Arthur T Knackerbracket has found the following story:
The oceans are the largest global heat reservoir. As a result of man-made global warming, the temperature in the global climate system increases; around 90% of the extra heat is absorbed by the oceans. This means that the average sea temperature can tell us a lot about the state of our climate, both today and in the past. However, it is difficult to determine an accurate average value across all sea depths and regions of the world.
The results of previous measurement methods heavily depend on location, season or sea depth, which can lead to distorted results. As part of the WAIS Divide Ice Core Project, an international research team led by Bernhard Bereiter from the Scripps Institution of Oceanography - now working at Empa and the University of Bern - has developed a method of measuring ocean temperatures over the last 24'000 years with high accuracy.
These measurements have now been published in Nature. "Our study clearly shows that the basic idea - the connection between the concentration of noble gases in the atmosphere and the average ocean temperature - is correct and that the method works," said Bereiter.

Actually, the report from Nature [nature.com] confirms this study is definitely about mean ocean temps overall, not ocean surface temp. So that may be a significant difference. Do you have studies that claim a full degree rise in the deep oceans in recent years? Because I don't think I've seen predictions of that magnitude.
