text: Since the complex models have failed in this respect, and since there are insufficient deep-ocean observations to provide reliable quantitative evidence of the putative heat accumulation below 2000 m, still less to determine the mechanism of the imagined heat transfer, still less again to apportion duly the respective contributions of anthropogenic, solar and subsea volcanic influences on the benthic heat accumulation, it is surely unreasonable for our simple model to be expected to do what the complex models have self-evidently failed to do and what cannot be done by any model, simple or complex, unless and until measurements of far higher resolution than is now to hand become available at all points of the oceanic column. For instance, the 3500 automated Argo bathythermograph buoys have a resolution equivalent to taking a single temperature and salinity profile in Lake Superior less than once a year: and before Argo came onstream in the middle of the last decade the resolution of oceanic temperature measurements was considerably poorer even than that, especially in the abyssal strata.
