The new route materialises with comparable magnitude and characteristics in three independent numerical realisations of the global ocean circulation. Its realism is supported by hydrographic data interpolated via an inverse model. The 'Tasman leakage' constitutes a sizeable component of the upper branch of the global conveyor belt and represents an extension to the prevailing views that hitherto emphasised the routes via the Drake Passage and the Indonesian Throughflow [Gordon, 1986] specialized 032MILPHY 29 10 55-1-55-4 [4 ] 2002 0094-8276 https://www.documentation.ird.fr/hor/fdi:010094745 10.1029/2001GL014586 0094-8276 [F B010094745] https://www.documentation.ird.fr/hor/fdi:010094745 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2025-08/010094745.pdf IRD - Base Horizon / Pleins textes 2015-12-01 2025-08-20 fdi:010094745 fre
