The likely origin of this strong obliquity signal in \r\nsubtropical southwest Pacific SST is shown to be the southern high \r\nlatitudes, and comparison with existing SST reconstructions from \r\nthe equatorial Pacific is consistent with the communication of the \r\nsignal occurring principally by greenhouse gas forcing. In contrast \r\nto the SST reconstruction, regional hydrological cycle variability \r\n(based on the calculated local component of d18Osw change) does not \r\nshow significant coherence with obliquity after ~1000 ka. \r\nThe decoupling of the SST and hydrological cycle responses over \r\nthe mid-Pleistocene transition allows constraints to be placed on \r\nthe evolution and extent of orbitally paced fluctuations within \r\nthe coupled low-latitude ocean-atmosphere system. \r\n","author":null,"citation":"Russon, T., M.
