICB: interactive icebergs in the NEMO ocean model globally configured at coarse and eddy-permitting resolution. Marsh et al 2014, submitted GMD (next slide) Contributions to the configuration toolkit (James Harle) Development of biogeochemical component (MEDUSA) and century-long runs in ORCA025 Applications of recent developments
